The Boeing XB-15 (Boeing 294) was a United States bomber aircraft designed in 1934 as a test for the United States Army Air Corps (USAAC) to see if it would be possible to build a heavy bomber with a 5,000 mi (8,000 km) range. For a year beginning in mid-1935 it was designated the XBLR-1. When it first flew in 1937, it was the most massive and ...

XB-19A at Davis-Monthan Air Force Base before scrapping. The new U.S. Air Force had plans to save the XB-19 for eventual display, but in 1949 the Air Force did not have a program to save historic aircraft and the Air Force Museum had not yet been built. [10] [11] The XB-19 was therefore scrapped, but two of its enormous main tires were saved. [c]
The Boeing XB-39 Superfortress was a United States prototype bomber aircraft, a single example of the B-29 Superfortress converted to fly with alternative powerplants. It was intended to demonstrate that the B-29 could still be put into service even if the first choice of engine, the air-cooled Wright R-3350 radial engine, ran into development or production difficulties.
The XB-38 was the result of a modification project undertaken by Vega (a subsidiary of Lockheed) on a Boeing B-17 Flying Fortress to fit it with liquid-cooled Allison V-1710-89 V-12 engines. It was to be an improved B-17, and an alternative if the normally fitted air-cooled Wright R-1820 radial engines became scarce. Completing the ...
The Boeing XB-55 (company designation Model 474) was a proposed Boeing aircraft designed to be a strategic bomber. The XB-55 was intended to be a replacement for the Boeing B-47 Stratojet in United States Air Force (USAF) service.
The Douglas XB-42 Mixmaster is an experimental American bomber aircraft, designed for a high top speed. The unconventional approach was to mount the two engines within the fuselage driving a pair of contra-rotating propellers mounted at the tail in a pusher configuration , leaving the wing and fuselage clean and free of drag-inducing protrusions.
The Lockheed XB-30 (company model L-249) [1] was the design submitted by Lockheed after the request by the United States Army Air Forces for a very heavy bomber, the same request that led to the Boeing B-29 Superfortress, the Douglas XB-31 and Consolidated B-32 Dominator.
