The AAV-7: Amphibious Assault Vehicle for Marines
This combat vehicle has the key mission of moving marines from assault ships to the shore. It operates in two environments: it travels on land with its track system and navigates in water thanks to a hull designed like a boat. Its high bow helps it overcome waves when approaching the beach. To propel itself at sea, it uses two waterjets located at the stern, giving it notable water mobility. The crew and soldiers board and disembark mainly through a wide ramp located at the rear. 🚤
Technical Specifications and Design
The AAV-7 measures 7.94 meters in length, 3.27 meters in width, and 3.26 meters in height. Its dimensions and weight allow it to accommodate up to 25 soldiers with all their equipment, plus a crew of three people. Its armor protects the occupants from small arms projectiles and shrapnel. The hull shape not only facilitates navigation but also provides stability when the vehicle travels over complex terrain on land.
Main design features:- Dimensions: 7.94m (length) x 3.27m (width) x 3.26m (height).
- Capacity: Transports 25 marines plus 3 crew members.
- Protection: Armor against small arms and shrapnel.
- Dual mobility: Tracks for land and boat hull for water.
It is the realization of what many imagined when playing with toy vehicles in the water, but with tracks, real armament, and the effective capability to take a beach under fire.
Weapons System and Combat Functions
On the upper section of the vehicle, an armed turret is installed. This turret normally equips a 40 mm Mk 19 automatic grenade launcher and a 12.7 mm heavy machine gun M2. This armament allows the AAV-7 to provide support fire to the infantry it carries on board and counter light threats. The driver and commander operate from their stations inside the armored hull.
Components of its combat capability:- Main armament: Mk 19 grenade launcher (40mm) and M2 machine gun (12.7mm).
- Tactical function: Provide direct fire support during and after landing.
- Control: Crew operates from protected internal stations.
- Aquatic propulsion: Two rear waterjets for agile navigation.
Role in Amphibious Operations
The AAV-7 constitutes a fundamental link in sea-to-land assault operations. Its ability to transition between the aquatic and terrestrial environments without the need for auxiliary boats makes it a versatile asset. Beyond just transporting, its integrated armament allows it to actively participate in combat, securing beachheads and protecting infantry during the most critical phases of the landing. Its design responds to the need for a protected transport with its own firepower. ⚔️
