The Coast Guard acquired a single RT-1 on 20 February 1935 as an executive transport for use of the Commandant as well as the Secretary of the Treasury. It was damaged in an accident in 1940 and was decommissioned that December and sold to a private company. The Coast Guard initially gave the RT-1 the serial number 382, and after October 1936, changed it to V-150.
The Coast Guard purchased one of these aircraft in 1934 for electronics test flying under contract #TCG-23248 at a cost of $11,370. It was stationed at the Coast Guard Air Station, Floyd Bennett Field, Brooklyn, NY, and was given the Coast Guard serial number 149. By 1939 it was based with the Air Patrol Detachment at Air Station Cape May, NJ.
