How the Sukhoi Design Bureau Overtook the Great Mikoyan Design Bureau

Airpowerasia, Anil Chopra, Russia, How the Sukhoi Design Bureau Overtook the Great Mikoyan Design Bureau

During the Cold War, the Mikoyan-Gurevich (MiG) design bureau held a monopoly on frontline fighters (like the MiG-21 and MiG-29), while the Sukhoi Design Bureau (Sukhoi) specialized in strike aircraft. Sukhoi seems to have surpassed the legendary MiG pack due to the massive success of the Su-27Flanker” family. Mikoyan’s financial struggles following the Soviet collapse led the Russian government to consolidate the two entities under the United Aircraft Corporation (UAC). The heavy air-superiority Su-27 fighter, initially designed in the 1970s, was incredibly versatile, boasting a massive payload capacity, incredible manoeuvrability, and a long combat radius. It proved to be a highly adaptable platform, allowing Sukhoi to develop highly successful variants such as the Su-30, Su-35, and Su-34. Meanwhile, MiG‘s lighter MiG-29 lacked the space and payload for similar evolutionary upgrades.

When the Soviet Union dissolved, domestic funding for military research and development dried up, forcing design bureaus to rely on the international market. The Su-27 series, particularly the export variants sold to major buyers like India and China, generated substantial revenue. Sukhoi used these profits to fund next-generation developments internally. MiG heavily promoted the lightweight MiG-29 upgrades and the MiG-35, but it was limited by its shorter range and maintenance issues. When the 1.44 MFI (Multifunctional Frontline Fighter) stealth programme failed, MiG lost its edge as Russia‘s premier advanced fighter developer.

By 2006, the Russian government moved to save its flailing aerospace industry by merging the major design bureaus, including Sukhoi, MiG, Tupolev, and Yakovlev, into a single state-owned conglomerate called the UAC. Under this centralized management, Sukhoi effectively absorbed MiG‘s design philosophies and took the lead on all major new war-bird contracts, including Russia‘s fifth-generation stealth fighter, the Su-57. MiG had built its legendary reputation on small, fast, and light interceptors. While this was a winning strategy during the height of the Cold War, modern air combat demands long-range endurance, heavy payload capacity, including long-range ones, and extensive space for advanced avionics and radar systems. Sukhoi’s heavy-fighter philosophy proved far better suited to the demands of modern and future aerial warfare.

Mikoyan Design Bureau

The Mikoyan Design Bureau (MiG) was a premier Russian aerospace company and major designer of military jet aircraft. Founded in 1939 by Artem Mikoyan and Mikhail Gurevich, from whose names the design bureau’s title was derived. It has produced over 15,000 aircraft and is globally renowned for its highly agile fighters and interceptors. It began as an independent experimental design bureau (OKB-155) in Moscow. MiG fighters became a staple of the Soviet Air Force and the global Allied nations. They frequently engaged American forces, most notably during the Korean War and Vietnam War. The iconic MiG-15 was one of the world’s first successful swept-wing jet fighters, surprising Western forces with its performance in the Korean War. The United States had to rush the North American F-86 Sabre into combat to counter the MiG-15 that outperformed the Allied straight-wing jets. The swept-wing Sabre provided technical parity, leading to intense aerial battles in a region known as MiG Alley.

The MiG-17 is a direct, advanced development of the MiG-15. A total of 10,900 MiG-17 aircraft were built. The Soviet Union (6,000) stopped production in 1958. China (Shenyang J-5) and Poland (Lim-5 / Lim-6) produced significant numbers for the Warsaw Pact and exports. A total of 6,672 MiG-19 twin-engine jets and licensed variants were built globally. The Soviet Union (2,172) and China (Shenyang J-6) built over 4,500 under license.

The MiG-21 was the most-produced supersonic jet aircraft in aviation history, serving in over 60 countries. The aircraft reached a peak average production rate of approximately 300 units per year across its multiple manufacturing facilities during the height of the Cold War. Both India and China licensed-built or reverse-engineered the Soviet-designed MiG-21, producing over 3,000 aircraft combined. India assembled various MiG-21 versions locally, becoming the largest foreign operator until its fleet’s retirement in 2025. China reverse-engineered it to create the Chengdu J-7, which saw extensive domestic use and global export.

Concerned about heavy losses against MiG-21s in Vietnam, the Americans set up the United States Navy Strike Fighter Tactics Instructor program, universally known as TOPGUN and also called the “MiG-killing” school. The most significant aerial clashes between the Indian Air Force‘s (IAF) MiG-21 and the Pakistani Air Force‘s (PAF) F-104 Starfighter occurred during the 1971 Indo-Pakistani War. During these engagements, the agile MiG-21FL decisively outperformed the F-104, shooting down several Starfighters and earning a reputation that prompted Pakistan to eventually retire the F-104.

The MiG-23 and MiG-27 family (NATO: “Flogger”) was a legendary line of Soviet-era, variable-sweep “swing-wing” aircraft. While the MiG-23 was built as an air-superiority interceptor, the MiG-27 was heavily redesigned as a dedicated ground-attack aircraft, distinguished by its sloped “duck nose” and heavier armour. A combined total of over 6,000 aircraft was built. Active flying fleets were primarily maintained by former Soviet allies, Middle Eastern states, and India. The MiG-27 saw limited use outside the Soviet Union, with India acting as the largest export operator. Other MiG-27 operators were Kazakhstan and Ukraine.

The MiG-25 (Foxbat) was a supersonic interceptor and reconnaissance aircraft. Known for its blistering speed of Mach 2.83, it was designed primarily to outrun and intercept high-altitude American bombers and spy planes. The Foxbat remains one of the fastest military aircraft ever to enter service. Capable of reaching Mach 3.2, though this caused severe engine damage. Built primarily of heavy stainless steel and nickel alloys rather than titanium, enabling field repairs with standard welding equipment. It was powered by two massive Tumansky R-15B-300 turbojet engines equipped with enormous afterburners. Typically, it carried four massive radar-guided or heat-seeking air-to-air missiles. When the MiG-25 was first unveiled in 1967, its large wings and massive air intakes led Western intelligence to believe it was a highly agile dogfighter. This perception triggered the United States to accelerate its own next-generation fighter programmes, which ultimately birthed the F-15 Eagle. Its true capabilities were revealed to the West in September 1976, when Soviet pilot Viktor Belenko defected, flying his MiG-25 to Hakodate, Japan. Intelligence officials discovered that the aircraft was specialized exclusively for high-speed intercept and reconnaissance. Its heavy steel airframe limited manoeuvrability, and it was primarily built to destroy targets at high altitudes rather than engage in close-quarters dogfights. It was developed to counter the threat of Mach 3-capable American bombers (like the XB-70) and reconnaissance planes, and was engineered to get high and fast quickly. The main operators were the Soviet Union, Algeria (36 aircraft), Syria, Libya, Iraq, India (MiG-25R/RB reconnaissance variants for strategic aerial photography and intelligence missions), Bulgaria, and Turkmenistan.

The MiG-29Fulcrum” is a legendary Soviet-era twin-engine air superiority fighter. First introduced in 1983, it was designed alongside the larger Sukhoi Su-27 to counter advanced U.S. fighters like the F-15 Eagle and F-16 Fighting Falcon. Renowned for its extreme agility and close-range dogfighting capabilities, it has been widely exported and remains in service globally. This 4th-generation air superiority and multirole fighter includes the MiG-29S/SMT and early upgrades introducing beyond-visual-range (BVR) missile compatibility and improved avionics. The MiG-29K is a carrier-capable variant utilized by the Russian Navy and Indian Navy. The MiG-29UPG is an advanced, upgraded multirole variant customized heavily for the IAF. Over 1,600 MiG-29s were built between 1981 and 2019, and they remain in active service with more than 20 air forces globally.

The MiG-31Foxhound” is a heavy, all-weather supersonic interceptor developed as the replacement for the MiG-25Foxbat”, on which it is based and shares design elements. With a top speed of around 3,000 km/h, it continues to be operated by the Russian Aerospace Forces (VKS). The Russian Defence Ministry expects the MiG-31 to remain in service until at least 2030. The MiG-31K variant carries the Kh-47M2 Kinzhal conventional or nuclear warhead-capable air-launched ballistic missile. The MiG-31BM multirole version features upgraded avionics, a new multimode radar, hands-on-throttle-and-stick (HOTAS) controls, liquid crystal (LCD) colour multifunction displays (MFDs), and the ability to carry modern Russian weapons. The author of this article had to fly this variant in Russia in 1999. A total of 519 MiG-31s were built. Kazakhstan inherited its MiG-31s from the Soviet Union and used them up till 2023. Attempts to sell the same to India were not successful.

The MiG-35 is a modern 4.5-generation multirole upgrade of the base MiG-29 and is integrated into the state-owned United Aircraft Corporation (UAC), operating under the umbrella of Rostec. While still maintaining production, the design bureau has seen its market presence shift with rivals like Sukhoi taking lead roles in modern Russian aerospace. Potential buyers like India and Egypt have not followed up. Only around 10 have reportedly been built.

The Sukhoi Stable

The Sukhoi Design Bureau specialises in the design, construction, and testing of advanced military and civilian aircraft. Headquartered in Moscow, it was founded by Pavel Sukhoi in 1939 (beginning of WW II) and today operates as a core subsidiary of the state-owned UAC. The foundational aircraft was the Su-2 light ground-attack bomber that retired in 1944. It transitioned to the jet age in the 1950s and 60s with iconic supersonic fighters like the Su-7 and Su-17.

The Su-7Fitter” was a highly swept-wing ground-attack aircraft (1,847 built). The IAF used the Su-7 extensively in the 1971 war with Pakistan. It had six squadrons (140 aircraft), flew almost 1,500 offensive sorties during the war, and undertook the bulk of the daytime attack missions. The IAF managed to retain a very high operational tempo with its Su-7s, peaking at a sortie rate of six per pilot per day. Fourteen Su-7s were lost during the war, mostly due to anti-aircraft fire, but it was found that the aircraft had high survivability, being able to fly home safely despite receiving heavy damage.

The delta-wing, somewhat larger look-alike of the MiG-21, the Su-9 “Fishpot”, was flown only by the Soviet Union, with 1,150 built, and was retired in 1979. The Su-11 was a lesser-known variant of the Su-9, and only 108 were built. The Su-15Flagon” was a twin-jet supersonic interceptor. It entered service in 1965 and remained one of the front-line designs into the 1990s. The Su-15 was designed to replace the Su-11 and Su-9, as NATO introduced newer and more capable strategic bombers. The supersonic Su-15 had the performance needed to chase down high-subsonic aircraft like the B-52 and Vulcan, and the range to do so while those aircraft were still far from their targets. 1,290 were built and finally retired in 1996.

The Su-17Fitter” was a variable-sweep wing fighter-bomber developed from the Su-7. It was the first variable-sweep wing aircraft to enter Soviet service and featured updated avionics. Although the Su-17 was capable of carrying nuclear weapons, it was used in roles ranging from close-air support to ground attack. The aircraft also had variants which were designed for export,t such as the Sukhoi Su-22 and the less popular Su-20. 2,867 were produced from 1967 to 1990, and it was operated by the Soviet Union and other members of the Warsaw Pact, countries in the Arab world, Angola, and Peru.

The Su-24Fencer” is a supersonic, all-weather tactical bomber. The aircraft has a variable-sweep wing, twin engines, and a side-by-side seating arrangement for its crew of two. It was the first of the USSR‘s aircraft to carry an integrated digital navigation/attack system. The Su-24 first flew in 1967. It entered service in 1974 and production ceased in 1993. Over 1,400 were built. It remains in service with Russia, Iran, Ukraine, Algeria, and a few others. It has seen combat action in most of the wars since the Soviet–Afghan War (1988) and in more recent wars in Ukraine and the USA-Israel-Iran war.

The Su-25Frogfoot” is a subsonic, single-seat, twin-engine jet designed for dedicated close air support. It had a somewhat similar mission to that of the American Fairchild Republic A-10 Thunderbolt IIWarthog”. The aircraft went into series production in 1978. Some aircraft were upgraded to the Su-25SM standard in 2012. The Su-25 and the Su-34 were the only armoured, fixed-wing aircraft in production in 2007. Su-25s are in service with Russia, other CIS members, and export customers. Production ended in 2010. The Su-25 has seen combat in several conflicts f, from the Soviet–Afghan War, and on both sides in the Russo-Ukrainian war. Over 1,000 were built.

The Su-27Flanker” is a twin-engine supersonic super-manoeuvrable fighter intended as a direct competitor for the large U.S. fourth-generation jet fighters such as the Grumman F-14 Tomcat and McDonnell Douglas F-15 Eagle. 809 were built. With a 3,530-kilometre range, heavy aircraft ordnance, sophisticated avionics, and high manoeuvrability, it was designed for air superiority missions, and subsequent variants are able to perform almost all aerial warfare operations. It was designed with the Mikoyan MiG-29 as its complement. It entered service in 1985. The primary role was long-range air defence against American bombers such as the Rockwell B-1B Lancer, and flying long-range fighter escort for Soviet heavy Tupolev bombers. The Su-27 was developed into a family of aircraft that includes the Su-30, the Su-33 (naval), Su-34, and Su-35. The Shenyang J-11 (440 built) is a Chinese license-built version of the Su-27.

The Su-33Flanker-D” is a carrier-based multirole fighter derived from the Su-27 (initially known as Su-27K). Only 35 aircraft were produced. Attempted sales to China and India were unsuccessful. The Russian Navy ordered the MiG-29K as a replacement in 2009.

The Su-30 “Flanker-C/G/H” is a multirole fighter evolved from the Su-27UB (two-seater). Initially, the Su-27PU heavy interceptor was developed, and later renamed as Su-30 in 1996, around the time India signed the contract. The Su-30MKK and the Su-30MK2 were designed for and sold to China, and laterto Indonesia, Uganda, Venezuela, and Vietnam. The Chinese chose an older but lighter radar so the canards could be omitted in return for increased payload. India chose to design and further develop the multirole Su-30MKI. Along with its ground-attack capabilities, the series added features for the air-superiority role, such as canards, thrust-vectoring, and a long-range phased-array radar. Su-30MKM, Su-30MKA, and Su-30SM were developed for Malaysia, Algeria, and Russia, respectively. Nearly 1,050 Su-30 variants were built.

The Su-57Felon” (T-50) is a twin-engine stealth multirole fighter and a product of the PAK FA program,e which was initiated in 1999. It is the first stealth aircraft in Russian military service. The Su-57 incorporates stealth, super-manoeuvrability, super-cruise, integrated avionics, and a large payload capacity. It will be nuclear-capable using a forthcoming missile similar to the Kinzhal. The aircraft is expected to succeed the MiG-29 and Su-27, and has an export market. The prototype aircraft flew in 2010, but the programme experienced a protracted development due to various structural and technical issues that emerged during trials, including the destruction of the first production aircraft in a crash before its delivery. The aircraft was first operationally deployed in Syria. It formally entered the Russian Aerospace Forces (VKS) in December 2020. It has reportedly been sporadically used in the Ukraine War since 2022. Nearly 45 aircraft have been built to date. Russia has offered to make the aircraft ” Made in India” with full technology transfer.

The Su-75Checkmate”, also designated as the Light Tactical Aircraft (LTA), is a single-engine, stealth fighter aircraft under development. The first flight of this relatively smaller and low-cost aircraft is scheduled for late 2026.

The Sukhoi Design Bureau is recognized globally as a leader in aerospace engineering. The bureau has manufactured over 10,000 aircraft, with thousands exported to countries such as India, China, and Vietnam. Sukhoi‘s civil division, in September 2007, launched its first modern commercial regional airliner, the Superjet 100 (SSJ 100), a 78- to 98-seater. The Superjet 130 would have a seating capacity of 130 to 145 seats.

Sukhoi vs Mikoyan

MiG did build some great aircraft – MiG-15, MiG-17, MiG-19, MiG-21, MiG-25, MiG-29, and MiG-31. The MiG-23, too,o, was a good aircraft with superb supersonic performance (better than the F-15A / F-16A). Its only disadvantage was complexity, but its performance reflects the engineering capability of Mikoyan. For long, ng the MiG designs were in the lead. The conventional controls of the MiG-29 outperformed the fly-by-wire F-16 and Mirage-2000 on many counts.

Although different design bureaux competed with one another, MiG was the one that usually ended up developing the frontal aviation fighters, while Sukhoi usually did the same with strike planes. Being forced to drastically cut its defence budget, Russia decided to retire all single-engined planes and, more generally speaking, to abandon the same concept of the frontal fighter, i.e., small, simple, with limited autonomy, and available in high numbers.

Trying to transition, around 1998, from the MiG-29 (and its variants) to the Mikoyan-1.44 did not succeed. Project 1.44 was an experimental Russian fifth-generation air superiority fighter. Conceived as the Soviet answer to the American F-22 Raptor, the programme suffered from severe post-Cold War funding shortages and was ultimately cancelled shortly after its 18-minute maiden test flight on February 29, 2000. The technological data, however, contributed to Russia‘s ongoing fifth-generation programmes. It featured a distinct delta-wing configuration with canards and twin outward-leaning vertical stabilizers, and was powered by two Lyulka AL-41F afterburning turbofan engines.

From the Su-27 onwards, Sukhoi had the clear advantage. The MiG-31, maybe the MiG-31M, was the last truly great plane from Mikoyan. The end of the Cold War had its own dynamics. The Russian economy was in the doldrums. Russia’s internal demand had dropped. Su-27 variants were greatly propped up by the Chinese and Indian air power demands. The MiG-35 was essentially a repackaged MiG-29. Mikoyan ran out of funding. No major design came out after the year 2000.

Sukhoi got lucky with international markets. The Americans weren’t very willing to sell F-15 Eagles, and the Flanker was the only other option. Those international contracts allowed Sukhoi to remain afloat and retain know-how and a core of qualified personnel. The merger into the UAC resulted in the dominance of Sukhoi, which had clear orders. On the other hand, when the Russian military budgets shrank after 1990, rather than laying off workers, MiG decided to keep building MiG-29 airframes to keep everybody employed, just hoping that somebody would come along and buy them. They still have some MiG-29 airframes.

The Mikoyan and Sukhoi platforms represent two distinct Soviet-era aerospace philosophies. Mikoyan (MiG) designs prioritize lightweight, low-cost “frontline” fighters built for rapid interception, high speed, and ease of maintenance. Conversely, Sukhoi platforms are larger, robust air-superiority aircraft designed for heavy weapon payloads, extreme manoeuvrability, and extended combat ranges.

The highly decorated designer Artem Ivanovich Mikoyan (1905–1970) and later Rostislav Belyakov (1919–2014) were men of very high stature and could not be replaced by such equivalents. It is sunset time for the Mikoyan legacy. Pavel Sukhoi (1895–1975) was the legendary aerospace engineer and founder of the Sukhoi Design Bureau. Following his tenure, notable successors who directed the bureau include Mikhail Simonov (architect of the Su-27) and Mikhail Strelets (who led the Su-57 programme). Their stature was less than their MiG counterparts. If one were to say that it was a 5,000-kilometre race, MiG led for the first 3,500 kilometres till Sukhoi overtook and went ahead.
