MiG-29 fighter


Development
In 1969 the Soviet Union learned of the U.S. Air Force's "F-X" program, which resulted in the F-15 Eagle. The Soviet leadership soon realized that the new American fighter would represent a serious technological advantage over existing Soviet fighters. What was needed was a better-balanced fighter with both good agility and sophisticated systems. In response, the Soviet General Staff issued a requirement for a Perspektivnyy Frontovoy Istrebitel (PFI, roughly "Advanced Frontline Fighter", literally "Perspective Frontline Fighter"). Specifications were extremely ambitious, calling for long range, good short-field performance (including the ability to use austere runways), excellent agility, Mach 2+ speed, and heavy armament. The aerodynamic design for the new aircraft was largely carried out by TsAGI in collaboration with the Sukhoi design bureau. (This would become the Sukhoi Su-27.)

However, in 1971 the Soviets determined the PFI aircraft would be too expensive to procure in the quantities needed, and divided the requirement into the TPFI (Tyazhyolyy Perspektivnyy Frontovoy Istrebitel, "Heavy Advanced Tactical Fighter") and the LPFI (Lyogkiy Perspektivnyy Frontovoy Istrebitel, "Lightweight Advanced Tactical Fighter") programs, the latter paralleling the contemporary USAF decision that led to the "Lightweight Fighter" program and the F-16 Fighting Falcon and YF-17 Cobra. The heavy fighter remained with Sukhoi, resulting in the Sukhoi Su-27, while the lightweight fighter went to Mikoyan. Detailed design work on the resultant Product 9, designated MiG-29A, began in 1974, with the first flight taking place on 6 October 1977. The pre-production aircraft was first spotted by United States reconnaissance satellites in November of that year; it was dubbed Ram-L because it was observed at the Zhukovsky flight test center near the town of Ramenskoye. Early Western speculations suggested that the Ram-L was very similar in appearance to the YF-17 Cobra and powered by afterburning Tumansky R-25 turbojets.

State acceptance trials were completed in 1984, and deliveries began the same year to the Soviet Frontal Aviation.

The workload split between TPFI and LPFI became more apparent as the MiG-29 filtered into front line service with the VVS in the mid-1980s. While the heavy, long range Su-27 was tasked with the more exotic and dangerous role of deep air-to-air sweeps of NATO high-value assets, the smaller MiG-29 directly replaced the MiG-23 in the frontal aviation role. The MiG-29 was positioned relatively close to the front lines, tasked with providing local air superiority to advancing Soviet motorized army units. Rugged landing gear and protective intake grates meant the MiG-29 could operate from the damaged or under-prepared airstrips Soviet war planners expected to encounter during a rapid armored advance. The MiG-29 was also tasked with escort duties for local strike and interdiction air packages, protecting vulnerable ground attack aircraft from NATO fighters such as the F-15 and F-16. Frontal aviation MiG-29s would ensure Soviet ground forces could operate under a safe air umbrella, moving forward with the troops as they advanced.


MiG-29UB trainerIn the West, the new fighter was given the NATO reporting name "Fulcrum-A" because the pre-production MiG-29A, which should have logically received this designation, remained unknown in the West at that time. The MiG-29B was widely exported in downgraded versions known as MiG-29B 9-12A and MiG-29B 9-12B (for Warsaw Pact and non-Warsaw Pact nations, respectively), with less capable avionics and no capability for delivering nuclear weapons. Total production was about 840 aircraft.

Refined versions of the MiG-29 with improved avionics were fielded by the Soviet Union, but Mikoyan’s multi-role variants, including a carrier-based version designated MiG-29K, were never produced in large numbers. In the post-Soviet era, MiG-29 development was influenced by the Mikoyan bureau's apparent lack of political clout compared to rival Sukhoi. Some more advanced versions are still being pursued for export, and updates of existing Russian aircraft are likely. New versions of the plane called MiG-29SMT and MiG-29M1/M2 are being developed. Furthermore, development of a carrier version, the MiG-29K, has been resumed for the Indian Navy's INS Vikramaditya aircraft carrier (formerly the Russian aircraft carrier Admiral Gorshkov). This version was originally meant for Soviet service onboard the Admiral Kuznetsov, but the bigger Sukhoi Su-33 was preferred instead.

The Soviet Union did not assign official names to most of its aircraft, although nicknames were common. Unusually, some Soviet pilots found the MiG-29’s NATO reporting name, Fulcrum, to be a flattering description of the aircraft’s intended purpose, and it is sometimes unofficially used in Russian service.[2]
