History:
Construction of Misawa Air Base (AB) began in May 1939 under the direction of the Imperial Japanese Naval Air Force. In September, construction began on a triangular runway network that included two 3,500 foot runways. However, plans to use Misawa as a long-range bomber base never materialized. It was used as a training and aeronautical research and development base. They used Lake Ogawara to train seaplane pilots and had a Kamikaze Corps stationed here, planning to land aircraft at American bases in the Pacific and conduct sabotage and demolition attacks. Carrier-based American F4Us attacked Misawa AB in July and August 1945 and destroyed more than 90 percent of the base. After the Japanese surrender on August 15, 1945, the base demobilized and the workers and military personnel dispersed across the region.
Just one month later the first American troops arrived at Misawa under the command of Captain Davis K. Stark, commander of the 32nd Army Engineering Construction Group. These troops secured the base and prepared it for the arrival of the 49th Fighter Group and its F-51 aircraft in 1948. The newly designated 49th Fighter Wing moved to Korea during the Korean War and returned to Misawa in 1953. The United States Air Force (USAF) Security Service assigned the 1st Radio Squadron (Mobile) to Misawa in January 1953, the first of several communications units on the base.
Over the next 21 years, eight different units acted as host unit on Misawa AB. A fire destroyed 434 buildings in Misawa City in 1966 and a major earthquake damaged both the city and the base in 1968. These events brought both communities closer together and led to increased cooperation.
Downsizing caused PACAF to leave Misawa in 1972 and the USAF Security Service’s 6920th Air Base Squadron (later Group) assumed host responsibilities. The U.S. Navy activated the Naval Security Group Misawa, here in July 1971 making it the oldest continuous American unit on Misawa (currently designated the Navy Information Operations Command Misawa). In 1978, the 6112th Air Base Group’s activation marked the return of PACAF units to Misawa.
In July 1984, the 432d Tactical Fighter Wing became the host unit and remained as host until the 35th Fighter Wing activated on October 1, 1994.
Current tenant units include the Naval Air Facility Mi- sawa; elements of the US Navy’s Commander, Task Force 72/57, U.S. Navy Information Operations Command Misawa; the 373d Intelligence Group, the U.S. Army’s 403d Military Intelligence Detachment, and the US Army’s Joint Tactical Ground Station.
