Air Force EICAP (heavy aircraft advanced training unit) was transferred to Lajes, operating Douglas C-47, Douglas C-54 and later CASA C-212 Aviocar. During the Portuguese Colonial War, from 1961 to 1975, the Air Force Hospital at Lajes operated as the main centre for treatment and rehabilitation of mutilated and heavy burned soldiers of the three services of the Portuguese Armed Forces. During the 1973 Yom Kippur War, Lajes Field also supported Operation Nickel Grass U.S. airlift missions to Israel, highlighting the importance of the U.S. Air Force base at Lajes. Another important Cold War operation at Lajes was the U.S. Navy's Naval Air Facility Lajes (NAF Lajes), a tenant activity at the air base. NAF Lajes, and its associated Tactical Support Center (TSC)/Antisubmarine Warfare Operations Center (ASWOC), supported rotational detachments of U.S. Navy P-2 Neptune and later P-3 Orion maritime patrol aircraft that would track Soviet attack, guided missile, and ballistic missile submarines in the region. With the collapse of the Soviet Union and the Warsaw Pact, and end of the Cold War, P-3 operations at Lajes declined, and the Naval Air Facility was inactivated in the late 1990s. Post-Carnation Revolution Following the Portuguese Air Force reorganization of 1978, Lajes Air Base comes to have two resident flying units: Squadron 503 - equipped with CASA C-212 aircraft and Squadron 752 - equipped with Aérospatiale SA 330 Puma helicopters. In 1980, a detachment of Squadron 301 - equipped with Fiat G.91 fighter-bombers - starts to be based at Lajes, this being augmented and becoming Squadron 303 "Jaguares" in 1981. The Azores Islands earthquake affected Terceira Island. Damage to Lajes Field was minimal, but Portuguese communities throughout the island suffered extensive damage. Military personnel responded with food, shelter, equipment, and manpower. In the summer of 1984, Lajes undertook a new mission known as "SILK PURSE." Boeing EC-135s began operating out of Lajes Field as an airborne command post for the U.S. Commander-in-Chief, Europe. Along with the aircraft came the U.S. European Command battle staff and flight crews from United States Air Forces in Europe. This mission was ended in late August 1991. In 1990, Squadron 303 was disbanded. Lajes supported the large airlift during the Gulf War. On the first day of the deployment over 90 aircraft transited Lajes. Strategic Air Command (SAC) created a provisional tanker wing, the 802nd Air Refueling Wing (P) Provisional, at Lajes to support the airlift. At
