R-27 (air-to-air missile)

The Vympel R-27 missile (NATO reporting name AA-10 Alamo) is a medium-to-long-range air-to-air missile developed by the Soviet Union. It remains in service with the Russian Air Force and air forces of the Commonwealth of Independent States.

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.

Ethiopia and Eritrea

In the 1999 Eritrean-Ethiopian War, Eritrean MiG-29s fought Ethiopian Su-27s both piloted by Russian mercenaries. There were possibly as many as 24 R-27s fired by both sides. Only one R-27 fired by an Ethiopian Su-27 at an Eritrean MiG-29 proximity-fuzed near enough the MiG that the damaged aircraft eventually crashed on landing.


During the War in Donbass, the Ukrainian Air Force claimed that one of its Su-25 was shot down by a Russian Air Force MiG-29 using a R-27T on 16 July 2014. Russian officials denied any involvement.
