The Huff-Daland LB-1 was an improved version of the XLB-1. The LB-1 had a crew of four, one more than the XLB-1, and an improved Packard 2A-2540 engine. The LB-1 was named "Pegasus" by Huff-Daland but the name wasn't used by the Army Air Corps. Ten aircraft were ordered for service testing in 1925 and first flown in July 1927.

The LB-1 had about the same performance as the XLB-1, but carried a much larger bomb load of 2,750 pounds although the range was reduced by half. The LB-1 was the basis for the larger XHB-1 (Heavy Bomber), but the single-engine bomber was never seriously considered for production beyond the test phase. These aircraft were the last single-engine bombers ever tested by the Army (or the USAF).
