The 19500t class destroyer (DDH) is a new helicopter carrier class of the Japan Maritime Self-Defense Force (JMSDF). The ships of this class will be the largest surface combatants of the Japanese navy, superseding the Hyūga class helicopter destroyers in terms of size.

Construction

The Ministry of Defense (MOD) first announced plans for the new class on November 23, 2009. This ship's primary mission is anti-submarine warfare but peacekeeping and disaster relief operations are also being considered.[3]

The ship will be able to carry up to 14 helicopters[citation needed] but 7 ASW helicopters and 2 SAR helicopters are planned for the initial aircraft complement. For other operations, 400 troops and 50 3.5t trucks (or equivalent equipment) can also be carried. The flight deck has 5 helicopter landing spots which allow simultaneous landing or take-off. 2 Phalanx CIWS and 2 SeaRAM are equipped for its defense.[1] The destroyers of this class were initially intended to replace the two ships of the Shirane class originally scheduled to begin decommissioning in FY2014.[3]

Forecast International has reported that some of the design changes with respect to the previous class are intended to support the Bell-Boeing V-22 Osprey and Lockheed Martin F-35 Lightning II aircraft,[4] although neither the MOD or the JMSDF have ever mentioned the possibility of introducing carrier-based aircraft.

The construction of the first ship of the class began in 2011 at an IHI Marine United shipyard in Yokohama.[5] with funding totaling 113.9 billion yen ($1.5 billion) being set aside in the fiscal 2010 budget for this purpose. Launch of the first of class is currently scheduled for 2015.

Ships in the class

In September 2011, The Asahi Shinbun[6] reported that the Ministry of Defence is to proceed with a budget request calling for funds for the construction of the planned second unit in the class. This will come under the Defense Ministry's Mid-Term Defense Program FY2011-2015.
