Martin XB-48 prototype taxiing, showing spaces between engines for cooling, tandem main gear, and nacelle outriggers The Martin XB-48 was an American medium jet bomber developed in the mid-1940s. It competed with the Boeing B-47 Stratojet , which proved to be a superior design, and was largely considered as a backup plan in case the B-47 ran ...

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 Martin XB-51 was an American trijet ground-attack aircraft. It was designed in 1945 and made its maiden flight in 1949. It was originally designed as a bomber for the United States Army Air Forces under specification V-8237-1 and was designated XA-45. The "A" ground-attack classification was eliminated the next year, and the XB-51 ...
The XB-16 was designed to meet the United States Army Air Corps (USAAC) request for a bomber that could carry 2,500 lb (1,100 kg) of bombs 5,000 mi (8,000 km; 4,300 nmi). The XB-16 (Model 145A) was to use four Allison V-1710 liquid-cooled reciprocating V-engines ; contemporary American aircraft used air-cooled radial engines .
XB-26H—This test aircraft for tandem landing gear was nicknamed the "Middle River Stump Jumper" from its "bicycle" gear configuration, to see if it could be used on the Martin XB-48. [49] (One converted) JM-1P—A small number of JM-1s were converted into photo-reconnaissance aircraft for the US Navy. [44] Marauder I
The new aircraft was the Martin 4-0-4. It had structural changes to the wings, pressurization and was lengthened slightly to take 40 passengers. Like the earlier 2-0-2, the 4-0-4 was a cantilever monoplane with a standard tail unit (cantilever tailplane and single vertical stabilizer).
The USAF eventually gave up fighting for its production and the B-70 program was cancelled in 1961. Development was then turned over to a research program to study the effects of long-duration high-speed flight. As a result, two prototype aircraft, designated XB-70A, were built; these aircraft were used for supersonic test-flights from 1964 to ...
