AVR 661
AVR 661 is an R-1 type United States Air Force "crash boat", a boat used in air-sea rescues. It is 85 feet long and has two Packard Marine 4M-2500 engines of 1500 horse power. It has a top speed of 35 knots. The boat was armed with a twin .50 caliber machine gun, a 20 mm anti-aircraft gun and two depth charges.
These types of boats were used to rescue aircraft crews at sea. The designation AVR was used for "Aircraft Rescue Vessel", so it was one of the small, fast craft, that were used for rescuing pilots from downed planes.
AVR 661 was built in 1943 for the Army Air Corps and served in the Gulf of Mexico during World War II.
After the war the Air Force sold many of its crash boats to private parties for use as yachts or commercial vessels. Many others were used as targets and sunk. AVR 661 was kept in active service assigned to Tyndall Air Force Base, near Panama City, Florida. During the Vietnam War, AVR 661 towed targets for helicopter gunship training and anti-mine training as well as to recover drones.
