Tarawa-class Amphibious Assault Ship

The Tarawa-class is a ship class of amphibious assault ships/LHA operated by the United States Navy (USN). Five ships were built by Ingalls Shipbuilding between 1971 and 1980; another four ships were planned, but later canceled. As of 2011, only one vessel is active, and the class is due to be replaced by the America-class amphibious assault ships from 2013 onwards. In the late 1970s, the Shah of Iran considered purchasing two Tarawa-class LHAs for the Imperial Iranian Navy.
