MAU-91 "Snakeye" Bomb Fin Assembly

The MAU-91 "Snakeye" bomb fin assembly is used with both the 750-pound M117 and 1,000-pound Mk 83 low-drag general purpose bombs to retard, or slow, their fall. This allows the bombs to be delivered at high speed from low altitude without the danger of damaging the delivery aircraft from ricocheting bombs or fragments.

Since the aircraft and the weapon are traveling at the same speed when the weapon is released, the weapon and the aircraft would arrive at the target at the same time if the bomb were not slowed down.

As the weapon is released from the aircraft, the arming wire is pulled from the fin release band, and the spring-loaded fins pop open. The fins are forced to the full-open position by the air stream, which causes the weapon to rapidly decelerate and allows the releasing aircraft sufficient time to safely clear the target area.

The Ogden Air Logistics Center at Hill AFB manages many of the air munitions and fin assemblies used by the U.S. Air Force.
