Viper Strike

The GBU-44/B Viper Strike glide bomb is a GPS-aided laser-guided variant of the Northrop Grumman Brilliant Anti-Tank (BAT) munition which originally had a combination acoustic and infrared homing seeker. The system was initially intended for use from UAVs, and it has also been integrated with the Lockheed AC-130 gunship, giving that aircraft a precision stand-off capability. The Viper Strike is now produced by MBDA.

The Viper Strike bomb first underwent testing in 2003. On March 29 and 30, Viper Strikes released from an RQ-5 Hunter UAV scored 7 out of 10 direct hits at White Sands Missile Range. The other three bombs missed their targets by a few feet but still inflicted measurable damage. The objective of the tests was to validate the concept of the Viper Strike and the operational feasibility of Viper Strike integrated on the Hunter UAV. In June 2005, Northrop integrated the Global Positioning System (GPS) into the laser-guided munition to provide highly accurate midcourse guidance. This allowed the weapon to be launched from much greater altitude and standoff range. During tests, an unarmed weapon successfully acquired GPS data after dispensing from an aircraft and flew to pre-assigned GPS waypoints. Following an extended, nearly horizontal midcourse flight, the GPS-enhanced munition switched over to the semi-active laser seeker once it entered the target area to detect and track the laser-designated target. In January 2007, Viper Strikes successfully destroyed a series of moving and stationary targets in testing at the White Sands Missile Range. They were guided to their targets by the Hunter UAV's laser targeting system.

The GBU-44/B Viper Strike was first used in combat in September 2007. An MQ-5A Hunter UAV used one to kill two men who were setting up a roadside bomb.
