105-560: In March 1930, nine years prior to the creation of the bureau, Pavel Sukhoi , an aerospace engineer , took over team no. 4 of the CAHI's AGOS aviation, flying boat aviation and aircraft prototype engineering facility. Under Sukhoi's leadership, the team of the future design bureau started to take shape. The team, under the Tupolev OKB , produced experimental fighters such as the I-3, I-14, and

210-408: A branch of IRKUT Corporation, changing its name to Regional aircraft. This is stated on the company's website. "Within the implementation of the strategy uniting civil aircraft companies into one Civil Aviation Division JSC “SCA” has been integrated into Irkut Corporation starting from February 17, 2020. The decision was adopted by JSC “SCA” Shareholders on June 27, 2019. Regional Aircraft – Branch of

315-584: 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

420-470: 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

525-435: 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

630-774: A deputy of the Supreme Soviet of the USSR . Sukhoi died on 15 September 1975 at the Barvikha sanatorium in Moscow, and was buried in the Novodevichy Cemetery . The last fighter Sukhoi designed was the T-10 ( Su-27 ) but he did not live to see it fly. Jet fighter Fighter aircraft (early on also pursuit aircraft ) are military aircraft designed primarily for air-to-air combat . In military conflict,

735-443: 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

840-552: 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

945-664: 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

1050-538: A new company named United Aircraft Corporation in February 2006. Mikoyan and Sukhoi were placed within the same operating unit. In September 2007, Sukhoi launched its first modern commercial regional airliner —the Superjet 100 (SSJ 100), a 78 to 98 seater, built by Sukhoi. It was unveiled at Komsomolsk-on-Amur . The maiden flight was made on May 19, 2008. In March 2008, Sukhoi was selected to design and produce

1155-431: 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

1260-550: 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

1365-638: 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

1470-576: A resolution to reopen institutions of higher education in Russia. Sukhoi returned to his studies at BMSTU and graduated in 1925 with his thesis titles Single-engined Pursuit Aircraft of 300 hp under the direction of aeronautics pioneer Andrei Tupolev . In March 1925, Sukhoi started working as an engineer and designer with the Central Aerohydrodynamic Institute (TsAGI) and Moscow Factory Number 156 under Tupolev. During

1575-742: 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

1680-643: 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

1785-420: 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

1890-402: 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

1995-549: 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

2100-1060: Is composed of the JSC Sukhoi Design Bureau and the JSC Sukhoi Civil Aircraft, located in Moscow , the Novosibirsk Aircraft Production Association (NAPA), located in Novosibirsk , and the Komsomolsk-on-Amur Aircraft Production Association (KnAAPO), located in Komsomolsk-on-Amur . Sukhoi is headquartered in Moscow. Finmeccanica (since 2017, Leonardo ) owns 25% + 1 share of Sukhoi's civil division. The Russian government merged Sukhoi with Mikoyan , Ilyushin , Irkut , Tupolev , and Yakovlev as

2205-623: 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

2310-729: The Belarusian State University of Transport . In 1915, Sukhoi was admitted to the Imperial Moscow Technical School in Moscow after passing the entrance exams . However, Sukhoi's studies were interrupted when he was drafted into the Imperial Russian Army following the escalation of World War I . Sukhoi attended warrant officer training assigned to the artillery of the Russian Western Front . Sukhoi

2415-708: The Cold War , including the supersonic Su-7 , which became the main Soviet fighter-bomber of the 1960s, and interceptors Su-9 and Su-15 , which formed the backbone of the Soviet Air Defence Forces . Sukhoi also pioneered variable-sweep wing aircraft, such as the Su-17 and Su-24 . Sukhoi also started a number of projects that were not developed, including the ambitious Mach-3-capable Sukhoi T-3 attack aircraft . From 1958 to 1974, Sukhoi served as

2520-562: 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

2625-631: The Eastern Front of World War II . In September 1939, Sukhoi founded an independent engineering and design department named Sukhoi Design Bureau (OKB Sukhoi) located in Kharkiv . Sukhoi was not satisfied with the geographical location of the OKB, which was isolated from the scientific centers of Moscow. Sukhoi insisted that the OKB should relocate to an aerodrome in Moscow Oblast , and by

2730-593: The Il-114 passenger turboprop and modernized Ilyushin Il-96 -400 widebody will stay with Ilyushin . The new commercial division will also include the Yakovlev Design Bureau , avionics specialist UAC—Integration Center and composite manufacturer AeroComposit. Sukhoi Civil Aircraft Company (SCAC), a developer and manufacturer of SuperJet aircraft, ceased operations as an independent legal entity and became

2835-806: The Ilyushin Il-2 . The government, however later chose the Il-2 over the Su-6, but rewarded Sukhoi a Stalin Prize of the 1st Level for its development in 1943. Sukhoi and this team later focused on development of variants of the Su-2, the prototype cannon-armed Sukhoi Su-1 (Su-3) fighter, as well as the Sukhoi Su-8 , which to serve as a long-range ground-attack aircraft for the Soviet Air Forces , but

2940-585: 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,

3045-510: 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

3150-588: 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

3255-543: The Soviet Union 's first booster aircraft control system, landing braking parachute, catapult ejection seat with telescopic trolley, and a jettisonable nose with a pressurized cockpit. From 1949, Sukhoi fell out of Stalin's favor and in a government resolution, the Sukhoi Design Bureau was scrapped, and Sukhoi was forced to return to work under Andrei Tupolev , this time as Deputy Chief Designer. In 1953,

3360-792: The Stangensteuerung in German, for "pushrod control system") devised by the engineers of Anthony Fokker 's firm was the first system to enter service. It would usher in what the British called the " Fokker scourge " and a period of air superiority for the German forces, making the Fokker Eindecker monoplane a feared name over the Western Front , despite its being an adaptation of an obsolete pre-war French Morane-Saulnier racing airplane, with poor flight characteristics and

Sukhoi and his team also used the Tupolev Tu-2 bomber to develop and produce the trainer bomber UTB-2, worked on passenger and troop-carrying aircraft, the jet fighter Sukhoi Su-14, and a number of other aircraft. From 1945 to 1950, Sukhoi and his team also developed

3570-567: The carbon fiber composite wings for Irkut's MC-21 's airframe. Sukhoi is also working on what is to be Russia's fifth-generation stealth fighter , the Sukhoi Su-57 . The maiden flight took place on the 29 January 2010. As of January 2015, Sukhoi is working on a family of the regional airliner: the Sukhoi Superjet 100 , such as the jet airliner Superjet 130 , which would have a seating capacity of 130 to 145 seats, and to bridge

3675-542: The design bureau standalone status and relocation of the bureau to the Production Aircraft Plant No. 135 in Kharkov , Ukrainian SSR . However, Sukhoi was not satisfied with its location, since it was isolated from the scientific pole of Moscow . Sukhoi later relocated the bureau to the aerodrome of Podmoskovye in Moscow, completing half of the relocation by 1940. Sukhoi encountered another issue:

3780-668: 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

3885-639: 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

3990-731: The DIP, a record-breaking RD aircraft, the Tupolev ANT-25 , flown by famous Soviet aviators , Valery Chkalov and Mikhail Gromov , and the long-range bombers such as the Tupolev TB-1 and the Tupolev TB-3 . In 1936, Joseph Stalin , leader of the Soviet Union , issued a requirement for a multi-role combat aircraft . As a result, Sukhoi and his team developed the BB-1, a reconnaissance aircraft and light bomber in 1937. The BB-1

4095-483: The German flying services during the course of that year. 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

4200-618: 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

4305-504: The Irkut Corporation shall resume the continuity of business in the areas of development, production and aftersales support of the aircraft," - it is stated on corporate website in the section "Company". In June 2023 patents for a new design of a single engine Su-75 stealth fighter were filed, given the codename checkmate the design work has taken 3 years and test aircraft are under construction.

4410-414: 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

4515-642: 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

4620-509: 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

4725-420: 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

4830-419: The Soviet Polikarpov I-16 . The later German design was earlier in its design cycle, and had more room for development and the lessons learned led to greatly improved models in World War II. The Russians failed to keep up and despite newer models coming into service, I-16s remaining the most common Soviet front-line fighter into 1942 despite being outclassed by the improved Bf 109s in World War II. For their part,

4935-419: The Soviet war effort as part of Lend-Lease , with the Bell P-39 Airacobra proving particularly effective in the lower-altitude combat typical of the Eastern Front. The Soviets were also helped indirectly by the American and British bombing campaigns, which forced the Luftwaffe to shift many of its fighters away from the Eastern Front in defense against these raids. The Soviets increasingly were able to challenge

5040-451: The US for pursuit (e.g. Curtiss P-40 Warhawk ), a translation of the French "C" ( Dewoitine D.520 C.1 ) for Chasseur while in Russia "I" was used for Istrebitel , or exterminator ( Polikarpov I-16 ). As fighter types have proliferated, the air superiority fighter emerged as a specific role at the pinnacle of speed, maneuverability, and air-to-air weapon systems – able to hold its own against all other fighters and establish its dominance in

5145-529: 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

5250-440: The ability to gather information by reconnaissance over the battlefield. 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

5355-409: The advantages of fighting above Britain's home territory allowed the RAF to deny Germany air superiority, saving the UK from possible German invasion and dealing the Axis a major defeat early in the Second World War. On the Eastern Front , Soviet fighter forces were overwhelmed during the opening phases of Operation Barbarossa . This was a result of the tactical surprise at the outset of the campaign,

5460-534: The airspace over armies became increasingly important, all of the major powers developed fighters to support their military operations. 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

5565-405: The annual general meeting of shareholders of the PJSC Sukhoi Company, with the election recently on June 28, 2017. Notes Bibliography Pavel Sukhoi Pavel Osipovich Sukhoi ( Russian : Па́вел О́сипович Сухо́й ; Belarusian : Па́вел Во́сіпавіч Сухі́ , Paviel Vosipavič Suchi ; 22 July 1895 – 15 September 1975) was a Soviet aerospace engineer and aircraft designer known as

5670-433: The basis for an effective "fighter" in the modern sense of the word. It was based on small fast aircraft developed before the war for air racing such with the Gordon Bennett Cup and Schneider Trophy . The military scout airplane was not expected to carry serious armament, but rather to rely on speed to "scout" a location, and return quickly to report, making it a flying horse. British scout aircraft, in this sense, included

5775-414: The bombers and enemy attackers as a protective shield. The primary requirement was for long range, with several heavy fighters given the role. 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

5880-457: The bureau had no production line in Moscow, thus making it useless as Sukhoi had nothing to do. During the German invasion of the Soviet Union in World War II , the Su-2 needed a successor as it was proved obsolete and under-armed against German aircraft, with 222 aircraft destroyed in total. Sukhoi and his bureau designed a two-seat armored ground-attack aircraft , the Sukhoi Su-6 , considered in some terms to be superior to its competitor,

5985-539: The company. The progress made by the new branch would lead to the development of the utility aircraft, the Su-80 , and the agricultural aircraft, the Su-38 , less than a decade later. In 1996, the government re-gathered the major part of them forming Sukhoi Aviation Military Industrial Combine ( Sukhoi AIMC ). In parallel, other entities, including Ulan Ude factory, Tbilisi factory, Belarus and Ukraine factories, established alternate transnational Sukhoi Attack Aircraft (planning to produce e.g. Su-25 TM). The Sukhoi AIMC

6090-539: 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

6195-550: 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

6300-463: 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

6405-513: 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

6510-412: The first half of 1940 the relocation was completed. By the winter of 1942, Sukhoi encountered another problem: since he had no production line of his own, he had nothing to do. Sukhoi had developed a new ground-attack aircraft , the Su-6 , but Soviet leader Joseph Stalin decided that this plane should not be put into production, favouring production of the Ilyushin Il-2 . In the postwar years, Sukhoi

6615-407: The following years, Sukhoi designed and constructed aircraft including the record-setting Tupolev ANT-25 and the TB-1 and TB-3 heavy bombers . In 1932, Sukhoi was appointed head of the engineering and design department of TsAGI, and in 1938 he was promoted to head of the department of design. Sukhoi also developed a multi-purpose light aircraft, the Su-2 , which saw service in the early years of

6720-445: The founder of the Sukhoi Design Bureau . Sukhoi designed military aircraft with Tupolev and Sukhoi for 50 years, and produced many notable Soviet planes such as the Sukhoi Su-7 , Su-17 , and Su-24 . His planes set two altitude world records (1959, 1962) and two world speed records (1960, 1962). Sukhoi was honored in the Soviet Union as a Hero of Socialist Labor and awarded the Order of Lenin three times. Pavel Osipovich Sukhoi

6825-426: The gap of Russian aircraft between the Superjet Stretch and the Irkut MC-21 . At the end of November 2018, United Aircraft Corporation transferred SCAC from Sukhoi to the Irkut Corporation, to become UAC's airliner division, as Leonardo S.p.A. pulled out in early 2017 because of Superjet's poor financial performance. Irkut will manage the Superjet 100 , the MC-21 and the Russo-Chinese CR929 widebody, but

6930-406: 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

7035-433: 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

7140-440: 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

7245-420: 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

7350-401: 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

7455-410: 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

7560-495: 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

7665-607: 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

7770-488: 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

7875-451: 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

7980-487: 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

8085-433: 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

8190-530: 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

8295-451: 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

8400-410: 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

8505-575: 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

8610-461: 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

8715-458: 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

8820-426: 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,

8925-421: 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

9030-502: The school for the children of railway workers headed by his father. Around this time, Sukhoi contracted typhus and then scarlet fever which significantly affected his ability to speak, and he developed a reputation as a quiet person for the remainder of his life. In 1920, Sukhoi was finally demobilized from the army because of his health-related problems, and the government of the Russian Soviet Republic issued

9135-532: 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

9240-417: 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

9345-408: 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

9450-420: 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

9555-485: 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

9660-464: 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

9765-670: 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

9870-478: 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

9975-506: 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

10080-427: The year of Stalin's death, he was permitted to re-establish his own Sukhoi Design Bureau, set up with new production facilities. After the collapse of the Soviet Union , each of the multitude of bureaus and factories producing Sukhoi components was privatized independently. In the early 1990s, Sukhoi started to diversify its products and initiated Sukhoi Civil Aircraft to create a line of civil aviation projects for

10185-419: Was among the first Soviet aircraft designers who led the work on jet aircraft , creating several experimental jet fighters. From 1949, Sukhoi fell out of Stalin's favour and was forced to return to work under Tupolev, this time as Deputy Chief Designer. In 1953, the year of Stalin's death, Sukhoi was permitted to re-establish his own Sukhoi Design Bureau. Sukhoi produced several major serial combat aircraft during

10290-648: Was approved and under a July 29, 1939 government resolution, the Sukhoi OKB , designated as OKB-51, also known as the Sukhoi Design Bureau, was developed in order to set up production for the aircraft. The BB-1 was introduced and later adopted by the Soviet Air Forces in the same year. A year later, the BB-1 was later designated the Sukhoi Su-2 . A total of 910 Su-2 aircraft were built. The resolution also made Sukhoi chief designer, gave Sukhoi's team of

10395-570: Was born 22 July 1895 in Hlybokaye , Vilna Governorate of the Russian Empire , to ethnic Belarusian parents of peasant background. He had five sisters and no brothers. In 1900, Sukhoi's family moved to Gomel when his father, Osip Andreevich Sukhoi, got a job as a teacher at a school for the children of railway workers. From 1905 to 1914, Sukhoi attended the gymnasium in Gomel, now

10500-610: Was in the Russian Army when it collapsed after the October Revolution in 1917, returning to Moscow to find his university was closed. Instead, Sukhoi returned to Gomel to live with his parents and was offered a place as a mathematics teacher in the small town of Luninets near Brest-Litovsk . In 1919, Sukhoi fled to Gomel as Polish troops advanced on Luninets during the Polish–Soviet War , and began teaching at

10605-570: Was later discarded as the Soviet Union was winning the Eastern Front . After the war, Sukhoi and his team were among the first Soviet aircraft designers who led the work on jet aircraft , creating several experimental jet fighters . Sukhoi started developing two mixed-power fighters, the Sukhoi Su-5 and a modification of the Sukhoi Su-6 named Su-7 before 1945. At the start of 1945, the design bureau started working on jet fighters such as

10710-420: 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

10815-485: 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

10920-508: 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

11025-467: Was seen emerging from a warehouse located on the site of Sukhoi Design Bureau's headquarters in Moscow . On 14 June 2024, another fire, this time more serious, broke out in a different building at the same site in Moscow, collapsing the roof of the latter. An area of some 800 square meters was destroyed. However officials said that the building wasn't in use at the time. Over 70 firefighters and 25 units were used to put out this fire.
