AAV7A1 (amphibious assault vehicle)

The AAV7A1 family of vehicles now being coproduced by SAMSUNG TECHWIN and United Defense L.P., is the most advanced version of the AAV7/LVT7. The unique vessel-shaped hull design, powerful water jet and powertrain make the AAV7A1 family a highly mobile fleets of amphibious vehicle. They travel 13km/h in the water and 72km/h on the land enabling them to achieve effective ship to shore transporting operations in a variety of adverse seal/land conditions.

The all-welded aluminum hull of the AAV7A1 protects the crew from small arms fire, shell splinters and flash-burns. To suppress residual penetration of shaped-charge munitions, state-of-the arts enhanced applique armorkit (EAAK) has been added to the hull. Other improvements on the AAV7A1 which add to vehicle survivability is the installation of auto fire suppression and NBC protection system.

The AAVP7A1 is equipped with a new upgunned weapon station that is more reliable and provide greater fire-power than previous models. It mounts an MK19 40mm grenade launcher(K4) and an M2 HB CAL 50 machine gun(K6) in coaxial mount. The weapon station allows the gunner to engage targets out to 1,500meters and to traverse a full 360 degree at a speed of 45degree per second.

The improvements incorporated in the AAVP7A1 represent an impressive upgraded performance. The P7A1 carries a crew of three plus 21 combat-equipped troops or 4,536kg of cargo from ship to shore. Effective fire-power is provided by the new upgunned weapon station, and the addition of applique armor, an automatic fire suppression system, bow plane and improved transmission results in a vehicle with superior capabilities. In order to achieve commonality, the improvements developed for the P7A1 have also been adapted to the C7A1 and R7A1.

The C7A1 is a mobile command post for the maneuver element commander and also provides a means to communicate with other units, supporting arms, and logistical support units. The communication system modification is a new state-of-the art design which provides totally secure voice communication. work stations and direct access to the communication system is provided for nine staff persons.

The R7A1 enables vehicles recovery and maintenance functions to be accomplished in the field. Principal equipment includes a hydraulic telescoping crane with 2,721kg(6,000ib) capacity, a 13,605kg(30,000ib) capacity recovery winch, plus cutting, welding, and other portable maintenance equipment.

The Service Life Extension Program offers the opportunity to extend the use of these highly versatile and valuable vehicles well into the 21st century by upgrading the existing vehicle systems to meet the demand of combat mission in the future. The hull and various other components are remanufactured and refurbished, while at the same time new technology advancements in engine and transmission design, firepower, and survivability and reliability factors are incorporated.
