An amphibious transport dock, also called a landing platform/dock (LPD), is an amphibious warfare ship, a warship that embarks, transports, and lands elements of a landing force for expeditionary warfare missions. Several navies currently operate this kind of ship. The ships are generally designed to transport troops into a war zone by sea, primarily using landing craft, although invariably they also have the capability to operate transport helicopters.
Amphibious transport docks perform the mission of amphibious transports, amphibious cargo ships, and the older LSDs by incorporating both a flight deck and a well deck that can be ballasted and deballasted to support landing craft or amphibious vehicles. The main difference between LSDs and LPDs is that while both have helicopter landing decks, the LPD also has hangar facilities for protection and maintenance. In the United States Navy, the newer class of LPD has succeeded the older classes of LSDs, and both the Navy and U.S. Marine Corps are looking to the LPD to be the basis of their new LX(R) program to replace their LSDs.

The United States Navy has approximately 480 ships in both active service and the reserve fleet, with approximately 70 more in either the planning and ordering stages or under construction, according to the Naval Vessel Register and published reports. This list includes ships that are owned and leased by the U.S. Navy; ships that are formally commissioned, by way of ceremony, and non-commissioned. Ships denoted with the prefix "USS" are commissioned ships. Prior to commissioning, ships may be described as a "pre-commissioning unit" or PCU, but are officially referred to by name with no prefix. US Navy support ships are often non-commissioned ships organized and operated by Military Sealift Command. Among these support ships, those denoted "USNS" are owned by the US Navy. Those denoted by "MV" or "SS" are chartered.
Current ships include commissioned warships that are in active service, as well as ships that are part of Military Sealift Command, the support component and the Ready Reserve Force, that while non-commissioned, are still part of the effective force of the U.S. Navy. Future ships listed are those that are in the planning stages, or are currently under construction, from having its keel laid to fitting out and final sea trials.
There exist a number of former US Navy ships which are museum ships (not listed here), some of which may be US government-owned. One of these, USS Constitution, a three-masted tall ship, is one of the original six frigates of the United States Navy. It is the oldest naval vessel afloat, and still retains its commission (and hence is listed here), as a special commemoration for that ship alone.List of ship commissionings in 2007

A Naval Inactive Ship Maintenance Facility (NISMF) is a facility owned by the United States Navy as a holding facility for decommissioned naval vessels, pending determination of their final fate. All ships in these facilities are inactive, but some are still on the Naval Vessel Register (NVR), while others have been struck from that Register.
The ships that have been stricken from the NVR are disposed of by one of several means, including foreign military sale transfer, ship donation as a museum or memorial, domestic dismantling and recycling, artificial reefing, or use as a target vessel. Others are retention assets for possible future reactivation, which have been laid up for long-term preservation and are maintained with minimal maintenance (humidity control, corrosion control, flood/fire watch) should they need to be recalled to active duty.
The Navy has been reducing the number of inactive ships, which numbered as many as 195 in 1997, but was down to 49 by the end of 2014.The Naval Sea Systems Command's Inactive Ships Management Office (INACTSHIPOFF) is based in Portsmouth, Virginia.There are NISMFs in:
Pearl Harbor, Hawaii
Philadelphia, Pennsylvania,In addition, parts of Norfolk Naval Shipyard and Puget Sound Naval Shipyard are designated for the storage of inactive nuclear powered vessels.
Inactive ship facilities in Suisun Bay, James River and Beaumont, Texas are owned and operated by the Maritime Administration under the U.S. Department of Transportation.Raleigh-class amphibious transport dock
The Raleigh class of amphibious transport docks served the United States Navy.San Antonio-class amphibious transport dock
The San Antonio class is a class of amphibious transport docks, also called a "landing platform, dock" (LPD), used by the United States Navy. These warships replace the Austin-class LPDs (including Cleveland and Trenton sub-classes), as well as the Newport-class tank landing ships, and the Charleston-class amphibious cargo ships that have already been retired.Twelve ships of the San Antonio class were proposed, but only eleven were funded. Their original target price was $890 million; as built, their average cost is $1.6 billion. Defense Authorization for Fiscal Year 2015 included partial funding for a twelfth San Antonio-class ship. As of January 2018 eleven warships of this class are in service with the U.S. Navy with an additional two ships under construction or authorized.San Giorgio-class amphibious transport dock
The San Giorgio class is an amphibious assault ship, a type of helicopter carrier, of the Italian Navy. These ships can carry a battalion of troops, and up to 36 armored vehicles. The stern floodable dock can accommodate three landing craft. The ships are based at the Brindisi naval base on the Adriatic coast.
San Giorgio and San Marco have been extensively modified into landing helicopter docks. They accommodate a full-length flight deck with four landing spots. San Giusto, the third vessel, has not been modified since construction, however featured an improved design, and is normally employed as a training ship.Type 071 amphibious transport dock
