The Consolidated Model 2 was a PT-1 biplane trainer diverted to the United States Navy for a trainer competition in 1925. It beat out 14 other designs, and was ordered into production as the NY-1.[1]
The NY-1 was essentially a PT-1 with provisions for the wheeled landing gear to be replaced by a single large float under the fuselage and two stabilising floats under the tips of the lower wing. A larger vertical tail was added to counter the effect of the floats.[1] The NY-2 had a longer span wing fitted to overcome the high wing-loading issue of the seaplane version. Tested with complete success during October 1926, the Navy ordered 181 with the uprated R-790-8 Wright Whirlwind J-5 engine of 220lk=inNaNlk=in.[1] The NY-3 aircraft were similar to the NY-2 but had 240hp Wright R-760-94 engines.
The NY-1's first flight was November 1925, with deliveries starting May 1926.[1] The NY-2s first flight was October 1926. The Navy had 108 in active use in 1929, with 35 more assigned to reserve squadrons.The NY-3 was delivered in 1929. The NY series was being phased out in the mid-1930s, with 15 in service in 1937, and one in service in 1939.
