In the 21st century, all countries are committed to investing in new maritime strategies and the construction of naval forces.The PRC navy has been actively building up since the end of the last century,and the development of aircraft carriers has attracted much attention from the international society.Different from the service of various surface ships,the birth of an aircraft carrier represents the transformation of national strategy,showing the military industrial strength and the rise of confidence in major powers.The formation of its combat power may change the situation of the Taiwan Strait and even the global sea power. This thesis adopted the method of document analysis, discussing issues from the change of sea power to the demand for ships,analyzing the combat capability and influence of the People’s Liberation Army’s ships, and extends the performance of the ship’s hull to the attack power of the aircraft to understand how the CCP is performing at this stage.The role of sea power, as well as the threat and influence on our side,are expected to play an important role in the study of related follow-up ships.
