Lockheed redesignated the aircraft delivered to the USAAF as Model 137-27-02. The 101 USAAF B-34As were:
57 B-34A-2-VE bomber trainers
28 B-34A-3-VE gunnery trainers
16 B-34A-4-VE target tugs.
All Lockheed Ventura variants were manufactured at the wholly-owned subsidary, Vega Aircraft Corp., hence these aircraft are also known as Lockheed-Vega aircraft.
This photograph shows a B-34A-3-VE over Tyndall Field, Panama City, Florida, being "attacked" by an "enemy" fighter pilot in a North American AT-6 Texan. The gunnery student in the B-34 top turret must "shoot down" the "fighter" aircraft with a camera gun mounted in the turret. When the cross-hair on the film intersect on the plane, a hit is scored."
