Helicopter destroyer

According to Sam LaGrone, USNI News editor, Japan has launched the second in its new class of helicopter carrier – the largest Japanese ships since World War II – in a Thursday (August 27) ceremony in Yokohama. The 24,000-ton Kaga (DDH-184) – built by ship builder Japan Marine United – bears the same name as the World War II Imperial Japanese Navy carrier Kaga that was part of Pearl Harbor attack and was sunk in the Battle Midway.

The ship follows JS Izumo (DDH-183) which entered service in the Japanese Maritime Self Defense Force (JMSDF) in March. The Japanese have said the primary roles of the two ships are Anti-Submarine Warfare (ASW) and Humanitarian Aid and Disaster Relief (HADR) operations. The ships «heightens our ability to deal with Chinese submarines that have become more difficult to detect», a JMSDF officer told Asahi Shimbum in March.

The ships will field seven Mitsubishi-built SH-60 ASW helicopters and seven AgustaWestland MCM-101 Mine CounterMeasure (MCM) helicopters, U.S. Naval Institute’s Combat Fleets of the World. There is a potential for the two ships to work with American MV-22s and potentially the Short Take-Off and Vertical Landing (STOVL) variant of the Lockheed Martin F-35 Lighting II Joint Strike Fighter (JSF). However, the Japanese say they have no plans to operate the JSF from either ship.

When JS Kaga (DDH-184) commissions Japan will have four helicopter carriers. Along with Izumo, Japan have 18,300-ton Hyuga-class helicopter carriers already in commission.
