Design

With the failure of the Seamew the United States Navy issued a new specification for a scouting floatplane in June 1942. On March 31, 1943, an order for two prototypes was placed with Curtiss.

Fuselage

In the rear of the fuselage a stretcher could be carried.

Prototype

The XSC-1 prototype first flew on February 16, 1944.

Production

A contract was issued in March 1943. In June 1943 500 SC-1s were ordered.

The Seahawks were produced at Curtiss' Columbus, Ohio factory as land planes with fixed undercarriages. The floats were installed by the United States Navy for the ones that they wanted to be floatplanes.

Production was cancelled when Japan surrendered.
