The Expeditionary Fighting Vehicle (EFV) (formerly known as the Advanced Amphibious Assault Vehicle (AAAV)) was an amphibious assault vehicle developed by General Dynamics during the 1990s and 2000s for use by the U.S. Marine Corps. It would have been launched at sea, from an amphibious assault ship beyond the horizon, able to transport a full marine rifle squad to shore. It would maneuver cross country with an agility and mobility equal to or greater than the M1 Abrams.
The EFV was designed to replace the aging AAV-7A1 Assault Amphibious Vehicle (AAV),[3] which entered service in 1972,[4][unreliable source?] and was the Marine Corps' number one priority ground weapon system acquisition. It was to have had three times the speed in water and about twice the armor of the AAV, as well as superior firepower. The vehicle was to be deployed in 2015;[5] however, on 6 January 2011, Secretary of Defense Robert Gates recommended the EFV program be canceled.[6][7] The program, which was projected to cost $15 billion, had already cost $3 billion.[8][9]
The Marines asked for the EFV to be canceled in favor of the Assault Amphibian Vehicle Service Life Extension Program and the Marine Personnel Carrier, which itself became phase one of the Amphibious Combat Vehicle.[10]
