The AGM-158 JASSM is an air-to-surface cruise missile developed by Lockheed Martin. This semi-stealthy long-range missile was created in 1995 and continues to serve the United States Air Force and some other international Air Forces. The AGM-158 has a single vertical fin and wings that are folded prior to flight. Once launched, the wings automatically unfold. The AGM-158 is guided by inertial navigation and finds targets through its imaging infrared seeker.
