Japan Unveils Largest Warship Since WW2
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, 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).
"If a nation expects to be ignorant and free in a state of civilization, it expects what never was and never will be."
This is a VTOL carrier, through and through. I don't see any significant weaponry on board beyond the aircraft carrying capabilities, and no sources that I can find indicate the armanent of DDH-183 Izumo. Helicopters and VTOL manned and drone aircraft would be ideal uses for that flight deck.
