A Soviet-built MiG-29 Fulcrum fighter flown by Major (MAJ) Peter Meisberger, from Germany`s (DEU) 73rd Fighter Wing (FW), Laage Air Base (AB), Germany, fires a radar guided AA-10 "Alamo" short-burn air-to-air missile at a QF-4 "Rhino" full-scale aerial target drone during a live-fire weapons training mission.

The R-27 (NATO name: AA-10 Alamo) is the medium-range air-to-air missile (MRAAM) developed by the Soviet Union/Russian Vympel Design Bureau in the early 1980s.

The Peoples Liberation Army Air Force received the missile as a part of the weapon package for the Su-27 fighters it purchased in the early 1990s.

Currently the PLAAF is equipped with at least three models: the semi-active radar-homing variant R-27R (AA-10A Alamo-A), the IR-homing variant R-27T (AA-10B Alamo-B), and the active radar-homing variant R-27AE (AA-10 Alamo-E).

The R-27 (AA-10) MRAAM family was introduced in the 1980s for the Soviet Unionís fourth-generation fighters such as the Su-27 and Mig-29, with a total of six variants developed with different seekers and engines.

The missile is also carried by improved versions of the MiG-21, MiG-23 and MiG-25. The missile was developed as a counter to the U.S. AIM-7F Sparrow MRAAM. China purchased unknown numbers of the R-27 missiles in several batches during the 1990s to arm its Su-27 fleet.


The R-27 missiles are intended to intercept and defeat aircraft and helicopters of all types, unmanned reconnaissance aircraft and cruise missiles under active enemy electronic jamming, counteractions and manoeuvring.

There are produced some variants of the AA-10 "Alamo" with two different seeker types - semi-active radar homing and infrared, and two types of engines - with standard and extended range engine.
