The Vought OSU Kingfisher, The Seaplane That Sank A U-Boat

Vought OSU Kingfisher

The Vought OS2U Kingfisher was an American catapult-launched observation floatplane. It was a compact mid-wing monoplane, with a big central float and small stabilizing floats. Performance was modest, because of its light engine. The OS2U could also operate on fixed, wheeled, taildragger landing gear.

The OS2U was the main shipboard observation aircraft used by the United States Navy during World War II, and 1,519 of the aircraft were built. It served on battleships and cruisers of the US Navy, and with the United States Coast Guard, the United States Marine Corps in VMS-3, the Royal Navy and the Soviet Navy. The Royal Australian Air Force also operated a few Kingfishers from shore bases.

The Naval Aircraft Factory OS2N was the designation of the OS2U-3 aircraft built by the Naval Aircraft Factory in Philadelphia, Pennsylvania. The OS2U first flew on March 1, 1938.”

A Kingfisher sank a German U-boat 576 in July 1942 using a gravity bomb.
