TAIU-SWPA (Technical Air Intelligence Unit–South West Pacific Area) was the first of the Technical Air Intelligence Units formed during World War II to recover Japanese aircraft to obtain data regarding their technical and tactical capabilities.
TAIU-SWPA was originally formed as ATAIU in November 1942 as a joint venture by the United States Navy (USN), the United States Army Air Forces (USAAF), the Royal Australian Air Force (RAAF) and the British Royal Navy at Hangar 7 of Eagle Farm Airbase, Brisbane, Queensland, Australia. Aircraft tested at Hangar 7 of Eagle Farm Airbase carried a 'XJ' code. Known used codes are XJ001 till XJ005, preceding those used later in the Philippines.
In mid-1944, the US Navy personnel were withdrawn from the TAIU and reassigned to Naval Air Station Anacosta (NAS Anacosta), to form the Technical Air Intelligence Centre (TAIC) to centralise and co-ordinate the work of test centers in the United States with the work of TAIUs in the field. The original unit was then renamed TAIU for the South West Pacific Area (TAIU-SWPA).
By the time of the invasion of the Philippines, Technical Air Intelligence operations in the South-West Pacific Area were fully developed. Considerable instructions were given to the troops in the field on the equipment likely to be found and the importance of its preservation. After the liberation of the Philippines, in early 1945, TAIU-SWPA was moved from Australia to Clark Field in the Philippines and there it gained an appreciation of the state of the enemy's technological and economic development, essential to the build-up for the planned invasion of Japan.
