History
Headquartered in
In 1926, Huff left the company, and it was soon purchased by
In 1932 the Army Air Corps issued a Circular design proposal for an advanced new heavy bomber which Ford, Martin, Boeing, Fokker, Douglas and Keystone submitted designs. The Keystone entry was for an all metal low winged monoplane bomber with retractable landing gear. The bomber would be powered by two Curtiss V-1570 geared Conqueror engines. With a crew of 5 it was armed with up to 3 x .30 caliber machine guns and could carry 2,000 lbs (907 kg) of bombs on external racks. A mock-up of the aircraft was inspected by the Air Corps in April and was withdrawn by Keystone after it was determined it could not meet the requirements. The contract was ultimately won by Martin for their Model 139, known as the B-10 Bomber. This was to be the last design submitted to the military by Keystone.[3]
Keystone itself became a manufacturing division of Curtiss-Wright and ceased production in 1932.[4] The former Keystone plant was purchased by Fleetwings in 1934.[5]
Lieut. Comdr. Noel Davis and Lieut. Stanton H. Wooster were killed in their
