The Austin class of amphibious transport dock followed the Raleigh class and was followed by the San Antonio class. Note that some sources consider Cleveland (seven built) and Trenton (two built) ships to be a part of the Austin class, but the Naval Vessel Registry lists them as a separate class.

The Cleveland class of amphibious transport dock was a refinement of the Austin class. All earlier classes are being replaced by the San Antonio class.

The Cleveland class was originally to consist of 10 ships, LPD-7 through LPD-16. Seven ships were actually completed and listed in this class, with one being converted to a command ship, Coronado (AGF-11). Trenton (LPD-14) and Ponce (LPD-15) were originally to be included in the Cleveland class, but were completed as almost identical Trenton-class LPDs. The most noticeable difference between the Cleveland and Austin classes is the extra level in the superstructure housing a flag bridge and command and control facilities for an embarked staff which the earlier ships lack.

The Trenton class of amphibious transport dock was a refinement of the Austin and Cleveland classes. Note that some sources consider Cleveland and later ships to be a part of the Austin class, but the Naval Vessel Registry lists them as a separate class. All earlier classes are being replaced by the San Antonio class. LPD-16, while authorized, was cancelled before being constructed.
