Advanced Amphibious Assault Vehicle





  The Marine Corps plans to replace the amphibious assault vehicle with 1,013 advanced amphibious assault vehicles for $6.7 billion, including a $456-million increase due to a 2-year procurement delay. With a water speed of 23 to 29 miles per hour, the new vehicle could be launched from amphibious ships 25 miles or more offshore and reach shore far more quickly than the current vehicle. This improved mobility would reduce the risk to Navy ships from missiles, aircraft, boats, and mines. Until the new vehicle is fielded, beginning in 2008, the Marine Corps anticipates spending more to maintain the current vehicle.

The Marine Corps is developing the AAAV to replace the AAV as its primary combat vehicle for transporting troops on land and from ship to shore. The AAAV must satisfy many operational requirements, which will provide increased capabilities compared to the AAV and improve the ship-to-shore movement, thus allowing the Marine Corps and the Navy to more effectively implement OMFTS. Table 3.1 compares selected AAAV requirements with the AAV's current capabilities.

This is the U.S. Marine Corps only acquisition category (ACAT) I acquisition program. The Advanced Amphibious Assault Vehicle (AAAV) represents the signature mission of the USMC. A truly amphibious vehicle that will replace the USMC's aging current system and provide the capability to maneuver, combat loaded with a Marine rifle squad, at 20-25 knots in the water and maneuver cross country with agility and mobility equal or greater than that of the M1 Main Battle Tank (MBT). The AAAV will virtually revolutionize every facet of USMC combat operations. It is one of the most capable all-around weapon systems in the world. The technology to meet these requirements has been demonstrated, and the plan to procure this system represents the most operationally effective solution for meeting USMC requirements.

The AAAV will allow the Navy and Marine Corps to seamlessly link maneuver in ships and maneuver ashore enabling Operational Maneuver From The Sea (OMFTS). The AAAV will be the principal means of armored protected land and water mobility and direct fire support for Marine infantry during combat operations. Based on this unique mission profile, the AAAV must leverage state of the art advances in water propulsion, land mobility, lethality and survivability. Lightweight components and structures that are cost and operationally effective and supportable together with a significantly more powerful engine are the primary technical challenges for the AAAV. There are currently 1,322 USMC Assault Amphibious Vehicles (AAV7A1 ) which will be replaced by 1,013 AAAVs beginning late in the first decade of the next century.

The Marine Corps has a requirement to procure 1,013 AAAVs. Prior to December 1994, the cost to develop and procure AAAVs was estimated at $7.2 billion (then-year dollars). Due to budget constraints, DOD reduced AAAV funding in the FYDP by $189 million in December 1994. As a result, the Marine Corps extended the demonstration and validation phase 22 months and delayed procurement by 2 years, which increased the program's cost by $456 million, to $7.6 billion. As a result, low-rate initial production has been delayed from fiscal year 2003 to 2005; initial operational capability from fiscal year 2006 to 2008; and full operational capability--fielding all required AAAVs to the active assault amphibian battalions and the maritime prepositioning squadrons--from fiscal year 2012 to 2014.

AAAV──美海軍新型兩棲突擊車

  美國通用動力公司地面系統部為美國海軍陸戰隊研制成功了一種先進的兩棲突擊車（AAAV）。

    AAAV兩棲突擊車設計新穎，在結構上采用滑行車體。滑行車體型車輛的水上運動與賽艇相似，不是靠浮力支持車體在水面上滑跑，從而使車輛獲得較高的速度。采用伸縮性液氣彈簧懸挂裝置，水上行駛時可回縮至緊貼車體位置，以此來減少滑行阻力，彈出后又便于陸上行駛。車體采用由鋁合金和玻璃纖維強化塑料制造的復合材料，并附加了一些鋁合金裝甲塊，防護能力很強。

    該突擊車戰時全重33．8噸，乘員3名，可搭載18名全副武裝的海軍陸戰隊員。該車陸上行駛能力和越野機動力可與M1“艾布拉姆斯”坦克相媲美，其最大時速可達72公里，最大陸上行程482公里。它的水上行駛時速可達46公里，最大行程120公里，大大優于現役的兩棲戰車。AAAV兩棲突擊車上裝備有一門30mm“大毒蛇”Ⅱ型機關炮和一挺7．62mmM240型并列機槍，此外還配有“陶”式反坦克導彈系統，其火控系統為全解式火控系統，車上的電子設備也十分先進，裝備有包括衛星通信在內的多波段無線電台、全球衛星定位系統、AN／VSQ─1型雷達等，具有較強的指揮控制能力，能較好地滿足未來戰爭的需要。

    AAAV兩棲突擊車的作戰特點是實現了超視距突擊登陸，突擊登陸部隊可在離岸40公里或更遠的艦船上下水，向敵海岸防御薄弱地域發起快速、突然的立體突擊登陸，從而使傳統的三階段兩棲突擊登陸方式（艦上機動、由艦到岸的機動和岸上機動）變為兩個階段，即艦上機動和由艦到岸上目標的機動，使突擊行動更加突然、迅速。
