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

A large flying-boat hull with wingtip floats and two radial engines set well out on a high straight wing set it apart from smaller Catalina-type flying boats.

Specifications

Figures are for the representative variant described above; marks differ. See how AircraftIQ sources figures.

History

Designed for very long over-water patrol endurance, only one prototype was completed; wartime priorities shifted Boeing's factory capacity to B-29 bomber production, so the promising design was cancelled after just the single aircraft.

Variants

No production variants followed; the sole XPBB-1 remained a one-off testbed.

Where you'll see it

The single prototype was used for evaluation and utility flying by the US Navy before being scrapped after the war; it had no UK service.
