  China Completes Development of New SSN
  He pointed out that the fourth generation nuclear submarines of the United States and Russia already have these capabilities; China's fourth-generation nuclear submarines too will be equipped with the appropriate torpedoes, along with missiles suitable for use against other sea-going or land-based targets.
  In addition, the Chinese submarine will have low noise output, a key indicator for measuring a modern nuclear submarine's underwater survival capacity, as well as its ability to remain hidden during maneuvers, or undetected while launching an attack. He pointed out that the fourth-generation nuclear submarine will possess effective noise damping features, such as a quieter nuclear power plant with less vibration, and a more advanced hull muffler system, so that it will be difficult to detect even if within range of enemy sonar.
  Analysts believe that continual development of attack submarines and strategic nuclear submarines at times of peace, adding better performance and greater combat ability, can enhance strategic deterrence capability. China's strategic nuclear forces are weapons to deter third parties from becoming involved in local conflicts. China firmly adheres to the principle of non-first use of nuclear weapons, but the existence of strategic nuclear submarines will give China a stronger voice and more room for maneuver in the case of any crisis.
  In addition, Song Xiaojun points out that the United States, Russia, Britain and France all possess modern strategic nuclear submarines as a symbol of their status as 'Great Powers'; it is natural that China should be unwilling to lag behind.
