An '''amphibious assault ship''' is a type of [[amphibious warfare ship]] employed to land and support ground forces on enemy territory by an [[Amphibious warfare|amphibious assault]].<ref>{{cite web|url= http://www.navy.mil/navydata/fact_display.asp?cid=4200&tid=400&ct=4 |title= Amphibious Assault Ships - LHA/LHD/LHA(R) |publisher= United States Navy |access-date= 2009-09-23| archive-url= https://web.archive.org/web/20090903155811/http://www.navy.mil/navydata/fact_display.asp?cid=4200&tid=400&ct=4| archive-date= 3 September 2009 | url-status= live}}</ref> The design evolved from [[aircraft carrier]]s converted for use as [[helicopter carrier]]s (and, as a result, are often mistaken for conventional fixed-wing aircraft carriers). Modern ships support amphibious [[landing craft]], with most designs including a [[Well dock|well deck]]. Coming full circle, some amphibious assault ships also support [[V/STOL]] fixed-wing aircraft, now having a secondary role as aircraft carriers.<ref>{{cite web |url=http://britains-smallwars.com/carriers/Theseus.html |title=HMS Theseus |publisher=Britains-smallwars.com |access-date=2013-09-03 |url-status=dead |archive-url=https://web.archive.org/web/20130806064331/http://www.britains-smallwars.com/carriers/Theseus.html |archive-date=2013-08-06 }}</ref><ref>{{cite web|url=http://www.naval-technology.com/projects/juan-carlos/ |title=Juan Carlos I Landing Helicopter Dock |publisher=Naval Technology |date=2011-06-15 |access-date=2013-09-03}}</ref>
 
The role of the amphibious assault ship is fundamentally different from that of a standard aircraft carrier: its aviation facilities have the primary role of hosting helicopters to support forces ashore rather than to support strike aircraft. However, some are capable of serving in the [[Command of the sea|sea-control]] role, embarking aircraft like [[Harrier Jumpjump Jetjet|Harrier]] or the new [[Lockheed_Martin_F-35_Lightning_II#F-35B|F-35B]] variant of the [[Lightning II]] fighters for [[combat air patrol]] and helicopters for [[anti-submarine warfare]] or operating as a safe base for large numbers of [[STOVL]] fighters conducting air support for an expeditionary unit ashore. Most of these ships can also carry or support landing craft, such as [[air-cushioned landing craft]] ([[hovercraft]]) or [[Landing Craft Utility|LCUs]].
 
The largest fleet of these types is operated by the [[United States Navy]], including the {{sclass|Wasp|amphibious assault ship|4}} dating back to 1989 and the very similar {{sclass|America|amphibious assault ship|0}} ships that entered service in 2014. Just as an aircraft carrier leads a [[carrier strike group]] in the US Navy, an amphibious assault ship leads an [[expeditionary strike group]]. Amphibious assault ships are also operated by the [[Royal Australian Navy]], the [[Brazilian Navy]], the Chinese [[People's Liberation Army Navy]], the [[Egyptian Navy]], the [[French Navy]], the [[Italian Navy]], the [[Republic of Korea Navy]] (South Korea) and the [[Spanish Navy]].

Due to their aircraft carrier heritage, all amphibious assault ships resemble aircraft carriers in design. The flight deck is used to operate attack and utility helicopters for landing troops and supplies and on some ship types also launch and recover fixed wing aircraft such as V/STOL [[Harrier Jumpjump Jetjet|Harrier "jump jet"s]] to provide air support to landing operations. STOL aircraft such as the [[North American Rockwell OV-10 Bronco]] were sometimes deployed on large-deck amphibious assault ships and were able to perform short take-offs and landings without needing catapults or arresting wires, although for safety and clearance reasons landings were most often not permitted.<ref>{{cite book |last=Polmar |first=Norman |title=The Naval Institute Guide To The Ships And Aircraft Of The U.S. Fleet |page=[https://archive.org/details/navalinstitutegu0018polm/page/392 392] |location=[[Annapolis, Maryland]] |publisher=[[United States Naval Institute#Publications and products|Naval Institute Press]] |year=2004 |isbn=1-59114-685-2 |url=https://archive.org/details/navalinstitutegu0018polm/page/392 |via=Archive.org }}</ref> [[Landing craft]] are also carried, either on deck-mounted [[davit]]s, or in an internal [[well dock]] (USN: "well deck").
