AAV7A1 Amphibious APC

USA

The Amphibious Assault Vehicle 7A1, usually now known as the AAV7A1, was once called the LVTP7A1 by the US Marine Corps and other users. It is a bulky amphibious tracked vehicle intended to land troops on open beaches so it has to be seaworthy and is thus scaled accordingly

Intended as a replacement for the LVTP5 series (see following entry) the first AAV7 (then the LVTP7) prototype appeared in 1967 with production commencing during 1970-71. By the time production had ceased over 1,500 had been produced, not only for the US Marines but also for seven export customers.

The late production model was the AAV7A1 and most earlier models were later brought up to this standard AAV7A1 improvements included a new Cummins diesel engine pack, night vision devices, a new weapon station control system, improved ventilation and many other detail changes. Further improvements are scheduled, including a universal weapon mounting capable of accommodating a 40 mm grenade launcher as well as MGs. The main armament carried on current AAVTAls is a 12.7 mm MG in a small turret on the right-hand side of the engine installation; the driver and commander are seated to the left of the engine.

The capacious troop compartment can hold up to 25 marines or 4.5 tonnes of supplies, with entry and exit being via a large rear-mounted ramp.

In the water, propulsion is provided by two water jet units at the rear. A kit was devised to permit extra applique armour panels to be installed on most US Marine Corps vehicles.

AAV7A1 variants include a command vehicle, a recovery vehicle fitted with a recovery jib, and various mine-clearing vehicles, including one with a mine plough,

Various automotive and suspension test beds have appeared, including a project involving an electric drive system. In time it is expected that the AAV7A1 win be replaced by a programme known as the Advanced Amphibious Assault Vehicle.
