JS Chokai is a 9,500-ton Kongō-class Aegis destroyer that will be upgraded in the United States for Tomahawk missiles integration.

The US Navy is hosting Japan’s Aegis destroyer JS Chokai for a yearlong training and upgrade program to integrate Tomahawk cruise missiles — a first for the Japanese fleet.

The deployment follows a January 2024 agreement between Tokyo and Washington to acquire 400 Tomahawk missiles.

Japan’s Ministry of Defense said that JS Chokai successfully carried out a dummy Tomahawk loading drill at Yokosuka before departing for the US.
