An attack aircraft , strike aircraft , or attack bomber is a tactical military aircraft that has a primary role of carrying out airstrikes with greater precision than bombers , and is prepared to encounter strong low-level air defenses while pressing the attack. This class of aircraft is designed mostly for close air support and naval air-to-surface missions, overlapping the tactical bomber mission. Designs dedicated to non-naval roles are often known as ground-attack aircraft .
139-678: The LTV A-7 Corsair II is an American carrier-capable subsonic light attack aircraft designed and manufactured by Ling-Temco-Vought (LTV). The A-7 was developed during the early 1960s as replacement for the Douglas A-4 Skyhawk . Its design was derived from the Vought F-8 Crusader ; in comparison with the F-8, the A-7 is both smaller and restricted to subsonic speeds, its airframe being simpler and cheaper to produce. Following
278-407: A "low transition", where the aircraft was intentionally held in "ground effect" a few feet off the runway during gear retraction, and as much as a 10 mi (16 km) departure at treetop altitude before reaching a safe flap-retraction speed. (A-7A wing flap systems were either fully extended or fully retracted. The A-7A flap handle did not have the microswitch feature of later models that permitted
417-603: A 102mm anti-ship cannon, The BK 7,5 was unsurpassed as an aircraft-fitted gun until 1971, when the four-engine Lockheed AC-130 E Spectre; equipped with a 105 mm M102 howitzer , entered service with the US Air Force.) In the immediate post war era the piston-engined ground-attack aircraft remained useful since all of the early jets lacked endurance due to the fuel consumption rates of the jet engines. The higher powered piston engine types that had been too late for World War II were still capable of holding their own against
556-450: A battlefield, their slower speeds made them extremely vulnerable to ground fire, as did the lighter construction of fighters. The survivability of attack aircraft was guaranteed by their speed/power, protection (i.e. armor panels) and strength of construction; Germany was the first country to produce dedicated ground-attack aircraft (designated CL-class and J-class ). They were put into use in autumn 1917, during World War I. Most notable
695-605: A class of Schlacht ("battle") aircraft, such as the Henschel Hs 123 . Moreover, the experiences of German Condor Legion during the Spanish Civil War , against an enemy with few fighter aircraft, changed ideas about ground attack. Though equipped with generally unsuitable designs such as the Henschel Hs 123 and cannon -armed versions of the Heinkel He 112 , their armament and pilots proved that aircraft were
834-598: A competitive bid by Vought in response to the United States Navy 's (USN) VAL (Heavier-than-air, Attack, Light) requirement, an initial contract for the type was issued on 8 February 1964. Development was rapid, first flying on 26 September 1965 and entering squadron service with the USN on 1 February 1967; by the end of that year, A-7s were being deployed overseas for the Vietnam War . Initially adopted by USN,
973-496: A dramatic increase in fuel efficiency compared with earlier turbojets—the A-7D was said to have specific fuel consumption one sixth that of an F-100 Super Sabre at equivalent thrust. An A-7D carrying twelve 500 lb (230 kg) bombs at 480 mph (770 km/h) at 33,000 ft (10,000 m) used only 3,350 lb (1,520 kg) of fuel per hour. Typical fuel consumption at mission retrograde during aircraft carrier recovery
1112-604: A high altitude bomber escort, but gradually found that role filled by the North American P-51 Mustang (because of its much longer range and greater maneuverability). The P-47 was also heavier and more robust than the P-51 and regarded therefore, as an " energy fighter ": ideal for high-speed dive-and-climb tactics, including strafing attacks. Its armament of eight 0.50 caliber machine guns was effective against Axis infantry and light vehicles in both Europe and
1251-404: A lack of Air Force enthusiasm for the ground-attack role, developed the dedicated attack helicopter . On 17 January 1991, Task Force Normandy began its attack on two Iraqi anti-aircraft missile sites. TF Normandy, under the command of LTC Richard A. "Dick" Cody , consisted of nine AH-64 Apaches , one UH-60 Black Hawk and four Air Force MH-53J Pave Low helicopters. The purpose of this mission
1390-675: A light aircraft mixing all the roles that required extensive communication with land forces: reconnaissance, liaison, artillery spotting , aerial supply, and, last but not least, occasional strikes on the battlefield. The concept was similar to front-line aircraft used in the World War I, which was called the CL class in the German Empire. Eventually the RAF's experience showed types such as Westland Lysander to be unacceptably vulnerable and it
1529-700: A light attack aircraft. The Soviets' similar Sukhoi Su-25 ( Frogfoot ) found success in the "flying artillery" role with many air forces. The UK has completely retired the BAE Harrier II in 2011, and the Panavia Tornado dedicated attack-reconnaissance aircraft in 2019. It obtained the F-35 in 2018 and it retains its fleet of Eurofighter Typhoon multirole fighters.

#17327801143791668-646: A perceived urgency to getting the type into service. On 14 October 1966, enough aircraft had been delivered to the Navy that the first squadron could be formed. The first A-7 squadrons attained operational status on 1 February 1967; these were able to commence overseas combat operations in the escalating Vietnam War during December of that year. The June 1964 contract had ordered the completion of seven development aircraft and 35 production-standard fighter bombers. A follow-up contract, placed during September 1965, ordered 140 more aircraft. A third contract for 17 aircraft led to
1807-543: A permanent USAF A-7D presence in Southeast Asia. A-7Ds from both wings stationed at Korat engaged in combat operations in Cambodia until 15 August 1973 when an A-7D of the deployed 353d TFS/354th TFW carried out the last air support mission. In March 1974, the 354th TFW transferred several more aircraft to the 3d TFS prior to its return to Myrtle Beach AFB. The USAF A-7D flew a total of 12,928 combat sorties during
1946-467: A pilot and a naval flight officer in an adversary electronic warfare role. Pilots of the early A-7s lauded the aircraft for general ease of flying (with the exceptions of poor stability on crosswind landings and miserable stopping performance on wet runways with an inoperative anti-skid braking system) and excellent forward visibility but noted a lack of engine thrust. This was addressed with A-7B and more thoroughly with A-7D/E. The turbofan engine provided

Nevertheless, NAA continued with new designs, including the T-28 Trojan trainer and attack aircraft, the F-82 Twin Mustang fighter, B-45 Tornado jet bomber, the FJ Fury fighter, AJ Savage , the revolutionary XB-70 Valkyrie Mach-3 strategic bomber , Shrike Commander , and T-39 Sabreliner business jet. The Columbus, Ohio division of North American Aviation was instrumental in
2224-410: A separate attack aircraft category was greatly diminished by the introduction of precision-guided munitions which allowed almost any aircraft to carry out this role while remaining safe at high altitude. Attack helicopters also have overtaken many remaining roles that could only be carried out at lower altitudes. Since the 1960s, only two dedicated attack aircraft designs have been widely introduced,
2363-418: A supersonic one. By foregoing a supersonic capability, the airframe could be smaller, cheaper, and easier to manufacture; considerably larger quantities of such an attack platform could be procured over a supersonic counterpart. Development speed was also increased by sticking to subsonic speeds, which was a further advantage. A particular emphasis was placed on the accurate delivery of weapons, which would reduce
2502-639: A task of converted trainers, like the BAE Systems Hawk or Aero L-39 Albatros , and many trainers are built with this task in mind, like the CASA C-101 or the Aermacchi MB-339 . Such counter-insurgency aircraft are popular with air forces which cannot afford to purchase more expensive multirole aircraft, or do not wish to risk the few such aircraft they have on light ground attack missions. A proliferation of low intensity conflicts in
2641-534: A total of 199 A-7A aircraft being manufactured. As the original version was found to be underpowered, a large order for 196 aircraft of the improved A-7B variant, equipped with the more powerful Pratt & Whitney TF30 -8 engine, was placed. Further variants of the type would be ordered, including the A-7D for the United States Air Force (USAF), during 1966. Partially due to a shortage of engines,
2780-550: A total of 535 aircraft of this variant would be manufactured. During the 1970s and 1980s, several specialised models, such as the TA-7C for training and EA-7L for electronic warfare , were developed as well. During 1983, the final delivery of a new-build A-7 took place. The LTV A-7 Corsair II was a carrier-capable subsonic attack fighter. It was a derivative of the Vought F-8 Crusader, an earlier fighter; compared to
2919-671: A two-seat A-7 trainer was developed by LTV for the Air Force, designated the A-7K. One prototype aircraft was built by modifying an existing A-7D airframe; however, production A-7Ks were new builds with 1979 and 1980 tail numbers. The A-7K was a fully combat-capable aircraft as well as a dual-control training aircraft. Most of the A-7K trainers went to the transition school at Tucson, with the squadrons' A-7Ds being re-distributed to other ANG squadrons. However, all ANG squadrons were assigned an A-7K trainer as well as their complement of A-7Ds. During

#17327801143793058-483: A very effective weapon, even without bombs. This led to some support within the Luftwaffe for the creation of an aircraft dedicated to this role, resulting in tenders for a new "attack aircraft". This led to the introduction (in 1942) of a unique single-seat, twin-engine attack aircraft, the slow-moving but heavily armored and formidably armed Henschel Hs 129 Panzerknacker ("Safecracker" /"Tank Cracker"). In Japan,
3197-426: Is considered an attack mission . In United States Navy vocabulary, the alternative designation for the same activity is a strike mission . Attack missions are principally divided into two categories: air interdiction and close air support . In the last several decades, the rise of the ubiquitous multi-role fighter has created some confusion about the difference between attack and fighter aircraft. According to

This terrorist attack was largely unreported due to the Iran hostage crisis at
3475-558: The A-7E , the definitive model of the aircraft, was specified and placed into production. This variant integrated several of the improvements of the USAF's A-7D, including the TF41 engine and much of its avionics; however, the engine was revised for slightly more thrust and the communications modified for compatibility with naval systems. On 25 November 1968, the first A-7E conducted its first flight;
3614-684: The Allison TF41 -A-2, a licensed derivative of the Rolls-Royce Spey engine, powered the A-7D. The adoption of a British engine caused some political controversy on both sides of the Atlantic . The United States Army has not been permitted to operate fixed-wing combat aircraft since the establishment of an independent United States Air Force (USAF) in 1947. To meet its need for close air support of its troops in South Vietnam,
3753-659: The F-111 "Aardvark" was designated F despite having only minimal air-to-air capabilities. Only a single aircraft in the USAF's current inventory bears a simple, unmixed "A" designation: the A-10 Thunderbolt II. British designations have included FB for fighter-bomber and more recently "G" for "Ground-attack" as in Harrier GR1 (meaning "Ground-attack/Reconnaissance, Mark 1"). Imperial Japanese Navy designation use "B" to designate carrier attack bomber such as
3892-442: The Henschel Hs 123 ). Although not a synonymous class with ground-attack aircraft, fighter-bombers were usually used for the role, and proved to excel at it, even when they were only lightly armored. The Royal Air Force and United States Army Air Forces relegated obsolescent fighters to this role, while cutting-edge fighters would serve as interceptors and establish air superiority . The United States Navy , in distinction to
4031-835: The Imperial Japanese Navy had developed the Aichi D3A dive bomber (based on the Heinkel He 70 ) and the Mitsubishi B5M light attack bomber. Both, like their US counterparts, were lightly armored types, and were critically reliant on surprise attacks and the absence of significant fighter or AA opposition. During the Winter War , the Soviet Air Forces used the Polikarpov R-5 SSS, and Polikarpov R-Z Sh, as attack aircraft. Perhaps
4170-712: The Invasion of Grenada , Operation El Dorado Canyon , and the Gulf War . The type was also used to support the development of the Lockheed F-117 Nighthawk . The A-7 was also exported to Greece in the 1970s and to Portugal in the late 1980s. The USAF and USN opted to retire their remaining examples of the type in 1991, followed by the ANG in 1993 and the Portuguese Air Force in 1999. The A-7
4309-791: The Junkers Ju 87 Stuka greatly outnumbered the Hs 129, while the Petlyakov Pe-2 was used for this role in spite of not being specifically designed for it. In the latter part of World War II, the fighter-bomber began to take over many attack roles, a transition that continued in the post-war era. Jet -powered examples were relatively rare but not unknown, such as the Blackburn Buccaneer . The U.S. Navy continued to introduce new aircraft in their A - series , but these were mostly similar to light and medium bombers . The need for

4448-1017: The Nakajima B5N Type-97 bomber although these aircraft are mostly used for torpedo attack and level bombing. They also use "D" to specifically designate carrier dive bomber like the Yokosuka D4Y Suisei . However by the end of the world war II, the IJN introduced the Aichi B7A Ryusei which could performed both torpedo bombing and dive bombing rendering the "D" designation redundant. The NATO reporting names for Soviet/Russian ground-attack aircraft at first started with "B" categorizing them as bombers, as in case of Il-10 'Beast'. But later they were usually classified as fighters ("F")—possibly because (since Sukhoi Su-7 ) they were similar in size and visual appearance to Soviet fighters, or were simply derivatives of such. In

In Germany and the USSR , where they were known as Schlachtflugzeug ("battle aircraft") or sturmovik ("storm trooper") respectively, this role was carried out by purpose-designed and heavily armored aircraft such as the Henschel Hs 129 and Ilyushin Il-2 . The Germans and Soviets also used light bombers in this role: cannon-armed versions of
4726-601: The O-47 and BT-9 , also called the GA-16. The BC-1 of 1937 was North American's first combat aircraft; it was based on the GA-16. In 1940, like other manufacturers, North American started gearing up for war, opening factories in Columbus, Ohio , Dallas, Texas , and Kansas City, Kansas . North American ranked eleventh among United States corporations in the value of wartime production contracts. North American's follow-on to

The attack aircraft as a role was defined by its use during World War I , in support of ground forces on battlefields. Battlefield support is generally divided into close air support and battlefield air interdiction, the first requiring strict and the latter only general cooperation with friendly surface forces. Such aircraft also attacked targets in rear areas. Such missions required flying where light anti-aircraft fire
5004-721: The Pacific . While machine guns and cannon were initially sufficient, the evolution of well-armored tanks required heavier weapons. To augment bombs, high explosive rockets were introduced, although these unguided projectiles were still "barely adequate" because of their inaccuracy. For the British RP3 , one hit per sortie was considered acceptable. However, even a near miss with rockets could cause damage or injuries to "soft targets," and patrols by Allied rocket-armed aircraft over Normandy disrupted or even completely paralyzed German road traffic. They also affected morale, because even
5143-720: The Panama Canal . These deployments, named "Cornet Cove" generally were of ninety (90) days, and were rotated among squadrons of the three wings in the United States. Beginning in 1977, with the phaseout of the A-7D with active-duty units, the Air National Guard began taking over this mission. During Operation Urgent Fury , various ANG units deployed A-7Ds to support Marines and the 82nd Airborne Division for contingency operations in Grenada . In December 1989,

In September, it merged with Rockwell-Standard, and the merged company became known as North American Rockwell . During this period the company continued its involvement with the Apollo program , building

The name Corsair II reflects the well-known F4U Corsair, which famously served as a capable fighter bomber in World War II and the Korean War . It was supposed to establish a lineage between the aircraft from the same manufacturer and intended for the same ground attack role. On 27 September 1965,

5838-605: The United States occupation of Haiti and Nicaragua . The United States Army Air Corps was notable for its creation of a separate "A-" designation for attack types, distinct from and alongside "B-" for bomber types and "P-" for pursuit (later replaced by "F-" for fighter) aircraft. The first designated attack type to be operational with the USAAC was the Curtiss A-2 Falcon . Nevertheless, such aircraft, including

In 1959, North American built the first of several Little Joe boosters used to test the launch escape system for the Project Mercury spacecraft . In 1960, the new CEO Lee Atwood decided to focus on the space program , and the company became the prime contractor for the Apollo command and service module , a larger Little Joe II rocket to test Apollo's launch escape system, and

Overall U.S. experience in the Gulf War , Kosovo War , Afghanistan War , and Iraq War has resulted in renewed interest in such aircraft. The U.S. Air Force is currently researching a replacement for the A-10 and started the OA-X program to procure
6394-417: The " Night Witches " utilised an obsolescent, wooden light trainer biplane type, the Polikarpov Po-2 and small anti-personnel bombs in "harassment bombing" attacks that proved difficult to counter. Wartime experience showed that poorly armored and/or lightly built, pre-war types were unacceptably vulnerable, especially to fighters. Nevertheless, skilled crews could be highly successful in those types, such as
6533-401: The 1,420 maritime strike variants of the North American B-25 Mitchell G/H, which mounted either a M4 cannon , or light-weight T13E1 or M5 versions of the same gun. These weapons, however, were hand-loaded, had shorter barrels and/or a lower muzzle velocity than the BK 7,5 and, therefore, poorer armor penetration, accuracy and rate of fire. (Except for versions of the Piaggio P.108 armed with
6672-407: The A-2's replacement, the Curtiss A-12 Shrike , were unarmored and highly vulnerable to AA fire. The British Royal Air Force focused primarily on strategic bombing, rather than ground attack. However, like most air arms of the period it did operate attack aircraft, named Army Cooperation in RAF parlance, which included the Hawker Hector , Westland Lysander and others. Aviation played a role in
6811-421: The A-7 proved attractive to other services, soon being adopted by the United States Air Force (USAF) and the Air National Guard (ANG) to replace their aging Douglas A-1 Skyraider and North American F-100 Super Sabre fleets. Improved models of the A-7 would be developed, typically adopting more powerful engines and increasingly capable avionics. American A-7s would be used in various major conflicts, including
6950-494: The A-7's higher speed was somewhat detrimental for escorting the helicopters but the aircraft's high endurance and durability were an asset and it performed admirably. On 18 November 1972, Major Colin A. Clarke led a successful CSAR mission near Thanh Hoa to rescue a downed Republic F-105 Thunderchief crew. The mission lasted a total of 8.8 hours during which Clarke and his wingman took a number of hits from 0.50 cal (12.7 mm) anti-aircraft fire. For his actions in coordinating
7089-604: The A-7. From 1967 to 1971, a total of 27 US Navy squadrons took delivery of four different A-7A/B/C/E models. The Vought plant in Dallas, Texas, employed up to 35,000 workers who turned out one aircraft a day for several years to support the navy's carrier-based needs for Vietnam and SE Asia and commitments to NATO in Europe. In 1974, when USS Midway became the first aircraft carrier to be homeported in Yokosuka, Japan, two A-7A squadrons assigned to Carrier Air Wing Five (CVW-5) were moved to NAF Atsugi , Japan. In 1976, these squadrons ( VA-93 and VA-56 ) finally transitioned to

#17327801143797228-411: The Allison TF41-A-1 turbofan engine, which was a license-built version of the Rolls-Royce Spey. It offered a thrust of 14,500 lbf (64,000 N), over 2,000 lbf (8,900 N) greater than that of the TF30 that powered the Navy's Corsair IIs. Other changes included a head up display, a new avionics package, and an M61A1 rotary cannon in place of the two single-barreled 20-mm cannon. Also included
7367-461: The American Fairchild Republic A-10 Thunderbolt II and the Soviet/Russian Sukhoi Su-25 Frogfoot. A variety of light attack aircraft has also been introduced in the post-World War II era, usually based on adapted trainers or other light fixed-wing aircraft. These have been used in counter-insurgency operations. U.S. attack aircraft are currently identified by the prefix A- , as in " A-6 Intruder " and " A-10 Thunderbolt II ". However, until
7506-428: The Army pressured the Air Force to procure a specialized subsonic close air support fixed-wing aircraft that would suit its needs better than the general-purpose supersonic aircraft that the USAF preferred. The Vought A-7 seemed to be a relatively quick and inexpensive way to satisfy this need. However, the USAF was initially reluctant to take on yet another Navy-designed aircraft, but Secretary of Defense Robert McNamara
7645-432: The BT-9 was the T-6 Texan trainer, of which 17,000 were built, making it the most widely used trainer ever. The twin-engine B-25 Mitchell bomber achieved fame in the Doolittle Raid and was used in all combat theaters of operation. The P-51 Mustang was initially produced for Britain as an alternative to the Curtiss P-40 Warhawk , which North American had declined to produce under licence. The derivative A-36 Mustang
7784-432: The Brazilian Constitutionalist Revolution of 1932 , although both sides had few aircraft. The federal government had approximately 58 aircraft divided between the Navy and the Army , as the Air Force at this time did not constitute an independent branch. In contrast, the rebels had only two Potez 25 planes and two Waco CSO , plus a small number of private aircraft. During the 1930s, Nazi Germany had begun to field
7923-415: The Columbus plant grew from 1,600 in 1950 to 18,000 in 1952. The cancellation of the F-107 and F-108 programs in the late 1950s, as well as the cancellation of the Navaho intercontinental cruise missile program, was a blow to North American from which it never fully recovered.

In 1973, the company changed its name again to Rockwell International and named its aircraft division North American Aircraft Operations. Rockwell International's defense and space divisions (including the North American Aviation divisions Autonetics and Rocketdyne) were sold to Boeing in December 1996. Initially called Boeing North American, these groups were integrated with Boeing's Defense division. Rocketdyne

The A-7's wing was not only larger but had reduced sweepback, as well as six pylons with the carriage of up to 15,000 lb (6,800 kg) of bombs or other equipment. According to Gunston and Gilchirst, there were no common structural features shared between the two aircraft despite their visual similarity and shared heritage. The A-7 had fully powered flight controls, as did

In 1955, the department was renamed Atomics International and engaged principally in the early development of nuclear technology and nuclear reactors for both commercial and government applications. Atomics International was responsible for a number of accomplishments relating to nuclear energy: design, construction and operation of the first nuclear reactor in California (a small aqueous homogeneous reactor located at

However, conventional outboard ailerons were used (instead of the drooping ailerons mounted inboard of the wing-fold of the F-8 and doubling as flaps when flaps were deployed), along with large slotted flaps on the wing's inboard area; the wing fold was between the flaps and ailerons. The wing leading edge was fixed and had a dog-tooth discontinuity. A large air brake was fitted on

#17327801143798618-455: The F-8. The same engine had also powered several other combat aircraft of the era, including the General Dynamics F-111 Aardvark and early Grumman F-14 Tomcats . The TF30-P-6 did not require an afterburner for its subsonic role. Later versions of the A-7 used different engines; according to Gunston and Gilchrist, this was largely due to production difficulties in keeping up with numerous military and civil demands. These new powerplants included
8757-413: The German Focke-Wulf Fw 190 , the British Hawker Typhoon and the US Republic P-47 Thunderbolt . The Typhoon, which was disappointing as a fighter, due to poor high altitude performance, was very fast at low altitudes and thus became the RAF's premier ground attack fighter. It was armed with four 20mm cannon , augmented first with bombs, then rockets. Likewise the P-47 was designed and intended for use as
8896-974: The ILAAS digital navigation system. The radar also fed an IBM navigation and weapons delivery computer which made possible accurate delivery of bombs from a greater stand-off distance, greatly improving survivability compared with faster aircraft such as the McDonnell Douglas F-4 Phantom II . It was the first U.S. aircraft to have a modern head-up display , (made by Marconi - Elliott ), now a standard instrument, which displayed information such as dive angle, airspeed, altitude, drift and aiming reticule. The integrated navigation system also had another innovation—the projected map display system (PMDS) which accurately showed aircraft position on two different map scales. The A-7 had more modern avionics and systems than contemporary aircraft. This included data link capabilities that, among others, provided "hands-off" carrier landing capability when used with its approach power compensator (APC) or auto throttle. Other notable and advanced equipment
9035-409: The LTV production line in Dallas open and the workers employed in the wake of post-Vietnam DOD procurement reductions. As a result of these unplanned acquisitions, the Air Force assigned these new aircraft (all with 1975 tail numbers) to the Arizona Air National Guard 152nd Tactical Fighter Squadron at Tucson, which operated the Air National Guard transition training school for Corsair II pilots.

Rotational deployments began to Korat from the 355th TFW and 23d TFW, with pilots and support personnel beginning six-month deployment cycles. In March 1973, the 354th transferred a squadron of A-7Ds to the 388th TFW, the host wing at Korat RTAFB at the time, which re-established the 3d Tactical Fighter Squadron and created
9313-523: The NAA Downey plant), the first nuclear reactor to produce power for a commercial power grid in the United States (the Sodium Reactor Experiment located at the Santa Susana Field Laboratory ) and the first nuclear reactor launched into outer space by the United States (the SNAP-10A ). As overall interest in nuclear power declined, Atomics International transitioned to non-nuclear energy-related projects such as coal gasification and gradually ceased designing and testing nuclear reactors. Atomics International
9452-408: The Navy's consideration on the matter. In December 1962, the Sea-Based Air Strike Forces (SBASF) study group started examining detailed performance and cost evaluations on the topic. The group analyzed a total of 144 hypothetical aircraft to support their findings. According to Gunston and Gilchrist, a major finding from these studies was that a subsonic aircraft would achieve superior performance to
9591-449: The P-51 into what many consider to be the best American fighter of the war. Labor troubles became a grave issue in 1941. During the 22 months from August 1939 to June 1941 Stalin and Hitler supported each other as war raged in Europe. In the U.S., local union officials opposed American aid to Britain's war against Germany. They called strikes in war industries that were supplying Lend Lease to Britain. The United Auto Workers (UAW) won
9730-428: The Red Sea to targets throughout Iraq. The A-7 was used both day and night to attack a wide range of heavily defended deep interdiction targets in Iraq as well as "kill boxes" (geographically defined kill zones) in Kuwait, employing a variety of weapons including precision-guided munitions (PGMs), such as the TV-guided Walleye glide bomb, unguided general-purpose bombs, and High Speed Anti-Radiation missiles (HARM). The A-7
9869-415: The South Dakota 175th Tactical Fighter Squadron and Ohio 112th Tactical Fighter Squadron were at Howard AFB on a Coronet Cove deployment when President George H. W. Bush announced Operation Just Cause, the United States Invasion of Panama. The ANG squadrons participated in the invasion, flying 34 combat missions, completing 34 sorties, expended 71.7 flying hours and expended 2,715 rounds of ordnance. In
10008-597: The U.S. Marine Corps has noted similar problems. In the late 1960s the United States Air Force requested a dedicated close air support (CAS) plane that became the Fairchild Republic A-10 Thunderbolt II . The A-10 was originally conceived as an anti-armor weapon (the A-X program requirements specifically called for an aircraft mounting a large rotary cannon to destroy massed Warsaw Pact armored forces) with limited secondary capability in
10147-602: The USAAF, preferred the older term "Scout-Bomber", under a "SB-" designation, such as the Curtiss SB2C Helldiver . The Junkers Ju 87s of the German Luftwaffe became virtually synonymous with close air support during the early months of World War II. The British Commonwealth's Desert Air Force , led by Arthur Tedder, became the first Allied tactical formation to emphasize the attack role, usually in
10286-685: The USAAF. It was not until 1946, when the US Navy and US Marine Corps started using the "attack" (A) designation, when it renamed BT2D Skyraider and BTM Mauler to, respectively, AD Skyraider and AM Mauler. As with many aircraft classifications, the definition of attack aircraft is somewhat vague and has tended to change over time. Current U.S. military doctrine defines it as an aircraft which most likely performs an attack mission , more than any other kind of mission. Attack mission means, in turn, specifically tactical air-to-ground action—in other words, neither air-to-air action nor strategic bombing
10425-640: The USAF to the National Guard Bureau for subsequent re-allocation. By 1981, when the 23d TFW sent its last A-7Ds to Tonopah Test Range Airport , Nevada for clandestine use in the Lockheed F-117 Nighthawk development program, fifteen ANG squadrons were equipped with the A-7D Corsair II. However, Congressional decisions added additional funding to the DOD FY 1975 and FY 1976 budgets for the procurement of additional A-7Ds, primarily to keep
10564-521: The USSR on June 22, the Communist activists suddenly became the strongest supporters of war production; they crushed wildcat strikes. Post-war, North American's employment dropped from a high of 91,000 to 5,000 in 1946. On V-J Day , North American had orders from the U.S. government for 8,000 aircraft. A few months later, that had dropped to 24. Two years later in 1948, General Motors divested NAA as
10703-408: The United States where they were reassigned to several Air National Guard squadrons. With the end of the Vietnam War, the Air Force began to transfer its active duty A-7D aircraft to Air National Guard units beginning in 1974. The Corsairs had been, in a sense, a forced acquisition by the USAF in the late 1960s, and the inter-service rivalry of flying a Navy aircraft had led, beginning about 1970, to
10842-492: The United States, the most produced postwar military aircraft in the West, as well as another 2,500 elsewhere. To accommodate its Sabre production, North American opened facilities in a former Curtiss-Wright plant in Columbus, Ohio . It also moved into a former Consolidated-Vultee Aircraft plant at Downey, California , and in 1948, built a new plant at Downey. By the end of 1952, North American sales topped $ 315 million. Employment at
10981-529: The Vietnam War, the recovery of SS Mayagüez after it was hijacked by Khmer Rouge gunboats. A total of 98 USN A-7 Corsairs were lost during the war. With the pullout of the USAF from its Thailand bases in late 1975, the A-7Ds stationed at Korat initially went to Clark AB , Philippines . The 3d TFS transitioned from its Corsairs to the F-4E Phantom II and remained at Clark. The A-7Ds were returned to
11120-449: The bombload of an A-4E, or the same payload over twice its maximum distance. The flight test program proceeded at a relatively rapid pace, during which no major setbacks were uncovered or meaningful delays were incurred. According to Gunston and Gilchrist, there were some naval officials that sought to slow the program down so that the A-7's avionics systems could be revised for greater capabilities, but this preference had been overridden by
11259-567: The boom receptacle being on the top of the fuselage behind the cockpit and offset to port. The Navy was sufficiently impressed with the increased power offered by the A-7D Spey engine used by the Air Force, and decided to use this engine for its own version of the Corsair II. The designation A-7E was assigned, and this version was to succeed the A-7B in production. However, there were delays in
11398-639: The breakup of such holding companies. North American became a manufacturing company, run by James H. "Dutch" Kindelberger , who had been recruited from Douglas Aircraft Company . NAA did retain ownership of Eastern Air Lines until 1938. In 1933, the General Motors Corporation purchased a controlling interest in NAA, and merged it with the General Aviation Manufacturing Corporation , but retained
11537-407: The broad concept of an attack aircraft. The dedicated attack aircraft as a separate class existed primarily during and after World War II . The precise implementation varied from country to country, and was handled by a wide variety of designs. In the United States and Britain , attack aircraft were generally light bombers or medium bombers , sometimes carrying heavier forward-firing weapons like
11676-666: The current U.S. designation system, an attack aircraft ( A ) is designed primarily for air-to-surface (Attack: Aircraft designed to find, attack, and destroy land or sea targets) missions (also known as "attack missions"), while a fighter category F incorporates not only aircraft designed primarily for air-to-air combat , but additionally multipurpose aircraft designed also for ground-attack missions. "F" - Fighter Aircraft were designed to intercept and destroy other aircraft or missiles. This includes multipurpose aircraft also designed for ground support missions such as interdiction and close air support. Just to mention one example amongst many,
11815-676: The deliveries of the TF41-A-2 engine specified for the A-7E, so the first 67 aircraft of the order were delivered with the TF30-P-8 engine. These aircraft had all of the other improvements planned for the A-7E, including the improved avionics and the M61 rotary cannon, and were re-designated A-7C after delivery. During 1967, the Navy decided to cancel its order for the A-7B, resulting in 257 aircraft less of this variant being constructed. Taking its place,
11954-462: The development of its own Close Air Support aircraft. In 1974, selection of the Fairchild Republic A-10 Thunderbolt II was made as the replacement for the A-7D. The first A-10As were received by the 354th TFW in 1977 at Myrtle Beach AFB; the 355th TFW at Davis-Monthan AFB began replacing its A-7Ds in 1978, and the 23d TFW at England AFB in 1979. As the A-10s were received, the A-7Ds were transferred from
12093-603: The election over the International Association of Machinists and represented all the employees at the North American factory in Inglewood, California. UAW negotiators demanded the starting pay be raised from 50 cents an hour to 75 cents, plus a 10 cents raise for the 11,000 current employees. The national union had made a no-strike pledge but suddenly a wildcat strike by the local on June 5 closed
12232-458: The end of World War II the A- designation was shared between attack planes and light bombers for USAAF aircraft (as opposed to B- prefix for medium or heavy bombers). The US Navy used a separate designation system and at the time preferred to call similar aircraft scout bombers (SB) or torpedo bombers (TB or BT). For example, Douglas SBD Dauntless scout bomber was designated A-24 when used by
12371-690: The exclusive development and production of the A-5 Vigilante , an advanced high speed attack aircraft that saw significant use as a naval reconnaissance aircraft during the Vietnam War , the OV-10 Bronco , the first aircraft specifically designed for forward air control (FAC), and counter-insurgency (COIN) duties, and the T-2 Buckeye Naval trainer, which would serve from the late 1950s until 2008 and be flown in training by virtually every Naval Aviator and Naval Flight Officer in
12510-549: The first AGM-88 HARM missiles ever used in combat. On the next day, A-6s attacked Libyan warships approaching the US fleet, while A-7s again launched HARM missiles against Libyan SAM sites. In April 1986, navy Sixth Fleet A-7Es from VA-72 and VA-46 embarked on board USS America also participated in Operation El Dorado Canyon , the retaliatory attack on Libya, using HARM and Shrike anti-radar missiles to protect
12649-400: The first A-7A performed the type's maiden flight . On 2 November 1965, Vought publicly demonstrated the first pair of A-7As to 1,000 guests; test pilot John Conrad demonstrated the aircraft's ability to perform rapid rolls even while laden with a payload of six 250 lb (110 kg) and twelve 500 lb (230 kg) bombs. A Navy spokesperson acknowledged the A-7's ability to carry double
12788-451: The flaps to be slowly raised by several degrees per tap of the flap handle as airspeed slowly increased during max-weight takeoffs.) Carrier catapult launches at maximum weight under these performance-robbing conditions were not significantly better and were characterized by the aircraft decelerating by as much as 20 knots (37 km/h) immediately after launch. As a result, A-7A units operated their aircraft 4,000 pounds (1,800 kg) below
12927-614: The form of single-engine Hawker Hurricane and Curtiss P-40 fighter-bombers or specialized "tank-busters", such as the Hurricane Mk IID, armed with two 40 mm Vickers S guns (notably No. 6 Squadron RAF ). At around the same time, a massive invasion by Axis forces had forced the Soviet air forces to quickly expand their army support capacity, such as the Ilyushin Il-2 Sturmovik. The women pilots known as
13066-466: The fuselage. Later variants had the two cannons replaced with a single M61A1 Vulcan rotary cannon, along with other improvements. To reduce vulnerability to ground fire the flying control hydraulic systems were triplicated, other systems duplicated and much of the fuselage had armor protection. The A-7 was fitted with an AN/APQ-116 radar, later followed by the AN/APQ-126, which was integrated into
13205-485: The jets as they were able to both out accelerate and out maneuver the jets. The Royal Navy Hawker Sea Fury fighters and the U.S. Vought F4U Corsair and Douglas A-1 Skyraider were operated during the Korean War while the latter continued to be used throughout the Vietnam War . Many post-World War II era air forces have been reluctant to adopt fixed-wing jet aircraft developed specifically for ground attack. Although close air support and interdiction remain crucial to
13344-487: The leading Stuka ace, Hans-Ulrich Rudel , who claimed 500 tanks, a battleship, a cruiser, and two destroyers in 2,300 combat missions. The Bristol Beaufighter , based on an obsolescent RAF bomber, became a versatile twin-engine attack aircraft and served in almost every theatre of the war, in the maritime strike and ground attack roles as well as that of night fighter. Conversely, some mid-war attack types emerged as adaptations of fighters, including several versions of
13483-477: The mining of Haiphong harbor in 1972, and played a vital role in Operations Linebacker I and Linebacker II that led up to the formal end of US involvement in the Vietnam War on 24 January 1973. On 15 May 1975, A-7E aircraft operating from USS Coral Sea , in conjunction with A-7D aircraft assigned to the 3d TFS at Korat RTAFB, provided air cover in what is considered the last battle of
13622-462: The modern battlefield, attack aircraft are less glamorous than fighters, while air force pilots and military planners have a certain well-cultivated contempt for "mud-movers". More practically, the cost of operating a specialized ground-attack aircraft is harder to justify when compared with multirole combat aircraft . Jet attack aircraft were designed and employed during the Cold War era, such as
13761-561: The more powerful Pratt & Whitney TF30-8 and the Allison TF41-A-2 engines, a licensed model of the Rolls-Royce Spey engine. The TF41 corrected issues that had troubled initial A-7 operations, such as severe compressor stalls and low thrust. The Air Force A-7D had self-contained starting using internal batteries and a gas turbine starter. The Navy A-7E used an air turbine starter driven by an external air supply. Air
13900-574: The most notable attack type to emerge during the late 1930s was the Soviet Ilyushin Il-2 Sturmovik , which became the most-produced military aircraft type in history. As World War II approached, the concept of an attack aircraft was not well defined, and various air services used many different names for widely differing types, all performing similar roles (sometimes in tandem with non-attack roles of bombers, fighters, reconnaissance and other roles. The British concept of
14039-464: The much more advanced A-7E model. Six Naval Reserve attack squadrons would also eventually transition to the A-7, operating from NAS Cecil Field, Florida; NAS Atlanta/ Dobbins ARB , Georgia; NAS New Orleans , Louisiana; NAS Alameda , California and NAS Point Mugu , California. An additional active duty squadron stood up in the 1980s, Tactical Electronic Warfare Squadron 34 ( VAQ-34 ) at NAS Point Mugu, operating twin-seat TA-7C and EA-7L aircraft with both
14178-441: The munitions costs per target. On 17 May 1963, these criteria were formulated into a draft requirement, known as VAL (Heavier-than-air, Attack, Light). On 29 May 1963, the request for proposals (RFP) associated with the requirement was issued. To minimize costs, all proposals had to be based on existing designs. Accordingly, Vought , Douglas Aircraft , Grumman and North American Aviation chose to respond. The Vought proposal
14317-460: The name North American Aviation. Kindelberger moved the company's operations from Dundalk, Maryland to Los Angeles, California , which allowed flying year-round, and decided to focus on training aircraft, on the theory that it would be easier than trying to compete with established companies on larger projects. NAA's first planes were the GA-15 observation plane and the GA-16 trainer, followed by
14456-526: The naval strike force from SAMs. While USAF A-7s stayed home in favor of A-10s, the USN deployed two of its last A-7E squadrons to Operation Desert Shield in August 1990 aboard USS John F. Kennedy , the only carrier of six deployed to Desert Storm to operate the A-7. The navy squadrons VA-46 and VA-72 made the last combat sorties of the A-7 in Operation Desert Storm flying from
14595-643: The plant that produced a fourth of the fighters. The UAW national leader Richard Frankensteen flew in but was unable to get the workers to return. So Washington intervened. With the approval of national CIO leadership, President Franklin Roosevelt on June 8 sent in the California national guard to reopen the plant with bayonets. Strikers were told to return immediately or be drafted into the US Army. They sullenly complied. However, when Germany suddenly invaded
14734-598: The post-Vietnam era, the Air National Guard frequently deployed its Corsairs on annual operational exercises. Deployments were made to NATO and USAFE bases in West Germany and Denmark as part of training exercises along with the USAREUR Reforger training exercises. Beginning in 1974, active-duty squadrons from Myrtle Beach, England and Davis-Monthan Air Force Bases began deployments of A-7Ds to Howard AFB, Panama to train with Army and Naval forces defending
14873-518: The post-World War II era has also expanded need for these types of aircraft to conduct counter-insurgency and light ground attack operations. A primary distinction of post-World War II aviation between the U.S. Army and the U.S. Air Force was that latter had generally been allocated all fixed-wing aircraft , while helicopters were under control of the former; this was governed by the 1948 Key West Agreement . The Army, wishing to have its own resources to support its troops in combat and faced with
15012-512: The prospect of a rocket attack was unnerving. The ultimate development of the cannon-armed light attack aircraft was the small production run in 1944 of the Henschel Hs 129 B-3, armed with a modified PAK 40 75 mm anti-tank gun. This weapon, the Bordkanone BK 7,5 , was the most powerful forward-firing weapon fitted to a production military aircraft during World War II. The only other aircraft to be factory-equipped with similar guns were
15151-529: The rated maximum takeoff weight for the A-7E. In a sortie against the Thanh Hóa Bridge on 6 October 1972, four A-7Cs from VA-82 successfully delivered 8,000 lb of high explosives with two aircraft carrying two 2,000 lb (910 kg) Walleyes , while two others also carried 2,000 lb in Mk 84 GP bombs . In a simultaneous attack, the center piling on the bridge's west side was hit and broke
15290-621: The rescue, Clarke was awarded the Air Force Cross , the USAF's second-highest decoration for valor, and his A-7D (AF Serial No. 70-0970 ) was eventually placed on display on 31 January 1992 at the National Museum of the United States Air Force at Wright-Patterson AFB , Ohio. With the end of US involvement in South Vietnam, the 354th TFW, deployed at Korat, began flying combat sorties in Cambodia to support
15429-663: The span in half. After this, the Thanh Hoa bridge was considered permanently destroyed and removed from the target list. The Spey-powered A-7E entered service in Southeast Asia in May 1970 with VA-146 and VA-147 deployed aboard USS America . The A-7E participated in numerous close-air support missions over both North and South Vietnam, with its state-of-the-art bombing and navigation system being particularly reliable and accurate. Most air wings operating A-4 Skyhawks and early A-7s were re-equipped with A-7Es. The A-7E participated in
15568-509: The specification was dropped before an aircraft went into production. In some air services, dive bombers did not equip ground-attack units, but were treated as a separate class. In Nazi Germany, the Luftwaffe distinguished between the Stuka ( Sturzkampf- , "dive bombing") units, equipped with Junkers Ju 87 from Schlacht ("battle") units, using strafing/low-level bombing types such as
15707-609: The time. Navy A-7E squadrons VA-15 and VA-87 , from USS Independence , provided close air support during the Invasion of Grenada , codenamed Operation Urgent Fury, in October 1983. Navy A-7s also provided air support during the U.S. mission in Lebanon in 1983. An A-7 and an A-6 Intruder were shot down by Syrian surface-to-air missiles (SAM) on 4 December 1983. The A-7 pilot, Commander Edward Andrews, managed to guide his failing Corsair over coastal waters before ejecting; he
15846-463: The underside of the aircraft. The three-unit landing gear retracted into the fuselage; the twin-wheel nose gear was steerable and stressed for catapult-assisted take-offs . To achieve the required range, initial versions of the A-7 were powered by a single Pratt & Whitney TF30-P-6 turbofan engine, which produced 11,350 lbf (50.5 kN) of thrust. It had replaced the afterburner -equipped Pratt & Whitney J57 -P-20A turbojet engine of
15985-651: The war with only six losses—the lowest of any U.S. fighter in the theater. The aircraft was second only to Boeing B-52 Stratofortress in the amount of ordnance dropped on Hanoi and dropped more bombs per sortie with greater accuracy than any other U.S. attack aircraft. In Vietnam, the hot, humid air robbed all jet engines of power, and even the upgraded A-7D and A-7E fell short of their required power levels when serving in these conditions. Takeoff rolls were lengthy, and fully armed aircraft struggled to reach 500 mph (800 km/h). For A-7A aircraft, high-density altitude and maximum-weight runway takeoffs often necessitated
16124-452: Was a computerized navigation/weapons delivery system with AN/APQ-126 radar and a head-up display. Two YA-7D prototypes were completed with TF30-P-6 engines, and the first of these flew on 6 April 1968. The first Spey-powered A-7D ( 67-14854 ) flew for the first time on 26 September 1968. The seventeenth production aircraft introduced a provision for boom flight refueling in place of the Navy's retractable starboard-side probe/drogue system, with
16263-753: Was a major American aerospace manufacturer that designed and built several notable aircraft and spacecraft. Its products included the T-6 Texan trainer, the P-51 Mustang fighter , the B-25 Mitchell bomber , the F-86 Sabre jet fighter, the X-15 rocket plane , the XB-70 bomber, the B-1 Lancer , the Apollo command and service module , the second stage of the Saturn V rocket , and
16402-621: Was a part of the Allied armies' strength in holding German attacks and supporting Allied counter-attacks and offensives. Admittedly, the cost to the Allies was high, with the Royal Flying Corps sustaining a loss rate approaching 30% among ground-attack aircraft. After World War I, it was widely believed that using aircraft against tactical targets was of little use other than in harassing and undermining enemy morale; attacking combatants
16541-401: Was a projected map display located just below the radar scope. The map display was slaved to the inertial navigation system and provided a high-resolution map image of the aircraft's position superimposed over TPC/JNC charts. Moreover, when slaved to the all-axis auto pilot, the inertial navigation system could fly the aircraft "hands off" to up to nine individual waypoints. Typical inertial drift
16680-425: Was also used as a tanker in numerous in-flight refueling missions. Attack aircraft Fighter aircraft often carry out the attack role, although they would not be considered attack aircraft per se ; fighter-bomber conversions of those same aircraft would be considered part of the class. Strike fighters , which have effectively replaced the fighter-bomber and light bomber concepts, also differ little from
16819-499: Was an armored twin-engine triplane for ground strafing with eight machine guns and about a ton of armor plate, and the 1922 Aeromarine PG-1 was a combined pursuit (fighter) and ground attack design with a 37mm gun. The United States Marine Corps Aviation applied close air support tactics in the Banana Wars . While they did not pioneer dive bombing tactics, Marine aviators were the first to include it in their doctrine during
16958-484: Was approximately 30 pounds per minute (14 kg/min) compared to over 100 pounds per minute (45 kg/min) for the Phantom F-4J/N series. The A-7 Corsair II was tagged with the nickname "SLUF" (" S hort L ittle U gly F ucker") by pilots. The A-7D first entered service in 1970 with the 57th Fighter Weapons Wing at Luke AFB Arizona, and the 354th Tactical Fighter Wing at Myrtle Beach AFB , South Carolina
17097-443: Was based on their successful F-8 Crusader fighter and sharing a similar configuration; however, it had a shorter airframe with a rounded nose, giving the aircraft a "stubbier" appearance. All bids were received by September 1963 and the evaluation process was completed in early November of that year. On 8 February 1964, funding for VAL was approved by Congress , enabling the programme to proceed; three days later, Vought's submission
17236-680: Was developed as a ground attack aircraft and dive bomber. This was done, in part, to keep the airframe in production as the US Army Air Corps had not yet decided to purchase the type as a fighter. A suggestion by the RAF that North American switch the P-51's powerplant from its original Allison engine to the Rolls-Royce Merlin engine may have been one of the most significant events in World War II aviation, as it transformed
17375-628: Was equipped with four squadrons of A-7Ds by 1972; the 355th TFW at Davis-Monthan AFB was equipped with four squadrons in 1972, and in 1973, the 23d TFW at England AFB, Louisiana was fully equipped with A-7Ds. The 354th TFW first deployed two squadrons of A-7Ds to Korat Royal Thai AFB , Thailand in September 1972 as part of Operation Cornet Dancer, The A-7Ds were quickly assigned the "Sandy mission" of providing air cover for Combat Search and Rescue missions of downed pilots. Taking over from Douglas A-1 Skyraiders (and adopting their call sign of "Sandy"),
17514-759: Was eventually merged with the Rocketdyne division in 1978. Autonetics began in 1945 at North American's Technical Research Laboratory, a small unit in the Los Angeles Division's engineering department based in Downey, California . The evolution of the Navaho missile program resulted in the establishment of Autonetics as a separate division of North American Aviation in 1955, first located in Downey, later moving to Anaheim, California in 1963. The division
17653-475: Was expected and operating at low altitudes to precisely identify targets. Other roles, including those of light bombers , medium bombers , dive bombers , reconnaissance , fighters , fighter-bombers , could and did perform air strikes on battlefields. All these types could significantly damage ground targets from a low level flight, either by bombing, machine guns, or both. Attack aircraft came to diverge from bombers and fighters. While bombers could be used on
17792-445: Was fed to the engine through ducting from a simple nose inlet, similar to that on the F-8, despite the potential hazard it posed to flight deck personnel. An aerial refueling probe was mounted on the righthand side of the nose. Two cannons were installed on the underside of the nose. For self-defense against aerial threats, the A-7, in addition to the cannons, had a mounting for AIM-9 Sidewinder air-to-air missiles on either side of
17931-641: Was generally much more dangerous to aircrews than their targets, a problem that was continually becoming more acute with the ongoing refinement of anti-aircraft weapons . Within the range of types serving attack roles, dive bombers were increasingly being seen as more effective than aircraft designed for strafing with machine guns or cannons . Nevertheless, during the 1920s, the US military, in particular, procured specialized "Attack" aircraft and formed dedicated units, that were trained primarily for that role. The US Army Engineering Division became involved in designing ground attack aircraft. The 1920 Boeing GA-1
18070-558: Was insistent. On 5 November 1965, Secretary of the Air Force Harold Brown and USAF Chief of Staff General John P. McConnell announced that they had decided to order a version of the Corsair II, designated A-7D, for the Tactical Air Command . The A-7D differed from the Navy's Corsair II in several ways. For one, the USAF insisted on significantly more power for its Corsair II version, and it selected
18209-516: Was involved in the development of guidance systems for the Minuteman ballistic missile system. In 1955, the rocket engine operations were spun off into a separate division as Rocketdyne . This division furnished engines for the Redstone , Jupiter , Thor , Delta , and Atlas missiles, and for NASA 's Saturn family of launch vehicles . North American designed and built the airframe for
18348-658: Was largely replaced by newer generation fighters such as the General Dynamics F-16 Fighting Falcon and the McDonnell Douglas F/A-18 Hornet . The final operator, the Hellenic Air Force , withdrew the last A-7s during 2014. In 1960, officials within the United States Navy (USN) began to consider the need to replace its existing fleet of Douglas A-4 Skyhawk , a light attack aircraft. At that time, it
18487-495: Was minimal for newly manufactured models and the inertial measurement system accepted flyover, radar, and TACAN updates. Initial operational basing/homeporting for USN A-7 squadrons was at NAS Cecil Field , Florida for Atlantic Fleet units and NAS Lemoore , California for Pacific Fleet units. This was in keeping with the role of these bases in already hosting the A-4 Skyhawk attack squadrons that would eventually transition to
18626-503: Was not clear that the A-4 would eventually remain in production until 1979; furthermore, according to aviation authors Bill Gunston and Peter Gilchrist, some figures believed there to be an unmet requirement for a more capable attack platform that could routinely attain supersonic speeds, carry heavier payloads, and fly further than its predecessors. Proponents of a new attack aircraft included Secretary of Defense Robert McNamara , who urged
18765-585: Was replaced by faster fighter types for photo-reconnaissance, and light aircraft for artillery spotting. During the inter-war period, the British flew the Fairey Battle , a light bomber which originated in a 1932 specification. Designs in 1938 for a replacement were adapted as a target tug. The last British specification issued for a light bomber was B.20/40 described as a "Close Army Support Bomber" capable of dive bombing and photo-reconnaissance. However,
18904-480: Was rescued by a Lebanese fishing boat and safely returned to the U.S. Marines. On 24 March 1986, during the Gulf of Sidra dispute with Libya, Libyan air defense operators launched SA-5 missiles at two Fighter Squadron 102 ( VF-102 ) Grumman F-14 Tomcats from USS America that were orbiting in international air space on a Combat Air Patrol (CAP) station. A-7s operating from USS Saratoga responded by launching
19043-477: Was selected as the winner. On 19 March 1964, Vought received a contract from the Navy for the manufacture of the initial batch of aircraft, designated A-7 . On 22 June 1964, the mock-up review took place. In 1965, the A-7 received the name Corsair II ; Vought had previously produced three aircraft known as "Corsair". During the 1920s, they had produced the O2U Corsair biplane scout and observation aircraft and
19182-780: Was the Junkers J.I , which pioneered the idea of an armored "bathtub", that was both fuselage structure and protection for engine and crew. The British experimented with the Sopwith TF series (termed "trench fighters"), although these did not see combat. The last battles of 1918 on the Western Front demonstrated that ground-attacking aircraft were a valuable component of all-arms tactics. Close support ground strafing ( machine-gunning ) and tactical bombing of infantry (especially when moving between trenches and along roads), machine gun posts , artillery , and supply formations
19321-586: Was to create a safe corridor through the Iraqi air defense system. The attack was a huge success and cleared the way for the beginning of the Allied bombing campaign of Operation Desert Storm . One concern involving the Apache arose when a unit of these helicopters was very slow to deploy during U.S. military involvement in Kosovo. According to the Army Times , the Army is shifting its doctrine to favor ground-attack aircraft over attack helicopters for deep strike attack missions because ground-attack helicopters have proved to be highly vulnerable to small-arms fire;
