There have been some interesting comments, both here and at Instpundit, on my Taiwan invading Taiwan scenarios piece.
First up, some commenters wondered if China would just nuke Taiwan rather than risk the uncertainties of a massive amphibious invasion. That’s never going to happen for the same reason you don’t torch a car you’re planning on stealing. China wants Taiwan not only as a symbol of its own power and territorial unity, but also for its wealth and technological leadership. A Taipei reduced to glowing rubble not only defeats that goal, but would encourage South Korea and Japan (and maybe even Vietnam and the Philippines) to start producing their own nuclear weapons, and might even prod atherosclerotic transnational bureaucracies to actually spring into action to sanction China on a variety of fronts. There are few upsides and an incredible number of downsides to China nuking Taiwan.
Second, as commenter Old Paratrooper noted, this year China launched only its second amphibious assault ship:
The Chinese Navy has now launched a second large amphibious assault ship engineered to carry weapons, helicopters, troops and landing craft into war, a move which further changes international power dynamics by strengthening China’s ability to launch expeditionary maritime attacks.
The ship is described at the second Type 075 Landing Helicopter Dock (LHD), somewhat analogous to the U.S. WASP-class. This Chinese amphibious assault ship reportedly displaces as much as 30,000 tons and is able to carry as many as 28 helicopters, a report from Naval News states. The report adds that the new People’s Liberation Army Navy LHD is likely powered by a diesel engine with 9,000kW, four Close In Weapons Systems and HQ-10 surface-to-air missiles. The new ship’s “aim is likely to increase the “vertical” amphibious assault capability with the very mountainous East Coast of Taiwan in mind,” the Naval News report writes.
The addition of more LHDs certainly increases China’s maritime attack power, making it a formidable threat along the Taiwanese coastline. Photos of the ship show well-deck in back, capable of launching ship-to-shore transport craft similar to the U.S. Navy Landing Craft Air Cushion or newer Ship-to-Shore Connector. Such a configuration makes it appear somewhat similar to U.S. Navy WASP-class which, unlike the first two ships of the America-class, also operates with a well-deck from which to launch large-scale amphibious assaults.
Wikipedia says a third ship of this type is under construction.
Three ships isn’t going to get a Taiwanese invasion done, no matter how advanced, even assuming all the helicopters and landing ships make it to shore. (They wouldn’t.) However, China also has has some 70 other Type 071 through 074 amphibious assault ships in it’s inventory, plus some 200 or so small landing craft, slightly larger than the ones that hit Omaha Beach, some almost 50 years old, many with hovercraft designs. (They have some even older, Soviet-derived crap, that I doubt they’d try to use unless they were really desperate.)
For comparison, the U.S. Navy used over 500 ships during the invasion of Iwo Jima, an island of 8 square miles, as opposed to Taiwan’s 973.
Maybe Chinese planning calls for a massive “set everything moving straight across the straits at once” push, which would explain why only April and October are suitable, because the smaller and older craft simply wouldn’t make it in rougher seas. Such a plan would also only work with massive air superiority over the strait, else they’re asking for a repeat of The Great Marianas Turkey Shoot, only with a lot more target and precision munitions.
Finally, over on Instapundit, user bigfire pointed out that the ChiComs shelled the outpost island of Kinmen (AKA Quemoy) for months. The result? The islanders use the steel from the bombs to make excellent knives:
