BAE Systems to arm Marine ACV armored fighting vehicle with 30 millimeter cannon to bolster amphibious assault

QUANTICO, Virginia – US Marine Corps amphibious warfare experts ask BAE Systems to design a high-fire version of the Amphibious Fighting Vehicle (ACV) armed with a 30-millimeter gun as part of an order for 27, $ 8 million announced Friday.

Officials from Marine Corps Systems Command at Quantico Marine Base, Va., Direct BAE Systems Platforms & Services segment in Sterling Heights, Mich., To design and develop phase three of the mission role variant of the ACV medium caliber gun .

BAE Systems is the prime contractor for ACV. The ACV is a wheeled armored fighting vehicle capable of moving marine infantry fighters from offshore ships to navigate invasion beaches.

BAE Systems reportedly selected a version of the medium-caliber MCT-30 turret from Kongsberg Defense & Aerospace in Kongsberg, Norway, for the ACV version. The company is reportedly delivering up to 150 MCT-30 remote turret weapon systems for ACV.

Marine Corps leaders are considering three variations of the ACV – a command and control configuration, a recovery and maintenance vehicle, and a version with a 30-millimeter gun. The MCT-30 turret selected for the ACV is a version of the 30-millimeter gun of the US Army Stryker wheeled combat vehicle.

The 30-millimeter cannon can be effective against lightly armored vehicles, fortified bunkers, helicopters and fixed-wing aircraft. 30-millimeter ammunition generally comes in three varieties: armor-piercing cartridges, highly explosive cartridges, and training cartridges. A 30-millimeter bullet is about an inch wide and six inches long.

The Marine Corps could purchase up to 204 ACVs over the next few years to equip some of its 10 amphibious assault companies. BAE Systems bases its ACV design on the Superav 8×8 amphibious armored personnel carrier developed by the Italian company Iveco Defense Vehicles.

ACV systems are designed to operate through direct, indirect enemy fire and landmines with discreet visual and infrared signatures, modular protection, and other armored vehicle technologies.

Vehicles can swim to shore up to 12 miles offshore, switch from water operations to non-pause ground operations, and then maneuver with M1 Abrams main battle tanks in a mechanized task force. The ACV can destroy relatively light enemy combat vehicles similar to itself.

The ACV will provide direct fire support to the Marines and can carry 17 Marines at speeds of at least eight knots at sea amid three-foot waves with waves as large as three feet.

On land, the ACV has high ground clearance and a V-shaped hull to withstand the effects of landmine explosions, and can operate with a torn off wheel.

Each ACV has a three-person crew, an M2 .50 caliber machine gun at a remote arming station, with the potential to install a stabilized dual-mount M2 / Mark 19 grenade launcher turret, and can now have the 30 millimeter barrel.

Under this contract, BAE Systems will perform the work in San Jose, California; York, Pennsylvania; Kongsberg, Norway; Stafford, Virginia; Bolzano, Italy, and Aiken, SC, and is expected to be completed by July 2022.
