The missile was fired from JDS Kirishima (DDG-174). Read about her here.

Funny as in odd.
South Park (not a fan it was on during shift work) did an episode regarding Hiro tonight.
Actually, the interceptor was fired from the JS Myoko, DDG-175, not the Kirishima. The target, a medium-range ballistic missile, was fired from the Pacific Missile Range Facility in Kauai, Hawaii.
