The Vympel R-27 (NATO reporting name AA-10 Alamo ) is a family of air-to-air missiles developed by the Soviet Union during the late Cold War-era. It remains in service with the Russian Aerospace Forces, air forces of the Commonwealth of Independent States and air forces of many other countries as the standard medium-range air-to-air missile despite the development of the more advanced R-77.
The R-27 is manufactured in infrared-homing (R-27T, R-27ET), [9] semi-active radar homing (R-27R, R-27ER), [10] and active-radar homing (R-27EA) [11] versions. R-27 family missiles are produced by both Russian and Ukrainian manufacturers. The R-27 missile is carried by the Mikoyan MiG-29 and Sukhoi Su-27 family fighters. The R-27 missile is also license-produced in China, [12] [13] though the production license was bought from Ukraine instead of Russia.
R-27R and ER variants can be used in any meteorological conditions. Launch can made at less than 5 g overload and less than 50 deg/s roll rate. [14] It is allowed to redesignate targets during flight, and can share target illumination with other aircraft.
R-27T and ET variants can be used out of cloudiness, at least 15 degrees away from the bearing of sun, and 4 degrees away from the bearing of moon and ground-based heat-contrasting conditions. In cases of maximum head-on range launches where lock-command cannot be utilized, missile can not be fired. Seeker must acquire target before launch. [15] On the combat operations section of the Su-27 manual, this is especially recommended for head-on usage for passive attacks at targets with 0 degrees approach angle (i.e. another fighter moving to intercept), leaving target unalerted to the incoming missile. [16] Launch can be made at 0 to 7 g, but limited to 6 g if roll induced slip is more than 2× diameter of the ball. [14]
Other variants:
In the 1999 Eritrean-Ethiopian War, Eritrean MiG-29s fought Ethiopian Su-27s both piloted by Russian mercenaries. [17] Only one R-27 fired by an Ethiopian Su-27 at an Eritrean MiG-29 proximity-fuzed near enough to the MiG that the damaged aircraft eventually crashed on landing.
During the war in Donbas, the Ukrainian Air Force claimed that one of its Su-25 was shot down by a Russian Aerospace Forces MiG-29 using a R-27T on 16 July 2014. [18] Russian officials denied any involvement. [19]
The R-27 was used by both sides during the 2022 Russian invasion of Ukraine. [20] [21]
During the Yemeni Civil War (2015–present) Houthis have used R-27T missiles modified to serve as surface to air missiles. A video released on January 7, 2018, also shows a modified R-27T hitting a Saudi led coalition fighter on a Forward looking infrared camera. Houthi sources claim to have downed a F-15. [22] [23] Rebels later released footage showing an aircraft wreck, however serial numbers on the wreckage suggested that the downed aircraft was a Panavia Tornado, also operated by Saudi forces. [24] On January 8, the Saudi Press Agency admitted the loss of an aircraft over Yemen, though it did not clarify whether it was a Tornado or an F-15, blaming the crash to 'a technical issue' and reporting that the pilots ejected and were recovered by friendly forces. [25]
On 21 March 2018, Houthi rebels released a video where they hit and possibly shot down a Saudi F-15 in Saada province. [26] In the video a R-27T air to air missile adapted for surface to air use was launched, appearing to have successfully hit a jet. As in the video of the previous similar hit recorded on 8 January, the target, while clearly hit, did not appear to be downed. Saudi forces confirmed the hit, while saying the jet safely landed at a Saudi base. [27] [28] Saudi official sources confirmed the incident reporting that it happened at 3:48 pm local time after a surface-to-air defense missile was launched at the fighter jet from inside Saada airport.
