Common card · No. 367243

The ASM-N-2 Bat, originally designated as the Bomb MK 57 and later as the SWOD Mk 9, was a United States Navy World War II radar-guided glide bomb which was used in combat beginning in April 1945. The Bat was developed and manufactured by a unit within the National Bureau of Standards (later a part of the Army Research Laboratory), with assistance from the U.S. Navy's Bureau of Ordnance, the Massachusetts Institute of Technology, and Bell Telephone Laboratories. It is considered to be the first fully automated guided missile used in combat.
