military air defense identification zone (ADIZ). US Navy era (1960s–2000s) The United States Navy assumed the responsibility of running the air station from MATS in 1961. In 1974, the left-wing Government of Iceland's new proposal to close the base triggered a petition that garnered 55,000 signatures, about a quarter of the population of the entire nation. This led to the ruling coalition collapsing and the 1974 Icelandic parliamentary election being held. On 1 October 1979 Tactical Air Command (TAC) absorbed ADC's assets, and the F-4E Phantom II aircraft of the 57th Fighter Interceptor Squadron (57 FIS). In July 1985, F-15Cs and F-15Ds replaced the aging F-4s, and the tail code "IS" was assigned to Air Forces Iceland (AFI). During the height of the Cold War in the 1980s, Keflavik also hosted rotational E-3 Sentry AWACS aircraft and KC-135 Stratotanker aircraft from CONUS to support the air defense mission and rotational HC-130 Hercules aircraft from RAF Woodbridge from the 67th Aerospace Rescue and Recovery Squadron to support their detachment of Keflavik-based HH-3 Jolly Green Giant and later HH-60G Pave Hawk helicopters in their search and rescue mission. Beginning in 1984, the 932d Air Control Squadron established a Radar Operations Control Center at Keflavik which coordinated the 57th FIS interceptors to contacts passing through the GIUK gap. It received long-range radar inputs from five radar sites: the four sites in Iceland plus a data-tie from the Tórshavn AS radar in the Faroe Islands. Tórshavn was located atop mount Sornfelli. The ROCC remained active until the turnover of the facility in 2006. Air Forces Iceland continued the air defense mission of Iceland as a tenant organization at Keflavik. Under ADC until 1979 and under TAC until 1992. On 1 June 1992, Air Combat Command (ACC) assumed command and control of AFI and the 57 FIS. Less than a year later, the 57 FIS was redesignated as the 57 Fighter Squadron (57 FS) and reassigned to the 35th Fighter Wing that was transferred from the closing George AFB, California. On 1 October 1994, the 35th Wing was inactivated at Keflavik and reactivated that same day at Misawa Air Base in Misawa, Japan. The 35th Wing was replaced by the newly activated 85th Wing. On 1 March 1995, the 57th FS was inactivated and the interceptor force was replaced by Regular Air Force and Air National Guard F-15 Eagle fighter aircraft rotating every 90 days
