This ship was one of several in the JMSDF fleet participating in disaster relief after the 2011 Tōhoku earthquake and tsunami.[1]

In late April 2017, the Ashigara along with the JS Samidare joined the US Navy's Carrier Strike Group 1 as the Strike Group moved into position off the Korean peninsula in response to escalating tensions between North Korea and the United States over the DPRK's nuclear weapons program.[2]

The AN/SPY-1 is a United States Navy 3D radar system manufactured by Lockheed Martin. The array is a passive electronically scanned system and is a key component of the Aegis Combat System. The system is computer controlled, using four complementary antennas to provide 360 degree coverage. The system was first installed in 1973 on USS Norton Sound and entered active service in 1983 as the SPY-1A on USS Ticonderoga. The -1A was installed on ships up to CG-58, with the -1B upgrade first installed on USS Princeton in 1986. The upgraded -1B(V) was retrofitted to existing ships from CG-59 up to the last, USS Port Royal.

Atago-class destroyer

The Atago class of guided missile destroyers (あたご型護衛艦, Atago-gata Goeikan) is an improved version of the Japan Maritime Self-Defense Force (JMSDF)'s Kongō class.

Guided missile destroyer

A guided-missile destroyer is a destroyer designed to launch guided missiles. Many are also equipped to carry out anti-submarine, anti-air, and anti-surface operations. The NATO standard designation for these vessels is DDG. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing or dropping it altogether. The U.S. Navy has adopted the classification DDG in the American hull classification system.

In addition to the guns, a guided-missile destroyer is usually equipped with two large missile magazines, usually in vertical-launch cells. Some guided-missile destroyers contain powerful radar systems, such as the United States’ Aegis Combat System, and may be adopted for use in an anti-missile or ballistic-missile defense role. This is especially true of navies that no longer operate cruisers, so other vessels must be adopted to fill in the gap.
