Lockheed B-34-VE Lexington (Ventura IIA)


Model: Lockheed B-34-VE Lexington
Technical Description: Medium patrol bomber

Visual Aspects




Short History: On 13 August, 1941, Lockheed was awarded a Defense Agency contract for 200 medium bomber aircraft based off of the Model 18 Lodestar powered by 2,000 hp Pratt & Whitney R-2800-31s. Intended for delivery to Britain under Lend-Lease as maritime strike aircraft, they were assigned the USAAF serials 41-38020/ 41-38219 for contractual purposes. Following US entry into the war, twenty were impressed into USAAF service for coastal patrol and defence duties. Armament consisted of two fixed forward-firing 0.50-in guns in the nose, two 0. 50-in guns in a Martin dorsal turret, twin flexible 0.30-in guns in the nose and ventral positions, two flexible 0.30-in beam guns, and 3,000 lb (1,361 kg) of bombs. In service, some of the USAAF's B-34-VEs had the dorsal turret removed and AS V radar antennae installed atop the fuselage and beneath the wings.

Another bomber to the US? The ordenance is 3 tons but the B-25s can also deliver such ordenance as well and they are both at mid tier. I can't see the need for this airplane, it looks to me a faster B-25 without the armour and gunners.

what is the point of adding another bomber in a game with a horrid bomber integration ? These developers needed 3 years to apply a simple limit in bomber number. Not even that can fix the situation as it does not take into account "attackers"
