China's first homegrown aircraft carrier will have larger tonnage and carry more carrier-based aircraft, according to military experts.

The second carrier, fully based on China's own design, will have a displacement of 50,000 tons, defense ministry spokesman Yang Yujun told a news conference in Beijing on Dec. 31, 2015.

The design of China's first domestically developed aircraft carrier is similar to the commissioned one Liaoning but its tonnage is larger than Liaoning, said Yin Zhuo, director of the Expert Consultation Committee of the People's Liberation Army Navy and also a member of CPPCC National Committee, during the 2016 Two Sessions on March 6.

Cao Weidong, a researcher at People's Liberation Army Navy's Academic Research Institute, said that stealth technology like radar absorbing materials might be used to manufacture China's second aircraft carrier.

According to Cao, the new homegrown carrier will use homegrown boilers and steam turbines with better performance rather than outdated ones from Varyag used by the Liaoning.

Yin said in an interview during the Two Sessions that the new carrier will be equipped with larger hanger and maintenance garage. He also said that the new carrier will be more capable to store ammunition, oil and water. The new carrier will carry more aircraft and will have better combat ability.

Du Songtao, a military commentator, said that China's first aircraft carrier Liaoning did not expand the hanger by removing the anti-ship missile launchers, but the hanger of the new aircraft carrier will be 10 per cent larger than the old one in the Liaoning by removing the anti-ship missile launchers at the beginning of the design.

Du mentioned that the hangar in the new carrier may be larger than that in French aircraft carrier Charles de Gaulle.

Some fixed equipment and rails take up large space of the hangar in aircraft carrier Liaoning. But according to Cao, lines drawn on the floor should replace these space-consuming equipment in the hangar of the new aircraft carrier.

The builder will expand the flight deck of the new aircraft which will accommodate more aircraft.
