GBU-44/B Viper Strike (Weapon)

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.
