The Curtiss O-52 Owl is an observation aircraft used by the United States Army Air Corps before and during World War II.

Curtis designated it the Curtiss Model 85, and it was powered by a Pratt & Whitney Wasp radial engine.

As a result, the O-52 was relegated to courier duties within the U.S. and short-range submarine patrol over the Gulf of Mexico and Atlantic and Pacific Oceans O-52 were used by the 2nd Reconnaissance Squadron, which flew them out of Puerto Rico and Trinidad, to search for Nazi U Boats.

They were used operationally for artillery fire spotting and general photographic and observation platforms in north and central areas on the Russian Front during spring–summer 1943.
