JDS Kaga (DDH-184) is a helicopter carrier (officially classified by Japan as a helicopter destroyer) and the second constructed ship in the Izumo class of the Japan Maritime Self-Defense Force (MSDF).[1][2][3] Her namesake arises from Kaga Province (加賀国 Kaga no kuni?) in present-day Ishikawa Prefecture.


Under construction in March 2015

Kaga is intended to replace the aging Shirane-class destroyer Kurama, based on the schedule outlined within the 23 Mid-term Defence Capability Maintenance Plan to construct a 19,500 ton helicopter destroyer. Construction began at the Yokohama plant of Japan Marine United on 7 October 2013, and the ship was launched on 27 August 2015, with plans for commission in March 2017.[4] Construction of the ship cost 115.5 billion yen.[5][6]


Aircraft carried

The ship can host up to 28 aircraft,[7] or 14 larger aircraft.[8] However, only 7 anti-submarine warfare helicopters and 2 search and rescue helicopters are planned for the initial aircraft complement. For other operations, 400 troops and 50 3.5-ton trucks (or equivalent equipment) can also be carried. The flight deck has 5 helicopter landing spots that allow simultaneous landings or take-offs.

In 2010, Forecast International reported that some design features were intended to support fixed wing aircraft such as the Bell-Boeing V-22 Osprey and Lockheed Martin F-35 Lightning II;[9] although neither the Ministry of Defense nor the Japanese Maritime Self-Defense Force have mentioned the possibility of introducing fixed-wing aircraft. The ship has neither a "ski-jump" nor a catapult, typical features for launching fixed-wing aircraft.[10] If Izumo-class ships were to operate fixed-wing aircraft, it would be limited to STOVL (short take-off, vertical landing) aircraft, such as the F-35B, which Japan may acquire.[11]


The ship is equipped with 2 Phalanx CIWS and 2 SeaRAM for her defense.[12]
