The AGM-158 JASSM (Joint Air-to-Surface Standoff Missile) is a low observable standoff air-launched cruise missile developed by Lockheed Martin for the United States Armed Forces. It is a large, stealthy long-range weapon with a 450-kilogram (1,000 lb) 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. By September 2016, Lockheed Martin had delivered 2,000 total JASSMs comprising both variants to the USAF.
