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 Sikorsky XBLR-3 was powered four 1600 hp 24 cylinder Allison V-3420 engine driving one 4.57m diameter metal adjustable propeller each.

[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.
