随着战略重点从深海大洋转向濒海区域,美国海军正在加紧建造30艘适于濒海作战的“弗吉尼亚”级攻击核潜艇。然而“弗吉尼亚”级潜艇的单价逼近 25亿美元,开发低成本技术正在成为财政紧张的五角大楼急待解决的问题。美海军正在探索未来新一代攻击型核潜艇概念,并对未来潜艇所需的关键技术进行开发,核心要素就是降低成本。 As the strategic focus shifts from the deep ocean to the littoral region, the U.S. Navy is stepping up efforts to build 30 “Virginia” class attack nuclear submarines suitable for the littoral operation. However, the unit price of the “Virginia” class submarine has approached 2.5 billion U.S. dollars and the development of low-cost technologies is becoming an urgent issue for the Pentagon under financial constraints. The U.S. Navy is exploring the concept of a new generation of attacking nuclear submarines in the future and developing the key technologies needed for the future submarines. The core factor is reducing costs.
