With the launch of the amphibious transport ship {{Ship|HNLMS|Rotterdam|L800|6}} in 1998 there was a need for LCUs. The Dutch LCUs are similar to the British LCU Mk.10 with the bridge being set to one side allowing for a roll-on roll-off design. Until 2005 the [[Netherlands Marine Corps]] used the [[:(NL)LCU#(NL)LCU type Mk.I|LCU Mark I (NL)]].

In 2005 and 2006 the five vessels were modernized to the [[:(NL)LCU#(NL)LCU type Mk.II|type Mark II]]. The vessels have been stretched by 9 meters to decrease their draft, which increased their load carrying capacity by 20 tons and allows them to come closer to shore. In addition they were fitted with a strengthened bow ramp, and they can now accommodate the [[Royal Netherlands Army]] [[Leopard 2]] A6 main battle tank.
Because of the lengthening of the Mark II, the ''Rotterdam'' can take two LCUs (plus three [[(NL)LCVP|LCVPs]]) in its dock. The dock of ''Rotterdam''{{'}}s sister ship, [[HNLMS Johan de Witt (L801)|HNLMS ''Johan de Witt'']], has the capacity to transport two LCUs, but carries four LCVPs in davits.

===LCU Mk.9===
The LCU Mk.9 was built for use on the LPDs {{HMS|Fearless|L10|2}} and {{HMS|Intrepid|L11|2}} where they were operated from the dock in the rear of the ships.<ref name="RNH106">The Royal Navy Handbook, page 106</ref> Each ship carried four LCUs and four davit mounted LCVPs. The Mk.9 was to see many changes and upgrades during its service including a move from propeller to jet in many cases. The Mk.9 was capable of traveling as an ocean-going vessel and a number would be converted into a version, affectionately known as the "Black Pig", for use in [[Norway]]. The crew had full living quarters aboard with galley and heads. In the [[Falklands War]] during the [[Bluff Cove Air Attacks]] LCU F4 from {{HMS|Fearless|L10|2}} was bombed and sunk in Choiseul Sound by an [[Argentine Air Force]] A-4B [[Douglas A-4 Skyhawk|Skyhawk]] of Grupo 5.<ref name="Part 52. BRITISH SHIPS LOST & DAMAGED">{{cite web|url=http://www.naval-history.net/F62-Falklands-British_ships_lost.htm|title=British Ships sunk and damaged - Falklands War 1982|website=www.naval-history.net}}</ref> The Mk.9, like the LPDs, served longer than ever anticipated, providing the backbone of Britain's amphibious assault capabilities.

Three Mk.9s, [[pennant number]]s 701, 705, and 709, remained in service by 2012.<ref name="RNH106"/><ref name="IISS">"The Military Balance 2012", [[International Institute for Strategic Studies]], pp. 170–171</ref> However, by 2014, they had all been withdrawn from service.<ref name="Steve Bush 2014">{{cite book|last=Bush|first=Steve|title=British Warships and Auxiliaries|year=2014|publisher=Maritime Books|pages=35–39 |isbn=978-1904459552}}</ref>

===LCU Mk.10===
The LCU Mk.10 class vessels are operated by the [[Royal Marines]]. They are intended for use on board the assault ships {{HMS|Albion|L14|2}} and {{HMS|Bulwark|L15|2}} and can also be used by the [[Bay class landing ship]]s. Deliveries of the class started from 1998 and the fleet currently consists of nine vessels. Both Albion and Bulwark are capable of carrying four LCUs each. These vessels are capable of operating independently for up to 14 days with a range of 600 nautical miles. They are capable of operating worldwide, from Arctic operating areas to tropical operating areas. The Mk.10 differs greatly from the Mk.9 with the bridge being set to the side allowing for a [[roll-on roll-off]] design. This greatly increases efficiency over the old Mk.9 as loading of the rear LCUs can take place without the LCUs being launched, the LPD having to dock down to do so, to change over and load up, which was a problem prior to the Falklands landings. The LCU Mk.10 has a 7-man crew and can carry up to 120 Marines or alternatively 1 battle tank or 4 lorries. British assault ships also carry smaller [[LCVP (United Kingdom)|LCVP]]s on davits to transport troops and light vehicles.

Ten Mk.10s, pennant numbers 1001 to 1010, were in service as of 2012.<ref name="IISS"/> In 2023 it was reported that 9 of the craft remained in service.<ref>{{cite web |url=https://www.royalnavy.mod.uk/-/media/royal-navy-responsive/images/navynews/archivepdfs/2020s/2023/navy-news-february-2023-issue-823.pdf?rev=d6ed03242b4e475684f2ea061fb2d2d3 |title=Royal Navy Fleet Poster p.21 |date=February 2023 |website=Navy News |access-date=13 June 2023}}</ref>

==United States==
The United States Navy built 1,394 [[Landing Craft Tank|Landing Craft Tank (LCT)]] in World War II. Those that were still in use in 1949 were redesignated as Landing Craft Utility (LCU).

Seventy old LCUs (likely ex-LCTs) were retired from amphibious duties and reclassified as [[List of yard and district craft of the United States Navy#Harbor utility craft (YFU)|Harbor utility craft (YFU)]].

The LCU 1466, 1610 and 1627 class vessels are operated by the [[United States Navy]] at support commands.<ref name=Friedman_p390>Friedman, 2002, p 390</ref><ref name=NavSource>{{cite web|title=Landing Craft Utility (LCU)|url=http://www.navsource.net/archives/10/18/18idx.htm|website=NavSource Naval History|access-date=19 July 2015}}</ref> They are a self-sustaining craft complete with living accommodations and mess facilities for a crew of thirteen.<ref name=JNI20130128 /> Each LCU is assigned a non-commissioned-officer-in-charge (Craft Master) who is either a [[Chief Petty Officer|chief petty officer]] or [[Petty Officer First Class|petty officer first class]] in the boatswain's mate, quartermaster or operations specialist rating. These vessels have [[Drawbridge|bow ramps]] for onload/offload and can be linked bow to [[Linkspan|stern gate]] to create a temporary pier-like structure. Its welded steel [[Hull (watercraft)|hull]] provides high durability with deck loads of 3,900&nbsp;kg/m<sup>2</sup> (800 pounds per square foot). Arrangement of machinery and equipment has taken into account built-in redundancy in the event of battle damage. 

The craft features two engine rooms separated by a watertight [[Bulkhead (partition)|bulkhead]] to permit limited operation in the event that one engine room is disabled. An anchor system is installed on the starboard side aft to assist in retracting from the beach. These vessels are normally transported to their areas of operation onboard larger amphibious vessels such as [[Dock landing ship|LSDs]], [[Landing Helicopter Dock|LHD]]s and [[Landing Helicopter Assault|LHA]]s. 

Introduction of the larger LCU-1610 class resulted in the US Navy constructing the {{sclass|Anchorage|dock landing ship|4}} of Landing Ships, Dock (LSD).<ref>Friedman, 2002, pp 331-334</ref>

LCU-1618 was converted to support the testing of [[Remotely operated underwater vehicle]]s and [[Autonomous underwater vehicle]]s and was given the name USS ''Orca'' (IX-508).<ref name=NavSource_1618>{{cite web|title=NavSource Online: Amphibious Photo Archive |url=http://www.navsource.net/archives/10/18/181618.htm |website=NavSource Naval History|access-date=12 June 2023}}</ref>

===LCU 1700===

The LCU 1700-class boats are destined to replace the existing LCU 1610-class of amphibious landing craft on a one-to-one basis. The LCU-1700 is 139 feet long, can reach speeds of 11 knots, has a range of 1,200 nautical miles at 8 knots, and has accommodations for a mixed gender crew of 14. It can carry two M1A1 tanks, or 350 combat troops, or 170 short tons of cargo.<ref>{{cite web | url=https://www.navsea.navy.mil/Home/Team-Ships/PEO-Ships/LCU/ | title=LCU }}</ref> 

The contract announcement noted that the LCU 1700s will recapitalize the LCU fleet as a similarly rugged steel craft (to the LCU 1610) with a design life of 30 years.<ref>{{cite web|url=https://www.defensedaily.com/navy-awards-swiftships-50-million-lcus/navy-usmc/|title=Navy awards|date=3 April 2020 |publisher=Defensedaily|access-date=26 April 2022}}</ref> The similarities of these two classes of ships will help the U.S. Navy to improve efficiency and reduce cost of the training programs, operations and overall ownership cost. The craft will enter, exit and be transported in well decks of current and programmed U.S. Navy amphibious warfare ships, for design purposes defined by the dimensions of LHD, LPD, LSD and LHA classes without ship alterations, while transporting loads up to 11 feet high above the craft’s vehicle deck.<ref>{{cite web|url=https://militaryleak.com/2021/05/09/us-navy-awards-swiftships-59-million-in-landing-craft-utility-1700-class-1707-1711/|title=US Navy awards Swiftships|date=9 May 2021 |publisher=Militaryleak|access-date=25 April 2022}}</ref> The contract was awarded to [[Swiftships]] in 2018 to design and build the prototype and up to 32 vessels. Work was to be performed in [[Morgan City, Louisiana]], and was expected to be completed by November 2023.<ref>{{cite web|url=https://defbrief.com/2020/04/03/us-navy-orders-further-lcu-1700-landing-craft-utility-vessels/|title=US Navy orders|date=3 April 2020 |publisher=debrief|access-date=25 April 2022}}</ref><ref>{{cite news|url=https://www.navalnews.com/naval-news/2019/02/swiftships-to-deliver-further-two-lcu-1700-units-for-us-navy-amphibious-forces/|title=Swiftships to deliver|newspaper=Naval News |date=6 February 2019 |publisher=NavalNews|access-date=25 April 2022}}</ref> By 2020, the Navy had ordered six vessels from Swiftships at a total cost of about $95 million.<ref name="stop work"/>  In January 2024, following delays in the scheduled delivery of the first three vessels and continued design changes, the Navy ordered Swiftships to stop work on construction; the contract was terminated entirely the following month.<ref name="stop work">{{cite web | url=https://www.defensenews.com/naval/2024/02/23/us-navy-orders-swiftships-to-stop-work-on-its-landing-craft-program/ | title=US Navy orders Swiftships to stop work on its landing craft program }}</ref>
