A-26D

The Douglas A-26D Invader was intended to be an improved version of the solid-nosed A-26B with more powerful engines. Two different XA-26D prototypes were produced. The first was made by converting an B model (44-34100), by fitting a standard A-26B with two Chevrolet built 2,100hp R-2800-83 engines. This increased the aircraft's top speed by 80mph, and Douglas received an order for 750 A-26Ds, but the order was cancelled after the end of the war in the Pacific and before any aircraft had been completed. The second one was built by modifying another Invader (44-34776) and featured a 4-blade propeller design.
