Curtiss SC Seahawk

Work began in June 1942, following a US Navy Bureau of Aeronautics request for observation seaplane proposals. Curtiss submitted the Seahawk design on 1 August 1942, with a contract for two prototypes and five service test aircraft awarded on 25 August. While only intended to seat the pilot, a bunk was provided in the aft fuselage for rescue or personnel transfer. Two 0.5 in (12.7 mm) M2 Browning machine guns were fitted in the wings, and two underwing hardpoints allowed carriage of 250 lb (113 kg) bombs or, on the right wing, surface-scan radar. The main float, designed to incorporate a bomb bay, suffered substantial leaks when used in that fashion, and was modified to carry an auxiliary fuel tank. Flight testing continued through 28 April, when the last of the seven pre-production aircraft took to the air. Nine further prototypes were later built, with a second seat and modified cockpit, under the designation SC-2; series production was not undertaken. ==Operational history==

The first serial production Seahawks were delivered on 22 October 1944, to . All 577 aircraft eventually produced for the Navy were delivered on conventional landing gear and flown to the appropriate Naval Air Station, where floats were fitted for service as needed. Capable of being fitted with either float or wheeled landing gear, the Seahawk was arguably America's best floatplane scout of World War II. 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 end of the war, seaplanes were becoming less desirable, with the Seahawk being replaced soon afterward by helicopters. Tri-color camouflage and markings on the Seahawk were in accordance with US Navy regulations from 1944, 1945, and later postwar regulations. ==Variants==
