Military knowledge, News 30 July 2020

The Vympel R-27 missile, NATO codename AA-10 Alamo is a medium-to-long-range air-to-air missile developed by the Soviet Union.

The R-27 is manufactured in infrared-homing (R-27T), semi-active-radar-homing (R-27R), and active-radar-homing (R-27EA) versions, in both Russia and Ukraine.
The R-27 missile is carried by the Mikoyan MiG-29 and Sukhoi Su-27 fighters, and some of the later-model MiG-23MLD fighters have also been adapted to carry it. The R-27 missile is also license-produced in China, though the production license was bought from Ukraine instead of Russia.
