In 1922 the USN received eighteen UF-1 two-place scout-observation aircraft, A6482-6499, all re-designated to UO-1.

The two 1928 UO-1C (A7007 and one other) were a wheeled trainer version for USN Reserve. Possibly other conversions as the designation was also used for planes modified for catapult launching, regardless of floats or wheels.
