The Liaoning carrier, made from an empty hull of a Soviet era ship, recently left its shipyard in Qingdao in east China to start a new training mission to test its combat capacity as it is prepared to "fight against enemies".
The construction of China's second indigenously-built aircraft carrier is already underway at a feverish pitch.
Liaoning, which had previously been described in Chinese media as a surface platform for tests and training, has now "formally been described as having a real combat capacity," the state-run Global Times said.
The refurbished ship was launched by former president Hu Jintao in 2012.

There are more than 1,000 non-commissioned officers (NCOs) on the Liaoning, and they are the main part of China's aircraft carrier. "Among them, we have 42 Chief Petty Officers with an average age of 40 and experience of serving in the navy for more than 20 years," Li said.
The report did not elaborate on how China plans to use the carrier, but Liaoning is seen as to put more muscle behind the Communist giant's increasing assertive moves in the South China Sea, where territorial claims by neighbouring nations have dogged China's expansionist idea, and where it faces challenges from the US.
The South China sea, through which USD 5 trillion of trade passes annually, has been a centre of dispute between China and Brunei, Malaysia, the Philippines, Taiwan and Vietnam.
Chinese media reports have said that as the construction of the second aircraft carrier picked up pace, China has stepped up preparations to deploy the first carrier force by putting in place a new batch of carrier-based fighter pilots.
With plans to build two more carriers, the PLA as built up its largest carrier-based pilot team after more than three years of intensive training, media reports had said in August.
