R-27T (RS-AA-10B Alamo) (reported)

The Vympel R-27 is a family of air-to-air missiles developed by the Soviet Union during the late Cold War-era. The R-27 is manufactured in infrared-homing/IR (R-27T, R-27ET) and semi-active radar homing/ SARH (R-27R, R-27ER) versions. The R-27 family missiles are produced by both Russian and Ukrainian manufacturers. The R-27 missile is carried by the Mikoyan MiG-29 and the Sukhoi Su-27, Su-30 and Su-35 family fighters. The R-27 missile is also license-produced in China, though the production license was bought from Ukraine instead of Russia. Plans to produce an active radar homing/ ARH version called the R-27EA were cancelled in 1989.

Developed by Vympel NPO in the Soviet Union and introduced in 1987, it served as a key weapon for Soviet and later Russian fighter aircraft.
