Now the Harpoon could also carry two “Tiny Tim” rockets completely enclosed. The bomb load capacity was increased 30% on the PV-2 to 4,000 lbs., leading to a redesign of the bomb bay doors giving the PV-2 a distinctive “bulge” on the underside. 50 inch guns in the rear ventral position. 50 inch guns in the dorsal turret, and two. Along with the forward guns the PV-2 also carried two. 50 inch machine guns in the upper nose decking, and 3 fixed. The forward guns were increased from three on the PV-1 to five on the 2’s 2 fixed.
Unfortunately, speed statistics were projected lower than the PV-1 due to the use of the same engines but an increase in weight, but was expected to have increased range and better takeoff characteristics. To try and improve the take-offs on the PV-2 the wing area increased from 551ft2 to 686 ft2, and the wingspan increased by 6 feet 6 inches to 75 feet, to increase the load-carrying capability. of bombs, all of which was changed on the PV-2 Harpoon. Also, the later production PV-1’s had 3 machine guns under the nose, and could carry approximately 3,100 lbs.

The “V” in PV-2 stood for “Vega” Aircraft Company, a division of Lockheed that built the Ventura’s. Shortly thereafter, the US Army Air Force turned over exclusive use of the Ventura to the US Navy, so came the PV-1 Ventura. The O-56 was redesignated the RB-34B (RB-Reconnaissance Bomber), but before even one took flight, it was renamed again the B-37. The main difference between the O-56 and the Ventura was the engines, dropping the horsepower on the Ventura from 2,000 P&W R-2800 radials to 1,700 on Wright R-2600-13 radials on the O-56.
In 1941 large orders were placed for armed reconnaissance versions of the Ventura designated O-56.
