Vought V-326

Vought began work on the V-326 in 1941 at the request of Pratt & Whitney. Designed as a as a test bed for the R-4360 Wasp Major radial engine, the aircraft was based on the XTBU-1 Sea Wolf and used components from the F4U Corsair. The V-326 was a low-wing monoplane with a pressurized two-seat cockpit. Its main landing gear rotated 90 degrees and retracted rearward into the wings. In the rear fuselage was a compartment for ballast. The engine's carburetor was fed by a scoop situated ahead of the vertical stabilizer.[1][2][3]

The V-326 made is first flight on June 18, 1943 at the hands of P&W chief test pilot A. Lewis McClain. Harold B. Archer flew most subsequent flights, with pressurization troubles keeping most flights below 40,000 feet (12,000 m).[1]

The second aircraft, the V-326A, made its first and only flight on August 30, 1944. It subsequently underwent modifications, though they were not completed as the need for the aircraft faded. Both aircraft were scrapped in 1946, the V-326 having only 111 hours logged.[1]
