Amphibious Warfare Ships

OKINAWA, Japan (March 19, 2018) The amphibious transport dock ship USS Green Bay (LPD 20) transits past the amphibious assault ship USS Wasp (LHD 1) as the ships depart Okinawa, Japan. Green Bay is part of the Wasp Expeditionary Strike Group (ESG), which is operating in the Indo-Pacific region to enhance operability with partners, serve as a ready-response force for any type of contingency and advance the up-gunned ESG concept.

Description: Amphibious warfare ships are the centerpiece of the Navy-Marine Corps presence, forcible entry, and seabasing capabilities and continue to play critically essential roles in global operations. These ships are equipped with aviation and surface assault capabilities that, when coupled with their inherent survivability and self-defense systems, support a broad range of mission requirements.

The United States maintains the largest and most capable amphibious force in the world. Amphibious warfare ships are designed to support the Marine Corps Operating Concept (MOC) and its contained Marine Corps tenets of Operational Maneuver from the Sea (OMFTS) and Ship to Objective Maneuver (STOM). They are able to maneuver in harm’s way and facilitate the rapid employment and sustainment of combat power in the face of opposition. Given their inherent capabilities, these ships will continue to be called upon to support the full ROMO from disaster relief, foreign humanitarian assistance, noncombatant evacuation operations, other crisis response missions, to major combat operations.

Amphibious warfare ships are more than transports. They are versatile, interoperable, warfighting platforms capable of going into harm’s way and serving as the cornerstone of America’s ability to extend sea-power ashore. Amphibious warfare ships provide a force projection and force protection capability that is part of a surface, sub-surface, air, space, and cyberspace networked system to prosecute a naval campaign.

We are a maritime nation. Ships are a critical component of our deployment and employment strategy, and combatant commander demand for amphibious warfare ships far exceeds the available inventory.

The Chief of Naval Operations and the Commandant of the Marine Corps have determined that the force structure required to support the deployment and employment of two MEBs simultaneously is thirty-eight amphibious warfare ships (12 LHD/As and 26 LPD/LX(R)s) to provide seabasing platforms for the TMM force to execute steady state operations supporting the national military strategy and offer the ability to rapidly tailor, deploy, and employ a credible, self-sustained force to respond to crisis.

Our required inventory demand is based on the requirement to:

1. Support the assault echelons of two MEBs.

2. Provide MEUs and SPMAGTFs enduring forward presence and capable crisis response.

3. Improve training and readiness for amphibious warfare.

Requirement is 38 ships.

We must design, build, and operate the best multi-mission amphibious warfare ships in the history of the world. We will improve those platforms to integrate with the next generation Marine Corps and enable it to operate at potential and capacity from the sea base.
