An amphibious transport dock, also called a landing platform dock (LPD), [1] is an amphibious warfare ship, a warship that embarks, transports, and lands elements of a landing force for expeditionary warfare missions. [2] 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 dock landing ships (LSD) 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. [3] In the United States Navy, the newer class of LPD has succeeded the older classes of LSDs, and both the Navy and United States Marine Corps are looking to the LPD to be the basis of their new LX(R) program to replace their LSDs. [4]

<span class="mw-page-title-main">Amphibious assault ship</span> Type of warship used in amphibious assaults

An amphibious assault ship is a type of amphibious warfare ship employed to land and support ground forces on enemy territory during an amphibious assault. The design evolved from aircraft carriers converted for use as helicopter carriers. Modern designs support amphibious landing craft, with most designs including a well deck. Coming full circle, some amphibious assault ships also support V/STOL fixed-wing aircraft, now having a secondary role as aircraft carriers.

HNLMS Rotterdam is the lead ship in the Rotterdam-class landing platform dock of the Royal Netherlands Navy. The ship is named after the Dutch city of Rotterdam.

<span class="mw-page-title-main">Well dock</span>

In modern amphibious warfare usage, a well dock or well deck, officially termed a wet well during U.S. Navy instruction when the well deck is flooded for operations, is a hangar-like deck located at the waterline in the stern of some amphibious warfare ships. By taking on water the ship can lower its stern, flooding the well deck and allowing vessels such as boats and landing craft, amphibious vehicles, and recovered spacecraft crew capsules to dock within the ship.

USS <i>Mount Vernon</i> (LSD-39)

USS Mount Vernon (LSD-39) was an Anchorage-class dock landing ship of the United States Navy. She was the fifth ship of the U.S. Navy to bear the name. She was built in Massachusetts in 1972 and homeported in Southern California for 31 years until being decommissioned on 25 July 2003. Mount Vernon acted as the control ship for the cleanup of the Exxon Valdez oil spill. In 2005, she was intentionally destroyed off the coast of Hawaii as part of a training exercise. USS Mount Vernon also appeared in the Season 7 episode 19 of The Love Boat when they visited Hong Kong.
