| General information |
|
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.

| Armament |
|
The standard version of the EFV is equipped with a two man turret armed with a Mk44 Bushmaster II 30 mm cannon, which fires up to 250 rounds per minute with single, burst, and fully automatic capabilities up to 2,000 metres (2,200 yd) in all weather conditions. A general purpose M240 7.62 mm machine gun with 600 rounds of ready-to-use ammunition is mounted coaxially with the main gun. The electronically powered two-man MK46 turret on the personnel variant accommodates the commander on the right and gunner on the left, a fire control system, and the main and coaxial weapons. A line of four smoke-grenades discharger is mounted to each side of the turret. The turret is equipped with a compact modular sight developed by General Dynamics which includes a thermal imaging sight, laser rangefinder and Kearfott dual-axis head assembly (DAHA). The DAHA is gyroscopically stabilised to 50mrad in azimuth and in elevation and provides the stabilised line of sight for the weapon fire control system on vehicle.

| Protection |
|
The EFV, designed by General Dynamics Land Systems, is an amphibious armored tracked vehicle with an aluminum hull. The hull provides protection against armour-piercing rounds and fragmentation devices.
|
| Propulsion |
|
The EFV vehicle is powered with an 12 Cylinder Engine MTU MT883 Ka523 Diesel with a power Water Mode of 2800 hp and a Land Power Mode of 850 hp, coupled to an transmission Allison X4560. The EFV is equipped with an retractable hydropneumatic suspension with seven double rubber-tyred road wheels with the drive sprocket at the front and the idlerat the rear, and four return rollers.

|
EFV’s ability to plane at speeds in excess of 20 knots is accomplished by using twin 23” waterjet propulsors. These proven waterjets deliver mission critical power, even in the most demanding sea and surf conditions. The waterjets provide thrust that allows the EFV to acheive excellent stability and superior maneuverability. The rear of the EFV vehicle family is equipped with an hydraulically operated ramp.
