Bernard Cole takes a comprehensive look at China's Navy, a Navy that continues to grow while the U. S. Navy shrinks. Of particular note, according to the author, is Beijing's increased attention to guarding its vital sea lanes because of the nation's growing dependence on maritime trade, especially energy supplies. He provides a thorough description of China's naval establishment, including its personnel system, followed by a detailed view of its ships, submarines, and aircraft, all marked by technical sophistication and capability as China reaches the top rank of the world's maritime powers. His evaluation is based on extensive interviews with Chinese and other naval experts, in-depth perusal of original documents, and visits to Chinese warships, training facilities, and shore establishments. The Great Wall at Sea is on the U. S. Navy's Professional Reading List.
