Japan’s lethal ‘helicopter-destroyer’: An aircraft carrier in disguise?

(From National Interest)

By Matthew Gamble

The Land of the Rising Sun has been quietly strengthening its military capabilities and procuring advanced equipment amid the ongoing debate over whether to amend Article 9 of the country’s constitution. Though officially called the Japan Maritime Self-Defense Forces (JMSDF), the Japanese Navy boasts an impressive array of hardware and if the country’s ruling party has its way with the constitution, its capability will only get stronger.

To increase the potency of the JMSDF even further, the acquisition of aircraft carriers (CVs) would be a logical next step. Yet, as CVs can best be described as seagoing airbases with significant offensive capabilities, Japan’s pacifist constitution prohibits their use in its navy. Destroyers (DDs) on the other hand rely on speed and maneuverability and are easily employed in defensive roles, criteria deemed acceptable under the Japanese Constitution. Therefore, to accommodate this unique political limitation, the Japanese have designated one of their latest vessels as a “helicopter destroyer” (DDH) but with capabilities akin to those of an aircraft carrier.

Enter the vessel in question: the JSIzumo (DDH-183), commissioned on March 25th, 2015. Officially classified as a $1.2 billion “helicopter destroyer”, this warship is the largest constructed by Japan since the Second World War, and at first glance bears a striking resemblance to a light aircraft carrier. With an impressive length of 248 meters and a beam of 38 meters, the vessel is larger than short take-off and vertical landing (STOVL) carriers operating in the Spanish and Italian navies. Likewise, its fully-loaded displacement of 24,000 tonnes and 7.3 meter draft put the Izumoclass in a category similar to that of the Invincible class carriers commissioned by the Royal Navy. Altogether, the scale of these vessels represents a major advance in Japan’s maritime defense capabilities, significantly increasing the country’s ability to project force. Read more
