The LH(X) program aims to enhance the U.S. Marine Corps' amphibious capabilities by replacing the LHD class ships. It incorporates lessons learned from the LHA-6 design while meeting the growing demands of integrated Marine Air-Ground Task Forces (MAGTF). Key features include the reintroduction of a well deck and a reduced island design to optimize deck space. With significant increases in deck capacity, the program is expected to procure in FY24 and achieve operational readiness by FY29, supporting modern aircraft like the MV-22 and F-35B.

LH(X)“Systematic approach to an enduring requirement Concept Platform Concept Platform LH(X) Reduced Island Concept (RIC) Program Status Issues • Program will replace all LHD class • Program to enhance amphibious capability and capitalize on lessons learned with LHA-6 design. • Meet increased demand of total MAGTF growth and demand created by MPC, JLTV, MRAP, JMAC, JSF, MV22, and CH53K. • First of two hull forms in a HQMC (P&R) neck-down amphib plan. • During FY-08, USMC/USN will begin discussions on LH(X) which could be LHA(R) Flt 2, ie. Reestablish the well deck and perhaps include a reduced island for additional deck space. As program gains direction, will incorporate as separate Quad hart. • LH(X) is slated for an FY24 procurement • FY29 Operational • Goal for LH(X) will be designed to reincorporate the Well Deck, and retain as much of the aviation enhancements achieved from LHA(R) as possible (expanded hangar/high bay, space arrangements) • RIC: Part of “spiral design” concept • Eliminates need for flight restrictions on spot 5 & 6 increasing clearance btw A/C and ship’s island; MV-22 currently cannot land on spots 5 & 6 on the LHD and LHA-6 • Increases deck capacity 20% over LHA-6 (9 more H46 equivalent spots) which equates to an increase to the standard MEU ACE: • 4 more MV-22B or • 3 more F-35B or • 3 more CH-53K
