The Curtiss SC Seahawk, capable of being fitted with a float or wheeled landing gear, was America’s best World War II floatplane scout

The Curtiss SC Seahawk was a scout seaplane launched from a Navy cruiser for observation. According to the plane’s page in Wikipedia, the single-seat seaplane landed in water and was retrieved by hoist. Though capable in concept, the Curtiss SC Seahawk did not see significant action during World War II. By the end of the war, helicopters were replacing seaplanes.
The Curtiss Aeroplane and Motor Co. designed the Seahawk for the U.S. Navy during World War II. In the late stages of the war and into peacetime, the Seahawk gradually replaced the existing Curtiss SO3C Seamew and Vought OS2U Kingfisher floatplanes.

Curtiss Production Order
Work began in June 1942 following a U.S. Navy Bureau of Aeronautics request for observation seaplane proposals. Curtiss submitted the Seahawk design on Aug. 1, 1942, and a contract for two prototypes and five service test aircraft was awarded on Aug. 25. Before the prototypes’ first flight, a production order for 500 SC-1s followed in June 1943.
While only intended to seat the pilot, a bunk was added in the aft fuselage for rescue or personnel transfer. Two .50 caliber M2 Browning machine guns were fitted in the wings, and two underwing hardpoints allowed the carriage of 250-pound bombs or surface-scan radar on the right wing. The wings were foldable. The main float, designed to incorporate a bomb bay, is claimed to have been prone to leaks. Curtiss modified the design to carry an auxiliary fuel tank.

The first flight of a prototype XSC-1 took place on Feb. 16, 1944, at the Columbus, Ohio, Curtiss plant. Flight testing continued through April 28, when the last of the seven pre-production aircraft took to the air. Nine more prototypes were built under the designation SC-2 with a second seat and modified cockpit. Series production was not undertaken.

Seahawk History
The first serial-production Seahawks were delivered to the USS Guam on Oct. 22, 1944. All 577 aircraft eventually produced for the Navy were delivered on conventional landing gear. The planes were then flown to the appropriate naval air station, where floats were installed for service as needed.
Capable of being fitted with a float or wheeled landing gear, the Seahawk was America’s best World War II floatplane scout. However, its protracted development time meant it entered service too late to see significant action in the war. It was not until June 1945, during the pre-invasion bombardment of Borneo, that the Seahawk was involved in military action. By the war’s end, seaplanes were becoming less desirable, with helicopters replacing the Seahawk soon afterward.
The Seahawk’s tri-color camouflage and markings were required by U.S. Navy regulations from 1944 to 1945 and later postwar regulations.
There are no known surviving examples of the Seahawk today.

He started with Curtiss-Wright Corp., a pioneer in making flying machines. He went on to work at North American Aviation and Rockwell International.
