Admiral Zheng-He - 7 voyages ( 1405-1407, 1407-1409, 1409-1411, 1413-1415, 1417-1419, 1421-1422, 1431-1433 ). The first featured a fleet of 317 vessels. 62 of these were of the largest “Treasure Ship” class and were 440 in length with a displacement of 3,100 tones and a cargo capacity of 2,500 tons. The rest of the ships ranged down to a minimum length of 200 feet ( by comparison the mighty Spanish Armada of 1588 included 137 ships, only 7 of which had a capacity of greater than 1,000 tons ). These vessels were “mega-junks” that featured such advances as compartmentalized hulls separated by waterproof bulkheads and external stern-post rudders moved by mechanical steering devices for precision maneouvering. The admiral’s expeditions all included a complement of between between 20,000 and 30,000 sailors and soldiers( depending on what expedirion we’re considering ). The Portuguese would have dropped a load in their pants if they had seen something like this headed at them
.
These voyages visited Vietnam, the Straits of Malacca, various Indonesian states, both coasts of India, Ceylon, the straits of Hormuz and the Persian Gulf, the Red Sea, the southern coasts of the Arabian penninsula, and the East African coast between Mombasa and Mogadishu.
They ended with the Admiral’s death - partly because of fiscal concerns and partly because of an increasingly isolationist tenor at the Ming court.Thereafter the Ming govt. stuck to smaller vessels for coast defense and local shipping. But independent Chinese traders that had travelled those same routes for centuries before Zheng-He continued to do so.
And I should point out that the Sung had a huge navy. So did the Mongol Yuan dynasty, as we recall from the attempted amphibious invasions of Japan and Indonesia.
The Europeans won out at sea ( big time ) through a combination of technology and fortuitous timing ( including the fortuitous timing of technological discoveries ). And even then their mastery was hardly complete, even later in the game. The Omani Arabs expelled the Portuguese from their most valuable East African real estate in the 17th century ( the present day coasts of Kenya and Tanzania - the last linchpin Portuguese fort in that region, Fort Jesus in Mombasa fell in 1695 I believe ) and limited them to the backwater of Mozambique. A Chinese Warlord expelled the Dutch from Taiwan in 1662 ( only to be expelled in turn by the Manchu Ch’ing force in 1683 that included 300 vessels and 20,000 men ). Etc.
