20th Century Fox Aichi D3A Val
It was necessary to create a Japanese Air Force to accurately film 20th Century Fox's "Tora! Tora! Tora!” since no World War II Japanese aircraft existed in any quantity. Three types were needed; Nakajima B5N-2 "Kate" torpedo bombers, Mitsubishi A6M "Zero" fighters, and Aichi D3A "Val” dive bombers. Ten of each were needed.
The "Vals" were made from BT-13's, the Vultee "Vibrator", also with the 600 hp Pratt & Whitney. Primary modifications to the BT-13 were a new cowl, extended canopy "Green-house", re-designed vertical fin, wing dive brakes, heavily spatted main gear, and bomb rack. With the larger engine and wheel fairings this aircraft performs better than the original.
