LPD 17

The design of the San Antonio Amphibious Assault Ships was jointly developed by Navy, Marine Corps and industry stakeholders to provide superior performance over a broad range of operational requirements. LPD 17 provides the Navy and Marine Corps with modern, sea based platforms for execution of Expeditionary Warfare Missions. Each ship’s survivability features allow the crew to confidently sail into harm’s way and extend their reach with the compliment of air cushioned landing craft, helicopters or tilt rotor aircraft.

LPD 29 TRANSLATION & LAUNCH

The U.S. Navy amphibious transport dock Richard M. McCool Jr. (LPD 29) was launched at Ingalls Shipbuilding in Pascagoula, Mississippi, on Wednesday, January 5, 2022.

lpd FACTS

The San Antonio-class is a major part of the Navy’s 21st century amphibious assault force. The 684-foot-long, 105-foot-wide ships are used to embark and land Marines, their equipment and supplies ashore via air cushion or conventional landing craft and amphibious assault vehicles, augmented by helicopters or vertical takeoff and landing aircraft such as the MV-22 Osprey. The ships support a Marine Air Ground Task Force across the spectrum of operations, conducting amphibious and expeditionary missions of sea control and power projection to humanitarian assistance and disaster relief missions throughout the first half of the 21st century.

An LPD amphibious transport dock is equipped with:

  • Two 30 mm Bushmaster II cannons for surface defense
  • Two Rolling Airframe Missile (RAM) launchers for air defense
  • Four CH-46 Sea Knight helicopters
  • Two LCACs, one LCU and 14 AAVs
  • Four diesel engines that can reach a maximum speed of more than 22 knots.

DESIGN & CONSTRUCTION

Ingalls Shipbuilding is the sole provider of the San Antonio (LPD 17) class of amphibious transport dock ships for the U.S. Navy. The versatile 684-foot-long ships are designed with the goal of meeting the Navy and Marine Corps needs, embracing a “Design for Ownership” philosophy to interact with the fleet’s operating forces.

The unique design-engineering approach injected fleet input into the development process before construction began and shaped every element of the ships’ systems and spaces to meet future requirements.

Each LPD consists of 210 units built utilizing modular construction techniques. Each unit is extensively pre-outfitted with piping, electrical, machinery and ventilation systems along with many pieces of equipment prior to launch.

PROVIDING NEXT GENERATION CAPABILITY TODAY: ACCELERATING LPD FLIGHT II WILL ENHANCE NAVAL CAPACITY AND LETHALITY

LPD 30, the first LPD Flight II is a flexible, survivable and affordable warship that will fulfill the Navy and Marine Corps’ requirements. Using the LPD 17’s proven hull, this LPD derivative is highly adaptable and will be used across the range of military operations, from major combat operations to humanitarian assistance and disaster relief through use of its well deck, flight deck, hospital facilities, and self-defense features.

Accelerating this next generation warship will help provide distributed maritime capability, leverages a hot production line, and is important and continued investment in a supplier base of 400 companies in 30 states. In addition to the affordability gained by using the LPD hull for Flight II, further savings can be achieved through a multi year procurement or a block buy acquisition strategy similar to the Virginia-class submarine and the Arleigh Burke destroyer programs.

The LPD Flight II will meet the requirements for the next generation amphibious warship the Navy-Marine Corps Team needs now.

WHY LPD FLIGHT II?

LPD Flight II is the right choice for the next generation amphibious ship to replace the Whidbey Island (LSD 41) and Harpers Ferry (LSD 49) classes of dock landing ships. The LPD Flight II is substantially more capable than both ship classes at an affordable cost. The design, a derivative of LPD 29, is stable and ready for serial construction of 13 LPD Flight II ships beginning with LPD 30, which was awarded on March 26, 2019.

In response to the customers’ expressed desire for a platform that is ready to conduct split and disaggregated operations, the LPD Flight II will be a mobile, agile airport, seaport, hospital, command and control node, maintenance and logistics facilities supporting a Marine Air Ground Task Force.

The Navy’s decision to utilize the LPD 17 hull as the foundation for LPD Flight II will result in significant capabilities and affordability. The proven LPD hull avoids the risk that accompanies the introduction of a new ship design while saving cost and shortening time to delivery. That means more warfighting capability for the Navy and Marine Corps faster.

Building on a legacy of proven equipment and systems, LPD Flight II maintains commonality with existing fleet assets to provide added value by capitalizing on existing logistics support, crew training and knowledge base for Sailors and Marines. It is the right ship at the right time to efficiently and affordably meet the needs of our Navy/Marine Corps team.
