conflict in which the United States has been involved, officially and unofficially, since the end of the Vietnam War. In July 1979, AC-130H crews deployed to Howard Air Force Base, Panama, as a precaution against possible hostile actions against American personnel during the Nicaraguan Revolution. New time aloft and nonstop distance records were subsequently set by a 16th SOS two-ship AC-130H formation flight that departed Hurlburt Field on 13 November 1979 and landed on 15 November at Andersen Air Force Base, Guam, a distance of and 29 hours 43 minutes nonstop, refueling four times in-flight. Refueling support for the Guam deployment was provided by KC-135 crews from the 305th Air Refueling Wing from Grissom AFB, Indiana. In November 1979, four AC-130H gunships flew nonstop from Hurlburt Field to Anderson AFB, Guam, because of the hostage situation at the US Embassy in Iran. At Guam, AC-130H crews developed communications-out/lights-out refueling procedures for later employment by trial-and-error. This deployment with the 1 SOW/CC as task force commander was directed from the office of the CJCS for fear that Iranian militants could begin executing American Embassy personnel who had been taken hostage on 4 November. One early option considered AC-130H retaliatory punitive strikes deep within Iran. Later gunship flights exceeded the 1979 Hurlburt-to-Guam flight. Upon return in March 1980, the four planes soon found themselves in Egypt to support the ill-fated hostage rescue attempt. During Operation Urgent Fury in Grenada in 1983, AC-130s suppressed enemy air-defense systems and attacked ground forces enabling the assault of the Point Salines Airfield via airdrop and air-land of friendly forces. The AC-130 aircrew earned the Lieutenant General William H. Tunner Award for the mission. The AC-130Hs of the 16th Special Operations Squadron unit maintained an ongoing rotation to Howard AB, Panama, monitoring activities in El Salvador and other Central American points of interest, with rules of engagement eventually permitting attacks on FMLN targets. This commitment of maintainers and crews started in 1983 and lasted until 1990. The AC-130 is considered to have hastened the end of the Salvadoran Civil War in the 1980s. Crews flew undercover missions from Honduras and attacked guerrilla camps and concentrations. AC-130s also had a primary role during the United States invasion of Panama (named Operation Just Cause) in 1989, when they destroyed Panama Defense Force headquarters and numerous command-and-control facilities, and provided close air support for US ground troops.
