The Northrop XB-35 was experimental heavy bomber aircraft developed by the Northrop Corporation for the United States Army Air Forces during and shortly after World War II. The airplane used the radical and potentially very efficient flying wing design, in which the tail section and fuselage are eliminated and all payload is carried in a thick wing. Only prototypes and pre-production aircraft were built, although interest remained strong enough to warrant further development of the design as a jet bomber, under the designation YB-49.

The B-35 was the brainchild of Jack Northrop, who made the flying wing the focus of his work during the 1930s. In theory, the B-35 could carry a greater payload faster, farther, and cheaper than a conventional bomber. The B-35 was designed to that could carry 4,500 kg (10,000 lb) of bombs to a round-trip mission of 16,000 km (10,000 mi) with a requested performance of a maximum speed of 720 km/h (450 mph), cruise speed of 443 km/h (275 mph), and service ceiling of 14,000 m (45,000 ft). This aircraft would be able to bomb Nazi-occupied Europe in the event that Britain fell (this was similar to Nazi Germany's own Amerikabomber program design competition through the RLM, itself initiated in the spring of 1942).

controls are more or less the rf standard for a plane retracts and flaps. Bombs drop and bomb bay doors open from the three position switch (upper left). the sliders aim the turrets.
