The Lockheed PV-1 Ventura was developed as a result of an agreement between the Navy and the USAAF in mid 1942. The Navy was looking for an aircraft to fill the role of a long range, land based reconnaissance and patrol aircraft that could carry a substantial bomb payload.
Lockheed was producing a version designated as the B-34/B-37 Ventura.
In 1942, the Navy version began production at the Lockheed Vega plant in Burbank, California and would be designated as the PV-1 Ventura.
The first PV-1 flew on November 3, 1942. The Navy received its first Ventura in December of 1942. They began Naval service on February 1, 1943.
The first squadron to receive the new PV-1 was VB-127 stationed at NAS Deland, Florida.
The PV-1 saw its first combat duty in the Aleutians in April 1943 assigned to VP-135. They conducted reconnaissance patrols and strikes against the Japanese islands in the Kurile chain.
The PV-1 also served for a short time as a Marine Corps night fighter assigned to VMFA(N)531 operating in the Solomon Islands in September 1943.
PV-1 Venturas also served in the RAF, the RNZAF, and the South African Air Force.
