Pacific Coast, United States : The U.S. Marine Corps has taken another significant step in modernizing its amphibious warfare capabilities with the operational deployment of the new Amphibious Combat Vehicle–Personnel (ACV-P) during ship-to-shore operations conducted from the USS Makin Island off the coast of California.
Marines from 3rd Assault Amphibian Battalion, 1st Marine Division employed the ACV-P while embarked aboard the Wasp-class amphibious assault ship USS Makin Island (LHD-8) as part of Quarterly Underway Amphibious Readiness Training (QUART) 26.2. The January 23 exercise highlighted the Navy–Marine Corps team’s ability to project modernized ground combat power directly from the sea, reinforcing the Corps’ role as the nation’s premier expeditionary force.
According to U.S. Marine Corps officials, the training event demonstrated the seamless integration of the next-generation amphibious vehicle with U.S. Navy amphibious platforms, validating operational concepts central to rapid crisis response and forward-deployed operations.
Modernized Ship-to-Shore Operations
During the exercise, ACV-P vehicles disembarked from the well deck of USS Makin Island and maneuvered through open water toward shore, simulating a contested amphibious landing. The operation required close coordination between Marines and Sailors, emphasizing command and control, ship handling, launch sequencing, and tactical movement from sea to land.
Routine amphibious exercises such as QUART are designed to sustain combat readiness while testing the employment of new platforms under realistic maritime conditions. Conducting these maneuvers at sea ensures forces remain proficient in the complex coordination required for modern amphibious assaults, particularly as platforms and doctrines continue to evolve.
Quarterly Underway Amphibious Readiness Training remains a cornerstone of Navy–Marine Corps interoperability, reinforcing command relationships, communications architecture, and operational procedures essential for projecting force from the maritime domain.
Replacing a Cold War-Era Platform
The Amphibious Combat Vehicle (ACV) represents a generational replacement for the legacy AAV-7A1 Assault Amphibious Vehicle, which had been in service since the early 1970s. While the AAV proved reliable in past conflicts, it faced growing limitations in survivability, reliability, and protection against modern battlefield threats, including mines, improvised explosive devices, and precision fires.
Developed under the Marine Corps Amphibious Combat Vehicle program, the ACV is based on a modern 8×8 wheeled armored vehicle design. This configuration provides improved land mobility, increased reliability, and reduced maintenance demands compared to the tracked AAV, while retaining full amphibious capability.
The ACV is engineered to self-deploy from amphibious assault ships, operate in open-ocean and surf conditions, and transition rapidly into sustained ground combat operations once ashore.
Enhanced Protection and Mobility
In terms of survivability, the ACV incorporates advanced armor solutions designed to defeat small-arms fire, artillery fragments, and underbody blast threats. Compared to its predecessor, the vehicle features significantly improved mine-resistant design, energy-attenuating seating, and modern situational awareness systems that enhance crew and troop safety in high-threat environments.
The ACV is powered by a high-performance diesel engine paired with an independent suspension system optimized for cross-country mobility. Its water propulsion system allows effective maneuvering in shallow waters and surf zones, enabling Marines to move from ship to shore without immediate reliance on landing craft.
The vehicle is fully integrated into the Marine Air-Ground Task Force (MAGTF) network, equipped with modern command, control, communications, computers, and intelligence (C4I) systems that support digitally connected operations during amphibious and inland missions.
ACV-P: Backbone of Amphibious Assault Forces
The ACV-Personnel (ACV-P) variant serves as the primary troop transport within the Amphibious Combat Vehicle family and forms the backbone of Marine Corps amphibious assault formations. Designed to carry a three-person crew and up to 13 embarked Marines, the ACV-P provides protected mobility from ship to shore and onward to inland objectives.
Optimized for infantry transport, the vehicle combines enhanced ballistic and blast protection with advanced situational awareness tools that improve visibility and threat detection. It is typically equipped with a remotely operated weapon station armed with either a 12.7mm heavy machine gun or a 40mm automatic grenade launcher, enabling suppressive fire while maneuvering during amphibious landings and subsequent ground combat operations.
Additional variants entering service include the ACV-Command, providing enhanced communications and battle management; the ACV-Recovery, designed for maintenance and battlefield recovery; and the ACV-30, armed with a stabilized 30mm cannon to deliver direct fire support.
USS Makin Island and Amphibious Power Projection
USS Makin Island plays a central role in enabling these operations. As a Wasp-class amphibious assault ship, it features a well deck capable of launching amphibious vehicles and landing craft, along with a full flight deck supporting helicopters and short takeoff and vertical landing aircraft. This dual capability allows Marine forces to be deployed through both surface and vertical assault methods.
For the U.S. Marine Corps, Wasp-class ships remain essential to amphibious operations, enabling forces to remain forward deployed at sea, reduce dependence on host-nation infrastructure, and provide commanders with flexible response options during crises. The ability to launch ACVs directly from the well deck significantly enhances the speed, protection, and survivability of initial assault waves.
Strategic Implications
Exercises such as QUART 26.2 demonstrate how new platforms like the Amphibious Combat Vehicle are being integrated into existing naval force structures. They validate the Marine Corps’ ability to conduct modern ship-to-shore operations in contested environments, a capability that remains central to U.S. deterrence and global power projection.
The successful employment of the ACV-P aboard USS Makin Island underscores the Marine Corps’ ongoing transition from legacy systems to more survivable, lethal, and expeditionary platforms. By pairing advanced amphibious vehicles with versatile assault ships, the Navy–Marine Corps team continues to refine its ability to respond rapidly to crises and prevail in future littoral and expeditionary conflicts.
