The Vympel K-13 is a Soviet infrared-homing air-to-air missile, one of the first of its kind in the Soviet Union's arsenal. During the Second Taiwan Strait Crisis, in 1958, a PLAAF fighter was hit by an American AIM-9 "Sidewinder" which did not detonate. This almost intact weapon was sent to Moscow, where the design was duplicated and mass-produced for use by both air forces, becoming the K-13. So close is the reverse-engineering that AIM-9 components are compatible with the K-13 and vice-versa. Its effective range is of 3.5km, limited by lock-on distance

This munition cannot be mounted on a vehicle without a modern Fire Control System (FCS) to guide it. Typically, the presence of such a system is hinted at in the vehicle's description. However, the most surefire way of knowing is through the Electronics Technology 🔋 tag and/or the presence of either an Airborne Radar or a Surface Radar with (Missile Guidance) in its inventory description.
Heat-Seeking
This smart munition tracks its targets through an infrared seeker which locks on to hot surfaces such as engines, flares or occasionally the Sun.
