From 4 Flotillas to 3: Inside the Japan Maritime Self-Defense Force’s Historic Overhaul

The Diplomat – In March 2026, the Japan Maritime Self-Defense Force (JMSDF) will undertake its most sweeping organizational restructuring since its establishment in 1954. The “Fleet Escort Force” (護衛艦隊), created in 1961 and long regarded as the backbone of Japan’s surface fleet, will be formally dissolved. In its place, the JMSDF will establish a new “Fleet Surface Force” (水上艦隊). At the same time, it will stand up an “Information Warfare/Operations Command” (情報作戦集団), integrating intelligence, cyber, and oceanographic functions into a unified operational nerve center.

What Iran’s Naval Exercise With China And Russia In The Strait Of Hormuz Actually Means

The War Zone – As the U.S. flows assets toward the Middle East, including the Gerald R. Ford Carrier Strike Group (CSG) now reportedly off the Moroccan coast, Iran, China and Russia will hold their recurring joint naval training exercise in the Strait of Hormuz, according to Iranian media.

The case for enhancing the Royal Navy’s 30mm gun

Navy Lookout – Small and medium calibre guns have quietly become some of the most operationally relevant weapons in Royal Navy service. While missiles dominate discussions of high-end naval warfare, it is guns that provide the persistent, affordable and flexible means to deter, warn and defeat close-range threats. In recent years, that role has expanded dramatically as uncrewed aerial and surface systems have proliferated and increasingly appeared in real combat.
