潜艇就其推进动力而言,可划分为常规潜艇和核潜艇两种。所谓常规潜艇,通常系指在水面或通气管状态航行时采用柴油饥推进,在水下航行时使用蓄电池作为动力源的潜艇。潜艇具有隐蔽性和突然性,往往能给敌人以出其不意的致命打击。它在第二次世界大战中战绩显赫,击沉舰艇数位列各种舰艇之首。从而确立了其在各国海军中的重要地位。二战结束后,虽然出现了高性能的核动力潜艇,但并未影响常规潜艇的发展,特别是在冷战结束以后,其发展势头还有上升之势。目前常规潜艇已发展到第三代、甚至第四代。 Submarines in terms of their propulsion, can be divided into two types of conventional submarines and nuclear submarines. The so-called conventional submarine, usually refers to the surface of the water or flue gas state navigation using the propulsion of propulsion, underwater use of batteries as a power source when sailing submarine. Submarines have hidden and sudden, often give the enemy an unexpected fatal blow. It was a prominent player in the Second World War and sunk a few ships to rank the first of various ships. Thus establishing its important position in the navies of various countries. After World War II, despite the emergence of high-performance nuclear-powered submarines, it did not affect the development of conventional submarines. Especially after the end of the Cold War, its momentum of development was still on the rise. At present, conventional submarines have developed to the third generation, and even the fourth generation.
