On 19 April 2010 the Army issued a "solicitation for sources sought" from defense contractors for a munition for the Shadow system with a deadline for proposals due no later than 10 May 2010. Although no specific munition has been chosen yet, some possible munitions include the Raytheon Pyros bomb, the General Dynamics 81 mm 4.5 kg (10-pound) air-dropped guided mortar, as well as the QuickMEDS system for delivering medical supplies to remote and stranded troops. The Army subsequently slowed work, and the Marine Corps then took the lead on arming the RQ-7 Shadow. Raytheon has conducted successful flight tests with the Small Tactical Munition, and Lockheed Martin has tested the Shadow Hawk glide weapon from an RQ-7. On 1 November 2012, General Dynamics successfully demonstrated their guided 81 mm Air Dropped Mortar, with three launches at 7,000 ft hitting within seven meters of the target grid.
