WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Large equal-span, unstaggered wings that can be folded aft, reducing the span to 21 ft 8 in for storage. Power came from a single 730 hp Packard 3A-2500 engine, and the crew of three were pilot, gunner and bombardier.

History

The TB was an improved version of the Martin T3M and first flew on 4 May 1927. It was built entirely of dural with a fabric covering.

Variants

The wheeled undercarriage could be interchanged with floats. No TBs beyond the three XTB-1 prototypes were built.

Where you'll see it

Before the three XTB-1s were delivered, the Navy decided that a twin-engine aircraft would suit the torpedo-bomber role better, so the TB went no further than the prototypes.
