127-620: The Atlas Cheetah is a South African fighter aircraft designed and produced by the aviation company Atlas Aircraft Corporation (later Denel Aeronautics ). It was primarily designed and developed to be operated by the South African Air Force (SAAF). The Cheetah was developed amid the Border War of the 1980s as a major upgrade of the French-built Dassault Mirage III fleet operated by
254-473: A forward-looking infrared (FLIR) sensor under the aircraft's nose/cockpit, being designated ROSE II. The cockpits included new MFDs, HUDs, HOTAS controls, radar altimeters and RWRs. Additionally, 14 Mirage 5F fighters from the second batch were similarly upgraded but with newer systems and designated ROSE III. The FLIR sensors allow the Mirage 5 ROSE fighters to specialise in the night-time attack role. During

An indigenously developed helmet-mounted sight (HMS) and an oversized head-up display (HUD) were also installed in the cockpit, along with other sophisticated cockpit instrumentation. The upgrade involved
508-584: 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
635-470: 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
762-435: 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
889-443: 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
1016-552: 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
1143-664: 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
1270-580: A more modern cockpit, a new ejection seat, a laser rangefinder , and canards to improve takeoff performance and overall maneuverability. A new government canceled the MIRSIP but SABCA was allowed to carry out the update, in order to sell the aircraft on the export market. After completion, the Belgian government sold all 20 aircraft to Chile, together with 4 non-upgraded Mirage 5BRs, and one non-upgraded Mirage 5BD. The development and subsequent installation of

#17327762130601524-431: 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
1651-550: 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
1778-522: A quantity of Mirage 50s, receiving both new production as well as updated Armée de l'Air Mirage 5s. The Chilean aircraft were later modernised along the lines of the IAI Kfir and were called the ENAER Pantera. The Pantera incorporates fixed canards and other aerodynamic improvements, as well as advanced avionics . These aircraft have an extended nose to accommodate some of the new systems. In
1905-638: 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
2032-742: 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
2159-643: 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
2286-420: 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
2413-500: A total of five IAI Nesher fighters may have been acquired from the Israeli Air Force for Cheetah trials and later absorbed into the existing fleet. According to aviation author John W. Golan, a potentially large number of IAI Kfirs may have been provided to South Africa for the programme. The upgrade consisted of a complete refurbishment of the airframe down to zero flight hours condition; to achieve this, roughly 50% of
2540-402: Is a fast, heavily armed and long-range type, able to act as an escort fighter protecting bombers , to carry out offensive sorties of its own as a penetration fighter and maintain standing patrols at significant distance from its home base. 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
2667-549: 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

#17327762130602794-565: Is currently with the SAAF Museum, and is stored at AFB Swartkop . In 2003, Chile purchased five of the mothballed aircraft (Numbers 819, 820, 827, 832 and 833) and indicated its desire to purchase seven more aircraft (numbers 822, 823, 825, 828, 829, 831 and 834) subject to the agreement of a suitable purchase price. The Chilean Air Force (FACh) used the Cheetah E airframes as a source of spares for its similar ENAER Pantera aircraft until these planes were retired in late 2006. The Cheetah R

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
3048-562: 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
3175-620: The Dassault-Dornier Alpha Jet . In 1982, Pakistan Chief of Air Staff ACM ( Gen. ) Anwar Shamim acquired an additional squadron of the Mirage 5 from France to provide effective support to the Navy. In 1978 and 1980, Israel sold a total of 35 of their Neshers plus 4 Nesher trainer aircraft (Nesher Ts) to Argentina , where they were locally known first as Daggers and after their upgrade as Fingers . The Argentines lost two Mirage IIIEAs and twelve Daggers during
3302-546: The Ecuadorian Air Force (EAF) as a source of spare parts. The privately owned company Draken International intends to use the Cheetah as an adversarial aircraft for combat training services in the United States. The Atlas Cheetah programme originated during the 1980s out of South Africa's requirement for more capable fighter and strike aircraft. At the time, the South African Air Force (SAAF)
3429-626: The Falklands War in 1982. As a measure of solidarity, the Peruvians transferred ten of their Mirage 5Ps to Argentina, under the name Mirage Mara , to help alleviate its losses. South Africa purchased five Nesher trainers for trials during its own Atlas Cheetah fighter programme. All the aircraft were eventually upgraded to Cheetah D standard. Chile incorporated some Mirage 5s under name Mirage Elkan . A total of 582 Mirage 5s were built, including 51 Israeli Neshers. In 1968,

Officially, Israel claimed to have built the aircraft after obtaining complete blueprints, naming them IAI Nesher . Like the Mirage IIIE, the Mirage 5 was popular with export customers, with different export variants fitted with a wide range of different avionics. While the Mirage 5 had been originally oriented to
3683-585: The Junkers D.I , made with corrugated duralumin , all based on his experience in creating the pioneering Junkers J 1 all-metal airframe technology demonstration aircraft of late 1915. While Fokker would pursue steel tube fuselages with wooden wings until the late 1930s, and Junkers would focus on corrugated sheet metal, Dornier was the first to build a fighter (the Dornier-Zeppelin D.I ) made with pre-stressed sheet aluminum and having cantilevered wings,
3810-510: The RAF and the USAAF against German industry intended to wear down the Luftwaffe. 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
3937-588: The Sopwith Tabloid and Bristol Scout . 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

In September 1966, the Israelis placed an order for 50 of the new aircraft. Due to customer preference some variants of the Mirage 5 were radar-equipped. The first Mirage 5 flew on 19 May 1967. It looked much like

Retired Cheetahs were typically stored rather than scrapped, and during 2003, South Africa began seeing buyers for these surplus aircraft. Accordingly, the Cheetah has been exported to various customers. In South America , Ecuador decided to acquire
4699-622: The Belgian government ordered 106 Mirage 5s from Dassault to re-equip No 3 Wing at Bierset air base. All aircraft but the first one were to be license-built by SABCA in Belgium. Component production at the SABCA Haren plant near Brussels was followed by assembly at the SABCA plant at Gosselies airfield, near Charleroi. The ATAR engines were produced by FN Moteurs at this company's Liège plant. SABCA production included three versions: Mirage 5BA for
4826-668: The British Royal Flying Corps and Royal Air Force referred to them as " scouts " until the early 1920s, while the U.S. Army called them "pursuit" aircraft until the late 1940s (using the designation P, as in Curtiss P-40 Warhawk , Republic P-47 Thunderbolt and Bell P-63 Kingcobra ). The UK changed to calling them fighters in the 1920s , while the US Army did so in the 1940s. A short-range fighter designed to defend against incoming enemy aircraft
4953-639: The British, the Americans, the Spanish (in the Spanish civil war) and the Germans. 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

The second and third aircraft to be delivered to Atlas were both Mirage IIIEZs, following their conversion of the Cheetah E configuration, these aircraft went into service with 5 Squadron at AFB Louis Trichardt . Early experiences with the Cheetah found it to be markedly more difficult to successfully perform in-flight refuelling than
5207-912: The Cheetah R programme and 855 was assigned to the Atlas Advanced Combat Wing (ACW) where it was used as a testing and development aircraft.

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
5588-618: 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
5715-756: The Italians developed several monoplanes such as the Fiat G.50 Freccia , but being short on funds, were forced to continue operating obsolete Fiat CR.42 Falco biplanes. From the early 1930s the Japanese were at war against both the Chinese Nationalists and the Russians in China, and used the experience to improve both training and aircraft, replacing biplanes with modern cantilever monoplanes and creating
5842-905: The Japanese Nakajima Ki-27 , Nakajima Ki-43 and Mitsubishi A6M Zero and the Italian Fiat G.50 Freccia and Macchi MC.200 . 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

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
6096-662: The Luftwaffe, and while the Luftwaffe maintained a qualitative edge over the Red Air Force for much of the war, the increasing numbers and efficacy of the Soviet Air Force were critical to the Red Army's efforts at turning back and eventually annihilating the Wehrmacht . Meanwhile, air combat on the Western Front had a much different character. Much of this combat focused on the strategic bombing campaigns of
6223-460: The Mirage F1 fleet. While the type had been developed in response to the increasing pressure of the Border War , there is no evidence that any Cheetahs of any variant actually conducted offensive operations in the final years of the conflict. By 1991, 16 of each type were reported in service when the Cheetah D and E conversion lines closed. This same year, the production of the Cheetah C started,

In terms of its electronics and systems, the Cheetah was provisioned with new avionics , radar set, electronic warfare (EW) and self-protection suites . As many of these were accommodated within the nose, this necessitated its lengthening to provide more internal space. The EW suite incorporated

A pitot tube was distinctively moved from the tip of the nose to below the nose in the majority of Mirage 5 variants. The Mirage 5 retained the IIIE's twin DEFA guns, but added two additional pylons, for a total of seven. Maximum warload was 4,000 kg (8,800 lb). Provision for

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

9271-668: 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
9398-451: The designation Mirage 5R , and Mirage 5D respectively. The Mirage 5 was sold to Abu Dhabi , Belgium , Colombia , Egypt , Gabon , Libya , Pakistan , Peru , Venezuela , and Zaire , with the usual list of subvariant designations and variations in kit. The Belgian aircraft were fitted with mostly US avionics, and some Egyptian aircraft were fitted with the MS2 attack avionics system from
9525-522: 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
9652-456: The early 1990s, Dassault upgraded a batch of Venezuelan Mirage IIIEVs and 5s to Mirage 50 standards. In the 1990s, the PAF launched a Mid-life update (MLU) program, codenamed as Project ROSE (Retrofit Of Strike Element), to its aging Mirage III and Mirage 5 aircraft with modern avionics provided by French, Italian, and Pakistani software conglomerates. The PAF acquired blueprint drawings of
9779-435: The embedding of Israelí advisors within SAAF units. According to some aviation publications, foreign aviation company Israel Aircraft Industries had been involved in at least the initial stages of the upgrade, and that some components were sourced directly from Israel. IAI themselves have acknowledged their involvement in the joint development of related projects, such as an active-radar development programme. According to ACIG,
9906-513: 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
10033-408: The first such aircraft being rolled out during January 1993. All the Cheetah Cs entered service with 2 Squadron , which was also stationed at AFB Louis Trichardt. The type continued to be used during the post-Apartheid peacetime, but became increasingly obsolete in comparison to international fighter aircraft over the course of two decades. The Cheetah was eventually withdrawn from SAAF service during
10160-462: The fitting of a new and capable Pulse-Doppler radar system. While both the Cheetah D and the Cheetah E were still equipped with the SNECMA Atar 9C turbojet engine, the Cheetah C used the more powerful Atar 9K50. On 16 July 1986, the first Cheetah D was publicly unveiled although a number of Cheetah Ds had already entered service with 89 Combat Flying School at AFB Pietersburg. During 1987,
10287-523: The fitting of a single-piece wrap-around windshield in place of the previous three-piece version, a revised in-flight refuelling probe with less external piping, new undercarriage and suspension, the deletion of the wing fences, an Atar 9K50 engine and a new nose to incorporate the more sophisticated electronics and radar. Like the Cheetah D, the Cheetah C was capable of delivering precision-guided munitions (PGMs), ranging from laser-guided bombs (LGBs), to GPS-guided weapons and TV-guided bombs. It also had
10414-416: The ground-attack role, Mirage 5BR for the reconnaissance role and Mirage 5BD for training and conversion. By the end of the 1980s, a MIRage Safety Improvement Program (MIRSIP) was agreed to by parliament, calling for 20 low-time Mirages (15 Mirage 5BAs and 5 Mirage 5BDs) to be upgraded. Initial plans included a new more powerful engine, but this idea was abandoned to limit cost. The upgrade eventually included
10541-406: 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
10668-407: The increasing age of existing aircraft in the SAAF's inventory also needed to be addressed. As a consequence of the arms embargo being imposed at the time under United Nations Security Council Resolution 418 , South Africa was prevented from purchasing new aircraft from almost any other country in the world; accordingly, the upgrading of existing aircraft became the only viable option available. By
10795-433: 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
10922-514: 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
11049-420: 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
11176-407: The latter being based on the Mirage III. Consequently, the SAAF's Mirage III fleet was chosen as the recipient for this upgrade programme, which was initially referred to as Project Cushion . The work was carried out by Atlas Aviation (formerly Atlas Aircraft Corporation and lately Denel Aviation ). Atlas was also able to acquire skilled technicians with relevant knowledge from Israel , following
11303-637: 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
11430-506: 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
11557-495: 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
11684-413: The new Atar 09K-50 engine led to the next Mirage variant, the Mirage 50 , during the 1970s. The uprated engine gave the Mirage 50 better takeoff and climb characteristics than its predecessors. The Mirage 50 also incorporated new avionics, such as a Cyrano IV radar system. However, despite these upgrades, it did not prove popular in export sales as the Mirage 5 itself was becoming obsolete. Chile ordered
11811-607: 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
11938-445: The original airframe was reportedly replaced, according to statements made by Atlas. Aerodynamic changes included the installation of non-moving canards just aft of the engine intakes, the Cheetah D & E models were fitted with slightly smaller (70%) canards than that of the Cheetah C and IAI Kfir. Other airframe alterations included two additional stores pylons at the wing roots , an aerial refuelling probe , new ejection seats ,
12065-488: 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
12192-451: 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
12319-487: 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
12446-433: 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
12573-456: 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
12700-451: 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
12827-410: 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
12954-575: 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
13081-461: 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
13208-458: 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
13335-426: 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,
13462-421: The role of fighter aircraft is to establish air superiority of the battlespace . Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets, and helps prevent 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
13589-532: 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
13716-417: 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
13843-408: 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
13970-420: 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
14097-485: 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
14224-464: 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
14351-462: The type. During late 2017, it was announced that a privately owned company , Draken International , had made a deal with Denel Aviation to procure much of the ex-SAAF fleet; the company reportedly intended to use the Cheetah as an aggressor aircraft for dissimilar combat training services for customers in the United States . The Cheetah C was the final development in the Cheetah series and
14478-542: 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
14605-478: 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
14732-443: 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
14859-484: Was a feasibility study into an extension of the Cheetah upgrade programme to include a specialist reconnaissance model. An Atar 9K50-engined Mirage IIIR2Z, (855), was chosen as the airframe for the upgrade. In addition to the airframe refurbishment, 855 received a new nose design and the same radar as used in the Cheetah E, the twin DEFA 30mm cannons were removed and it was the only Cheetah type to not receive an in-flight refuelling probe. The SAAF decided not to proceed with
14986-500: Was also initiated around the same time. During the 1980s, the SAAF's fast jet fleet consisted of multiple variants of the French -built Dassault Mirage III (EZ/CZ/BZ/DZ/D2Z/RZ/R2Z) and Mirage F1 (AZ/CZ) aircraft. Although the Mirage F1 was considered to be the most modern aircraft type in the fleet, deliveries having commenced during 1977, the type comprised the primary element of South Africa's air defence and strike fleet. Withdrawing
15113-667: Was based at the Test Flight and Development Centre (TFDC) as a systems testing aircraft and used in the development of the Denel Dynamics MUPSOW stand-off weapon. Denel used two Cheetah Ds for testing (844 and 847). The former was Denel's standard systems testing aircraft, while the latter was used in the evaluation of the SMR-95 engine, a development of the Soviet -built Klimov RD-33 . The performance increase offered by
15240-551: Was built as a prototype, but this variant never entered service. During 1992, the Cheetah E model was withdrawn from SAAF service; both the Cheetah Cs and Cheetah Ds were retired during April 2008, having been being replaced by the Swedish-built Saab Gripen . Since its retirement by the SAAF, a limited number have still operated in South Africa as flight test aircraft. Some have been exported, such as to
15367-486: Was confronted by the need for more advanced aircraft to attain an edge over the ever-more sophisticated Soviet -built aircraft, such as the MiG-23 , that were being supplied to both Angolan and Cuban forces. These aircraft were being deployed against South Africa's own military during the lengthy conflict commonly known as the Border War . Furthermore, the increasing cost of maintenance due to international sanctions and
15494-470: Was derived from Dassault's popular Mirage III fighter and spawned several variants of its own, including the IAI Kfir . In Pakistan's service, the Mirage 5s are modified and are capable of nuclear weapons delivery . The Mirage 5 grew out of a request to Dassault from the Israeli Air Force . Since the weather over the Middle East is clear and sunny most of the time, the Israelis suggested removing
15621-499: Was fitted with a comparatively simple avionics suite and radar and retained the Atar 9C-3 engine. Its typical mission was as a standby interceptor, whereby a minimum of two aircraft armed with two V3B (later V3C) missiles, would be on permanent alert status in case of an attack from the north. All aircraft were placed into storage with the final example (No.842) painted in a non-standard camouflage scheme and used for systems testing. No.842
15748-420: 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
15875-485: 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
16002-508: 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
16129-521: Was the only fighter aircraft in service with the SAAF until replaced by the Swedish -built Saab JAS 39 Gripen during 2008. In addition to the upgrades described above, the Cheetah C incorporated more sophisticated avionics and navigation suite and an improved pulse-doppler multi-mode radar (ELTA). The aircraft was also fitted with a data link and updated versions of the helmet-mounted sight, HUD and improved HOTAS controls. Other improvements included
