Sikorsky XBLR-3
The Sikorsky XBLR-3 was an experimental bomber design developed by Sikorsky Aircraft to compete in the United States Army Air Corps "Project D" design competition of 1935. In March 1936 the USAAC canceled the Sikorsky XBLR-3 in favor of the remaining two competitors: the Boeing XBLR-1 (Later XB-15) and the Douglas XBLR-2 (Later XB-19).
