The Kongō-class Guided Missile Destroyer (こんごう型護衛艦 Kongō-gata Goeikan) serves as the core ship of the Japan Maritime Self-Defense Force (JMSDF)'s Escort Flotillas. They are a modification of the United States Navy's Arleigh Burke-class (Flight I). Constructed in the 1990s, the Kongō-class are equipped with the Aegis fire control system, being one of the few ship classes outside of the United States to have that capability.

In the 2010s, the Kongō and Atago-classes were modified to serve in a theater missile defense role, with the primary intention of countering North Korean ballistic missiles.
