Great Lakes XTBG

The Great Lakes XTBG-1 was an American prototype torpedo bomber, intended for service in the United States Navy as part of that service's plan to modernise its aerial striking force in the mid-1930s. The XTBG-1 was outperformed by the competing TBD Devastator, however, in addition to having instability problems[1] and only a single prototype of the three-seat design was constructed during 1935.[2]
