USS Guadalcanal (LPH-7), the third Iwo Jima-classamphibious assault ship (helicopter), was launched by the Philadelphia Naval Shipyard 16 March 1963, sponsored by Zola Shoup, wife of General Shoup, the former Commandant of the Marine Corps; and commissioned 20 July 1963, Captain Dale K. Peterson in command. It was the second ship in the Navy to bear the name.
Upon completion of sea trials and outfitting, Guadalcanal departed Philadelphia to join the Amphibious Forces, U.S. Atlantic Fleet. One of a new class of ships designed from the keel up to embark, transport, and land assault marines by means of helicopters, she lent new strength and flexibility to amphibious operations. After departing Norfolk 23 October 1963 for six weeks’ shakedown training at Guantanamo Bay, Cuba, Guadalcanal steamed to Onslow Beach, North Carolina, 6 December for practice amphibious landings. She then carried on training and readiness operations with the Atlantic Fleet, based in Norfolk until departing for Panama 11 February 1964. Following 2 months on station as flagship for Commander PhibRon 12 with the 12 Marine Expeditionary Unit embarked and ready to land anywhere needed. Guadalcanal entered Philadelphia Naval Shipyard 26 May, but was deployed again 7 October as a unit of Operation “Steel Pike 1”, a NATO landing exercise on the beaches of southern Spain.
Career highlights include 21 July 1966, when she recovered the Gemini X astronauts and their spacecraft after they landed in the Atlantic east of Cape Kennedy, and 13 March 1969, when she recovered the Apollo 9 capsule and crew off the Bahamas. In October 1985 the ship logged its 100,000th aircraft landing.
In 1987 Guadalcanal was leading minesweeping operations in the Persian Gulf when she encountered Iran Ajr laying mines in the shipping lanes. Helicopters from Guadalcanal attacked the ship; troops from Guadalcanal boarded and captured the ship. (Iran Ajr was the second enemy warship captured on the high seas by the U.S. Navy since 1815; the first was the German submarine U-505, captured in 1944 by the first USS Guadalcanal, an escort carrier.) Guadalcanal also provided the Marines for the first wave of Operation Provide Comfort, the Kurdish relief operations in Northern Iraq immediately following the Persian Gulf War in 1991.
Guadalcanal was decommissioned in 1994, and stored as part of the James River Reserve Fleet until she was used as a target and sunk in the Virginia Capes area on 19 May 2005.
