Some of the delivered PV-2s had a limited armament of five machine guns in the nose and received an other designation, PV-2D. This problem was soon solved and the aircraft already in use could be modified with reinforcements. The 30 PV-2's already delivered received the designation PV-2C and were use for training purposes only, because the wing tanks could not be used.Īlso the skin might wrinkle under certain flying conditions, so limitations of the diving angle and maximum speed were ordered. Soon problems occurred with the self sealing tanks in the wings. The first of this new order was delivered in March 1944. The Navy accepted the airplane and ordered for 300 examples. Spring 1943 the new aircraft was handed over to the US Navy under the designation PV-2. 50 machine guns plus two moveable machine guns in a turret.ĭue to the larger weight of the new plane its maximum speed was about 20 - 30 mph lower than the speed of the Ventura (because the same engines were used). The armament was extended to eight fixed forward firing.Involving this modification the exhaust become longer and ended under the wing. The engine exhaust (inclusive interior heating system) where changed.The interior was revised, so windows were re-located.The canopy was change, to improve the sight for the crew.Larger bomb space, so two, in stead of one ‘Tiny Tim’ rockets could be carried.To keep the plane manoeuvrable with the enlarged wing, de tail was redesigned and enlarged.Īlso the tail end was enlarged, thus improving the handling on the ground.įurthermore some smaller improvements and changes were added: Modifications of the PV-1 to get a PV-2įirst the wing span was enlarged from 65 foot, 6 inch to 75 foot, so the internal fuel load was increased from 1345 to 1863 US Gallon and the wing load was lowered. Soon after the introduction of the PV-1 a team started with the development of the PV-2 harpoon, which would better comply with the needs of the US Navy. For long distance missions two non self sealing fuel tanks of 200 gallon each were added and also two 165 gallon drop tanks could be carried under the wings. Also the range for the Ventura was to small for operational use in the Pacific area. This was caused by its descent from the Lockheed Model 18. The PV-1’s didn't have the glass nose configuration like the British Ventura's, but a solid nose, with ASD-1 radar.Ī negative point was the rather small bomb compartment and the fact that there were only three position for placing bomb racks under the wings. Some of the almost 700 ordered Ventura’s went to the US.Navy under the designation PV-1 (1 = First V = Vega-produced P= Patrol-type). This type was ordered by the British in 1940 to replace the Hudson and the Bristol Blenheim and was developed from the civil Lockheed Model 18 Lodestar. ![]() It was likely to be based upon an existing type, such as the Lockheed (Vega) Model 37 Ventura. Early 1942 the US navy needed a fast maritime patrol aircraft.
