The AIM-120A is no longer in production and shares the enlarged wings and fins with the successor AIM-120B. The AIM-120C has smaller "clipped" aerosurfaces to enable increased internal carriage on the USAF F-22 Raptor from four to six AMRAAMs. AIM-120B deliveries began in 1994. The AIM-120C deliveries began in 1996.

What is the aim-260a JATM program?

The United States Department of Defense (DoD) considers the AIM-260A JATM program to be the number one air-delivered weapon priority for both the U.S. Air Force (USAF) and the Navy (USN); and its acquisition out-prioritizes other weapon system improvements and modernization efforts on any fielded aircraft.
