Douglas XBLR-2 / XB-19
Originally designated XBLR-2 (eXperimental Bomber Long-Range 2), the XB-19 was essentially used as a test bed for very large bomber construction techniques and flight characteristics. The Douglas Aircraft Company had wanted to cancel the project because of the expense and extended construction time which made the aircraft obsolete before it ever flew. However, the Army Air Corps insisted the aircraft be completed for test use.
The XB-19's first flight was 27 June 1941, more than 3 years after the construction contract was awarded. In 1943, the original radial engines were replaced by Allison V-3420 in-line engines and the aircraft was redesignated XB-19A. After testing was completed, the XB-19A was used as a cargo/transport aircraft until 1949 when it was scrapped.
