USS Guam (LPH-9), was an Iwo Jima-class amphibious assault ship, and was laid down by the Philadelphia Naval Shipyard on 15 November 1962; launched on 22 August 1964, sponsored by Mrs. Vaughn H. Emory Green, and commissioned on 16 January 1965. She was the third US Navy ship to carry the name, after the US Territory of Guam.
From 16 to 28 February 1966, Guam patrolled south of the Dominican Republic ready to land forces on the volatile island of Hispaniola if necessary. She conducted amphibious exercises until entering Philadelphia Naval Shipyard on 1 June 1966 for post shakedown availability.
She departed Philadelphia on 2 August 1966 and prepared for service as the primary recovery ship for the Gemini 11 space flight. On 15 September, at 0959 EDT, Guam recovered Astronauts Pete Conrad and Dick Gordon 710 miles (1,140 km) east of Cape Kennedy. From 28 November to 12 December, Guam participated in Exercise "Lantflex 66", and on the latter date became flagship of Amphibious Squadron 8 and Caribbean Amphibious Ready Group.

In the summer of 1971, Guam was chosen as a test vessel for Admiral Elmo Zumwalt's 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. In October 1974 her aircraft complement, operated by the US Marine Corps, comprised six AV-8A, eight CH-46F Sea Knights, five CH-53D Sea Stallions and two Bell UH-1N Iroquis utility helicopters.
