The BAT (Brilliant Anti-armor Technology), produced by Northrop Grumman, is an acoustic and infrared (IR) guided submunition that autonomously searches for, tracks and defeats armored and critical mobile targets. The BAT is a propulsionless, aerodynamically controlled vehicle (glider). The BAT is delivered to the target vicinity by the Army Tactical Missile System (Army TACMS), which is launched from the M270 Multiple Launch Rocket System (MLRS). An Army ATACMS test flight is shown above, just after the dispense of the thirteen Brilliant Anti-Armor Submunitions (BATS). The BAT is a brilliant, self-guided submunition used to autonomously locate, attack, and destroy moving tanks and other armored vehicles. BAT submunitions can be carried deep into enemy territory by a delivery vehicle, then dispersed over a target to selectively attack and destroy it. Pioneer supplies the main components of the Deceleration and Stabilization Subsystem including: the Gas Inflated Ram Air Stabilizer (GIRAS shown deployed here), the Primary and Secondary Parachutes Assemblies as well as their deployment and release mechanisms.
