Yankee Station (officially Point Yankee) was a fixed coordinate off the coast of Vietnam where U.S. Navy aircraft carriers and support ships operated in open waters over a nine-year period during the Vietnam War. The location was used primarily by aircraft carriers of Task Force 77 to launch strikes over North Vietnam. While the coordinate's official designation was "Point Yankee", it was universally referred to as Yankee Station. Carriers conducting air operations at Yankee Station were said to be "on the line" (in combat) and statistical summaries were based on days on the line. Yankee Station was initially located at 16° 00′ N, 110° 00′ E, however with a massive increase in operations over North Vietnam in 1966 the station was moved about 145 miles (230 km) northwest to 17° 30′ N, 108°
