82 and No. 110) received Vengeances in October 1942. The first dive bombing missions against Japanese forces were flown on 19 March 1943. A further two RAF squadrons in Burma received Vengeances, (No. 84 and No. 45), together with two squadrons of the Indian Air Force (IAF) (No. 7 and No. 8).In cases of heavy monsoon clouds, which obstructed the view during the dive, RIAF pilots practiced the unconventional method of shallow bombing, releasing bombs at 800 feet only. Enough hits were landed using this technique, that they were persuaded by commanders to use this technique when conditions were similar. Vengeances were heavily deployed in support of the second Arakan campaign of 1943/44, and defending against the Japanese attacks on Imphal and Kohima of April–July 1944. Following the successful defeat of the Japanese attack, the RAF and IAF started to phase out the Vengeance in favour of more versatile fighter bombers and twin-engine light bombers, with the last Vengeance operations over Burma being carried out on 16 July 1944. After Burma service, a detachment from 110 Squadron RAF was sent to Takoradi in West Africa via the Middle East, a number of aircraft breaking down en route. Between September and December 1944, 11 Vultees took part in air-spraying trials against malarial mosquitoes, using under wing spray dispensers. Although phased out of front line service with the RAF, Britain continued to receive large numbers of Vengeances, with bulk deliveries of Lend Lease aircraft (as opposed to those purchased directly by Britain) having only just started. Many of these surplus aircraft, including most Vengeance Mk IVs, were delivered to the UK and modified as target tugs, being used in that role both by the RAF and the Royal Navy's Fleet Air Arm (FAA). In those roles, all armament was removed from the aircraft. Australia Australia placed an order for 400 Vengeances as an emergency measure following the outbreak of war in the Pacific, which was met by a mixture of Lend Lease and diversions from the original British orders. While the first Vengeance was delivered to the Royal Australian Air Force (RAAF) in May 1942, the aircraft did not arrive in substantial numbers until April 1943. The RAAF's first Vengeance squadron, No. 12 Squadron flew its first operational mission against Selaru Island in the Dutch East Indies. Squadrons equipped with the Vengeance included Nos. 12, 21, 23, 24 and 25 Squadrons. Of
