The genesis of the B-36 can be traced to early 1941, prior to the entry of the US into World War II. At the time it appeared that there was a very real chance that Britain could fall, making a strategic bombing effort by the US against Germany impossible.
The United States Army Air Corps opened up a design competition for the very long-range bomber on 11 April 1941, asking for a 450 mph top speed, a 275 mph cruising speed, a service ceiling of 45,000 feet, and a maximum range of 12,000 miles at 25,000 feet.These proved too demanding for any short-term design, so on August 19, 1941 they were reduced to a maximum range of 10,000 miles, an effective combat radius of 4,000 miles with a 10,000 pound bombload, a cruising speed between 240 and 300 mph, and a service ceiling of 40,000 feet.
