According to Youth Online “Youth Reference” reported that Japan’s “Asahi Shimbun,” 23, said Defense Ministry prepared to specifications comparable to the construction of light aircraft carrier of the DDH, to “deal with China’s growing naval power.” Against the outside world to the new DDH as a quasi carriers, defense ministry officials said the ship is not taking off and landing of fixed-wing aircraft the ability to use is the anti-submarine warfare and the protection of communication lines, is also not intended to make the introduction of fixed-wing aircraft, because it is not a ship “offensive aircraft carrier.”

Capable of carrying 14 helicopters

“Asahi Shimbun,” the article said it plans to build a DDH displacement was 1.95 million tons, fitted out in March of last year’s “Day to the” No. DDH displacement of 1.35 million tons, is the Maritime Self Defense Force’s largest active-duty warship, but the new DDH, once completed , will take away the title. According to the British “The Telegraph” analysis said the Ministry of Defense plans to buy about 40 US-made F-35 fighter, the aircraft is seen as the future of Japan to build a real aircraft carrier-based aircraft, when appropriate.

Japan’s new DDH long 248 meters wide and 38 meters, the standard equipped with 14 helicopters. As a comparison, the United Kingdom’s “Invincible” was a light aircraft carrier length 206 meters, width of 28 meters, the loaded planes 22. In addition, in order to meet the five helicopters landing at the same time, the new DDH of the bridge will be moved to the starboard side, so that the flight deck to achieve full channel, this layout with exactly the same carrier. This raised a question: whether Japan’s “peace constitution” conflict? In 1988 the Japanese government said in a statement, “As an offensive war potential of the carrier beyond the minimum level of self-defense needs, which the Constitution bans Japan from having such a ship.” Right, “Asahi Shimbun” reporter to mention this issue, the Ministry of Defense found it ridiculous, said the new DDH is a “necessity defense.” A defense ministry official said: “We need to use helicopters as far as possible away from the enemy’s missiles with a range of areas, to find and pay close attention to the submarine. Therefore, the construction of a helicopter can be equipped with multi-DDH is very necessary.” The official said, the new DDH is not a fixed-wing aircraft taking off and landing ability to use is the anti-submarine warfare and the protection of communication lines, is also not intended to make the introduction of fixed-wing aircraft, because it is not an “offensive of the aircraft carrier.”

With the carrier of technical transmission

For a long time, outside Japan, DDH would be treated as “quasi-light aircraft carrier,” because it has a straight-through flight deck and ship-island, with all the characteristics of a light aircraft carrier, as supplemented to build similar to the British “Invincible” aircraft like the 12 degree of slip jump deck, you can take off and land of US-made F-35B fighter. However, the Tokyo Institute of peace and security, Masashi Nishihara, had argued that: “DDH’s flight deck is too thin and unable to withstand the pressure of landing aircraft. For the taking off and landing fighter aircraft, the flight deck of the high temperature capability must be improved, otherwise F -35B fighter aircraft tail pipe heat generated by air will burn deck. In addition, the design was originally parked helicopter hangar lift lifting capacity and layout, are insufficient to meet the requirements to accommodate fixed-wing aircraft. “The implication of this statement yes – DDH only with the carrier a bit quite similar, while in stark contrast to the inherent purpose. Can be seen that Japan’s Asian neighbors to avoid his own DDH said to be an aircraft carrier.

However, Masashi Nishihara argument is questionable. Then built a “day to” No. DDH’s “home” – Ishikawajima-Harima Heavy Industries shipyard site describes the ship “production materials” section, clear the “cycle of cooling pipe with a high temperature, high-intensity large-scale plane plate “content. There is no doubt that this is used to make “day to” was the flight deck material, if used only for the helicopter, you do not have to use such high-grade materials. As to “the flight deck is too thin,” even without Kaopu, Ishikawajima-Harima Heavy Industries shipyard’s own admission, the “to” was the deck of the hardness to withstand more than 30 tons total weight of the MH-53E minesweeping helicopters take off and land, with a total weight is only 20 metric tons of F-35B fighter how can the “inappropriate”? Masashi Nishihara made on the “lift lifting capacity shortage” concerns, the Japanese “world ships” magazine have long said, “Japan to the” deck of the center’s two large numbers, up to 30-ton lift, it may not only for helicopters prepared for this.

The development of aircraft carrier “technology stepping-stone”

The pursuit of perfection on the Japanese national character, any input is a major arms deliberate. Use of terms from the ship, the Japanese service or under construction in the near future of DDH may not be easy to immediately “fade” as the aircraft carrier. Because so far, according to “Japan-US Security Treaty,” the mandate, the Japanese Maritime Self-Defense Force, as the U.S. 7th Fleet’s “auxiliary power” somewhat lower intensity of combat the “blocking and protection of pay” strategy to block Tsushima, Tsugaru, Soya Strait, and the three lines to defend the 1,000 nautical miles as its main task, its first anti-submarine warfare and mine-clearing escort Second, blockade the Straits. This determined the future of Japan’s four destroyers, as the flagship team of the DDH location, nor set off in the past, the Japanese anti-submarine destroyer role aircraft, which can carry up to 16 helicopters, so that the whole formation in the implementation of anti-submarine warfare mission, commander of the hands of Fleet there will be more helicopter patrols.

Overall, DDH should be seen as the precursor to development of the Japanese aircraft carrier, rather than “Japan’s first-generation aircraft carrier.” In 2000, the Japanese cabinet approved the “new defense force and reorganization of the medium-term plan”, the on the confirmation of the next generation of DDH “to retain fixed-wing aircraft equipped with the potential, but currently only equipped with anti-submarine helicopters, most important,” Japan’s Defense Ministry also repeatedly said that there is no the introduction of the Maritime Self-Defense Force fighter jet vertical takeoff and landing plans. Analysts believe that the outside world DDH’s “aircraft carrier the definition of” actually tell the hearts of the Japanese Ministry of Defense mantra – DDH does have all the external characteristics of an aircraft carrier, but in the current international situation, it can become a “first in East Asia aircraft carrier “and a” technical stepping stone. ”
