A development of the successful Lockheed 'medium twins' of the late 1930s, the PV Ventura/Harpoon family of patrol bombers saw widespread service with both the US Navy/Marine Corps and the TAF and Commonwealth from October 1942 onwards. The USAAF also used surplus Venturas originally ordered by the RAF, designated B-34 Lexingtons, in the bomber training and coastal patrol roles. The final variant in this family was the larger PV-2 Harpoon, which was built to a US Navy requirement from March 1944 onwards. Used primarily in the Pacific, 470 Harpoons saw frontline service on anti-shipping and submarine patrols through to VJ-Day. This book covers each of these variants in complete illustrated detail.
