Japan Loses One-Third of Global Hawk Fleet in Sea of Japan Crash

Today’s defense news features significant developments in military technology and international security. From drone losses to new weapon systems, here’s a brief look at the key stories.

Japan Loses Global Hawk Drone

Japan’s advanced Global Hawk surveillance drone fleet has been reduced by one-third after one of its RQ-4B Block 30i aircraft crashed into the Sea of Japan on September 15, as reported by Defense News. The Japan Air Self-Defense Force lost contact with the $163 million drone, which had taken off from Misawa Air Base for an unspecified mission, not a training exercise. This loss significantly impacts Japan’s long-range reconnaissance capabilities, though the Japan Maritime Self-Defense Force plans to introduce 23 MQ-9B SeaGuardians starting in 2027.

US Army Acquires Laser Weapon System

The US Army is investing nearly half a billion dollars in a new laser weapon system to counter aerial drones, according to The National Interest. The Army will pay AeroVironment $464.8 million for its Enduring-High Energy Laser (E-HEL) program, which aims to provide a cost-effective counter-UAS solution. AeroVironment will supply dozens of its 30-kilowatt LOCUST X3 laser weapon systems for multi-year fielding, marking a transition of directed energy from experimentation to a fielded capability.

US Navy Orders Hypersonic Weapons

The US Navy has awarded Castelion a contract worth up to $200 million to begin production of its Blackbeard Hypersonic Weapon, Overt Defense reports. This order includes an initial lot of 444 All-Up Rounds, following a previous $23 million order for 50 Early Operational Capability weapons. Blackbeard is designed as a low-cost, air-launched hypersonic strike weapon, with full-capability versions featuring aerodynamic chines for enhanced maneuverability, and is expected to be launched primarily from the Navy’s F/A-18E/F fleet.

US AI Strategy Faces Data Blind Spot

America’s artificial intelligence strategy has a critical data blind spot that could allow China to close the AI gap, according to The National Interest. While the US focuses on protecting chips and models, overlooking advanced training data could be a vulnerability, especially given China’s aggressive open-source strategy and advantages in electricity generation and STEM talent. Although the US held a clear lead in frontier AI a year ago, leading US and Chinese models are now at near parity, necessitating a focus on preventing the transfer of strategically significant capabilities, including advanced training data.

Belarus Reactivates Drone Relays

Belarus has reactivated signal relays that enable Russian attack drones to penetrate deeper into Ukrainian territory, Kyiv Post Defense reports. Ukraine’s State Border Guard Service confirmed the equipment amplifies signals for Russian Shahed and Gerbera drones, allowing them to fly farther into western Ukraine. Border Guard spokesperson Andriy Demchenko linked Belarusian support to a September 13 Russian drone attack near the Yahodyn border crossing with Poland, where drones struck a gas station and a passenger train.
