the information Figure: Japan a very large helicopter destroyer “Ise the launching ceremony.

Not long ago, in Yokohama, Japan, Ishikawajima-Harima Heavy Industries Group officially started for the Self-Defense Force to build a “helicopter destroyer” – 22DDH. Aboard the largest warship built in Japan after the war, full load displacement of 24,000 tons, a maximum speed of 30; can be loaded with 970 crew and combat troops, capable of carrying up to 14 helicopters. Made another huge breakthrough in the construction of the warship, marking Japan’s large and medium-sized warships with one stone kill many birds with the strategic significance of the development of Japanese sea power.

First, break through the Japanese battleship tonnage limit.

a long time, Japan is constrained by the “peace constitution” can not build offensive weapons, including aircraft carriers, including. To change this situation, as a “normal country”, Japan has developed a series of ship manufacturing plans, and firmly implement. Out to reduce trouble, to reduce the consideration of public attention at home and abroad, will be all kinds of large warships named ship, helicopter destroyers, etc., such as: launching in November 1996, “Osumi transport ship, the standard displacement of 8900 tons; in March 2009 and the service in March 2011 “to” and “Ise” helicopter destroyer “, the full load displacement of 18,000 tons. One year on, Japan began the construction of a displacement of more than 20,000 tons of “helicopter destroyer” – 22DDH. Many naval experts believe that: either tonnage or layout, 22DDH small aircraft carrier is no different. From the development trend, Japan’s future is bound to design the construction of larger tonnage and has a medium-sized aircraft carrier (a displacement of 40,000 tons or more) longer and wider deck.

Secondly, the technical reserves for the future construction of aircraft carriers.

22DDH ship direct flight deck, the captain than to the “class 51 meters long, 248 m; wide ship is 38 meters, 5 meters wide than the latter. In order to facilitate the future aircraft carrier takeoff and landing, 22DDH still maintain a bridge set on the starboard side of the standard carrier. In addition, the ship also carried out three major improvements:

First to lift completely diversion to both sides of the ship’s tonnage increased to enhance the lift 20 tons, it is sufficient to meet the F- 35B and other fixed-wing carrier aircraft.

two is more than defensive weapons (“Hai Lamu” anti-aircraft missiles and the Phalanx close defense weapon system) placed on both sides of this layout is not only conducive to future modification of the Ski Jump flight deck more conducive to the vertical/short-range carrier-based aircraft taking off and landing.

standards and materials of the flight deck improvements: Replacement of a thick high strength steel, still laying on the surface of high temperature materials.

In fact, the deck length and width were significantly increased, coupled with the substantial improvement of the ship deck thickness and material, 22DDH ship is very suitable for the F-35B and other vertical/short aircraft carrier takeoffs and landings.

, again, can significantly enhance the strength of the Maritime Self-Defense Force escort group.

Japanese Maritime Self-Defense Forces jurisdiction four frigates group (early, commonly known as “88 fleet”, later renamed the “90 Fleet”). Since replaced by “to” and “Ise” two frigates group “of the core ship – Haruna-class flagship, its overall strength has improved significantly. However, the other two guard the team’s flagship of the group “still” white roots “level. “White root” class ship the original mission is anti-submarine warfare-based, its functions in line with the needs of the originally proposed 1,000 nautical miles route “of the protection of two. Today, the Japanese Maritime Self-Defense Force is no longer just turned their eyes in the “South East” and “Southwest” two sea routes, but pay more attention to the combat capability of the COSCO sea waters. 22DDH ship can carry a considerable number of helicopters (the future may be switched to the vertical/short takeoff and landing aircraft) is expected to play an important role in a variety of sea and air battlefield.

Fourth, in some respects, Japan gradually get rid of the “shackles and fetters.

United States and Japan, despite the existence of a military alliance, the United States in Japan for a long time in a large number of troops, but this force on the one hand is used to deal with the “common enemy” in the United States and Japan, on the other hand, has oversight and custody “of functions – allow Japan to develop its military capability within a certain range, but not to the” bigger and stronger, and in particular, to strictly limit the Japanese development of large-scale offensive weapons. The United States can provide some advanced weapons to Japan (E-2C early warning aircraft such as F-35 fighter, the E-767 command and control aircraft, ship-based phased array radar, etc.), aircraft carriers and nuclear submarines and other weapons can not let that Japan has. In this regard, Japan’s “obvious”, so they can only take the cover of darkness, back door, gradually broke “strategy, the gradual accumulation of technology, while continuing to amend the constitution to create public opinion, the momentum for the development of aircraft carriers, nuclear submarines and other sensitive equipment.
