Lockheed Martin has unveiled the AGM-158 JASSM-XR, the latest extended-range version of its Joint Air-to-Surface Standoff Missile (JASSM). As a variant of a proven and air-qualified family of weapons, the XR variant offers a low-risk solution compared to a ‘clean sheet’ new weapon. It is designed to offer significantly increased range and payload capacity compared to previous models, enabling strikes from further distances while carrying larger warheads. According to Lockheed Martin, by leveraging the mature JASSM and LRASM production line, established supply chain, mission planning, and software infrastructure, and implementing a few structural changes, XR can significantly reduce development and production time.
With its 1,000 lb warhead, JASSM-XR can deliver precision strikes on heavily defended targets, with a range exceeding 1,500 miles (2,400 km). This advanced capability allows the missile to penetrate deep into enemy territory while staying out of reach of modern air defense systems. Its low-observable design ensures high survivability against detection and interception.
This new variant will be integrated with various platforms, including the B-1B Lancer, F-35, and other U.S. aircraft, strengthening long-range precision strike capabilities in future combat scenarios. The introduction of JASSM-XR reflects ongoing efforts to extend the reach of air-launched weapons while minimizing risk to crews and platforms. Lockheed Martin has leveraged its Model-Based Enterprise (MBE). This integrated digital environment spans the entire life cycle of a program, including informing upgradeable product improvements and spiral evolution to existing programs.
