Global Defense Highlights: Strikemaster NMS test in Norway, Chunmoo 3.0 MLRS debut, Shield AI’s X-BAT unmanned jet, France commissions FDI frigate, USS Nimitz sails final mission in South China Sea – Week of October 20–25, 2025.

In Norway, the Strikemaster NMS coastal defense system achieved a critical milestone after clearing a live-fire validation campaign. Developed for rapid deployment and high-mobility coastal denial, the system is designed to counter amphibious and naval threats with precision munitions and sensor fusion. Its validation confirms the platform’s readiness to reinforce NATO’s northern defenses at a time of growing Arctic and Baltic tensions.

In South Korea, Hanwha Aerospace used the stage of ADEX 2025 to unveil the Chunmoo 3.0 Multiple Launch Rocket System, an evolution of its battle-tested MLRS platform. Chunmoo 3.0 introduces longer-range guided munitions, autonomous fire control, and modular launch pods compatible with both Korean and NATO-standard rockets, offering a scalable solution for precision strike and deep fires in high-intensity conflict zones.

In the United States, defense tech company Shield AI lifted the veil on its X-BAT platform, an unmanned, piloted-capable VTOL fighter jet designed to dominate contested airspace. Blending AI-piloted autonomy with fighter-class performance, X-BAT is engineered for missions that range from ISR and strike to air dominance, with vertical takeoff enabling shipboard and remote operations. The system represents a radical leap forward in manned-unmanned teaming for future air warfare.

At sea, the French Navy marked a major modernization step with the official induction of its first FDI-class frigate, Amiral Ronarc’h. Outfitted with Thales SeaFire radar and Aster 30 surface-to-air missiles, the 4,500-ton frigate is optimized for high-intensity, multi-threat environments, offering enhanced anti-air and anti-submarine warfare capabilities. Its entry into service enhances France’s and NATO’s naval reach from the Atlantic to the Eastern Mediterranean.

Meanwhile, the U.S. Navy confirmed the start of the final deployment for the aircraft carrier USS Nimitz, now sailing in the South China Sea. One of the oldest and most storied carriers in the fleet, Nimitz’s presence in the region during its twilight tour underscores Washington’s resolve to maintain freedom of navigation in contested waters. Its operations alongside regional allies come amid heightened tensions with China, as the U.S. shifts toward fielding more distributed and survivable maritime forces.

Together, these five developments from the week of October 20 to 25 illustrate a global defense environment in rapid transition. With militaries investing in mobility, autonomy, long-range fires, and naval resilience, the race for next-generation dominance across all domains has moved from concept to operational reality.
