km/h and altitudes from 20 m to 27 km. Maximum target and launch aircraft altitude difference can
be up to 10 km. Maximum target G is eight. The combined launch of R-27 missiles with different
seeker variants increases the resistance to target counter measures. The R-27 family of missiles was
developed by the Vympel design bureau and went into operational service between 1987 and 1990.
Today, all versions of the MiG-29 and Su-27 fighters are equipped with these missiles.
