4th Reconnaissance Group
# 4th Reconnaissance Group

The 4th Reconnaissance Group is an inactive United States Air Force unit. It was last assigned to Thirteenth Air Force and was stationed at Clark Field, Philippines. It was inactivated on 15 January 1946.

The unit operated P-38/F-4 Lightning photo-reconnaissance aircraft in the Pacific Theater of World War II over a wide area. The group, based successively on New Caledonia, Espiritu Santo, Guadalcanal, and Morotai, flew reconnaissance missions over enemy territory to supply air force units with target and damage- assessment photographs and to provide army and navy units with intelligence on Japanese troop concentrations, installations, shore defenses, supply routes, and shipping. It also produced maps of Allied and enemy-held territory and prepared navigation charts for US units.

During the last three months of the war the group photographed Japanese positions and installations on Mindanao and Borneo to aid US and Australian operations.
