Curtiss F6C-4 Hawk as Training Aircraft, c.1930
Here we see a Curtiss F6C-4 'Hawk', probably being used as a fighter training aircraft, c.1930. The F6C-4 introduced a Pratt & Whitney Wasp radial air-cooled engine, replacing the inline engine used on earlier versions of the F6C. Radial engines were widely adopted by the US Navy as they were easier to maintain at sea than inline engines.
