An '''amphibious transport dock''', also called a '''landing platform dock''' ('''LPD'''),<ref name="LPD RN">{{cite web|url=https://www.royalnavy.mod.uk/the-equipment/ships/assault/landing-platform-dock|title=Landing Platform Dock|author=Royal Navy|access-date=13 April 2019|archiveurl=https://web.archive.org/web/20190331194443/https://www.royalnavy.mod.uk/the-equipment/ships/assault/landing-platform-dock|archivedate=31 March 2019|url-status=bot: unknown}}</ref> is an [[amphibious warfare ship]], a warship that embarks, transports, and lands elements of a [[landing force]] for [[expeditionary warfare]] missions.<ref>{{cite news|title=Northrop wins contract add-on for 10th LPD-class amphibious transport dock ship|url=http://blog.gulflive.com/mississippi-press-news/2010/04/northrop_wins_contract_add-on_for_10th_lpd-class_amphibious_transport_dock_ship.html|newspaper=The Mississippi Press|date=30 April 2010}}</ref> 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 vehicle|amphibious transports]], [[amphibious cargo ship]]s, and the older [[dock landing ship]]s (LSD) by incorporating both a flight deck and a [[well deck]] that can be [[Ballast tank|ballasted]] and deballasted to support landing craft or [[amphibious vehicle]]s. 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.<ref name="gs">{{cite web |url=http://www.globalsecurity.org/military/world/amphibious-dock.htm|title=World Wide Landing Ship Dock/Landing Platform Dock|access-date=2012-05-17}}</ref> In the [[United States Navy]], the [[San Antonio-class amphibious transport dock|newer class of LPD]] has succeeded the older [[Ship class|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)-class amphibious warfare ship|LX(R)]] program to replace their LSDs.<ref>{{cite web|url=https://www.military.com/dodbuzz/2013/04/09/amos-replace-lsd-amphib-fleet-with-lpds|title=[USMC General] Amos: Replace LSD amphib fleet with LPDs|date=9 April 2013|publisher=military.com|access-date=23 March 2018}}</ref>
