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.^[1]^[2] 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). The XBLR-3 was one of the last fixed wing aircraft designed by the Sikorsky company.

Design and development

The Sikorsky XBLR-3 was powered four 1600 hp 24 cylinder Allison V-3420 engine driving one 4.57m diameter metal adjustable propeller each. The Allison V-3420 engine was specified for all three entries in the 1935 "Project D" competition.^[1]^[2]

Details of the Sikorsky XBLR-3's armament are not known, however a rotating dorsally-mounted Ball turret was included in the preliminary wooden model, and bombs of unknown parameters can be assumed to be included in the design perimeters.^[1]
