OS2U Kingfisher

From open-encyclopedia.com - the free encyclopedia.

The Vought OS2U Kingfisher was a catapult-launched, observation floatplane. The OS2U was a neat, compact mid-wing monoplane, with a big central float and small stabilising floats. Performance was modest, because of its light engine. The OS2U could also operate on fixed, wheeled landing gear. For the US Navy, the OS2U was with 1519 built the most used shipboard observation aircraft, and the most popular one of World War II --- although that doesn't mean that much, the competition including failed aircraft such as the SO3C and SC. The OS2U not only served on the battleships and cruisers of the USN, but also with the Royal Navy and the USCG.
