The Chinese aircraft carrier Liaoning takes a test cruise in May 2012. China formally entered the vessel, its first aircraft carrier, into service on Tuesday, Sept. 25, 2012, underscoring the nation's ambitions to be a leading Asian naval power, although the ship is not expected to carry a full complement of planes or be ready for combat for some time.
