The Expeditionary Fighting Vehicle (EFV) (formerly known as the Advanced Amphibious Assault Vehicle) is a developmental U.S. Marine Corps amphibious vehicle, intended for deployment in 2012. The EFV is an amphibious armored personnel carrier; launched at sea, from an amphibious assault ship beyond the horizon, able to transport a full Marine rifle squad to shore. It will maneuver cross country with an agility and mobility equal to or greater than the M1 Abrams. General Dynamics has achieved a true break through in combat vehicle design by providing high water speed, outstanding cross country mobility, fire power and protection in an amphibious vehicle. The Expeditionary Fighting Vehicle (EFV) possesses the ability to launch forces from 20-25 nautical miles out to sea and transport them to shore at speeds in excess of 20 knots (three times the current platform’s speed). EFV provides the elements of flexibility and tactical surprise critical to establish battlefield dominance. Its inherent land mobility will generate uninterrupted momentum to attack the enemy’s critical vulnerabilities. The EFV will replace the current amphibious assault vehicle which entered service in 1972. The current requirement is for 573 vehicles comprising personnel variants (EFVP1) and command variants (EFVC1). In August 2010, the latest prototype of the troubled Expeditionary Fighting Vehicle demonstrates its high speed water manoeuvrability off the coast of Camp Pendleton.

Variants :

EFVC1: Command post variant. The EFVC1 is a command and control platform at battalion and regimental levels and carries the three vehicle crew plus the battalion and regimental staff.
