An unmanned range-programmable airburst weapon system provides automated tracking and prosecution of soft targets such as UAVs at close ranges. A range-programmable gun that fires airburst rounds and a seeker that images the target within a FOV are mounted on a gimbaled turret. A tracking controller is responsive to a target cue to point the seeker to acquire the target and to subsequent tracking commands from the seeker to maintain the target in the seeker's FOV. A fire controller is responsive to tracking commands and range-to-target measurements to compute a ballistic firing solution to range program an airburst round and to point and fire the gun so that the round explodes in mid-air at a predicted target position.

An agile, high-power, reliable DIRCM system that is easily extended to address sophisticated UV or UV-visible capable multi-band threats includes a missile warner having missile warning receivers (MWRs), one or two-color suitably in the mid-IR range, that detect likely missile launch and pass the threat coordinates to a pointer-tracker having a Roll/Nod gimbal on which the IR laser transmitter is mounted. The pointer-tracker slews the gimbal to initiate tracking based on the threat coordinates and then uses its detector to continue to track and verify the threat.
