Information Warfare Command participated in a Japan-U.S.-Australia trilateral IW Exercise.

From April 10 to 14, 2026, Information Warfare Command (IWC) of the Japan Maritime Self-Defense Force (JMSDF) participated in Blue Spectrum 26-1 in Australia.

Blue Spectrum aims to improve the JMSDF, the United States Navy, and the Royal Australian Navy’s trilateral Information Warfare (IW) cooperation and interoperability. During the exercise, the three countries’ IW specialists enhanced their planning capabilities and technical expertise while deepening their relationships.

Stepping up efforts to ensure our IW capabilities is essential to protect our nation now and in the future. The Self Defense Fleet and the IWC will continue to maintain readiness and capabilities and contribute to peace and stability in the Indo-Pacific region by closely collaborating with allied and partner navies.
