https://en.wikipedia.org/wiki/Huff-Daland_XB-1
The Huff-Daland XB-1 was a prototype bomber aircraft built for the United States
Army Air Corps.
The XB-1 was the first aircraft named using just a B- designation. Prior to
1926, the U.S. Army used LB- and HB- prefixes, signifying 'Light Bomber' and
'Heavy Bomber'. The first XB-1, called the Super-Cyclops by Huff-Daland, was an
extension of the earlier Huff-Daland XHB-1 'Cyclops'. It was essentially the
same in size, but sported a twin tail and twin engines.
The XB-1's gunnery arrangement was new for an American bomber, but it had been
previously used by the British and the Germans near the end of World War I. The
Army Air Corps had decided that single-engined bombers such as the XHB-1
performed more poorly and with less safety than the more traditional
twin-engined bomber.

The aircraft flew for the first time in September 1927. Its original Packard
engines did not provide enough power for the aircraft, and it was refitted with
more powerful Curtiss Aircraft "Conqueror" engines. This new configuration was
designated the XB-1B.
Three other similar aircraft designs were requested by the Army Air Corps around
the same time which competed against the XB-1 for the contract. Of these three
(the XB-2 Condor, the Sikorsky S-37 and the Fokker XLB-2), the Curtiss model
eventually won, and only a single XB-1 was ever produced.
