China’s first domestically-produced aircraft carrier successfully completed its first voyage mission and returned safely and smoothly. This shows that the first domestic aircraft carrier structure, buoyancy, stability, and tightness developed on the basis of our independently established aircraft carrier design criteria and technical standards system have successfully undergone marine navigation verification. The successful completion of the offshore drive test at the power system indicates that China has developed a research and development, design, and construction system for the core equipment of the aircraft carrier power system, control software and system integration, and on-board installation.
