Japan Unveils Largest Warship Since WW2 282

schwit1 writes with an excerpt from an AP story on some interesting technology afloat: "Japan on Tuesday unveiled its biggest warship since World War II, a huge flat-top destroyer that has raised eyebrows in China and elsewhere because it bears a strong resemblance to a conventional aircraft carrier. Some experts believe the new Japanese ship could potentially be used in the future to launch fighter jets or other aircraft that have the ability to take off vertically. The ship, which has a flight deck that is nearly 250 meters (820 feet) long, is designed to carry up to 14 helicopters.Though the ship — dubbed 'Izumo' — has been in the works since 2009, its unveiling comes as Japan and China are locked in a dispute over several small islands located between southern Japan and Taiwan. For months, ships from both countries have been conducting patrols around the isles, called the Senkaku in Japan and the Diaoyutai in China."

        Actually, I don't think any current treaties between the U.S. and Japan limit Japanese offensive capability. It's the Japanese constitution which does. Now everybody knows the U.S. is responsible for the non-offensive military part of the Japanese constitution when it was written. That being said they (the Japanese) could change it if they wanted to.

        But they don't, because it's far easier to let the U.S. spend big $$$ on a military along with R&D then it is for them. I'd guess though that if the U.S. ever reduced their pacific capabilities the Japanese would see the light...

                Reliance on obsolete tech is not very comforting. Why should I send a ship to do something that can easily be done with long range land based missiles nowadays? I can afford many, many missiles for the price of your one ship. And when your big toys are at the bottom of the ocean, a few destroyers can easily control the ocean.

                  Carriers exist to project power when it's not a case of total war against a strong opponent (i.e., every conflict since WWII). Nothing else does that job as well - not even close. When war gets hot then of course its the Boomers that matter, and surface ships are irrelevant.

                  Destroyers have never been able to project power - that's never been their mission in the history of navies.

          • In a war between the US and the old Soviet Union, the aircraft carriers weren't expected to last more than a day or two at most. Too many missiles, even if you ignore torpedoes.

            Has China gotten to that level? I doubt it. And there's a lot more stopping them than the threat of an aorcraft carrier or two. Never forget that the US was capable of cranking out one major ship a week 70 years ago when someone got us started.

          • Carrier fleets are not defenseless against subs, infact their defense has centered around sub-based offense. But the Chinese really don't care- not becuase of their sub fleet, which is small and 20 years behind in technology, but becuase of this [wikipedia.org]. These types of missles are far cheaper and much more effective than attack subs.

          According to both Douglas MacArthur and the memoirs of the Japanese prime minister at the time, Kijuro Shidehara, article 9 was written by the prime minister. Because he was afraid that having a weak military would only provide an opening for those wanting to rearm. His answer to that was to preclude that in the constitution. So it was Japanese internal politics rather than the US ramming it down their throats that gave them article 9. Just as their politics have prevented it from being changed. Simply becaue a substantial portion of the Japanese population still supports the idea behind article 9. The current LDP government would like to change article 9 but can't even really push it because their coalition partners, New Komeito, are commited to preserving article 9.

          There is one part of that constitution that I have read was rammed down Japan's throats over the screaming objections of their government. That is the part about equal rights for women. They were not the least bit happy about that.

        Do you think that the US would have the slightest interest in enforcing them? Anything short of strategic nuclear weapons could be brushed off with a 'my, my, Japan's coast guard is looking so robust lately!' unless the US actually has a continued interest in disarming Japan.

        • As someone else said, I was mistaken, and it's Japan's constitution, not a treaty that establishes the defensive nature of their military.

          If it were a treaty, the U.S. has every interest in establishing the appearance of a nation that enforces its treaties, for fear that other nations would flout them.

        Winston Churchill once said that the purpose of NATO is to keep the Russians out, the Americans in, and the Germans down. The US has bases in Japan for the same reason except China==Russia and Japan==Germany. If the American bases are removed, Japan will be forced to re-arm to defend themselves (including nukes), and the Chinese will then feel obligated to do likewise, ... which will then lead to an arms buildup in India and SE Asia. It is far cheaper for the US to maintain the bases than to deal with the consequences of their removal.

      Actually, the U.S. designed it that way. They were the ones who stipulated as a condition of surrender that the Japanese have no standing army (only a "defense force" whose training and armament is tightly-controlled by the U.S.). The U.S. wants a base of operations in the far east, and maintains tight controls over Japan for that purpose. They have other bases in the Pacific, but they set up Japan before long-range aircraft, requiring them to be close to Russia/China/North Korea.

      So no, it's not by choice the Japanese have to rely on the U.S. for military protection. It's a consequence of losing WWII that they're effectively subjugated to U.S. military "protection" (in the same sense of "protection" money).

        Not just with the Japanese, either -- basically, all the other countries in the region are going to have to decide whether they care more about the evil things Japan did to them prior to and during WW2, or about how powerful mainland China is today. Further, the less of a counterweight the US is to China, the more incentive there is for China's neighbors to go nuclear -- and Japan, South Korea, and Taiwan have the technological/industrial base to do so very quickly.

      Be aware tough, that the Japanese navy already has the basic capability of a carrier group. Kongo Class destroyers [globalsecurity.org] are equipped with the SPY-1 phased array radar and the SM2 block 3 missile, the same suite defending American carriers.
      If anything, given the cold war capabilities of the Japanese navy, their carrier group is a bit skewed towards anti submarine warfare, but who's complaining?
      given your original post, I must say that China has no reason to complain. Even if Japan builds another three of these (one for each battle group that it has available now), there's no way that it can mount a credible threat to China itself. It can, tough, be a credible threat against China's expansionary policy in the Spratleys, etc., and above all China's wayward province, North Korea.

Turns out with a few twists of a wrench they make much better bombers than they ever did airliners. Izumo may be a destroyer now, but I guarantee you there are plans - and possibly fittings already installed - for launch equipment.
