The AUM-N-2 Petrel, also known as Kingfisher C and AUM-2, was an air-to-surface missile produced as part of Project Kingfisher for the United States Navy. Intended to use against enemy surface ships and surfaced submarines giving aircraft the ability to deliver aerial torpedoes from outside the range of defensive armament, it saw brief operational service in the late 1950s. The project was never considered a high priority by the Navy however, as it was useless against submerged submarines, which were considered the greatest potential threat.
Following its withdrawal from operational usage, the Petrel was used as a target drone, receiving the designation AQM-41A shortly before being retired from service altogether.
