核动力巡洋舰(CGN)在美国海军中消失了10余年后即将卷土重来。美国海军眼下已经着手研制新一代导弹巡洋舰CG(X),其中一个备选设计方案就是满载排水量达到2.5万吨、使用核动力推进装置和装备海基拦截导弹的重型核动力导弹巡洋舰CGN(X)。美国海军是世界上最早建造和使用核动力巡洋舰的国家,先后建成服役了5级共9艘核动力巡洋舰,但这些曾经叱咤大洋的水面“核巨鲨”自20世纪90年代中期开始便陆续退出现役,到90年代末已彻底从美国海军中消失了。目前世界上仅有俄罗斯海军还留有2艘“乌沙科夫海军上将”级(原称“基洛夫”级)核动力导弹巡洋舰。美国海军的CGN(X)建成服役后,不仅用于替换现役“提康德罗加”级“宙斯盾”常规动力巡洋舰,而且将成为美国海基导弹防御系统的骨干力量。 The nuclear-powered cruiser (CGN) is about to return after more than a decade of disappearance in the U.S. Navy. The U.S. Navy has now started to develop a new generation of guided cruiser CG (X), one of which is CGN (X), a heavy-duty nuclear-powered missile cruiser that uses 25,000 tons of displacement and uses nuclear-powered propulsion and sea- based interceptor missiles. . The United States Navy is the first country in the world to build and use nuclear-powered cruisers. It has successively built 9 nuclear-powered cruisers of Class 5 in service at a total of 5 levels. However, these once-super-oceanic waters have started to exist since the mid-1990s After graduating from active service, it has completely disappeared from the U.S. Navy in the late 1990s. At present, only the Russian Navy still has two nuclear-powered missile cruisers Admiral Ushakov “(formerly known as” Kirov "). When the U.S. Navy’s CGN (X) is in service, it will not only replace the active Ticonderoga-class Aegis conventional cruiser but will also become the backbone of the U.S. sea-based missile defense system.
