|Though an American product, the Vought OS2U Kingfisher series served in quantity with the ranks of the British Fleet Air Arm.|
The Kingfisher series was powered by a single engine mounted at the fuselage front. The crew of two sat in separate cockpit areas with the pilot in front, just behind the engine and the rear gunner/observer in a mid-mounted cockpit position. The aircraft was made highly identifiable by the large centerline float pontoon running nearly the length of the fuselage and extended forward of the propeller. Two additional yet smaller stabilizing floats were mounted under each wing of the low-monoplane design. Additionally, the system could be adapted to land on shore bases thanks to the interchangeable landing gear / float system.
Armament consisted of light self-defensive measures and was made up of a single forward firing fixed 7.62mm machine gun and a rear-mounted 7.62mm machine gun. The system was capable of carrying up to 650 pounds of external stores and was known to undertake a few dive bombing sorties in its time aloft. In all, the Kingfisher system served the Fleet Air Arm (as the Kingfisher Mk I series), US Navy and the Inshore Patrol Squadrons quite faithfully during its wartime tenure. A fourth variant of the Kingfisher in the form of the OS2U-4 was proposed but never evolved.
