Japan launches US Tomahawk missile from warship on July 29

Japan conducted a test launch of a U.S.-made Tomahawk cruise missile from the destroyer JS Chōkai on July 29, firing the weapon over the Pacific Ocean. The exercise marked the first time the Japanese Maritime Self‑Defense Force has deployed the long‑range, land‑attack missile from a warship, demonstrating the integration of the system into its existing arsenal.

The trial is part of a broader effort to enhance Japan’s strike capabilities and deepen interoperability with U.S. forces, following recent agreements that allow the transfer of Tomahawk missiles to Japanese platforms. Defense officials noted that the successful launch confirms the missile’s compatibility with Japan’s ship‑board launch systems and underscores the country’s commitment to bolstering its deterrence posture in the region.
