In 1943 Vought aircraft, makers of the legendary Corsair, were asked to build a test bed aircraft featuring the same engine and straight wings while utilizing a number of common structural elements. The intent was to test the Corsair’s mighty R-4360 engine mated with a turbosupercharger (coolest word ever). What do you need for a straight winged Corsair? Long landing gear to accommodate its huge prop. As this was a high altitude test bed it featured a pressurized four place cabin in place of the fighter’s single cockpit.

The R-4360 was a mainstay of the allied war effort on the Corsair and was used on such aircraft as the B-50, the Martin Mars, the B-36 and the Hughes Hurcules (Spruce Goose). The 71.5L engine made between 3000-3500HP. Turbosupercharging would give it even more power.

The V-326 was used by a Pratt and Whitney as a test bed for a couple of different engines after the initial work on the 4360, but there is little published on the web detailing its history.
