The AGM-158 Joint Air-to-Surface Standoff Missile (AGM-158 JASSM) is a low detection standoff air-launched cruise missile developed by Lockheed Martin for the United States Armed Forces.[7] It is a large, stealthy long-range weapon with a 1,000-pound (450 kg) armor piercing warhead. It completed testing and entered service with the U.S. Air Force in 2009, and has entered foreign service in Australia, Finland, and Poland as of 2014. An extended range version of the missile, the AGM-158B JASSM-ER (Joint Air-to-Surface Standoff Missile-Extended Range), entered service in 2014 as well as an anti-ship derivative, the AGM-158C LRASM (Long Range Anti-Ship Missile) in 2018. By September 2016, Lockheed Martin had delivered 2,000 total JASSMs comprising both variants to the USAF.[8] In August 2024 the US was reportedly considering supplying JASSM missiles to Ukraine.[9][10]
