The Curtiss B-2 "Condor" was a production version of the XB-2 with more powerful engines and an improved wing design. The B-2 was initially rejected by the Army in favor of the Keystone LB-6, in part because the Curtiss aircraft was too expensive and too big to fit into existing hangars. The superior performance of the B-2, however, changed the thinking of the Air Corps leadership and a small production run of twelve B-2s was ordered in 1928-1929.
A transport version of the B-2 was tested by the Army as the C-30 and sold as the Model 18 commercial transport. The B-2 was the last bomber built by Curtiss Aircraft which concentrated on pursuit aircraft throughout the 1930s and 1940s (the Hawk series).
