Lockheed Martin has been funded by the US Air Force (USAF) to take the next steps in the development of an ultra long-range version of the AGM-158 Joint Air-to-Surface Stand-off Missile (JASSM) air-launched precision strike missile.

Known as the JASSM-Extreme Range (JASSM-XR), the new variant will evolve the existing AGM-158B JASSM-ER weapon to extended range beyond 1,000 km. A new wing design already under way will feature as part of JASSM-XR.
