BEIJING - China's refitted aircraft carrier sailed for its second sea trial on Tuesday, Chinese Ministry of National Defense said in a press release.

According to the press release, prior to sailing, the aircraft carrier has completed all the refitting and testing work as scheduled after its first sea trial on August 10.

The carrier was originally built by the former Soviet Union which named it Varyag, yet failed to complete the ship's construction before collapsing in 1991. The still-unnamed aircraft carrier was an empty shell. Ukraine disarmed it and removed its engines before selling it to China.
