The Great Lakes XTBG-1, also known as "Avenger"[citation needed] (a name coincidentally used for the successful Grumman TBF), 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]

Design[edit]

Featuring retractable landing gear and a fully enclosed weapons bay for its torpedo, the XTBG-1 had the odd feature of the torpedo-aimer seated forward of the wing, in a small, enclosed compartment.[3]
