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.

这是美国海军陆战队唯一的收购类别（ACAT）I收购计划。高级两栖攻击车（AAAV）代表USMC的签名任务。真正的两栖车辆，将取代USMC的老化电流系统并提供操纵的能力，装有船用步枪小队的战斗，以20-25节的速度和机动越野越野越过，其敏捷性和移动性等于或大于M1主战车（MBT）。AAAV实际上将彻底改变USMC战斗行动的各个方面。它是世界上最有能力的全能武器系统之一。已经证明了满足这些要求的技术，并采用该系统代表了满足USMC要求的最有效的解决方案。

AAAV将允许海军和海军陆战队无缝地将船只和动作岸上的操纵连接起来，从而从海中进行操作（OMFTS）。AAAV将是装甲保护的土地和水上流动性的主要手段，并在战斗行动期间为海洋步兵提供直接火灾支持。基于这种独特的任务概况，AAAV必须利用水上推进，土地流动性，致命性和生存能力的最先进状态。AAAV的主要技术挑战是成本且在操作上有效且可获得的轻巧组件和结构。目前有1,322辆USMC突击两栖车辆（AAV7A1）将在下一个世纪末期从1,013个AAAVS取代。

海军陆战队需要采购1,013个AAAV。在1994年12月之前，开发和采购AAAVS的成本估计为72亿美元（当时的美元）。由于预算的限制，国防部在1994年12月将FYDP的AAAV资金减少了1.89亿美元。结果，海军陆战队将示范和验证阶段延长了22个月，并将采购延迟了2年，这将计划的成本增加了4.56亿美元，增加了4.56亿美元，至76亿美元。结果，从2003财政年度到2005财年，低利率的初始产量已推迟。从2006年至2008财政年度的初始运营能力；并充分运作能力 - 围场 - 所有这些都需要AAAVS才能在2012年至2014年的2012财政年度到活动的积极攻击两栖动物和海上介词中队。
