Supermaneuverability is the capability of fighter aircraft to execute tactical maneuvers that are not possible with purely aerodynamic techniques. Such maneuvers can involve controlled side-slipping or angles of attack beyond maximum lift.This capability was researched beginning in 1975 at the Langley Research Center in the United States, and eventually resulted in the development of the McDonnell Douglas F-15 STOL/MTD as a proof of concept aircraft. The Saab 35 Draken was another early aircraft with limited supermaneuverable capabilities. In 1983, the MiG-29 and in 1986, the Sukhoi Su-27 were deployed with this capability, which has since become standard in all of Russia's fourth- and fifth-generation aircraft. There has been some speculation, but the mechanism behind the supermaneuverability of the Russian-built aircraft has not been publicly disclosed. However, post-stall analyses have been increasingly used in recent years to advance maneuverability via the use of thrust vectoring engine nozzles.Russian emphasis on close-range slow-speed supermaneuverability runs counter to Western energy–maneuverability theory, which favors retaining kinetic energy to gain an increasingly better array of maneuvering options the longer an engagement endures. The USAF abandoned the concept as counter-productive to BVR engagements as the Cobra maneuver leaves the aircraft in a state of near-zero energy, having bled off most of its speed without gaining any compensating altitude in the process. Except in one-on-one engagements, this leaves the aircraft very vulnerable to both missile and gun attack by a wingman or other hostile, even if the initial threat overshoots the supermaneuvered aircraft.
