进入21世纪之后,美国海军的主要作战空间将从远洋作战转变为近海沿岸作战,但是按照美国海军目前的发展计划,到2015年前,其水面作战舰艇将只包括DD(X)驱逐舰、“阿利·伯克”级驱逐舰和“提康德罗加”级巡洋舰,这些先进的大型舰艇,单艘平均造价将高达8亿美元以上。尽管它们具有多种作战功能,但因近岸水域的水深过浅、临近陆地以及来自岸上的电子干扰的增加,使得这些舰艇在机动性能和后勤保障能力方面受到很大限制,其先进的作战效能 In the 21st century, the main naval space for the U.S. Navy will shift its operations from ocean-going operations to off-shore operations. However, according to the current plan of development of the U.S. Navy, its surface warships will only include DD (X) destroyers by 2015, “Burke” class destroyers and “Ticonderoga” class cruisers, these advanced large-scale ships, the average cost per single vessel will be as high as 800 million US dollars. In spite of their multiple combat capabilities, the increase in maneuverability and logistical support due to the shallow depths of nearshore waters, the proximity to land and the increase in electronic disturbance from inland waters have led to the limitation of their advanced combat effectiveness
