The Douglas XB-19 was the largest bomber aircraft built for the United States Army Air Corps until 1946. It was originally given the designation XBLR-2 (XBLR- denoting Experimental Bomber, Long Range).

Design and development

The purpose of the XB-19 project was to test the flight characteristics and design techniques associated with giant bombers. Douglas Aircraft Company strongly wanted to cancel the project, because it was extremely expensive. Despite advances in technology that made the XB-19 obsolete before it was even completed, the Army Air Corps felt that the prototype would be useful for testing. Its construction took so long that competition for the contracts to make the XB-35 and XB-36 occurred two months before its first flight.

The plane finally flew on June 27, 1941, more than three years after the construction contract was awarded. In 1943, the original Wright R-3350 engines were replaced with Allison V-3420-11 V engines. After completion of testing, the XB-19 served as a cargo carrier until it was scrapped in 1949.

Survivors

The newly formed U.S. Air Force had begun plans to save the B-19 for eventual display, but in 1949 the Air Force did not yet have a program in place to save historic aircraft, and the Air Force Museum had not yet been constructed. As a result, the B-19 was scrapped, but one of its enormous main tires was saved and has been on display at the National Museum of the United States Air Force in Dayton, Ohio for many years.[1] **Error: The tire referred to here was actually the original landing gear of the XB-36.
