核潜艇是指以核能为推进动力的潜艇,与常规动力潜艇相比,具有航速高、自给力大、攻击力强、续航力强、能在水下长期隐蔽活动等优点。自1954年9月美国第一艘核潜艇服役以来,至今各国已建造了500余艘核潜艇,160余艘仍在役。经过40余年的发展,各国共建成了弹道导弹核潜艇、攻击型核潜艇、巡航导弹核潜艇3种核潜艇。作为战略威慑力量的核潜艇,不同的型号和级别都有其独到之处。
Nuclear submarines refer to submarines powered by nuclear energy. Compared with conventional submarines, they have the advantages of high speed, large self-sufficiency, strong attack power, long endurance and long-term hidden activities under water. Since the first nuclear submarine was commissioned in September 1954 in the United States, so far more than 500 nuclear submarines have been built in all countries and over 160 vessels are still in service. After more than 40 years of development, all the countries built a total of three types of nuclear submarines, including ballistic missile submarines, attack nuclear submarines and cruise missile submarines. As a strategic deterrent nuclear submarine, different models and levels have their own uniqueness.
