AIM-260 JATM

The AIM-260 Joint Advanced Tactical Missile (JATM) is an American beyond-visual-range air-to-air missile (BVRAAM) being developed and produced by Lockheed Martin. Designed to address advanced threats, the missile is expected to replace or supplement the AIM-120 AMRAAM currently in US service. 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 United States Air Force (USAF) and the Navy (USN); and its acquisition out-prioritizes other weapon system improvements and modernization efforts on any fielded aircraft.
This program differs from the Long-Range Engagement Weapon being developed by Raytheon and the Navy's possibly related AIM-424 Malice, currently in flight-testing. The JATM is also separate from the AIM-174B Gunslinger, also developed by Raytheon for the USN. Australia is to also be the first foreign country to procure the missile, with deliveries expected in 2033.
