"Peleliu" deployed again to the Western Pacific in January 1990. The ship, along with her Amphibious Ready Group (ARG), participated in multinational exercises including Exercise Team Spirit with forces from the Republic of Korea, and Exercise Cobra Gold, in Thailand. "Peleliu" returned home to Naval Station Long Beach in July and later that summer entered the shipyard for an availability period that was scheduled to last nearly a year. The U.S. response to the Iraqi invasion of Kuwait in August 1990 curtailed the shipyard availability and forced "Peleliu" into an accelerated schedule of pre-deployment training, but she did not deploy for Operation Desert Shield/Desert Storm. She eventually departed Long Beach in May 1991, in support of ongoing U.S. operations in the Middle East. In June 1991, while en route to the Persian Gulf, she was diverted from a scheduled port call in Hong Kong to the Philippines, where she participated in the evacuation of the Americans from the Naval Base Subic Bay following the volcanic eruption of Mount Pinatubo. This evacuation included taking most of the patients from the maternity ward at the Subic Bay naval hospital, and hence there were several births on board. This eruption was one of the largest of the past 100 years and covered a large region of the Philippines in volcanic ash and caused extensive damage to American military bases in the area, including Naval Station Subic Bay, Naval Air Station Cubi Point, and Clark Air Force Base.
