近年来，人民海军的主战装备迭代迅速，从小艇到巨舰，从单兵到体系，以第四代装备为引领、第三代 装备为主体的现代化人民海军正在形成。海军潜艇部队包括装备战略核潜艇、攻击核潜艇和常规动力潜 艇，是水下重要突击力量，也是人民海军重点发展建设兵种。军事专家曹卫东：我们常规潜艇现在是 AIP系统，就是不依赖空气动力，这样它下潜之后不用经常浮出水面，而且它在水下的隐蔽性能更好， 这是常规的潜艇。作为核潜艇，我们既有攻击型的核潜艇，就是搭载常规武器鱼雷、导弹。我们还有战 略导弹核潜艇，战略导弹核潜艇现在已经可以搭载比较多的战略导弹，那就增加了海基的打击的能力， 所以核常兼备这个角度我们又有亮点。(央视新闻) ...
