The F-105G Thunderchief is a single-engine, supersonic, long-range fighter-bomber. During the Vietnam War, the aircraft carried out more tactical airstrikes over North Vietnam than any other United States Air Force aircraft. It also suffered the greatest battle losses. It was used at Nellis AFB as training, testing, and “Wild Weasel” aircraft. The Mach 2 capable F-105 conducted the majority of strike bombing missions during the early years of the Vietnam War; it was the only U.S. aircraft to have been removed from combat due to high loss rates. Originally designed as a single-seat, nuclear-attack aircraft, a two-seat “Wild Weasel” version was later developed for the specialized Suppression of Enemy Air Defenses (SEAD) role against surface-to-air missile sites. The F-105G was also commonly called the “Thud” by its crews. Nellis AFB is known as the “Home of the Warfighter … Fly, Fight, Win.” A member of the U.S. Air Combat Command, fighter aircraft of all types can be found there. Air Force training is conducted in conjunction with air and ground units of the Army, Navy, Marine Corps, and air forces from allied nations.
