The Boeing TB (Model 63) was an American torpedo-bomber biplane designed by the US Navy and built by Boeing in 1927.
Recognition (WEFT)
| W — Wings | Mid-mounted, straight |
|---|---|
| E — Engines | 1 × piston, nose-mounted |
| F — Fuselage | Glazed bombardier station in the underside of the fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Equal-span unstaggered biplane wings that fold aft
- Glazed bombardier station in the underside of the fuselage
- Twin wheels on each main undercarriage unit
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.
Specifications
- The Boeing TB has a length of 12.45 m (41 ft).
- It has a wingspan of 16.76 m (55 ft).
- Its maximum speed is 185 km/h (115 mph).
- Typical crew: 3.

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.
