USS Inchon (LPH-12) was an Iwo Jima–class amphibious assault ship of the United States Navy designed to embark, transport, and deploy United States Marine Corps assault forces by helicopter. Built at the Fore River Shipyard by Bethlehem Steel Corporation, Inchon served through the Vietnam War, the Cold War, and multiple peacetime deployments before decommissioning in the 1990s. The ship operated with amphibious ready groups, participated in multinational exercises, and underwent modernization to support evolving aviation and assault doctrines.

Design and construction

Inchon was laid down and constructed at the Fore River Shipyard in Quincy, Massachusetts by Bethlehem Steel Corporation, utilizing the hull form and mission concept of the earlier Iwo Jima-class amphibious assault ships. The design emphasized a full-length flight deck, a large hangar deck, and extensive troop berthing to support deployments of United States Marine Corps battalion landing teams, Marine Medium Helicopter Squadron detachments, and vertical envelopment tactics developed after World War II and tested during the Korean War and Vietnam War. Naval architects incorporated features from CVS conversion concepts, amphibious warfare doctrine, and lessons learned from Operation Blue Bat and Operation Neptune. Inchon's construction reflected industrial practices of Bethlehem Shipbuilding, steelwork standards from American Bureau of Shipping, and shipfitters trained under Maritime Commission programs.

Commissioning and early service

Commissioned in 1970, Inchon reported to United States Atlantic Fleet units and conducted shakedown cruises along the Atlantic Ocean seaboard, visiting ports such as Norfolk, Virginia, Morehead City, North Carolina, and Mayport, Florida. Early operations included amphibious exercises with Landing Craft squadrons, helicopter trials with Marine Aircraft Group squadrons, and interoperability work with amphibious ships like USS Iwo Jima (LPH-2) and USS Boxer (CV-21). The ship integrated procedures from Naval Air Systems Command and Commander, Amphibious Forces, Atlantic Fleet for flight deck operations, cargo handling, and troop embarkation in coordination with Fleet Marine Force, Atlantic.

Vietnam War service

Inchon deployed to the Western Pacific and operated in support of Pacific Fleet and Seventh Fleet operations during the later stages of the Vietnam War. The ship provided rapid air assault capability to support Marine Expeditionary Units engaged in Operation Frequent Wind–era and post-Paris Vietnamization operations, conducting vertical envelopment, casualty evacuation, and logistical resupply missions with CH-46 Sea Knight, CH-53 Sea Stallion, and UH-1 Huey helicopters from attached Marine Medium Helicopter Squadron units. Inchon coordinated with task forces centered on carriers such as USS Enterprise (CVN-65), USS Kitty Hawk (CV-63), and USS America (CV-66), and liaised with units of the Republic of Vietnam Navy, Republic of Korea Navy, and allied navies engaged in operations like interdiction, riverine support, and coastal patrols. The ship also participated in naval gunfire support coordination exercises and amphibious landing rehearsals that drew on doctrine from Amphibious Operations (FMFM 1-1) and reports from Naval History and Heritage Command case studies.

Post-Vietnam operations and peacetime deployments

Following Vietnam, Inchon operated in both the Atlantic Ocean and Indian Ocean theaters, participating in NATO exercises with Standing Naval Force Atlantic units, multinational amphibious training with Royal Navy and French Navy elements, and contingency deployments tied to crises such as Lebanon crisis support planning and Cold War forward presence missions. Ports of call and exercises included visits to Rota, Spain, Gibraltar, Naples, Italy, Souda Bay, and Alexandria, Egypt, and participation in maneuvers with Hellenic Navy and Turkish Navy forces. Inchon provided humanitarian assistance and non-combatant evacuation operations in coordination with United States European Command and United States Central Command tasking when crises demanded rapid helicopter-borne response.

Modernization and refits

During service life, Inchon underwent several overhauls at yards including Norfolk Naval Shipyard and Philadelphia Naval Shipyard to upgrade aviation support systems, habitability, and defensive armament. Refits addressed integration of new aviation fueling systems certified by Naval Air Systems Command, modernized communication suites compliant with Naval Tactical Data System and later tactical data links, and improved damage control measures influenced by Golub-class and Navy overhaul initiatives. Upgrades allowed operation of newer rotary-wing types and improved medical and command-and-control facilities to support Amphibious Ready Group command staffs and embarked Marine Expeditionary Units.

Decommissioning and fate

After more than two decades of service, Inchon was decommissioned and struck from the Naval Vessel Register in the early 1990s amid post-Cold War force reductions and shifting amphibious requirements driven by Base Realignment and Closure and budgetary realignments in Department of Defense planning. The ship was laid up in a reserve status and subsequently sold for scrapping, concluding a service life that followed a trajectory similar to other Iwo Jima-class ships like USS Guadalcanal (LPH-7) and USS Princeton (LPH-5).

Awards and honors

Throughout its career, Inchon and her crew received campaign awards and unit commendations associated with her deployments, including campaign stars for service in Vietnam-era operations, awards from Commander, Amphibious Forces, Atlantic, and commendations tied to humanitarian and joint exercises. The ship's company earned recognition in safety and readiness inspections conducted by Commander, Naval Surface Force, U.S. Atlantic Fleet and operational assessments from Fleet Marine Force, Atlantic.
