Originally developed as a cluster submunition for a cancelled antitank version of the MGM-140 ATACMS tactical ballistic missile, the Brilliant Anti-Tank (BAT), also called the GBU-44/B Viper Strike, weapon is an guided glide bomb that is being adapted to unmanned aerial vehicles. The original version used an acoustic sensor to find the general area of its target, with infrared terminal guidance for the final approach. The derivative fielded in 2003 uses semi-active laser homing directed by a laser designator.
