USS Ponce (AFSB(I)-15) was a United States U.S. Navy amphibious transport dock later converted to an afloat forward staging base and interim Afloat Forward Staging Base (I). Commissioned in the early 1970s, she served across Cold War crises, Operations Desert Shield and Desert Storm, and extended deployments to the Persian Gulf, before conversion and redesignation as AFSB(I)-15 to support United States Central Command operations. Ponce combined amphibious heritage with an experimental forward staging role to support special operations, mine countermeasures, and logistics in contested littoral environments.

Design and conversion

Originally built as an Austin-class amphibious transport dock by Ingalls Shipbuilding in Pascagoula, Mississippi, Ponce embodied design principles shared with sister ships such as USS Austin (LPD-4), USS Cleveland (LPD-7), and USS Duluth (LPD-6). The Austin class featured a well deck for Landing Craft Air Cushion and LCU operations, a flight deck for SH-60 derivatives, and accommodations for embarked Marines and their equipment under doctrines promulgated by United States Marine Corps amphibious assault planning. Hull form, propulsion, and internal arrangements reflected post‑World War II amphibious ship evolution influenced by Operation Neptune evaluations and Amphibious Ready Group concepts.

In 2012–2013, Ponce underwent conversion in Alabama and Virginia shipyards to become an afloat forward staging base, redesignated AFSB(I)-15. Modifications removed the well deck and enlarged deckhouses to create berthing, maintenance spaces, command and control suites, and storage for mine-countermeasure equipment and unmanned surface vehicles. The conversion integrated systems tested by U.S. 6th Fleet, U.S. Navy Expeditionary Combat Command, and contractors working on forward staging concepts that traced conceptual lineage to Sea Base and Mobile Offshore Base proposals. Ponce’s configuration also accommodated aviation assets, Special Operations Command task elements, and mission modules supporting modular fleet operations influenced by Littoral Combat Ship mission-package thinking.

Service history

Following her 1971 commissioning, Ponce joined United States Sixth Fleet and made transits to the Mediterranean Sea, participating in exercises and port visits during Cold War tensions, including interactions with Soviet naval units such as the Soviet Northern Fleet and operations tied to crises in Lebanon and Cyprus. During the 1980s she supported amphibious readiness groups and NATO exercises such as Exercise Ocean Venture and Bright Star in coordination with Egyptan forces.

In 1990–1991, Ponce was mobilized for Operation Desert Shield and Operation Desert Storm, embarking Marines and serving in the Persian Gulf logistics and amphibious posture that deterred Iraqi forces during the Gulf War. Through the 1990s and 2000s she continued amphibious rotations, training with Fleet Marine Force Atlantic, conducting counter‑drug and humanitarian assistance visits in the Caribbean Sea and Central America, and participating in multinational exercises with partners including Royal Navy, Spanish Navy, and Brazilian Navy units.

After conversion to AFSB(I)-15, Ponce was forward-deployed to the U.S. Fifth Fleet area of operations based in Manama, Bahrain. There she provided persistent afloat support for regional operations, integrating with Combined Maritime Forces, Coalition counternarcotics and maritime security patrols, and supporting anti-ISIL related logistics and command efforts.

Operational capabilities and role

As an Austin-class LPD, Ponce provided amphibious lift for Marines, vehicles, and gear using a well deck, vehicle stowage, and flight deck operations supporting rotary-wing platforms such as the Bell AH-1Z Viper-lineage and Sikorsky CH-53 Sea Stallion variants. Her command spaces enabled embarked commanders to plan amphibious assault and expeditionary operations in coordination with Amphibious Squadron and Amphibious Ready Group elements.

Post‑conversion, Ponce’s role shifted to afloat forward staging base duties emphasizing logistics, repair, maintenance, and staging of specialized units. She supported mine countermeasure operations with storage and maintenance for unmanned vehicles, served as a floating repair hub for small combatants and expeditionary craft, and provided command-and-control for task forces operating under U.S. Central Command and CTF-55 constructs. Ponce carried additional berthing to host joint and coalition personnel, enhanced communications suites interoperable with NATO and partner command networks, and embarked detachments from Naval Special Warfare Command and Explosive Ordnance Disposal teams.

Notable deployments and incidents

Ponce’s operational record includes participation in Operation Earnest Will escort missions during the Iran–Iraq tanker war, support roles during Operation Desert Shield/Desert Storm, and extended presence in the Persian Gulf after conversion, where she acted as a staging platform for mine clearance operations and partnered maritime security missions with regional navies. Her presence supported responses to incidents involving IRGCN interactions with merchant shipping and coalition vessels, and she was part of multinational efforts to safeguard navigation through the Strait of Hormuz.

Ponce also served as a testbed for novel concepts, hosting trials of unmanned aerial vehicles, unmanned surface vehicles, and mobile repair teams that informed doctrine used by Littoral Combat Ship squadrons and expeditionary logistics planners. Notable onboard incidents included engineering and stability challenges during conversion and ongoing maintenance periods necessitating coordination with Naval Sea Systems Command and civilian shipyards.

Decommissioning and fate

After more than four decades of service, Ponce was decommissioned on 29 October 2017. The decision reflected hull age, maintenance costs, and evolving fleet priorities under plans advanced by the Secretary of the Navy and Chief of Naval Operations guidance favoring newer platforms such as ESB-class expeditionary sea bases and Littoral Combat Ship mission solutions. Post-decommissioning disposition included striking from the Naval Vessel Register and transfer to disposition processes managed by Naval Sea Systems Command and the Defense Logistics Agency; she was subsequently disposed of through scrapping and recycling in accordance with U.S. naval ship retirement practice.
