The Low Cost Autonomous Attack System (LOCAAS). In 1998 the U.S. Air Force and U.S. Army Lockheed Martin began to examine the feasibility of a small, affordable cruise missile weapon for use against armoured and unarmoured vehicles, materiel and personnel, and if so develop a demonstration program.[1] The program has cost approx. $150,000,000 so far; the cost per unit is calculated to be $30,000 based on a production of 12,000 units.

After being launched from a weapon platform, it is guided by GPS/INS to the target general area, where it can loiter. A laser radar (LIDAR or LADAR) illuminates the targets, determines their range, and matches their 3-D geometry with pre-loaded signatures. The LOCAAS system then selects the highest priority target and selects the warhead's mode for the best effect.[2]

It is part of the Small Bomb System (SBS) program. The LOCAAS has been cancelled.
