Yankee Station was a fixed coordinate off the coast of Vietnam where U.S. Navy aircraft carriers and support ships loitered in open waters. Starting in April 1964, it was initially located at 16 degrees North latitude, 110 degrees East longitude. However, with a massive increase in operations over North Vietnam in 1966, the military moved Yankee station about 145 miles northwest. During the Vietnam War, Yankee Station served as a launch site for air strikes over North Vietnam where the aircraft carriers of Task Force 77 played a leading role in these strikes.
