The site was run by the United States Army Security Agency (ASA), the Army's signals intelligence branch closely allied with the National Security Agency. Its purpose was radio communications intercept and triangulation of enemy installations. The site was dominated by a large, circular Wullenweber array. In its heyday, the station housed 1,200 to 1,500 US personnel, complete with sleeping quarters, a cinema, a post exchange (PX), gym, swimming pool, tennis court, arms depot, and a 300 meter long tunnel that the Thai army today claims was used for electronic cable storage. It employed more than 1,400 Thais at generous wages. With the US pullout of Southeast Asia in 1975, the station was handed over to the Thai 3rd Infantry Division. In 1983, it became the base of the 1st Battalion, 13th Infantry Regiment. In August 1997, it was renamed "Sunthondhammathada Camp".{{cite news |last1=Nanuam |first1=Wassana |title=Ex-US base 'not secret prison' |url=https://www.bangkokpost.com/news/general/1528890/ex-us-base-not-secret-prison |accessdate=27 August 2018 |work=Bangkok Post |date=27 August 2018}} The station reemerged in news of the US War on Terror as some believe it to be the location of a US CIA "black site" used to interrogate suspected terrorists by the United States.{{cite news |title=Torture and secrecy in Thailand |url=http://www.abc.net.au/news/2018-03-15/torture-and-secrecy-in-thailand/9549064 |accessdate=27 August 2018 |work=Australian Broadcasting Corporation (ABC) |date=17 Mar 2018}}
