The fourth U.S. Navy warship to carry the name Mississippi was a Virginia-class nuclear-powered missile cruiser, the USS Mississippi CGN-40, at the time, the world’s most advanced. Commissioned in 1978, she served in the Mediterranean during the Gulf of Sidra confrontation with Libya, and later, she deployed with the USS John Kennedy Battle Group to support Operation Desert Shield in 1990. After 18 years service and five Battle Efficiency Awards, the USS Mississippi was decommissioned in 1996. Her ship's bell can be seen in the gardens at Rosalie Mansion, on the site of Fort Rosalie overlooking the Mississippi River.
