Video Above: How the US Navy Can Fast-Track Building 500 Warships

By Kris Osborn - President & Editor-In-Chief, Warrior Maven

The new Marine Corps Amphibious Combat Vehicle is now operational and preparing to deploy from US Navy big-deck amphibs from miles off-shore into hostile territory, a long-anticipated development expected to bring commanders an unprecedented ability to both travel from ship to shore and extend penetrating land-attack deep into enemy territory.

The Corps is going to deploy its new BAE Systems-built ACV as a way to bring new assault strategy and tactics into the modern era. The new amphibious attack ship-to-shore combat vehicle, is intended to massively expand mission length for amphibious assaults well beyond the current AAV - Corps Amphibious Assault Vehicle.

The new configuration is aligned with an emerging Navy-Marine Corps amphibious assault strategy which, among other things, sees a possible need for extended penetration into land defenses after an initial beachhead is taken.

The new vehicle is designed for long-range sea-land combat operations; it uses ocean water to cool the engine so as to enable it to carry up to 200 gallons of fuel - enough for a 365-mile mission. While the new ACV can travel roughly 13 miles through water, at about six knots, from ship to shore, it can hit speeds of 60mph on land for hundreds of miles inland.

Unlike existing tracked AAVs, the new ACVs are 8X8 wheeled vehicles engineered for greater speed, maneuverability and survivability on land. By removing the need for torsion bars, a wheeled-vehicle such as the ACV can build a v-shaped hull for additional protection, speed and combat durability, BAE Systems developers said.

The new vehicle weighs 30-tons and has a digitized driver’s instrument panel. The existing new ACVs are armed with .50-Cal Machine Guns, and engineered with an unmanned turret that can integrate a 30mm gun, should the Corps request that. It also makes use of a stronger 700hp engine, compared to the AAVs 400hp engine.

The introduction of the new ACV into the fleet aligns with the Navy and Marine Corps’s emerging strategic approach to amphibious attack aimed at leveraging 5th-Generation air support, launching more dispersed, disaggregated yet “networked” assaults and using smaller unmanned vessels to perform reconnaissance, countermine and attack missions. 

A more dispersed amphibious attack force not only reduces vulnerability to enemy fire but can also use advanced C4ISR and networking to better identify key points of attack across a wider area. This amphibious approach is consistent with the Marine Corps vision outlined in services’ recently published Force Design 2030.

The emerging ACVs will launch from big-deck amphibs, called LHAs, and Amphibious Transport Docks, called LPDs. With one of the upcoming LHA America-class amphibs bringing back the well-deck, the Corps plans to emphasize ship-to-shore water-launched combat vehicles. 

At the same time, Navy leaders emphasize that the first two America-class amphibs, LHA 6&7, are built with an aviation emphasis to, among other things, capitalize upon the F-35B and other key air-launched elements of amphibious attack. These aviation-centric big-deck amphibs are intended to pave the way toward the upcoming LHA 8 - which brings back a well-deck.

The entire strategic and conceptual shift is also informed by an increased “sea-basing” focus. Smaller multi-mission vessels, according to this emerging strategy, will be fortified by larger amphibs operating as sovereign entities at safer distances. Corps leaders explain that these big-deck amphib ships would operate as “seaports, hospitals, logistics warehouses and sea-bases for maneuver forces.”

Additional land attack firepower and survivability seem aligned with the Corps newer, more "dispersed" amphibious assault strategy; if amphibious incursions occur in narrow, more spread-apart scenarios, landing forces will potentially need to engage in more land-fighting without large numbers of forces nearby. They will likely rely more upon air support, long-range fires and "networked" intelligence from other ISR nodes, command and control ships or elements of the force - to find and exploit landing areas most advantageous to the attacking force.
