Vympel R-27 missile (with the NATO reporting name AA-10
Alamo) is a medium-to-long-range air-to-air missile developed by the
R-73Ae, R-27R1(AeR1), R-27T1(AeT1),
and Kh-59MAe at MACS, Zhukovski, 1999.
It remains in service with the Russian Air Force
and air forces of the
of Independent States
The R-27 is manufactured in infrared-homing
versions, in Russia and Ukraine. This missile is carried by the
and Sukhoi Su-27
fighters, and some of the
fighters were also adapted to carry it. The R-27 missile is
also license-produced in the PRC, though the production license was bought from the
country of Ukraine instead of
Russia. The Chinese-licensed production does not
include the active-radar-homing version, and China developed its
own active-radar version by adapting into it the active-radar
seeker of the Vympel R-77 missile, which
was sold to the PRC by Russia in the R-27

Eritrean-Ethiopian War from May 1998 to June 2000, R-27 missiles were used
in combat by both Ethiopian Su-27s and Eritrean MiG-29s.
if a number of aircraft from both sides were reported shot down, it
cannot be determined whether they were downed by R-27s, or
infrared-guided R-73s or R-60s, or by air-to-air gunfire.
