Here the 1st prototype is flying again after being grounded for installation of an upgraded P&W R-2800-34W engine plus other modifications. In this view the exhaust pump engine cooling outlet is clearly seen. The USN were delighted with its diving characteristics, but stall and spin recovery was a problem. The delay caused by design changes resulted in other models taking over its role, consequently the contract was terminated on 3 September 1946. Five completed aircraft went to meet their fate at NAES Phillidelphia and were eventually "stricken from inventory". Dates where known: prototypes 44313 (unknown); 44314 (March 1948). Production aircraft: 90484 & 90485 (unknown); 90486 (April 1948).

The Fleetwings (officially Kaiser-Fleetwings by now) Model 44 was a dive bomber designed for the US Navy to replace the Curtiss Helldiver. Here the prototype is returning from an early (possibly first) test flight which took place on 12 April 1945 piloted by William H. Engle. It is landing on one of the new paved runways at Fleetwings Field which the USN had built in support of the BTK-1 project. The engine was a P&W R-2800-22W giving 2400 hp and a novel design feature was an exhaust pump engine cooling system. This proved unsatisfactory and was eventually replaced with conventional cowl flaps. Collection holder William Engle is the son of Fleetwings test pilot William H. Engle.

Acquired by American Airlines from the Reconstruction Finance Corporation on 7 December 1945 and modified as a flying test bed for airborne radar research. The print has a Kaiser-Fleetwings rubber stamp dated 'SEP 20 1946' on the back. That plus the inclusion of the company's Chief Engineer (R.W. Ayer) in the photo suggests their involvement in providing the strange-looking cupola. On 8 August 1947 the aircraft was wrecked when it stalled into the East River during a single engine missed approach at LaGuardia/NY.
