Lists on the subject

The R-27 ( DIA code : AA-10 , NATO code name : Alamo ) is a Russian , formerly Soviet , BVR - air-to-air guided missile for medium combat ranges.

development

A MiG-29 of the Bundeswehr fires an R-27 R (2003).

The R-27 was developed as a successor to the R-23 (AA-7 APEX). The latest generation of Soviet combat aircraft ( MiG-29 and Su-27 ) should also be equipped with it. Development at the manufacturer Wympel began in the Soviet Union in the mid-1970s. The first copies were delivered to the Soviet Air Force in 1985 . Then around 20 other countries procured the guided missile.

technology

The R-27 has a modular structure. An R-27 consists of the following modules: seeker head, steering unit and warhead as well as rocket motor. There are various versions of all modules that can be combined with one another. This resulted in different versions of the R-27: R-27R (NATO designation AA-10 "Alamo A") with semi-active radar steering and R-27T (AA-10 "Alamo B") with infrared steering.

These weapons were initially used with the aircraft types Mikojan-Gurewitsch MiG-29 and Sukhoi Su-27 (the Su-33 , Su-35 and the Jakowlew Jak-141 followed ). The further developments were initially characterized by a higher range: R-27ER (AA-10 "Alamo C") and R-27ET (AA-10 "Alamo D"). Fighter planes like the MiG-21 and MiG-23 can be retrofitted for use with the R-27.

Furthermore, the versions R-27P and R-27PE with passive radar search heads were created. These guided missiles are primarily used to combat radar surveillance aircraft ( AWACS ) and combat aircraft for electronic warfare.
