The amphibious assault vehicle (AAV) is employed to conduct mechanized operations and related combat support in subsequent operations ashore.

The AAV is capable of open ocean operation from offshore shipping through rough seas and plunging surf; and without modification, it is capable of traversing beaches, crossing rough terrain, and performing high speed operations on improved roads. AAVs provide the ground combat element (GCE) with armor protection as well as land and water operation capabilities.

The AAV was not designed as an infantry fighting vehicle (IFV) and should not be employed as such. It lacks the armor protection, stabilized weapons station, low silhouette, and means for the infantry to fight from the vehicle without exposing themselves to direct fire.

Enhanced Applique Armor Kit (EAAK)

The EAAK consists of a series of bolt-on armor panels that provide additional armor protection to the vehicle. With the EAAK mounted, the vehicle receives a substantial increase in ballistic protection. The EAAK adds 4,400 pounds (1,996 kg) to the vehicle. The EAAK mounts to the AAVP7A1, AAVP7A1 (RAM/RS), and AAVC7A1 but not the AAVR7A1.

• Protection for vehicle side and slope, troop compartment overhead, and slope rack kit for sponson stowage of OEM.

• Attachment: boss and joint offset method.

• Material: homogeneous harden steel, rubber, mild steel composite.

• Boss offset from hull (no armor): 0.75 inch per side.

• Maximum offset from hull: 8.50 inches per side.

• No penetration for 7.62mm and smaller weapons at muzzle velocity.

• 95% probability of no penetration for 12.7mm armor piercing at muzzle velocity.

• 95% probability of no penetration for 14.5mm at 300 meters.

• 99% probability of no penetration for 155mm HE at 50 feet.

• Substantially decreases the effectiveness of shape charge weapons by reducing the fragmentation debris cone from 110° to 35°.
