42-738: The San Antonio class is a class of amphibious transport docks , also called a "landing platform, dock" (LPD), used by the United States Navy . These warships replace the Austin -class LPDs (including Cleveland and Trenton sub-classes), as well as the Newport -class tank landing ships , the Anchorage -class dock landing ships, and the Charleston -class amphibious cargo ships that have already been retired. Twelve ships of

84-701: A 12th ship as a bridge to building the LX(R) (formerly LSD(X)) on the same hull, but the USN has indicated that the requirements of the LX(R) have not yet been settled and that the LPD-17 hull might be too large for such a mission. However, Commandant James F. Amos had also endorsed dropping LSD in favor of continued LPD production. In October 2014, Secretary of the Navy Ray Mabus signed an internal memo recommending that

126-496: A 93-foot-high octagonal structure 35 feet in diameter, is constructed of a multi-layer frequency-selective composite material. It is designed to permit the ship's own sensor frequencies with very low loss while reflecting other frequencies. The tapered octagonal shape of the AEM/S is designed to reduce the radar cross section, and enclosing the antennas provides improved performance and greatly reduces maintenance costs. The composite mast

168-410: A class often have names linked by a common factor: e.g. Trafalgar -class submarines ' names all begin with T ( Turbulent , Tireless , Torbay ); and Ticonderoga -class cruisers are named after American battles ( Yorktown , Bunker Hill , Gettysburg , Anzio ). Ships of the same class may be referred to as sister ships . The name of a naval ship class is most commonly the name of

210-708: A second flight of 13 planned LPD Flight II ships, for a total of 26 in the LPD 17 class; LPD 30, Harrisburg , is the first Flight II ship. The San Antonio class was designed to provide the Navy and U.S. Marine Corps with modern, sea-based platforms that are networked, survivable, and built to operate with 21st century transformational platforms, such as the MV-22 Osprey , the (since canceled) Expeditionary Fighting Vehicle (EFV), air-cushioned landing craft (LCACs), and future means by which Marines are delivered ashore. The ship

252-458: A single letter suffix. After the reunification of Germany the German Navy ( Deutsche Marine ) kept the system. Informally, classes are also traditionally named after their lead ships. The Indonesian Navy has a traditional naming system for its ships. In addition, the ship's type and missions can be identified by the first number on the ship's three-digit hull number , which is placed on

294-589: A twelfth San Antonio -class ship (LPD-28). In early 2014, Huntington Ingalls Industries (HII) displayed its Flight IIA version of the LPD-17 hull for the Navy's LX(R) amphibious ship. The design is further modified by removing some of the higher-end capabilities of the San Antonio class to create an "amphibious truck" to replace the Whidbey Island and Harpers Ferry landing ship docks . The Flight IIA has improved command and control (C2) features over

336-516: Is more than 45 percent larger than the Austin class, displacing more than 25,000 tons at full load. It carries fewer troops, but has twice as much space for vehicles, landing craft, and aircraft. The ships are also suited to act as recovery ships for spacecraft, with a floodable well deck at the back of the vessel into which a capsule can float; Portland was the recovery ship for the Orion capsule of

378-462: The Artemis 1 uncrewed Moon-orbiting mission on 11 December 2022. The project embraced a "Design for Ownership" philosophy; a concurrent engineering approach that injects operator, maintainer, and trainer input into the design development process. The goal was to ensure that operational realities are considered throughout the total ship design, integration, construction, test and life cycle support of

420-526: The Confederate States Navy . Generally accepted by military historians and widely used in the more recent books, webpages and papers on the subject matter (most notably the releases of Osprey Publishing ), these latter-day classifications are sometimes considered "semi-official" (although they are not). Contemporary records, such as the " Official Records of the Union and Confederate Navies in

462-433: The San Antonio class were originally proposed, their original target price was US$ 890 million; as built, their average cost is $ 1.6 billion. Defense Authorization for Fiscal Year 2015 included partial funding for the twelfth San Antonio -class ship. As of December 2022 eleven warships of this class were in service with the U.S. Navy, with an additional three ships under construction. The Navy decided in 2018 to produce

504-495: The United States Navy . The ship is the first ship of the United States Navy to be named for Fort Lauderdale, Florida . Fort Lauderdale features design improvements developed in connection with the Navy's development of a next-generation dock landing ship , known as the LX(R) -class amphibious warfare ship . The LX(R) is intended to replace current Whidbey Island -class and Harpers Ferry -class dock landing ships. In 2014,

546-474: The lead ship , the first ship commissioned or built of its design. However, other systems can be used without confusion or conflict. A descriptive name may be used; for example it was decided to group destroyers made to the same design as HMS Tomahawk , all named after weapons, as the Weapon rather than Tomahawk class. In European navies, a class is named after the first ship commissioned regardless of when it

588-523: The Flight I ships. The mission provided by Flight II ships will include airport, seaport, and hospital operations and incorporate modifications to the ships’ well decks. As of March 2023, the US Navy is proposing to temporarily halt acquiring additional San Antonio class ships beyond LPD-32. This move would be part of a "strategic pause," according to Navy Secretary Carlos Del Toro , that would allow

630-461: The LSDs, half the medical spaces of the LPD-17, a smaller hangar, no composite masts, two unspecified main propulsion diesel engines (MPDE), two spots for LCACs or one LCU, a reduced troop capacity (500), and a crew of about 400 sailors. In January 2015, the Navy and Marine Corps decided to go with the modified LPD-17 hull for the LX(R) program. Chief of Naval Operations Greenert considered using some of

672-409: The LX(R) warship be based on the existing San Antonio -class design. The LPD-17 design was selected over a foreign variant, and an entirely new design to meet required capability, capacity, and cost parameters. Official selection of basing the LX(R) off the LPD-17 design still has to come with Milestone A approval. The National Defense Authorization Act for Fiscal Year 2015 included partial funding for

714-417: The Navy commenced design of LX(R) based on a modified San Antonio -class design. Because this design work is in progress, the Navy has created design innovations and cost-reduction strategies around the San Antonio -class design, and the Navy believes that it can apply these innovations and strategies to Fort Lauderdale , allowing her to be built at reduced cost. The main design features intended to reduce

756-508: The U.S. Navy, such that it will be modeled in wargame scenarios in 2016 and 2017. It could accommodate up to 288 Mk41 VLS missile tubes and a radar with 1000 times the sensitivity of the SPY-1D radar of the Burke destroyers. On 2 August 2018, the U.S. Navy and Huntington Ingalls signed a contract for long lead items for LPD-30, the first of the 13-ship more affordable Flight II class. The contract

798-586: The War of the Rebellion " (Series 2, Volume 1, Part 1), show that the modern nomenclature was not in use at the time. The unofficial retro-applying of ship classes can occasionally lead to confusion. For example, while American works consistently adhere to the City - and Columbia -class monikers, works of British origin refer to the same classes as Cairo class and Tennessee class respectively, in compliance with

840-582: The accepted European convention, some classes have been named after a common theme in the included ships' names, e.g., Tribal-class destroyers , and some classes were implemented as an organizational tool, making traditional methods of naming inefficient. For instance, the Amphion class is also known as the A class. Most destroyer classes were known by the initial letter used in naming the vessels, e.g., V and W-class destroyers . Classification by letter also helped to conflate similar smaller classes of ships as in

882-525: The case of the A-class destroyers of 1913 whose names spread across the alphabet. Since the end of the Second World War , Royal Navy ship classes have also been known by their type number (e.g. Type 45 destroyer .) For the United States Navy , the first ship in a class to be authorized by Congress is the designated class leader and gives the name to the class, regardless of the order in which

924-445: The class has extensive communications, command, control, and intelligence systems to support current and projected expeditionary warfare missions of the 21st century. The class is fitted with the integrated Ship Self-Defense System (SSDS). The system fuses the radars and other sensors and controls the weapons systems for an automated fast reaction capability against air threats. The Advanced Enclosed Mast/Sensors (AEM/S) System mast,

966-434: The class, USS San Antonio , had several deficiencies which rendered it "not operationally effective, suitable, or survivable in a hostile environment". In April 2015, the USN proposed adding a 12th ship to the class, which will be built at Ingalls in exchange for a destroyer to be named later. On 4 December 2015, the 12th ship was ordered. U.S. senator Kay Hagan has asked if the LPD-17 construction line should be extended to

1008-404: The combat system. Following the extended problems and incidents experienced by USS  San Antonio , the U.S. Department of Defense's Director, Operational Test and Evaluation (DOT&E), stated in 2010 that the ships are "capable of operating 'in a benign environment', but not effective, suitable and not survivable in a combat situation". The DOT&E found in 2011 that the first ship of

1050-554: The cost of Fort Lauderdale compared to the San Antonio -class on which she is based are simplified bow works, replacement of the forward and aft composite masts with steel masts, removal of structures from the boat valley, and a stern gate which is open at the top. This will make Fort Lauderdale a "transitional ship" between the current San Antonio -class design and future LX(R) vessels. Fort Lauderdale incorporates high temperature superconductor -based mine protection degaussing system built by American Superconductor to reduce

1092-413: The course of building a class of ships, design changes might be implemented. In such a case, the ships of different design might not be considered of the same class; each variation would either be its own class, or a subclass of the original class (see County-class cruiser for an example). If ships are built of a class whose production had been discontinued, a similar distinction might be made. Ships in

1134-673: The current convention to historical naval vessels sharing similarities, such as those of the American Civil War , where the Union Navy built several vessels in series, which can be termed "classes" as presently understood. Common examples include the Passaic -class monitor and the City-class ironclad , among many others, for the Union side, and Columbia class or Richmond class , for those ironclads in service with

1176-565: The extra space in the San Antonio class to mount modular equipment in the same fashion as the littoral combat ships . As part of their bid to offer "Flight II" LPD-17s for the dock landing ship replacement contract, HII has suggested fitting out the ships to carry the Aegis Ballistic Missile Defense System . Although there is no formal requirement for the BMD variant, HII report unofficial support for it within

1218-480: The first USN ships designed to accommodate sailors and Marines of both sexes as part of the crew and embarked troops. By mid-2016, the Navy and Marine Corps were studying installing a vertical launch system (VLS) into San Antonio -class ships so they could field larger offensive missiles. The original ship concept included two 8-cell Mk 41 VLS in the bow, which is being reexamined to add Tomahawk cruise missiles to support Marines ashore with little modification to

1260-508: The force to better examine what they need to get out of the ships and how many they ultimately need. Under this plan, LPD-32 would be purchased in the 2022–2023 fiscal year. In August 2024, Congress authorized the Navy to begin a multi-year procurement of three ships. The multi-year procurement deal, spanning FY25 to FY29, will save an estimated $ 901M compared to individual ship buys. These three ships are excluded from this page's "on order" counts until formally executed. Ship class In

1302-788: The front bows and the back of the stern. The naming convention is: Russian (and Soviet ) ship classes are formally named by the numbered project that designed them. That project sometimes, but not always, had a metaphorical name, and almost always had a NATO reporting name . In addition, the ships of the class would have a number prefixed by a letter indicating the role of that type of vessel. For example, Project 641 had no name, though NATO referred to its members as Foxtrot-class submarines . The ship classification does not completely correspond common designation, particularly for destroyers, frigates and corvettes. Russia has its own classification system for these ships: The British Royal Navy (RN) has used several methods of naming classes. In addition to

1344-482: The magnetic signature of the ship. On 9 March 2016, the ship was given the name Fort Lauderdale , and the contract to build her was awarded to HII's Ingalls Shipyard on 19 December 2016. Fort Lauderdale 's keel was laid down on 13 October 2017, at Ingalls Shipyard in Pascagoula, Mississippi. She was launched on 28 March 2020, and her acceptance trials were completed on 31 January 2022. The ship

1386-661: The modern Royal Navy naming conventions. By the time the United States entered World War II, the current naming convention was in place, though it remains unclear as to exactly how and when the practice originated. Merchant ships are almost always classed by a classification society . These vessels are said to be in class when their hull, structures, machinery, and equipment conform to International Maritime Organization and MARPOL standards. Vessels out of class may be uninsurable and/or not permitted to sail by other agencies. A vessel's class may include endorsements for

1428-545: The name of the ship was announced as USS  Harrisburg for Harrisburg, Pennsylvania , the state's capital . On 3 April 2020, Huntington Ingalls announced that it was awarded a $ 1.5 billion contract modification for the construction of USS  Pittsburgh , named for Pittsburgh, Pennsylvania . The Flight II ships are intended to provide the mission currently provided by the Whidbey Island-class dock landing ships and incorporate more than 200 changes over

1470-474: The new ships and their systems. This process was intended to improve combat readiness, enhance quality of life, and reduce Total Ownership Costs, and resulted in numerous changes during the project. The San Antonio class has significant survivability features and computer technology. In addition to Rolling Airframe Missile (RAM) protection from air threats, the class was designed to minimize radar signature. Techniques that reduce radar cross-section (RCS) make

1512-411: The ships more difficult to locate and target. Enhanced survivability features include improved nuclear blast and fragmentation protection and a shock-hardened structure. The fiber-optic shipboard-wide area network (SWAN) connects onboard-integrated systems. The network will allow "plug in and fight" configuration, updating and replacing hardware more easily when newer technology becomes available. Moreover,

1554-459: The ships of that class are laid down, launched or commissioned. Due to numbering conventions, the lead ship often has the lowest hull number of its class. (During World War II , the award of construction contracts was not always congruent with completion, so several ships had higher hull numbers than later ships.) Before the 1920s, naval vessels were classified according to shared characteristics. However, naval historians and scholars retro-apply

1596-460: The type of cargo such as "oil carrier", "bulk carrier", "mixed carrier" etc. It may also include class notations denoting special abilities of the vessel. Examples of this include an ice class , fire fighting capability, oil recovery capability, automated machinery space capability, or other special ability. USS Fort Lauderdale USS Fort Lauderdale (LPD-28) is the twelfth Flight I San Antonio -class amphibious transport dock ship of

1638-545: Was commissioned during a ceremony in her namesake city of Fort Lauderdale, Florida , on 30 July 2022. She arrived at her homeport in Norfolk, Virginia on 4 August 2022. In June 2024, Fort Lauderdale was part of Maryland Fleet Week at Baltimore Inner Harbor . [REDACTED]   This article includes information collected from the Naval Vessel Register , which, as a U.S. government publication,

1680-586: Was for US$ 165.5M. The cost goal is for US$ 1.64B for the first ship, and $ 1.4B for subsequent ships. LPD-30 will be fitted with a Raytheon AN/SPY-6 Enterprise Air Surveillance Radar , an upgrade over the AN/SPS-48 currently in LPD-17s. Huntington Ingalls will build the new flight exclusively. On 26 March 2019, Huntington Ingalls announced the award of a US$ 1.47 billion, fixed-price incentive contract for LPD 30 (14th ship and first of Flight II). On 10 October 2019,

1722-606: Was ordered or laid down. In some cases this has resulted in different class names being used in European and U.S. references; for example, European sources record the Colorado -class battleships of the United States Navy as the " Maryland class", as USS  Maryland was commissioned before USS  Colorado . The West German Navy ( Bundesmarine ) used a three-digit type number for every class in service or in advanced project state. Modified versions were identified by

1764-501: Was replaced by a conventional mast starting from USS Fort Lauderdale as a transition to the LX(R)-class amphibious warfare ship design. The San Antonio -class also incorporates the latest quality of life standards for the embarked Marines and sailors, including sit-up berths, a ship services mall, a learning resource center, and a fitness center. Medical facilities include two operating rooms and 124 beds. Additionally, they are
