The 4th Reconnaissance Group was the only reconnaissance unit to serve with the Thirteenth Air Force and took part in the advance across the southern Pacific, moving from its early bases on New Caledonia to Morotai in the Moluccas Islands, an advance of around 3,000 miles.
The group performed a wide range of reconnaissance duties. It was used on standard reconnaissance duties over Japanese held territory, searching for targets and producing post-bombing damage assessment, but was also used as a mapping unit, both over Japanese and Allied held territory and to produce navigation charts for the often poorly mapped waterways in the area.
The group was based on New Caledonia from November 1942 until January 1943, before moving north to Espiritu Santo in the New Hebrides, where it remained until May 1944. At this stage in the war its targets were mainly in the Solomon Islands (including Guadalcanal) and New Guinea.
The group moved onto Guadalcanal in May 1944 and was based there until December 1944. This allowed it to extend its range to the west, ranging across the Bismarck Archipelago (north-west of the Solomon Islands) and further west along New Guinea.
The final wartime move came in December 1944 when the group moved west to Morotai in the northern Moluccas Islands. This allowed it to extend its operations into the Western Pacific. In the last three months of the war it also operated over Mindanao and Borneo, supporting some of the final battles on those islands.
The group moved to Leyte in September 1945 and was inactivated there on 15 January 1945.
