CNN:
China on Friday launched its third and most advanced aircraft carrier from Shanghai's Jiangnan Shipyard.
Named "Fujian," the ship is China's first domestically designed and built catapult aircraft carrier.
Its catapult-assisted launch system is a major upgrade from the less advanced ski jump-style system used on the Liaoning and the Shandong, its two predecessors.
