Curtiss SOC-4 “Seagull” (1938)

The SOC was the last of the "Curtiss biplanes in operational service" with the U.S. Navy and was designed for use as a scout aircraft for battleships and cruisers--capable of catapult operation and landing at sea. The Coast Guard acquired the final three produced by Curtiss in 1938 and these were designated as SOC-4s. They were assigned the Coast Guard call numbers V171, V172, and V173.
