The GBU-44/B Viper Strike (Viper-E) is a 44lb., air-launched guided munition for stand-off precision attack. Currently in production, Viper-E is a low-risk, mature program that provides a turn-key precision weapon solution for fixed wing, helicopter, and UAV platforms. Being used with US Army, US Special Operations, and US Marine Corps aircraft and UAVs, the Viper-E weapon glides to the target using GPS-aided navigation and a semi-active laser seeker to attack targets with combat-proven pinpoint accuracy. Viper Strike is optimized for attack profiles that require either a steep or shallow final attack angle. This flexibility allows low-collateral damage effects in both mountainous terrain or urban canyons where strict rules of engagement are in force. Its relatively small warhead size combined with laser accuracy ensures target destruction with low collateral damage in cluttered urban environments.

Viper Strike’s GPS Inertial Navigation System (INS) combined with Semi-Active laser (SAL) guidance provides positive control until impact.  GPS/INS navigation provides accurate mid-course guidance to the target area allowing for final SAL guidance.

Viper Strike’s dual mode guidance and agility provide a high degree of operational flexibility. The weapon can be released in poor weather yet retain laser precision from man-in-the-loop targeting by laser designation as the Viper-E approaches the target. Viper-E is compatible with any NATO standard laser designator, either from the air, from the sea or from ground forces.
