This is the newest class of destroyers in the Japanese Maritime Self-Defense Force (JMSDF). Built with a high level of indigenous technology, they complement the larger and more capable Atago and Kongo class AEGIS destroyers in service. Their main role is to serve as armed escorts for the JMSDF helicopter carriers. At 6800 tons, they are basically in the same league as a modern European frigate, but Japan classifies them as a destroyer due to its comprehensive weapons and sensor suite. As of now, there are 4 ships of this class, with the final one commissioned in 2014.
