From Wikipedia, the free encyclopedia

The Bisnovat (later Molniya) R-4 (NATO reporting name AA-5 'Ash') was an early Soviet long-range air-to-air missile, initially designated K-80 or R-80.


Development of the R-4 began in 1959, entering operational service in 1963. It was used primarily on the Tupolev Tu-128 interceptor, matched to the Tu-128's RP-S Smerch ('Tornado') radar, although some reports suggested the MiG-25 sometimes carried it as well.

Like many Soviet weapons, it was made in both semi-active radar homing (R-4R) and infrared-homing (R-4T) versions. Standard Soviet doctrine was to fire the weapons in SARH/IR pairs to increase the odds of a hit. Target altitude was from 8 to 21 km, the missile could be fired from an aircraft flying 8 km below target.

In 1973 the weapon was modernized to R-4MR (SARH) / MT (IR) standard, with lower minimal target altitude (0.5-1 km), improved seeker performance and compatibility with the upgraded RP-SM Smerch radar.

The R-4 survived in limited service through at least the late 1980s, retiring along with the last Tu-128 aircraft after the end of the Cold War and the collapse of the Soviet Union.
