The Air Intercept Missile (AIM)-9X Sidewinder is the latest of the Sidewinder family of short-range air-to-air missiles. It features a high off-boresight focal-plane array seeker mounted on a highly maneuverable airframe with a greatly improved infrared counter-countermeasures feature. The AIM-9X incorporates many AIM-9M legacy components (rocket motor, warhead and active optical target detector), but its performance far exceeds the legacy Sidewinder. Unlike previous AIM-9 models, the AIM-9X can even be used against targets on the ground.
The AIM-9X Block II is the most advanced short range air-air missile in the U.S. inventory, capable of using its datalink, thrust vectoring maneuverability, and advanced imaging infrared seeker to hit targets behind the launching fighter. The AIM-9X Block II completed operational test and the Navy declared initial operational capability in the spring of 2015.
