Japan is also adding longer-range patrol aircraft and military cargo planes to its defence capability, and buying Lockheed Martin F-35 fighter jets, amphibious assault vehicles and Boeing’s Osprey troop carrier, which can operate from the Izumo.
Japan in recent years, particularly under Prime Minister Shinzo Abe, has been stretching the limits of its post-war, pacifist constitution. It has designated the Izumo as a destroyer because the constitution forbids the acquisition of offensive weapons. The vessel, nonetheless, allows Japan to project military power well beyond its territory.
Based in Yokosuka, near to Tokyo, which is also home to the US Seventh Fleet’s carrier, the Ronald Reagan, the Izumo’s primary mission is anti-submarine warfare.
