In the summer of 1971, Guam was chosen as a test vessel for Admiral Elmo Zumwalts Sea Control Ship concept. This ship was to operate a few VSTOL fighters and some ASW helicopters in order to free up supercarriers from convoy duty during a conflict with the Soviet Union. On 18 January 1972, she began extensive testing and in 1974 deployed in the Atlantic as a sea control ship with Marine Corps AV-8A Harrier VSTOL fighters and Sea King ASW helicopters. Guam completed the SCS tests and reassumed her role as an Amphibious Assault Ship on 1 July 1974.
