Report to Congress on Marine Corps Amphibious Combat Vehicle

The following is the Oct. 6, 2026, Congressional Research Service report, The Marine Corps’ Amphibious Combat Vehicle.

From the Report

The Marine Corps describes the Amphibious Combat Vehicle (ACV) as a: next-generation, eight-wheeled vehicle designed to move Marines from ship to shore. The vehicle will be the primary means of tactical mobility for the Marine infantry battalion at sea and ashore, replacing the Corps’ aging Assault Amphibious Vehicle. The ACV provides organic, direct fire support to dismounted infantry. The vehicle’s ability to leverage waterways to carry Marines and equipment make it well-suited for various operating environments, including Expeditionary Advanced Base Operations.

Four ACV variants are planned: (1) a Personnel Variant (ACV-P) that can carry 3 crewmembers with 13 Marines and 2 days of combat equipment and supplies; (2) a Command-and-Control Variant (ACV-C); (3) a Recovery Variant (ACV-R); and (4) a 30-mm Gun Variant (ACV-30). The Marines intend for the ACV to provide effective land and tactical water mobility (ship-to-shore and shore-to-shore), precise supporting fires, and high levels of force protection intended to protect against blasts, fragmentation, and kinetic energy threats (see Figure 1 and Figure 2).

The ACV program delivered initial ACV-P variants in November 2020 and delivered initial ACV-C variants in FY2022. Plans call for delivery of Improved Lethality 30-mm Gun Variant ACVs in FY2025 and Recovery Variants in FY2026.
