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.

[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.

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.

[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.

[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.
