Sikorsky XBLR-3

The Sikorsky XBLR-3 was a four-engine bomber, designed in 1935 and 1936.

The original XBLR-3 was a twin boom design with both pusher and tractor propellers and bristling with gun stations which made it look like the aircraft illustrated in popular comics and pulp fiction of the time.

Sikorsky Aircraft was apparently not all that committed to building the machine. Experimental military aircraft of the period had to be developed at the contractors expense. Cost-plus contracts were a product of the rearmament programs of the 1940s.
