General Dynamics Ordnance and Tactical Systems and the U.S. Army have demonstrated a precision-guided mortar for use on small UAVs. The test, conducted under the Army’s Air Drop Mortar program, was intended to show a rapid target response capability sought by the Army, Marine Corps and special forces.

General Dynamics announced that it has launched three mortars in separate engagements from a TigerShark UAV at altitudes of about 7,000 feet. The munition used was an 81-mm mortar equipped with General Dynamics’ roll controlled fixed canard (RCFC) system and a fuzing system developed by the Army Armament Research and Development Engineering Center (Ardec) at Picatinny Arsenal, N.J.

The RCFC guidance kit includes a GPS-based guidance and navigation system that adds precision strike capability to existing mortars. The system is nose-mounted on a US M821 mortar bomb. The system has been demonstrated on multiple mortar calibers in both air-drop and tube-launch applications, according to General Dynamics.

The pusher-prop TigerShark, supplied by Navmar Applied Sciences, of Warminster, Pa., weighs 260 pounds, with a payload capacity of 50 pounds and endurance of about 10 hours. Introduced in 2005, the UAV was manufactured for a time by L-3 Unmanned Systems. The U.S. Navy is also developing the TigerShark for intelligence, surveillance and reconnaissance missions.

“This effort demonstrated a low-cost, tactical version of a GPS strike weapon for UAV platforms,” said Mark Schneider, general manager of Ordance and Tactical Systems’ Seattle operations. “Together with Ardec, we have demonstrated a weapon in the 10-pound class for tactical UAVs that can be used to engage and defeat targets quickly.”
