USMC Amphibian Assault Vehicle-7
The U.S. Marine Corps AAV7A1 Amphibian Assault Vehicle was originally designated the LVT-7 or LVTP-7. It is a full-tracked, amphibious vehicle, providing an over-the-beach capability for landing troops and material through heavy surf. It is the world's only tracked vehicle capable of operating in rough seas and plunging surf up to 10 ft (3.0 m) high. It is the successor to USMC LVTP-5.
The mission of the AAV7A1 dictates its bulk and unusual shape. The vehicle is taller and wider than any other armored personnel carrier (APC). The bow of the aluminum hull has an upturned snout extending well forward of the tracks. Below the nose, the hull flares out in sponsons. This forward section of the hull houses the transmission and engine. The driver and commander are located to the left of the engine compartment, the gunner to the right in a slightly elevated weapons station. Farther aft, the crew compartment can hold 25 troops in three rows; the compartment's upper sides are sloped toward the centerline.
Propulsion is by tracks on land and by twin waterjets in the water. Afloat, the AAV is steered by a deflector's stream at the rear of each waterjet. Secondary track propulsion can be used if necessary.

The history of the LVTP7/AAV7 may be summarized as follows:
Variants of the AAV7A1 include:
The hull length is 26 ft. while the width and height are 10 ft. 9 in. and 10 ft. 8 in. respectively. Ground clearance is 16 inches. Track lenght on the ground is just under 13 feet. Combat loaded weight is 58,105 lbs.
The USMC EFV (Expeditionary Fighting Vehicle, originally named Advanced Amphibious Assault Vehicle until 2003) was expected to replace the AAV7A1 with low rate initial production planned for FY2007. However, further delays with the EFV program stretched to 2011 with full production still years away. In January 2011 it was announced that EFV was cancelled due to budget pressures. Instead, the AAV7 will be upgraded with more armor, better electronics and weaponry.
