133-721: Joint Strike Fighter ( JSF ) is a development and acquisition program intended to replace a wide range of existing fighter , strike , and ground attack aircraft for the United States, the United Kingdom, Italy, Canada, Australia, the Netherlands, Denmark, Norway, and formerly Turkey. After a competition between the Boeing X-32 and the Lockheed Martin X-35 , the latter aircraft was selected for
266-705: A Mikoyan-Gurevich MiG-15 in Korea, although by this time the F-80 (as it was redesignated in June 1948) was already considered obsolete. Starting with the P-80, Lockheed's secret development work was conducted by its Advanced Development Division, more commonly known as the Skunk works . The name was taken from Al Capp 's comic strip Li'l Abner . This organization has become famous and spawned many successful Lockheed designs, including
399-584: A by now mediocre performance. The first Eindecker victory came on 1 July 1915, when Leutnant Kurt Wintgens , of Feldflieger Abteilung 6 on the Western Front, downed a Morane-Saulnier Type L. His was one of five Fokker M.5 K/MG prototypes for the Eindecker , and was armed with a synchronized aviation version of the Parabellum MG14 machine gun. The success of the Eindecker kicked off
532-406: A cadre of exceptional pilots. In the United Kingdom, at the behest of Neville Chamberlain (more famous for his 'peace in our time' speech), the entire British aviation industry was retooled, allowing it to change quickly from fabric covered metal framed biplanes to cantilever stressed skin monoplanes in time for the war with Germany, a process that France attempted to emulate, but too late to counter
665-435: A competitive cycle of improvement among the combatants, both sides striving to build ever more capable single-seat fighters. The Albatros D.I and Sopwith Pup of 1916 set the classic pattern followed by fighters for about twenty years. Most were biplanes and only rarely monoplanes or triplanes . The strong box structure of the biplane provided a rigid wing that allowed the accurate control essential for dogfighting. They had
798-531: A contract award and developed into the F-35 Lightning II , which will replace various tactical aircraft, including the US F-16 , A-10 , F/A-18A-D , AV-8B , EA-6B and British Harrier GR7, GR9s and Tornado GR4 . The projected average annual cost of the program is $ 12.5 billion in 2012 with an estimated cost in 2024 of $ 2 trillion over its lifespan. The JSF program was the result of the merger of
931-443: A difficult deflection shot. The first step in finding a real solution was to mount the weapon on the aircraft, but the propeller remained a problem since the best direction to shoot is straight ahead. Numerous solutions were tried. A second crew member behind the pilot could aim and fire a swivel-mounted machine gun at enemy airplanes; however, this limited the area of coverage chiefly to the rear hemisphere, and effective coordination of
1064-552: A form that would replace all others in the 1930s. As collective combat experience grew, the more successful pilots such as Oswald Boelcke , Max Immelmann , and Edward Mannock developed innovative tactical formations and maneuvers to enhance their air units' combat effectiveness. Allied and – before 1918 – German pilots of World War I were not equipped with parachutes , so in-flight fires or structural failures were often fatal. Parachutes were well-developed by 1918 having previously been used by balloonists, and were adopted by
1197-560: A formal partner, and agreed to pay $ 200 million, or 10% of the concept demonstration phase. In 1997, Canada 's Department of National Defence signed on to the Concept Demonstration phase with an investment of US$ 10 million. This investment allowed Canada to participate in the extensive and rigorous competitive process where Boeing and Lockheed Martin developed and competed their prototype aircraft. Studies supporting JAST/JSF started in 1993 and led to STOVL submissions to
1330-664: A great deal of ground-attack work. In World War II, the USAAF and RAF often favored fighters over dedicated light bombers or dive bombers , and types such as the Republic P-47 Thunderbolt and Hawker Hurricane that were no longer competitive as aerial combat fighters were relegated to ground attack. Several aircraft, such as the F-111 and F-117, have received fighter designations though they had no fighter capability due to political or other reasons. The F-111B variant
1463-508: A leafy texture. Lockheed ranked tenth among United States corporations in the value of wartime production contracts. All told, Lockheed and its subsidiary Vega produced 19,278 aircraft during World War II, representing six percent of war production, including 2,600 Venturas , 2,750 Boeing B-17 Flying Fortress bombers (built under license from Boeing ), 2,900 Hudson bombers, and 9,000 Lightnings. During World War II, Lockheed, in cooperation with Trans-World Airlines (TWA), had developed

#17327825331891596-431: A number of twin-engine fighters were built; however they were found to be outmatched against single-engine fighters and were relegated to other tasks, such as night fighters equipped with radar sets. By the end of the war, turbojet engines were replacing piston engines as the means of propulsion, further increasing aircraft speed. Since the weight of the turbojet engine was far less than a piston engine, having two engines
1729-550: A part of military nomenclature, a letter is often assigned to various types of aircraft to indicate their use, along with a number to indicate the specific aircraft. The letters used to designate a fighter differ in various countries. In the English-speaking world, "F" is often now used to indicate a fighter (e.g. Lockheed Martin F-35 Lightning II or Supermarine Spitfire F.22 ), though "P" used to be used in
1862-643: A prototype for the civil market, but folded in 1920 due to the flood of surplus aircraft deflating the market after World War I . Allan went into the real estate market while Malcolm had meanwhile formed a successful company marketing brake systems for automobiles. On December 13, 1926, Allan Loughead, John Northrop , Kenneth Kay and Fred Keeler secured funding to form the Lockheed Aircraft Company ( spelled phonetically to prevent mispronunciation) in Hollywood. This new company used some of
1995-638: A range of specialized aircraft types. Some of the most expensive fighters such as the US Grumman F-14 Tomcat , McDonnell Douglas F-15 Eagle , Lockheed Martin F-22 Raptor and Russian Sukhoi Su-27 were employed as all-weather interceptors as well as air superiority fighter aircraft, while commonly developing air-to-ground roles late in their careers. An interceptor is generally an aircraft intended to target (or intercept) bombers and so often trades maneuverability for climb rate. As
2128-524: A report by auditing firm KPMG that showed that Canada's purchase would cost C$ 45bn over 42 years. Rona Ambrose , Canada's public works minister said: “We have hit the reset button and are taking the time to do a complete assessment of all available aircraft.” Defence Minister Peter MacKay announced Canada's plan to buy the F-35 in 2010 saying that the purchase price was $ 9 billion, but did not provide operating cost estimates. During an election campaign in 2011,
2261-520: A result of these media reports, then Australian defence minister Joel Fitzgibbon requested a formal briefing from the Australian Department of Defence on the simulation. This briefing stated that the reports of the simulation were inaccurate and that it did not compare the F-35's performance against that of other aircraft. Andrew Hoehn, Director of RAND Project Air Force, made the following statement: "Recently, articles have appeared in
2394-742: A result, during the early months of these campaigns, Axis air forces destroyed large numbers of Red Air Force aircraft on the ground and in one-sided dogfights. In the later stages on the Eastern Front, Soviet training and leadership improved, as did their equipment. By 1942 Soviet designs such as the Yakovlev Yak-9 and Lavochkin La-5 had performance comparable to the German Bf 109 and Focke-Wulf Fw 190 . Also, significant numbers of British, and later U.S., fighter aircraft were supplied to aid
2527-643: A separate (and vulnerable) radiator, but had increased drag. Inline engines often had a better power-to-weight ratio . Some air forces experimented with " heavy fighters " (called "destroyers" by the Germans). These were larger, usually twin-engined aircraft, sometimes adaptations of light or medium bomber types. Such designs typically had greater internal fuel capacity (thus longer range) and heavier armament than their single-engine counterparts. In combat, they proved vulnerable to more agile single-engine fighters. The primary driver of fighter innovation, right up to
2660-554: A single family of aircraft; the majority of those produced would replace F-16s. Merrill McPeak , former Chief of Staff of the United States Air Force, has complained that Defense Secretary Les Aspin 's decision to force all three services to use a single airframe greatly increased the costs and difficulty of the project. In November 1995, the United Kingdom signed a memorandum of understanding to become
2793-420: A single operator, who flew the aircraft and also controlled its armament. They were armed with one or two Maxim or Vickers machine guns, which were easier to synchronize than other types, firing through the propeller arc. Gun breeches were in front of the pilot, with obvious implications in case of accidents, but jams could be cleared in flight, while aiming was simplified. The use of metal aircraft structures

His board nominations included former Texas Senator John Tower , the onetime chairman of the Armed Services Committee , and Admiral Elmo Zumwalt Jr ., a former Chief of Naval Operations. Simmons had first begun accumulating Lockheed stock in early 1989 when deep Pentagon cuts to the defense budget had driven down prices of military contractor stocks, and analysts had not believed he would attempt

Bombers are vulnerable due to their low speed, large size and poor maneuvrability. The escort fighter was developed during World War II to come between
3192-549: Is able to defend itself while conducting attack sorties. The word "fighter" was first used to describe a two-seat aircraft carrying a machine gun (mounted on a pedestal) and its operator as well as the pilot . Although the term was coined in the United Kingdom, the first examples were the French Voisin pushers beginning in 1910, and a Voisin III would be the first to shoot down another aircraft, on 5 October 1914. However at
3325-623: Is known as an interceptor . Recognized classes of fighter include: Of these, the Fighter-bomber , reconnaissance fighter and strike fighter classes are dual-role, possessing qualities of the fighter alongside some other battlefield role. Some fighter designs may be developed in variants performing other roles entirely, such as ground attack or unarmed reconnaissance . This may be for political or national security reasons, for advertising purposes, or other reasons. The Sopwith Camel and other "fighting scouts" of World War I performed
3458-562: The Combined Bomber Offensive . Unescorted Consolidated B-24 Liberators and Boeing B-17 Flying Fortress bombers, however, proved unable to fend off German interceptors (primarily Bf 109s and Fw 190s). With the later arrival of long range fighters, particularly the North American P-51 Mustang , American fighters were able to escort far into Germany on daylight raids and by ranging ahead attrited

The merged project continued under the JAST name until the engineering, manufacturing and development (EMD) phase, during which the project became the Joint Strike Fighter. The CALF was a DARPA program to develop a STOVL strike fighter (SSF), originally under the Advanced Short Takeoff and Vertical Landing (ASTOVL) project, for

Rickover condemned the bill saying it represented "a new philosophy where we privatize profits and socialize losses." The New York Times editorial board held that the Nixon administration was violating its own free enterprise principles by advocating for
3857-828: The Future Carrier Borne Aircraft project. This program sought a replacement for the Sea Harrier (and later the Harrier GR7 ); the Joint Strike Fighter was selected in January 2001. During concept definition, two Lockheed Martin airplanes were flight-tested: the X-35A (which was later converted into the X-35B), and the larger-winged X-35C. Arguably the most persuasive demonstration of the X-35's capability
3990-540: The Imperial Japanese Army . At the beginning of World War II, Lockheed – under the guidance of Clarence (Kelly) Johnson , who is considered one of the best-known American aircraft designers – answered a specification for an interceptor by submitting the P-38 Lightning fighter aircraft, a twin-engined, twin-boom design. The P-38 was the only American fighter aircraft in production throughout

Axis fighter aircraft focused on defending against Allied bombers while Allied fighters' main role was as bomber escorts. The RAF raided German cities at night, and both sides developed radar-equipped night fighters for these battles. The Americans, in contrast, flew daylight bombing raids into Germany delivering

The French and the Germans didn't have an equivalent as they used two seaters for reconnaissance, such as the Morane-Saulnier L , but would later modify pre-war racing aircraft into armed single seaters. It was quickly found that these were of little use since the pilot couldn't record what he saw while also flying, while military leaders usually ignored what

The United States Air Force passed over the F-16 Agile Falcon in the late 1980s, essentially an enlarged F-16, and continued to mull other designs. In 1992, the Marine Corps and Air Force agreed to jointly develop the Common Affordable Lightweight Fighter, which continued development efforts under ASTOVL. CALF project

5187-545: The "Lockheed Loan". Even after its adoption, a further controversy developed when the Emergency Loan Guarantee Board set up by the Executive branch to oversee the loan refused to allow Congress' General Accounting Office to examine its records. They argued that the office was attempting "interference in the decision-making process" amounting to an effort to "bully" and "harass" the board. This claim
5320-603: The 1970s. Drowning in debt, in 1971 Lockheed (then the largest US defense contractor) asked the US government for a loan guarantee, to avoid insolvency. Lockheed argued that a government bailout was necessary due to the company's value for U.S. national security. On May 13, 1971, the Richard Nixon administration sent a bill titled "The Emergency Loan Guarantee Act" to Congress requesting a $ 250 million loan guarantee for Lockheed and its L-1011 Tristar airbus program. The measure

Given limited budgets, air forces were conservative in aircraft design, and biplanes remained popular with pilots for their agility, and remained in service long after they ceased to be competitive. Designs such as the Gloster Gladiator , Fiat CR.42 Falco , and Polikarpov I-15 were common even in the late 1930s, and many were still in service as late as 1942. Up until

On 19 October 2015 the Liberal Party of Canada under Justin Trudeau won a majority in part on a campaign promise to not purchase the F-35, but instead "one of the many, lower-priced options that better match Canada's defence needs". Concerns about the F-35's performance have resulted partially from reports of simulations by RAND Corporation in which three regiments of Chinese Sukhoi Su-27 fighters defeat six F-22s by denying tanker refueling.

In 1943, Lockheed began, in secrecy, development of a new jet fighter at its Burbank facility. This fighter, the Lockheed P-80 Shooting Star , became the first American jet fighter to score a kill. It also recorded the first jet-to-jet aerial kill, downing

The well known and feared Manfred von Richthofen , the "Red Baron", was wearing one when he was killed, but the allied command continued to oppose their use on various grounds. In April 1917, during a brief period of German aerial supremacy a British pilot's average life expectancy was calculated to average 93 flying hours, or about three weeks of active service. More than 50,000 airmen from both sides died during
6783-500: The German invasion. The period of improving the same biplane design over and over was now coming to an end, and the Hawker Hurricane and Supermarine Spitfire started to supplant the Gloster Gladiator and Hawker Fury biplanes but many biplanes remained in front-line service well past the start of World War II. While not a combatant in Spain, they too absorbed many of the lessons in time to use them. The Spanish Civil War also provided an opportunity for updating fighter tactics. One of

Fighter aircraft Fighter aircraft (early on also pursuit aircraft ) are military aircraft designed primarily for air-to-air combat . In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace .

In contrast, designers in the United Kingdom, Germany, the Soviet Union, and the United States believed that the increased speed of fighter aircraft would create g -forces unbearable to pilots who attempted maneuvering dogfights typical of the First World War, and their fighters were instead optimized for speed and firepower. In practice, while light, highly maneuverable aircraft did possess some advantages in fighter-versus-fighter combat, those could usually be overcome by sound tactical doctrine, and

A group of investors headed by brothers Robert and Courtland Gross, and Walter Varney , bought the company out of receivership in 1932. The syndicate bought the company for a mere $ 40,000 ($ 858,000 in 2023). Ironically, Allan Loughead himself had planned to bid for his own company, but had raised only $ 50,000 ($ 824,000), which he felt
7448-509: The Luftwaffe to establish control of the skies over Western Europe. By the time of Operation Overlord in June 1944, the Allies had gained near complete air superiority over the Western Front. This cleared the way both for intensified strategic bombing of German cities and industries, and for the tactical bombing of battlefield targets. With the Luftwaffe largely cleared from the skies, Allied fighters increasingly served as ground attack aircraft. Allied fighters, by gaining air superiority over

In the early 1960s, the company introduced the C-141 Starlifter four-engine jet transport. During the 1960s, Lockheed began development for two large aircraft: the C-5 Galaxy military transport and the L-1011 TriStar wide-body civil airliner. Both projects encountered delays and cost overruns. The C-5

In 1954, the Lockheed C-130 Hercules , a durable four-engined transport, flew for the first time. This type remains in production today. In 1956, Lockheed received a contract for the development of the Polaris Submarine Launched Ballistic Missile ( SLBM ); it would be followed by

The state-run Aviation Industry Corporation of China (AVIC) has been alleged to incorporate
8645-529: The United States, Russia, India and China. The first step was to find ways to reduce the aircraft's reflectivity to radar waves by burying the engines, eliminating sharp corners and diverting any reflections away from the radar sets of opposing forces. Various materials were found to absorb the energy from radar waves, and were incorporated into special finishes that have since found widespread application. Composite structures have become widespread, including major structural components, and have helped to counterbalance

Early fighters were very small and lightly armed by later standards, and most were biplanes built with a wooden frame covered with fabric, and a maximum airspeed of about 100 mph (160 km/h). A successful German biplane, the Albatross, however, was built with a plywood shell, rather than fabric, which created a stronger, faster airplane. As control of

Between the wars, wood was largely replaced in part or whole by metal tubing, and finally aluminum stressed skin structures (monocoque) began to predominate. By World War II , most fighters were all-metal monoplanes armed with batteries of machine guns or cannons and some were capable of speeds approaching 400 mph (640 km/h). Most fighters up to this point had one engine, but

However they too proved unwieldy and vulnerable, so as the war progressed techniques such as drop tanks were developed to extend the range of more nimble conventional fighters. The penetration fighter is typically also fitted for the ground-attack role, and so

Lockheed Martin 's X-35 would become the basis of the F-35 Lightning II , currently in production and service; Pratt & Whitney 's YF119-PW-611 would be the basis for the F135 -PW-600 on the production F-35B. On April 6, 2009, US Secretary of Defense Robert Gates announced that
9709-610: The defense budgets of modern armed forces. The global combat aircraft market was worth $ 45.75 billion in 2017 and is projected by Frost & Sullivan at $ 47.2 billion in 2026: 35% modernization programs and 65% aircraft purchases, dominated by the Lockheed Martin F-35 with 3,000 deliveries over 20 years. A fighter aircraft is primarily designed for air-to-air combat . A given type may be designed for specific combat conditions, and in some cases for additional roles such as air-to-ground fighting. Historically
9842-724: The design approach of the Italians and Japanese made their fighters ill-suited as interceptors or attack aircraft. During the invasion of Poland and the Battle of France , Luftwaffe fighters—primarily the Messerschmitt Bf 109 —held air superiority, and the Luftwaffe played a major role in German victories in these campaigns. During the Battle of Britain , however, British Hurricanes and Spitfires proved roughly equal to Luftwaffe fighters. Additionally Britain's radar-based Dowding system directing fighters onto German attacks and
9975-522: The early 1960s since both were believed unusable at the speeds being attained, however the Vietnam War showed that guns still had a role to play, and most fighters built since then are fitted with cannon (typically between 20 and 30 mm (0.79 and 1.18 in) in caliber) in addition to missiles. Most modern combat aircraft can carry at least a pair of air-to-air missiles. In the 1970s, turbofans replaced turbojets, improving fuel economy enough that
10108-586: The enemy from doing the same. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers , are designed from
10241-503: The entirety of American involvement in the war, from Pearl Harbor to Victory over Japan Day . It filled ground-attack, air-to-air, and even tactical bombing roles in all theaters of the war in which the United States operated. The P-38 was responsible for shooting down more Japanese aircraft than any other U.S. Army Air Forces type during the war; it is particularly famous for being the aircraft type that shot down Japanese Admiral Isoroku Yamamoto 's airplane. The Lockheed Vega factory
10374-455: The faltering economy and worries about unemployment while testifying "the time has come within the United States when we have to look at things differently. Free enterprise is just not all that free." Questions arose whether letting Lockheed fail would be bad for the market due to decreased competition or good by screening out inefficient competitors and mismanagement. Lockheed's competitors, McDonnell Douglas and General Electric (collaborators on
10507-513: The fighter. Rifle-caliber .30 and .303 in (7.62 and 7.70 mm) calibre guns remained the norm, with larger weapons either being too heavy and cumbersome or deemed unnecessary against such lightly built aircraft. It was not considered unreasonable to use World War I-style armament to counter enemy fighters as there was insufficient air-to-air combat during most of the period to disprove this notion. The rotary engine , popular during World War I, quickly disappeared, its development having reached
10640-475: The fighting qualities of particular fighter aircraft." Furthermore, Maj. Richard Koch, chief of USAF Air Combat Command's advanced air dominance branch is reported to have said that "I wake up in a cold sweat at the thought of the F-35 going in with only two air-dominance weapons" with an Aviation Week article casting an extremely skeptical eye over the (USAF) source of claims that the F-35 would be "400% more effective" than projected opponents. The experience of
10773-406: The guns were subjected). Shooting with this traditional arrangement was also easier because the guns shot directly ahead in the direction of the aircraft's flight, up to the limit of the guns range; unlike wing-mounted guns which to be effective required to be harmonised , that is, preset to shoot at an angle by ground crews so that their bullets would converge on a target area a set distance ahead of
10906-433: The innovations was the development of the " finger-four " formation by the German pilot Werner Mölders . Each fighter squadron (German: Staffel ) was divided into several flights ( Schwärme ) of four aircraft. Each Schwarm was divided into two Rotten , which was a pair of aircraft. Each Rotte was composed of a leader and a wingman. This flexible formation allowed the pilots to maintain greater situational awareness, and
11039-514: The interceptor. The equipment necessary for daytime flight is inadequate when flying at night or in poor visibility. The night fighter was developed during World War I with additional equipment to aid the pilot in flying straight, navigating and finding the target. From modified variants of the Royal Aircraft Factory B.E.2c in 1915, the night fighter has evolved into the highly capable all-weather fighter. The strategic fighter
11172-420: The last piston engine support aircraft could be replaced with jets, making multi-role combat aircraft possible. Honeycomb structures began to replace milled structures, and the first composite components began to appear on components subjected to little stress. With the steady improvements in computers, defensive systems have become increasingly efficient. To counter this, stealth technologies have been pursued by
11305-553: The late 1980s, leveraged buyout specialist Harold Simmons conducted a widely publicized but unsuccessful takeover attempt on the Lockheed Corporation, having gradually acquired almost 20 percent of its stock. Lockheed was attractive to Simmons because one of its primary investors was the California Public Employees' Retirement System (CalPERS), the pension fund of the state of California. At
11438-637: The leadership vacuum within the Soviet military left by the Great Purge , and the general inferiority of Soviet designs at the time, such as the obsolescent Polikarpov I-15 biplane and the I-16 . More modern Soviet designs, including the Mikoyan-Gurevich MiG-3 , LaGG-3 and Yakolev Yak-1 , had not yet arrived in numbers and in any case were still inferior to the Messerschmitt Bf 109 . As
11571-407: The loan. (Later, historian Stephen J. Whitfield viewed the passage of the loan guarantee as a support for the argument that America was shifting away from Lockean liberalism. ) Following a fierce debate, Vice President Spiro T. Agnew cast a tie-breaking vote in favor of the measure on August 2, 1971. President Nixon signed the bill into law on August 9, 1971 - which became colloquially known as
11704-533: The method of achieving STOVL flight, with the Department of Defense judging that the higher performance lift fan system was worth the extra risk. When near to the ground, the Boeing X-32 suffered from the problem of hot air from the exhaust circulating back to the main engine, which caused the thrust to weaken and the engine to overheat. The United States Department of Defense officials and William Bach ,
11837-458: The mid-1930s, the majority of fighters in the US, the UK, Italy and Russia remained fabric-covered biplanes. Fighter armament eventually began to be mounted inside the wings, outside the arc of the propeller, though most designs retained two synchronized machine guns directly ahead of the pilot, where they were more accurate (that being the strongest part of the structure, reducing the vibration to which
11970-495: The most modern weapons, against an enemy in complete command of the air, fights like a savage…" Throughout the war, fighters performed their conventional role in establishing air superiority through combat with other fighters and through bomber interception, and also often performed roles such as tactical air support and reconnaissance . Fighter design varied widely among combatants. The Japanese and Italians favored lightly armed and armored but highly maneuverable designs such as
12103-607: The opposition. Subsequently, radar capabilities grew enormously and are now the primary method of target acquisition . Wings were made thinner and swept back to reduce transonic drag, which required new manufacturing methods to obtain sufficient strength. Skins were no longer sheet metal riveted to a structure, but milled from large slabs of alloy. The sound barrier was broken, and after a few false starts due to required changes in controls, speeds quickly reached Mach 2, past which aircraft cannot maneuver sufficiently to avoid attack. Air-to-air missiles largely replaced guns and rockets in
12236-488: The outbreak of World War I , front-line aircraft were mostly unarmed and used almost exclusively for reconnaissance . On 15 August 1914, Miodrag Tomić encountered an enemy airplane while on a reconnaissance flight over Austria-Hungary which fired at his aircraft with a revolver, so Tomić fired back. It was believed to be the first exchange of fire between aircraft. Within weeks, all Serbian and Austro-Hungarian aircraft were armed. Another type of military aircraft formed
12369-451: The outset for dual roles. Other fighter designs are highly specialized while still filling the main air superiority role, and these include the interceptor and, historically, the heavy fighter and night fighter . Since World War I, achieving and maintaining air superiority has been considered essential for victory in conventional warfare . Fighters continued to be developed throughout World War I, to deny enemy aircraft and dirigibles
12502-487: The period of rapid re-armament in the late 1930s, were not military budgets, but civilian aircraft racing. Aircraft designed for these races introduced innovations like streamlining and more powerful engines that would find their way into the fighters of World War II. The most significant of these was the Schneider Trophy races, where competition grew so fierce, only national governments could afford to enter. At
12635-433: The period, going from a typical 180 hp (130 kW) in the 900 kg (2,000 lb) Fokker D.VII of 1918 to 900 hp (670 kW) in the 2,500 kg (5,500 lb) Curtiss P-36 of 1936. The debate between the sleek in-line engines versus the more reliable radial models continued, with naval air forces preferring the radial engines, and land-based forces often choosing inlines. Radial designs did not require
12768-456: The pilot's maneuvering with the gunner's aiming was difficult. This option was chiefly employed as a defensive measure on two-seater reconnaissance aircraft from 1915 on. Both the SPAD S.A and the Royal Aircraft Factory B.E.9 added a second crewman ahead of the engine in a pod but this was both hazardous to the second crewman and limited performance. The Sopwith L.R.T.Tr. similarly added a pod on
12901-451: The pilots reported. Attempts were made with handheld weapons such as pistols and rifles and even light machine guns, but these were ineffective and cumbersome. The next advance came with the fixed forward-firing machine gun, so that the pilot pointed the entire aircraft at the target and fired the gun, instead of relying on a second gunner. Roland Garros bolted metal deflector plates to the propeller so that it would not shoot itself out of
13034-410: The point where rotational forces prevented more fuel and air from being delivered to the cylinders, which limited horsepower. They were replaced chiefly by the stationary radial engine though major advances led to inline engines gaining ground with several exceptional engines—including the 1,145 cu in (18,760 cm ) V-12 Curtiss D-12 . Aircraft engines increased in power several-fold over
13167-460: The program will be delayed one year. According to some estimates, overruns could increase the program's total costs to $ 388 billion, a 50% increase from the initial price tag. Many of the program's financial and technical complications result from the Marine version of the JSF, capable of vertical take-offs and landings. On 11 March 2010, United States Senate Committee on Armed Services investigated
13300-559: The progress of the JSF program in a meeting with Pentagon officials, emphasizing cost due to the risk of a Nunn-McCurdy process. According to the Government Accountability Office , F-35A cost has risen from $ 50m in 2002, via $ 69m in 2007 to $ 74m in 2010, all measured in 2002 dollars. Canada reviewed their commitment to the project in December 2012, due to the cost overruns. The decision was made following
13433-575: The propeller arc was evident even before the outbreak of war and inventors in both France and Germany devised mechanisms that could time the firing of the individual rounds to avoid hitting the propeller blades. Franz Schneider , a Swiss engineer, had patented such a device in Germany in 1913, but his original work was not followed up. French aircraft designer Raymond Saulnier patented a practical device in April 1914, but trials were unsuccessful because of
13566-461: The propeller arc. Wing guns were tried but the unreliable weapons available required frequent clearing of jammed rounds and misfires and remained impractical until after the war. Mounting the machine gun over the top wing worked well and was used long after the ideal solution was found. The Nieuport 11 of 1916 used this system with considerable success, however, this placement made aiming and reloading difficult but would continue to be used throughout
13699-458: The propeller blades were fitted with metal wedges to protect them from ricochets . Garros' modified monoplane first flew in March 1915 and he began combat operations soon after. Garros scored three victories in three weeks before he himself was downed on 18 April and his airplane, along with its synchronization gear and propeller was captured by the Germans. Meanwhile, the synchronization gear (called
13832-426: The propensity of the machine gun employed to hang fire due to unreliable ammunition. In December 1914, French aviator Roland Garros asked Saulnier to install his synchronization gear on Garros' Morane-Saulnier Type L parasol monoplane . Unfortunately the gas-operated Hotchkiss machine gun he was provided had an erratic rate of fire and it was impossible to synchronize it with the propeller. As an interim measure,
13965-410: The ramifications of the Lockheed loan guarantee soon resurfaced in late 1975 with discussions on possible aid to New York City during its fiscal crisis . Lockheed finished paying off the $ 1.4 billion loan in 1977, along with about $ 112.22 million in loan guarantee fees. The Lockheed bribery scandals were a series of illegal bribes and contributions made by Lockheed officials from the late 1950s to
14098-535: The same technology originally developed for the Model S-1 to design the Vega Model . In March 1928, the company relocated to Burbank, California , and by year's end reported sales exceeding one million dollars. From 1926 to 1928 the company produced over 80 aircraft and employed more than 300 workers who by April 1929 were building five aircraft per week. In July 1929, majority shareholder Fred Keeler sold 87% of
14231-483: The similarly named but otherwise-unrelated Loughead Aircraft Manufacturing Company , which was operational from 1912 to 1920. Allan Loughead and his brother Malcolm Loughead had operated an earlier aircraft company, Loughead Aircraft Manufacturing Company , which was operational from 1912 to 1920. The company built and operated aircraft for paying passengers on sightseeing tours in California and had developed
14364-532: The skies above the battlefield. The interceptor is a fighter designed specifically to intercept and engage approaching enemy aircraft. There are two general classes of interceptor: relatively lightweight aircraft in the point-defence role, built for fast reaction, high performance and with a short range, and heavier aircraft with more comprehensive avionics and designed to fly at night or in all weathers and to operate over longer ranges . Originating during World War I, by 1929 this class of fighters had become known as
14497-417: The sky and a number of Morane-Saulnier Ns were modified. The technique proved effective, however the deflected bullets were still highly dangerous. Soon after the commencement of the war, pilots armed themselves with pistols, carbines , grenades , and an assortment of improvised weapons. Many of these proved ineffective as the pilot had to fly his airplane while attempting to aim a handheld weapon and make
14630-408: The steady increases in aircraft weight—most modern fighters are larger and heavier than World War II medium bombers. Because of the importance of air superiority, since the early days of aerial combat armed forces have constantly competed to develop technologically superior fighters and to deploy these fighters in greater numbers, and fielding a viable fighter fleet consumes a substantial proportion of
14763-469: The takeover since he was also at the time pursuing control of Georgia Gulf . Merger talks between Lockheed and Martin Marietta began in March 1994, with the companies announcing their $ 10 billion planned merger on August 30, 1994. The headquarters for the combined companies would be at Martin Marietta headquarters in North Bethesda, Maryland . The deal was finalized on March 15, 1995, when
14896-465: The time, the New York Times said, "Much of Mr. Simmons's interest in Lockheed is believed to stem from its pension plan, which is over funded by more than $ 1.4 billion. Analysts said he might want to liquidate the plan and pay out the excess funds to shareholders, including himself." Citing the mismanagement by its chairman, Daniel M. Tellep , Simmons stated a wish to replace its board with
15029-485: The top wing with no better luck. An alternative was to build a "pusher" scout such as the Airco DH.2 , with the propeller mounted behind the pilot. The main drawback was that the high drag of a pusher type's tail structure made it slower than a similar "tractor" aircraft. A better solution for a single seat scout was to mount the machine gun (rifles and pistols having been dispensed with) to fire forwards but outside
15162-464: The two Rotten could split up at any time and attack on their own. The finger-four would be widely adopted as the fundamental tactical formation during World War Two, including by the British and later the Americans. World War II featured fighter combat on a larger scale than any other conflict to date. German Field Marshal Erwin Rommel noted the effect of airpower: "Anyone who has to fight, even with
15295-500: The two companies' shareholders approved the merger. The segments of the two companies not retained by the new company formed the basis for L-3 Communications , a mid-size defense contractor in its own right. Lockheed Martin also later spun off the materials company Martin Marietta Materials . The company's executives received large bonuses directly from the government as a result of the merger. Norman R. Augustine who
15428-603: The very end of the inter-war period in Europe came the Spanish Civil War . This was just the opportunity the German Luftwaffe , Italian Regia Aeronautica , and the Soviet Union's Voenno-Vozdushnye Sily needed to test their latest aircraft. Each party sent numerous aircraft types to support their sides in the conflict. In the dogfights over Spain, the latest Messerschmitt Bf 109 fighters did well, as did
15561-478: The war as the weapons used were lighter and had a higher rate of fire than synchronized weapons. The British Foster mounting and several French mountings were specifically designed for this kind of application, fitted with either the Hotchkiss or Lewis Machine gun , which due to their design were unsuitable for synchronizing. The need to arm a tractor scout with a forward-firing gun whose bullets passed through
15694-443: The war. Fighter development stagnated between the wars, especially in the United States and the United Kingdom, where budgets were small. In France, Italy and Russia, where large budgets continued to allow major development, both monoplanes and all metal structures were common. By the end of the 1920s, however, those countries overspent themselves and were overtaken in the 1930s by those powers that hadn't been spending heavily, namely
15827-716: The world in 1937. Subsequent designs, the Lockheed Model 12 Electra Junior and the Lockheed Model 14 Super Electra expanded their market. The Lockheed Model 14 formed the basis for the Hudson bomber, which was supplied to both the British Royal Air Force and the United States military before and during World War II . Its primary role was submarine hunting. The Model 14 Super Electra were sold abroad, and more than 100 were license-built in Japan for use by
15960-695: Was at the time CEO of Martin Marietta received an $ 8.2 million bonus. Both companies contributed important products to the new portfolio. Lockheed products included the Trident missile , P-3 Orion maritime patrol aircraft , U-2 and SR-71 reconnaissance airplanes , F-117 Nighthawk , F-16 Fighting Falcon , F-22 Raptor , C-130 Hercules , A-4AR Fightinghawk and the DSCS-3 satellite. Martin Marietta products included Titan rockets , Sandia National Laboratories (management contract acquired in 1993), Space Shuttle External Tank , Viking 1 and Viking 2 landers,
16093-593: Was built in any number (141 aircraft) was the Vega first built in 1927, best known for its several first- and record-setting flights by, among others, Amelia Earhart , Wiley Post , and George Hubert Wilkins . In the 1930s, Lockheed spent $ 139,400 ($ 2.29 million) to develop the Model 10 Electra , a small twin-engined transport. The company sold 40 in the first year of production. Amelia Earhart and her navigator, Fred Noonan , flew it in their failed attempt to circumnavigate
16226-718: Was built to vague initial requirements and suffered from structural weaknesses, which Lockheed was forced to correct at its own expense. The TriStar competed for the same market as the McDonnell Douglas DC-10 ; delays in Rolls-Royce engine development caused the TriStar to fall behind the DC-10. The C-5 and L-1011 projects, the canceled U.S. Army AH-56 Cheyenne helicopter program, and embroiled shipbuilding contracts caused Lockheed to lose large sums of money during
16359-646: Was chosen after Paul Bevilaqua persuaded the Air Force that his team's concept (if stripped of its lift system ) had potential as a complement to the F-22 Raptor . The Joint Advanced Strike Technology (JAST) program was created in 1993, implementing one of the recommendations of a United States Department of Defense (DoD) "Bottom-Up Review to include the United States Navy in the Common Strike Fighter program." The review also led
16492-433: Was denied by Comptroller General Elmer B. Staats , and efforts were made by Senator William Proxmire to get Treasury Secretary John Connally to testify due to the suspicion that the loan guarantee was in jeopardy. The editorial board of The New York Times blasted the situation, citing it as another argument against the propriety of the loan guarantee and the precedent it set for other failing companies. The debate around
16625-400: Was easily foreseen as the post-war modernization of civilian air travel. The Constellation's performance set new standards which transformed the civilian transportation market. Its signature tri-tail was the result of many initial customers not having hangars tall enough for a conventional tail. Lockheed produced a larger transport, the double-decked R6V Constitution , which was intended to make
16758-518: Was hotly debated in the US Senate. The chief antagonist was Senator William Proxmire (D-Wis), the nemesis of Lockheed and its chairman, Daniel J. Haughton. Some of the debate in Congress developed over what conditions should be attached to the bailout. Senator Alan Cranston demanded that the management be forced to step down, lest it set a precedent rewarding wasteful spending. Others argued that
16891-538: Was located next to Burbank's Union Airport which it had purchased in 1940. During the war, the entire area was camouflaged in case of enemy reconnaissance. The factory was hidden beneath a huge burlap tarpaulin painted to depict a peaceful semi-rural neighborhood, replete with rubber automobiles. Hundreds of fake trees, shrubs, buildings, and even fire hydrants were positioned to give a three-dimensional appearance. The trees and shrubs were created from chicken wire treated with an adhesive and covered with feathers to provide
17024-420: Was no longer a handicap and one or two were used, depending on requirements. This in turn required the development of ejection seats so the pilot could escape, and G-suits to counter the much greater forces being applied to the pilot during maneuvers. In the 1950s, radar was fitted to day fighters, since due to ever increasing air-to-air weapon ranges, pilots could no longer see far enough ahead to prepare for
17157-485: Was originally intended for a fighter role with the U.S. Navy , but it was canceled. This blurring follows the use of fighters from their earliest days for "attack" or "strike" operations against ground targets by means of strafing or dropping small bombs and incendiaries. Versatile multi role fighter-bombers such as the McDonnell Douglas F/A-18 Hornet are a less expensive option than having
17290-508: Was pioneered before World War I by Breguet but would find its biggest proponent in Anthony Fokker, who used chrome-molybdenum steel tubing for the fuselage structure of all his fighter designs, while the innovative German engineer Hugo Junkers developed two all-metal, single-seat fighter monoplane designs with cantilever wings: the strictly experimental Junkers J 2 private-venture aircraft, made with steel, and some forty examples of
17423-564: Was rejected in part due to the complexity of its design. Lockheed Martin and Boeing were each given $ 750 million to develop their concept demonstrators and the definition of the Preferred Weapon System Concept (PWSC). The aim of this funding limit was to prevent one or both contractors from bankrupting themselves in an effort to win such an important contract. Also in 1996, the UK Ministry of Defence launched
17556-502: Was the final qualifying Joint Strike Fighter flight trials, in which the X-35B STOVL aircraft took off in less than 500 feet (150 m), went supersonic, and landed vertically – a feat that Boeing 's entry was unable to achieve. The contract for System Development and Demonstration (SDD) was awarded on 26 October 2001 to Lockheed Martin, whose X-35 beat the Boeing X-32 . One of the main reasons for this choice appears to have been
17689-582: Was too small a sum for a serious bid. In 1934, Robert E. Gross was named chairman of the new company, the Lockheed Aircraft Corporation, which was headquartered at what is now the airport in Burbank, California . His brother Courtlandt S. Gross was a co-founder and executive, succeeding Robert as chairman following his death in 1961. The company was named the Lockheed Corporation in 1977. The first successful construction that
