The Huff-Daland XHB-1 "Cyclops" was a 1920s American prototype heavy bomber designed and built by the Huff-Daland company.[1]
The XHB-1 was designed as an enlarged version of the earlier LB-1 powered by a single 750 hp Packard 2A-2540 nose-mounted engine. It had a crew of four and had a 4000 lb bomb load. The Army decided not to order the Cyclops into production as it had decided single-engined aircraft were not suitable for the role.
A twin-engined version was developed as the XB-1 Super Cyclops.[2]
