My Review and Build of Orange Hobby's 1/350 scale KIT #N03-130-1400,
USS Harpers Ferry LSD-49 Landing Ship Dock (LSD)
Harper's Ferry Class Landing Ship dock (LSD)
The Harper's Ferry Class Landing Ship Dock are a class of LSD's that followed the Whidbey Island Class of eight vessels. They used the same hull, but some significant differences were made in the Harper's Ferry to better suite the US Navy needs and to give the US Navy more flexibility in the formation and use of its Amphibious Ready Groups, which are the essential Amphibious assault portion of a Marine Expiditionary Unit (MEU).
Normally, an ARG consists of:
1 x LHD or LHA Large flatdeck Amphibious Assault vessel capable of carrying up to 2,000 Marines and all of their equipment, as well as the aircraft to jelp land and support them
1 x LPD, a large Amphibious vessel with a smaller ddeck, but still capable of carryoing up tpo 800-900 marines and their equipment and the aircraft to help land them.
1 x LSD, a large ladning ship dock capable of carryoing 500 or more Marines and all of their equipment and landing spots for the aircraft to help land them.
Note, outside of ceertain LHA vessels, all of these vessels also contain large well d3ecks to accomodate LAnding Craft Air Cushions (LCAC), MAnding Craft utility (LCU), and Amphibious YTank and personnel carriers to get the troops to shore in addition to having them flown there in air assault aboard various types of helicopters and/or MV-22 Osprey vertical landing aircraft.
The LHD/LHA and LPDs aslo have spacious hangers for their aircraft.
The LSDs do not have hangars for the aircraft used to transport their troops.
The eight Whidbey Island LSDs which preceded the Harper's Ferry class could each carry up to four LCAC, which meant their well decks were extrremely long. This is good for moving a lot of troops at once, but also decreased the amouint of storage room within the ship itself for verhicles, equipment, and armor.it was felt that a class of LSDs should be built tht could carry more of the equiment for the MArines, and so the HArper's Ferry Class was built to give this fllexibility to the overall ARG.
Haprers Ferry Class LSDs can only accomodate twp LCACs, but have a lot more storage decks and space for equipment. This increased the displacement of the Harper's Ferry class. Where as the Whidbey ISland class looks very much like the Harper's Ferry class, each of those vessels displace 16,100 tons, while the Harper's Ferry displaces 19,600 tons full load. 3,500 tons of structure and additional equipment for the Marines.
This makes these vessels very valuable to the US Navy and US MArines, and gives the US military forces much more flexibility in their planning of amphibious operations.
The four vessels that were built that comprise the Haprer's Ferry Class include:
USS Harpers Ferry, LSD-49, built by Avondale Shipyard, Commissioned on January 7, 1995, and based at Naval Base San Diego (CA)
USS Carter Hall, LSD-50, built by Avondale Shipyard, commissioned September 30, 1995, and based at Naval Amphibious Base Little Creek (VA)
USS Oak Hill, LSD-51, built by Avondale Shipyard , commissioned June 8, 1996, Nnd based at Naval Amphibious Base Little Creek (VA)
USS Pearl, Harbor LSD-52, built by Avondale Shipyard, commissioned May 30, 1998, and based at Naval Base San Diego (CA)
These vessels are expected to serve for 40 years, and will begin decommissioning in the mid-2030s.
The replacement class for the twelve LSDs (Both the Whidbey Island Class and the Harper's Ferry class) is already in final design since the vessels in the Whidbey ISland Classs will begin decommissioning in
the mid-2020s. The new LSD will be built on the same hull as the San Antonio Class LPD, but with the features of the LSD.

The Harper's Ferry LSD vessels are an essential part of the US Navy and US Marine policy and methodology for being able to project US military power when necessary and to assault shorelines according to the direction of the US Command Authority, meaning the president of the United States.
