Throughout the 1990s and more recently, "Nimitz"-class carriers have been deployed as part of humanitarian missions. While deployed in the Gulf War, "Abraham Lincoln" was diverted to the Pacific Ocean to participate alongside 22 other ships in Operation Fiery Vigil, evacuating civilians following the eruption of Mount Pinatubo on Luzon Island in the Philippines. In October 1993, "Abraham Lincoln" deployed to Somalia to assist UN humanitarian operations there, spending four weeks flying patrols over the area around Mogadishu while supporting U.S. troops during Operation Restore Hope. The same ship also participated in Operation Vigilant Sentinel in the Persian Gulf in 1995.
