상륙함으로부터 해안으로 물자등을 운반하는 다목적상륙용 주정 LCU(Landing Craft Utility)의 여러모습

Landing Craft Utility (LCU) LCU 1610, 1627 and 1646 Class
The LCU-1600 transports wheeled and tracked equipment and general cargo from ship to shore, shore to shore, and in retrograde operations. RORO missions are accomplished using the vessel’s bow and stern ramps. It is valuable in LOTS operations and intratheater transport using harbor and IWW routes. The LCU-1600 is not capable of self-deployment over open oceans. It is deployed aboard vessels such as HLPSs, barges, and FLOFLO ships. It can also be loaded on Navy LSTs, LSDs, or commercial bulk carriers.
The 189 ton LCU are designed to carry 3 M-60 tanks, as many as 450 combat equipped troops or a variety of other support equipment such as surf cranes, bulldozers, trucks or artilleries. An LCU has a complement of a ten man crew consisting of a Radioman, Engineman, Electricians, Mess Management Specialist, Quartermasters and Boatswainmate, under the command of a Chief or First Class Craftmaster. The Craftmaster is wholly responsible for this craft and crew.

LCU 2000
The LCU 2000 moves containers/general/ vehicular cargo. This includes missions in LOTS operations in remote areas with austere shore facilities or unimproved beaches. The LCU 2000 is also suitable for the intratheater movement of cargo and unit equipment along coastlines or inland waterways. It is used for unit deployment and relocation.
It has a bow ramp for Roll-on/Roll-off cargo, and a bow thruster to assist in beaching and beach extraction. Because of its shallow draft, the LCU 2000 can carry cargo from deep draft ships to shore ports or areas too shallow for larger ships. The LCU-2000 provides worldwide transport of combat vehicles and sustainment cargo, as well as intratheater movement and can execute cargo operations along coastal MSRs. It is capable of receiving cargo from a ship anchored in the stream and transporting that cargo to shore for discharge over the bow ramp. Because of its shallow draft, the LCU can carry cargo from deep drafted ships to shore ports or areas too shallow for larger ships.
The LCU 2000 transports rolling and tracked vehicles, containers, and outsized and general cargo from ships offshore to shore (LOTS), as well as to areas that cannot be reached by oceangoing vessels (coastal, harbor, and IWWs). It can be self-deployed or transported aboard a FLOFLO vessel. It is classed by the ABS for full ocean service and one-man engine room operations and is built to USCG standards. The LCU 2000 succeeds the 1646 Class LCU and replaces the 1466 Class in both the Army’s Active and Reserve inventories. The Army had 35 LCU 2000s
