The U.S. Marine Corps is overseeing the evolution of its next-generation Amphibious Combat Vehicle (ACV) 1.1 to augment its Amphibious Assault Vehicle fleet currently receiving a survivability upgrade (AAV SU). ACV 1.1 will rely on a maneuvering capability with ship-to-shore connectors, while a later 1.2 variant will have enhanced amphibious capabilities, including increased water speed and the ability to self-deploy from amphibious ships. By Kevin Hunter, A&M Editor This past March, the Marine Corps took delivery of the first of 10 Marine Assault Amphibious Vehicle prototypes (AAV-SU) Survivability Upgrade of the Corps' legacy Assault Amphibious Vehicles, beginning a rigorous testing period before taking the upgrades into full production. Developmental testing and low rate initial production (LRIP) delivering 52 vehicles for operational test and evaluation and to USMC units. This single-award, firm fixed-price contract to SAIC's previously announced initial contract value of $16 million for the engineering phase of the contract, with a total contract value of approximately $194 million over five years if all options are exercised. Under the contract, SAIC will upgrade AAVs to provide improved protection while gaining back land and water mobility that improves the AAV's ability to fight. Upgrades include armor, engine rebuild to improve horsepower and torque, replace aging transmission, upgrade suspension components, install new water jets, install blast-resistant seats, and upgrade vehicle control, instrumentation and driver interface systems. In November 2015, ACV 1.1 contracts were awarded BAE Systems and Scientific Applications International Corporation (SAIC) to develop prototypes for evaluation. BAE Systems contract was for $103.8 million and SAIC's for $121.5 million, and each company is to build 16 prototypes to be tested over the next two years. Both vendors are expected to start delivering their prototypes in the Spring of 2017 for testing, and the Marines expect to down select to a single vendor in 2018. Initial operational capability (IOC) is expected by the end of 2020, and all ACV 1.1 vehicles are planned to be fielded by the summer of 2023. Plans are to equip six battalions with ACV 1.1s and 392 existing upgraded AAVs. BAE Systems prototype can accommodate 13 Marines and can travel 11.5 miles at about 7 miles per hour (mph) in surf and 65 mph on land. BAE Systems version incorporates a V hull design intended to protect passengers from underside blasts and has external fuel tanks for increased safety. SAIC's version is said to travel 7 mph in water and incorporates a V hull design as well as blast-mitigating seats. The Marines are also conducting a carry-over study of a high speed water studies effort, ACV 2.0, being transferred to the Navy Science and Technology for R&D. "SAIC is on track to build 16 prototypes for the U.S. Marine Corps and anticipates delivery of the first vehicle in Spring 2017," TIP OF THE AMPHIBIOUS SPEAR BAE Systems' ACV 1.1 fully amphibious vehicle offering currently in production at the company's York, PA facility www.tacticaldefensemedia.com 40 | Armor & Mobility September/October 2016 ENHANCEMENTS AND EVOLUTION
