United States Navy amphibious warfare is the set of naval capabilities, platforms, units, doctrines, and historical practices used by the United States Navy to project power from the sea onto land, enable United States Marine Corps operations, and support joint and combined expeditionary campaigns. Evolving from 18th‑century littoral raiding through 20th‑century large-scale amphibious assaults, it integrates specialized United States Naval Aviation assets, surface and amphibious ships, and landing craft to seize, sustain, and enable littoral objectives. Its development has been shaped by landmark operations, interservice rivalry and cooperation with the United States Marine Corps, and technological advances in seals, airlift, and command, control, communications, computers, intelligence, surveillance and reconnaissance.

History

Origins trace to early American littoral operations and influences from the Gallipoli Campaign and Franco-Prussian War era maneuver thinking, culminating in codified practice between the world wars influenced by the Mahanian doctrine, Naval War College, and lessons from World War I. Amphibious concepts matured in World War II through campaigns such as Operation Torch, Battle of Tarawa, Battle of Guadalcanal, Battle of Iwo Jima, and Battle of Okinawa, where coordination among the United States Army, United States Marine Corps, Royal Navy, and Royal Australian Navy refined assault, logistics, and shore bombardment methods. The Korean War saw the strategic implementation at the Inchon Landing, altering Cold War posture and expeditionary planning, while Vietnam War operations experimented with riverine and littoral interdiction in coordination with Army of the Republic of Vietnam. Post‑Vietnam, amphibious doctrine adapted to nuclear era contingencies, exemplified by responses during the Cuban Missile Crisis, and later operations in Operation Urgent Fury, Operation Just Cause, Gulf War, Operation Restore Hope, and Operation Enduring Freedom that balanced forcible entry with humanitarian assistance and crisis response.

Organization and units

Amphibious capability centers on the United States Navy's amphibious warfare community and the United States Marine Corps's Expeditionary Forces, linked by Amphibious Ready Groups and Marine Expeditionary Units embarked aboard amphibious assault ships. Key commands include U.S. Fleet Forces Command, U.S. Pacific Fleet, U.S. Naval Forces Europe-Africa, and the United States Second Fleet reactivation in response to littoral competition. Specialized units encompass Naval Special Warfare Command (including SEAL Team Six and other United States Navy SEALs), Explosive Ordnance Disposal units, Beach Master Units, and amphibious construction battalions (Seabees). In joint organizations, amphibious operations interface with United States European Command, United States Central Command, and United States Indo-Pacific Command for expeditionary planning and force projection.

Doctrine and tactics

Doctrine emerged through publications like Fleet Amphibious Manuals and joint doctrine coordinated with the Joint Chiefs of Staff and the U.S. Marine Corps Warfighting Publication series. Tactics emphasize forcible entry, over‑the‑beach logistics, littoral air supremacy using Carrier Strike Group escorts, and integration with United States Air Force close air support and United States Army long‑range fires. Techniques include ship‑to‑shore movement, vertical envelopment via MV‑22 Osprey and CH‑53E Super Stallion, special operations raids, and deception operations informed by Operation Fortitude‑style masking in earlier allied campaigns. Anti‑access/area denial (A2/AD) challenges from actors like the People's Liberation Army Navy and regional missile threats necessitate cross‑domain integration, distributed lethality, and concepts such as Expeditionary Advanced Base Operations and Littoral Operations in a Contested Environment.

Landing craft and amphibious ships

Platforms range from amphibious assault ships (LHAs, LHDs) like Wasp-class amphibious assault ship and America-class amphibious assault ship, to landing helicopter docks, amphibious transport docks (LPD), and dock landing ships (LSD). Landing craft include the Landing Craft, Air Cushion (LCAC), the conventional Landing Craft Utility (LCU), and new connectors under the Ship-to-Shore Connector program. Surface escorts and logistics ships such as Ticonderoga-class cruiser and Arleigh Burke-class destroyer protect amphibious groups, while aviation assets including F‑35B Lightning II and MV‑22 Osprey provide shipborne strike and lift. Sealift and prepositioning capabilities employ the Maritime Prepositioning Force and Military Sealift Command auxiliaries to sustain extended littoral campaigns.

Training and exercises

Training combines fleet exercises, Marine Corps forcible entry training, and multinational maneuvers like RIMPAC, Baltops, Talisman Sabre, and NATO Trident Juncture. Schools such as the Naval Amphibious School, Expeditionary Warfare Training Group, and Navy Warfare Development Command oversee curriculum, while unit qualifications occur aboard amphibious ships during Composite Training Unit Exercises and Integrated Training Exercise series. Specialized training involves Special Warfare Combatant‑craft Crewmen, live‑fire gunnery, beach reconnaissance with Marine Reconnaissance units, and combined arms rehearsal with Air Force Special Operations Command and allied partners.

Notable operations and engagements

Prominent engagements demonstrating amphibious art include Battle of Normandy (though primarily Allied landings under multinational command), Inchon Landing in the Korean War, Battle of Iwo Jima and Battle of Okinawa in the Pacific Theater, and Operation Torch in North Africa. Later operations spotlight Operation Neptune Spear interoperability, Operation Urgent Fury in Grenada, Operation Restore Hope in Somalia, Operation Iraqi Freedom littoral contributions, and humanitarian responses after Hurricane Katrina and the 2010 Haiti earthquake, where amphibious platforms provided medical, transport, and logistics support. Admirals and planners associated with amphibious doctrine include figures who served at the Naval War College and within the Joint Chiefs of Staff, shaping modern expeditionary doctrine.
