Designed to replace the Corps' aging Amphibious Assault Vehicle (AAV - in service since 1972), the ACV will be the primary means of tactical mobility for the Marine infantry battalion at sea and ashore (Figure 2). The ACV will possess ground mobility and speed similar to the M1A1 tank during sustained operations ashore and have the capability to provide organic, direct fire support to dismounted infantry in the attack. The ACV will support expeditionary mobility capability and capacity with balanced levels of performance, protection and payload. There are currently four ACV variants planned: (1) a Personnel Variant, which can carry three crew members with 13 Marines and two days of combat equipment and supplies; (2) a Command and Control Variant; (3) a Recovery Variant; and (4) a 30-mm Gun Variant. 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.

Current Program Status In June 2018, the ACV entered Low-Rate Initial Production (LRIP) with BAE Systems selected for the first 30 vehicles to be delivered in fall 2019. In November 2020, the ACV achieved Initial Operational Capability (IOC). In December 2020, a Full-Rate Production (FRP) decision was reportedly made by the Marine Corps after having been delayed from September 2020 due to issues related to Coronavirus Disease 2019. The current planned acquisition objective of 632 ACVs would replace AAVs in Assault Amphibian battalions. The previous acquisition objective of 1,122 ACVs was reduced in accordance with Marine Corps Force Design 2030 modernization efforts (see CRS Insight IN11281, New U.S. Marine Corps Force Design Initiatives, by Andrew Feickert). Reportedly, ACV production is to take place at BAE Systems facilities in Virginia, California, Michigan, South Carolina, and Pennsylvania. Low-Rate Initial Production (LRIP) is a programmatic decision made when manufacturing development is completed and there is an ability to produce a small-quantity set of articles. It also establishes an initial production base and sets the stage for a gradual increase in the production rate to allow for Full-Rate Production (FRP) upon completion of Operational Test and Evaluation (OT&E). Full-Rate Production (FRP) is a decision made that allows for government contracting for economic production quantities following stabilization of the system design and validation of the production process. Initial, Oper ational T stin Observations During Marine Corps initial operational test and evaluation (IOT&E) conducted from June to September 2020, the Department of Defense Director of Operational Test and Evaluation (DOT&E) noted the following: * The ACV demonstrated water mobility and the ability to self-deploy from the beach, cross the surf zone, enter the ocean, and embark aboard amphibious shipping.
