Cleveland class

USS Dubuque (LPD-8)
Class overview
Name	Cleveland-class amphibious transport dock
Preceded by	Austin-class amphibious transport dock
Succeeded by	Trenton-class amphibious transport dock
Completed	Cleveland, Dubuque, Denver, Juneau, Coronado, Shreveport, Nashville

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.

Trenton class

USS Trenton (LPD-14)
Class overview
Name	Trenton-class amphibious transport dock
Operators	United States Navy Indian Navy
Preceded by	Cleveland-class amphibious transport dock
Succeeded by	San Antonio-class amphibious transport dock
Completed	Trenton, Ponce

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.

A recent check of the above mentioned site Naval Vessel Registry lists the USS Trenton and the USS Ponce as Austin class amphibious transport dock.[1]
