Fokker-Atlantic XLB-2

Last revised July 7, 1999

The Atlantic Aircraft Corporation of Teterboro, New Jersey was the American subsidiary of the Holland-based Fokker aircraft manufacturing company. It manufactured some Fokker-designed commercial airliners in the United States. Among these were Fokker's series of pioneering high-winged monoplane airliners.

Atlantic submitted a monoplane design in response to a 1927 Army competition for a successor to the Martin-designed NBS-1 bomber. A single prototype was ordered under the designation XLB-2. The serial number was 26-210. The XLB-2 was developed from the Fokker series of monoplane transports, and had the distinction of being the first USAAC bomber designed as a monoplane. It was based primarily on the Fokker C-2 transport, which was the famous aircraft which had made the flight from Oakland, California to Wheeler Field, Hawaii on June 28-29, 1927.

The XLB-2 was powered by a pair of 410hp Pratt & Whitney R-1340 Wasp radials suspended underneath the high cantilever wing. A crew of five was carried. The bombardier position was housed inside a glazed area in the lower nose. A pair of 0.5-inch machine guns were mounted in each of two open defensive gunner positions, one situated in the extreme nose and the other in a dorsal position on the upper rear fuselage. A single gun could be fired through a position in the lower rear fuselage. A 2050 pound load of bombs could be carried.

The aircraft was later fitted with a pair of 525 hp R-1690-1 radials, which raised the maximum speed from 116 mph to 123 mph. However, the performance of the XLB-2 was not much better than that of existing Army biplane bombers. In addition, the Army was quite reluctant at the time to consider such radical innovations as cantilever monoplane designs, and the XLB-2 was not ordered into production.
