Keel laying is the traditional start of ship construction. In the age of wooden ships, «keel laying» referred to the laying down of the piece of timber serving as the backbone of the ship or keel. Although modern manufacturing techniques allow fabrication of portions of a ship to begin many months earlier, the joining together of modules is considered the formal beginning of a ship.

The keel was authenticated to be «truly and fairly laid» by the ship’s sponsor, Meredith Berger, former Deputy Chief of Staff to the Secretary of the U.S. Navy who previously served as a senior policy advisor within the Department of Defense, the Environmental Protection Agency and the State of Florida.

«I’m very honored to have Ms. Berger here today to take part in this event», said Captain Brian Metcalf, LPD-17 class program manager for Program Executive Office (PEO) Ships. «Authentication of the ship’s keel is a major ship event and we’re looking forward to leveraging the experience and expertise of the Ingalls Shipbuilding team to achieve future production milestones».

San Antonio-class ships are designed to support embarking, transporting, and landing elements of over 800 Marines by landing craft, air cushion vehicles, helicopters, or MV-22 Osprey tilt-rotor aircraft. These ships support a variety of amphibious assault, special operations or expeditionary warfare missions, operating independently or as part of amphibious readiness groups, expeditionary strike groups, or joint task forces. The versatility of these ships also allows support of humanitarian efforts; USS New York (LPD-21), a sister ship, is currently underway from Mayport, Florida, offering support in the wake of Hurricane Irma.

LPD-28 is named in honor of the Florida city and will be the first U.S. Navy vessel to bear the name and will be the Navy’s 12th San Antonio-class amphibious transport dock ship. The future USS Fort Lauderdale (LPD-28) is planned for delivery in 2021. Eleven LPD-17 ships have been delivered, the most recent being USS Portland (LPD-27), which was delivered September 18, 2017. HII is also procuring long lead time material and advance procurement in support of LPD-29.

As one of the Defense Department’s largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, and boats and craft.

Contract Design Work

Huntington Ingalls Industries’ (HII) Ingalls Shipbuilding division has been selected to perform the majority of the contract design work for the U.S. Navy’s amphibious warfare ship replacement, known as LX(R). The Department of Defense made the announcement Thursday, on June 30, 2016, at the same time Ingalls was awarded a contract to build the next large-deck amphibious assault warship, LHA-8.

LX(R): The Future of Amphibious Warships

LX(R) will replace the Navy’s Harpers Ferry- and Whidbey Island-class dock landing ships and will use the same hull as the San Antonio (LPD-17) class. Ingalls has delivered 10 of the LPD-17 ships to the U.S. Navy, is currently building the 11th, USS Portland (LPD-27), and has received more than $300 million in advance procurement funding for the 12th, USS Fort Lauderdale (LPD-28).

«With a hot production line, skilled workers, a strong supplier base and deep experience building San Antonio-class LPD amphibious warships, Ingalls stands ready to close the gap between LPD-28 and LX(R), the next generation amphibious warships the Navy-Marine Corps team needs today», Ingalls Shipbuilding President Brian Cuccias said.

Navy needs new «docks»

It is not a secret of the Universe our World is changing. After the Russian-Georgian and Russian-Ukrainian war, NATO revised its understanding of Russia. Moscow made no secret of his ambition with regard to its neighbors. Thus, the United States understood the need to maintain amphibious fleet in a constant state of readiness to be able to move troops in Europe.

LPD Flight II
LPD Flight II, Huntington Ingalls Industries, Inc.

As said Sam LaGrone, the USNI Online Editor at the U.S. Naval Institute, Huntington Ingalls Industries (HII) has revised its plan to use the hull form of the San Antonio-class amphibious warship (http://navyarm.blogspot.ru/2014/11/san-antonio-class-lpd.html) as a candidate for the Navy’s next generation amphibious warship – LX(R).

HII’s new Flight IIA modifies the original LPD-17 design by removing some of the higher end capabilities of the San Antonio and creating a so-called amphibious truck to replace the existing class of aging Whidbey Island (http://navyarm.blogspot.ru/2014/11/whidbey-island-lsd.html) and Harpers Ferry (http://navyarm.blogspot.ru/ 2014/11/harpers-ferry-class-lsd.html) 16,000-ton landing ship docks (LSD).

The largest improvement in capability will be to the ship’s communication and aviation ability.

The current LSDs have a minimal command and control capability – the ability to communicate with other U.S. military forces and coordinate different types of aircraft and smaller vessel – and no native ability to host and maintain the aircraft of the trio of ships that make up the Navy’s Amphibious Ready Groups (ARGs).

The LX(R) will be much bigger than the ships it will be replacing – displacing about 7,000 more than the current LSDs at 23,470 tons, HII officials told USNI News.

Instead of the four Colt-Pielstick diesel engines, HII’s model reduces the prime mover count to two unspecified main propulsion diesel engines (MPDE).

The Mark-46 30mm gun weapon system is replaced with a Mark-38 Mod 2 remote controlled 25mm chain gun providing offensive and defensive ability.

The AN/SPS-48E air search radar is replaced with a TRS-3D, which is currently outfitted on the National Security Cutter providing a more suitable sensor for its mission.

The Flight IIA retains about half of the medical spaces on the LPD. Company officials also said the current iteration would feature two spots for the Navy’s LCAC hovercraft or one utility landing craft (LCU) – which is in line with the Navy’s current thinking for requirements for the LX(R). Other changes include reducing the troop capacity from 800 to 500 with a crew of about 400 sailors.

Though HII is original designers and builders of the LPD-17 ships, they are not guaranteed the design and construction contract for the new LX(R) ship class. General Dynamics NASSCO in San Diego, California has also helped the Navy in its current push to lower the cost at the start of the acquisition process and is considered likely to bid on the final work.

The Navy’s frontend analysis of alternatives process for LX(R) has been described as, «the best ship design conversation we’ve had in a long time inside the government», NAVSEA chief Vice Adm. William Hilarides said in May.

HII officials didn’t announce a cost estimate for their version, but according to past information from the Navy a San Antonio LX(R) could cost about $1.64 billion for the lead ship with follow-ons costing about $1.4 billion for a total of 11 ships.
