Chinese experts said China is on course to build 5-6 aircraft carriers.
While the first aircraft carrier, Liaoning, is a refitted Soviet-era ship, the second is being built on the same model with more advanced facilities and is likely to enter service in 2020.
The latest carrier, under construction at Shanghai, is based on US models, state-run Global Times reported today.
Based on information released by Chinese defence ministry, the second Type 001A carrier being built at the northeast Dalian port uses the ski-jump technology for aircraft to take off, like the first carrier Liaoning rather than a more advanced catapult technology used by American carriers.

China is looking into catapult technology for the third Type 002 carrier being built in Shanghai, the daily quoted Li Jie, a naval military expert, as saying.
"In other words, 002 is entirely different from Liaoning (001) and 001A, and it will look like a US aircraft carrier rather than a Russian one," Li added.
Official Chinese media have earlier reported about the possibility of a third carrier but it is the first time they have announced that it was being built.
Most advanced carriers use the Electromagnetic Catapult System, or Electromagnetic launcher (EML), to launch fighter jets, but China is also testing steam catapults, Li said.
Chinese media has often highlighted the construction of aircraft carriers as the US deployed aircraft carriers in the disputed South China Sea challenging Beijing's claims.
The US Navy on Sunday announced that an aircraft carrier strike group has begun "routine operations" in the South China Sea. The announcement came despite a warning from China not to interfere with Chinese sovereignty in the region.

Meanwhile, the Liaoning carried extensive exercises in the South China Sea and Taiwan straits. China is ramping up plans to produce J-15 fighter jets to be deployed on the carriers. Some of them are seen exercising on the Liaoning.
China Central Television has reported that the second carrier's scaffold has been removed and a red undercoat has been painted below its waterline. A launch ceremony will soon be held.
"One key difference is the design will be more 'humanised,' which means all personnel on the carrier will enjoy a more comfortable and modern environment," Song said.
However, "there's still a long way to go from its launch to enlistment, which normally takes two years," Yin said.
"Its status can be compared to a house whose paint job has been completed but requires decorating, which, in military terms, is called the 'outfitting stage'," Song said.
A large amount of work remains to be done on the carrier's outfitting stage after it's launched, presumably sometime this year, Li said.
"It will take about one to two years to carry out functional debugging of its devices, weapons and equipment. The new aircraft carrier can begin sea trials by early 2019," he said.
