These ships were converted from amphibious warships for employment as command ships. Amphibious warships are uniquely designed to support assault from the sea against defended positions ashore. They must be able to sail in harm's way and provide a rapid built-up of combat power ashore in the face of opposition. The United States maintains the largest and most capable amphibious force in the world.
Command ships provide communications and accommodations for fleet commanders and staff. Ships are equipped air and surface radars, helicopter, chaff launchers and an electronic warfare suite.
