The Mark 25 torpedo was an aircraft-launched anti-surface ship torpedo designed by the Division of War Research of Columbia University in 1943 as a replacement for the Mark 13 torpedo.[1] It was designed for higher speed, greater strength and more ease of manufacture compared to the Mark 13. Naval Ordnance Station Forest Park built twenty-five units in 1946 for test and evaluation, however, this torpedo was never mass-produced due to the large inventory of Mark 13s left over at the end of World War II. Moreover, the role of Naval aircraft changed from a torpedo strike platform to an antisubmarine warfare platform.
