The Curtiss XF13C (Model 70) was a carrier-based fighter aircraft.
The XF13C was a naval fighter featuring an all-metal construction, with a semi-monocoque fuselage, manually retractable landing gear and an enclosed cockpit.
The aircraft was designed to facilitate conversions from biplane to monoplane and vice versa.
The United States Navy bought a prototype, designated XF13C-1 when in monoplane configuration, and XF13C-2 when a biplane.
The XF13C first flew in 1934 with good results realized in tests.
In 1935, the aircraft received a more powerful engine and modifications to the overly tall tailplanes.
The designation was changed to XF13C-3 for more flight testing.
No production orders were received for the Curtis XF13C, but the aircraft continued to fly for NACA in experimental work, and by VWJ-1 Squadron at Quantico.
