variants with their own articles=The Boeing TB (or Model 63) was a torpedo bomber built for the US Navy in 1927. It was a large unstaggered, equal-span biplane of conventional configuration with interchangeable float and wheeled undercarriage. As a landplane, the main gear units carried twin wheels. The underside of the fuselage incorporated a glazed station for the bombardier. Even before the three XTB-1s were delivered, the Navy's Bureau of Aeronautics had changed its opinion about what was needed in a torpedo bomber, and based on experience with the NAF XTN-1 had decided that a twin-engine aircraft would better suit the role. Having thus been made redundant, no TBs past the three prototypes were built.
