The Chinese Navy is already the largest in the world, with a fleet of more than 350 ships that includes a fast-growing armada of destroyers, carriers and submarines, a reality which continues to raise concerns with the Pentagon and Navy weapons developers. By the end of this decade, China is expected to operate as many as 400 ships, according to the Pentagon’s 2020 China Military Power report which catalogs the pace and extent of China’s ambitious military modernization. “China is the top ship-producing nation in the world by tonnage and is increasing its shipbuilding capacity and capability for all naval classes,” the report said.
