[[File:Lockheed Ventura Mk I of No. 21 Squadron RAF at Methwold, Norfolk, 27 February 1943. CH8885.jpg|thumb|An RAF Ventura Mk 1]]
At the start of the war, Lockheed proposed military conversions of the Lodestar for the RAF as replacement for the Hudson reconnaissance aircraft and the [[Bristol Blenheim]] bomber. The first British order was placed in February 1940 for 25 Model 32 as bombers.
The Ventura was very similar to its predecessor, the [[Lockheed Hudson]]. The primary difference was not in layout; rather, the Ventura was larger, heavier, and used more powerful engines than the Hudson. The RAF ordered 188 Venturas in February 1940, which were delivered from mid-1942. Venturas were initially used for daylight raids on occupied Europe but, like some other RAF bombers, they proved too vulnerable without fighter escort, which was difficult to provide for long-range missions. Venturas were replaced by the faster [[de Havilland Mosquito]]. The Venturas were transferred to patrol duties with [[Coastal Command]] as the Mosquito replaced them in bomber squadrons; 30 went to the [[Royal Canadian Air Force]] (RCAF) and some to the [[South African Air Force]] (SAAF). The RAF placed an order for 487 '''Ventura Mark II'''s but many of these were diverted to the USAAF, which placed its own order for 200 '''Ventura Mark IIA''' as the '''B-34 Lexington''', later renamed '''RB-34'''.

[[File:Lockheed Ventura.jpg|thumb|A PV-1 Ventura]]
The '''PV-1 Ventura''', built by the Vega Aircraft Company division of Lockheed (hence the "V" Navy manufacturer's letter that later replaced the "O" for Lockheed), was a version of the Ventura built for the U.S. Navy (see [[#United States Navy|Venturas in U.S. Navy service]] below). The main differences between the PV-1 and the B-34 were the inclusion of special equipment in the PV-1, adapting it to its patrol bombing role. The maximum fuel capacity of the PV-1 was increased from 1,345 gal (5,081
Early production PV-1s still carried a bombardier's station behind the nose radome, with four side windows and a flat bomb-aiming panel underneath the nose. Late production PV-1s dispensed with this bombardier position and replaced it with a pack with three 0.50 inch (12.7 mm) machine guns underneath the nose. These aircraft could also carry eight 5-inch (127 mm) [[HVAR]] rockets on launchers underneath the wings.

The squadron was told that the target was of such importance to Dutch morale, that the attack was to be continued regardless of opposition. Significant problems developed with rendezvousing with the escorting fighters, with the result that all 10 Venturas that crossed the coast were lost to German fighters. Squadron Leader [[Leonard Trent]] (later the last of [[Stalag Luft III#The
The Ventura was never very popular among RAF crews. Although it was {{convert|50|mph|km/h|abbr=on}} faster and carried more than twice the bomb load of its predecessor, the [[Lockheed Hudson|Hudson]], it proved unsatisfactory as a bomber. By the summer of 1943, the Ventura had been replaced by the de Havilland Mosquito. The last Ventura raid was flown by 21 Squadron on 9 September 1943. Some Venturas were modified to be used by Coastal Command as the '''Ventura G.R.I.''' and 387 PV-1s were used by the RAF as the '''Ventura G.R.V''' in the Mediterranean and by Coastal Command. Some RAF aircraft were modified into '''Ventura C.V''' transport aircraft. A small number of Venturas were also used in other air forces, including the RCAF, RNZAF and SAAF.

In the United Kingdom, [[No. 464 Squadron RAAF]] formed (
In Australia, 55 PV-1s were supplied to the RAAF for use in the [[South West Pacific Area]]. [[No. 13 Squadron RAAF]] was the only operational squadron in Australia equipped with the Ventura. It operated primarily in north-eastern [[Queensland]] and then the [[Northern Territory]], and later serving in the [[Borneo campaign (1945)|Borneo campaign of 1945]]. After the war, the squadron used its aircraft to help transport liberated [[Prisoner of war#Empire of Japan|prisoners of war]].
Line 122:
The first 19 RB-34s that arrived by sea from the U.S. in June had much equipment either missing or damaged. Six airworthy machines were hurriedly produced by cannibalization and sent into action with [[No. 3 Squadron RNZAF]] in [[Fiji]]. On 26 June the first PV-1s were flown to [[Whenuapai]] and [[No. 1 Squadron RNZAF]] was able to convert to 18 of these by 1 August, then replacing the mixed 3 Squadron in action at [[Henderson Field (Guadalcanal)|Henderson Field]], [[Guadalcanal]] in late October.
By this time [[No. 2 Squadron RNZAF]] at [[Ohakea]] and [[No. 9 Squadron RNZAF]] were also using the type. The following year [[No. 4 Squadron RNZAF]] and [[No. 8 Squadron RNZAF]] also received Venturas. Some squadrons were retained on ''garrison'' duty while others followed the allied advance to [[Emirau]] and [[Green Island, Papua New Guinea|Green Island]] and to [[New Britain]]. RNZAF Venturas were tasked with routine patrols, anti-shipping strikes, minelaying, bombing and strafing missions, [[air-sea rescue]] patrols, and photographic reconnaissance missions
RNZAF machines often clashed with Japanese fighters, notably during an air-sea rescue patrol on Christmas Eve 1943. NZ4509 was attacked by nine Japanese single-

Planned re-equipment with de Havilland Mosquitos did not take place until after the cessation of hostilities. The last Ventura unit was No. 2 Squadron, which continued to operate PV-1 and PV-2 aircraft on meteorological duty until 1948. A restored RNZAF RB-34 (NZ4600) is owned by the [[Museum of Transport and Technology]] in [[Auckland]].
