U.S., Australian, and Japanese forces used a new network to see the same live battlefield picture during a major Pacific exercise, cutting the need to juggle separate systems.
Story Highlights
- Pacific Mission Network gave allies a shared, real-time view during Balikatan.
- Army leaders say partner enclaves now pass data that once stayed siloed.
- Exercises across the Indo-Pacific test the tech in tough, real-world settings.
- Army trials of commercial 5G report command-and-control gains in Hawaii.
What changed during recent Indo-Pacific exercises
Defense officials say the Pacific Mission Network let the United States, Australia, and Japan share a real-time picture of forces during Balikatan. Commanders also sent target-quality data without switching between different workstations, a common pain point in past drills. U.S. Army Pacific’s top general called the mission-partner enclaves an important innovation that finally allowed data to move across nations more easily. These steps aim to speed decisions when seconds matter, especially across long distances.
U.S. Indo-Pacific Command described Valiant Shield 26 as a multinational, multi-domain exercise across Guam, Japan, the Northern Mariana Islands, and nearby waters. The event focused on training that blends air, land, sea, space, and cyber activities among U.S. services and allies. Running the network in these conditions tested how well units share information across vast ranges. It also helped leaders see how coalition pieces fit together when many entities operate at once in the same theater.
How planners are linking sensors, decisions, and fires
Planners for Super Garuda Shield connected tactical and operational communications, data pathways, and intelligence feeds into one shared picture. The Pacific Multi-Domain Training and Experimentation team worked with U.S., Indonesian, and regional forces to bring Next Generation Command and Control together with coalition tactical systems. The goal was to merge data from multiple sensors and platforms so partners can act from the same view of the fight, not from separate screens.
The Super Garuda Shield effort also pushed the system in hard settings. Teams assessed performance in extreme heat and humidity and under limited bandwidth. They looked at how those stresses affect data transport, synchronization, and coalition interoperability. Testing under strain matters in the Pacific, where distance, weather, and scarce infrastructure can break fragile links. If the network holds up here, it is more likely to help in real-world crises where backup options are thin.
Why the Army is experimenting with commercial 5G
The 25th Infantry Division’s Lightning Surge series at Schofield Barracks integrated commercial fifth-generation cellular technology to improve connectivity. The Army reported command-and-control breakthroughs from these trials that support Next Generation Command and Control aims. Commercial fifth-generation cellular networks promise faster speeds and lower delay. If secured and managed well, they can extend data to more users at the edge and cut setup time compared to bespoke military-only systems.
Allied coordination got another check during Tenacious Archer 2026 in Palau. U.S. Soldiers and Marines validated communications networks and command procedures for joint and combined air defense. The event aligned planning and tactical coordination so units could share alerts and responses more smoothly across services and partners. Air defense depends on clear, fast messaging. Proving those links during drills reduces the risk of confusion when a real missile warning arrives.
What remains unclear and what comes next
Public reports so far highlight a shared view, better data flow, and fewer screens to manage. They do not publish measured gains in processing time, targeting cycles, or decision speed. They also center on exercises and experiments rather than operations under attack. That is common for sensitive networks, but it leaves open questions on performance in combat conditions. One brief caveat: officials have not released detailed metrics like latency, uptime, or failure rates.
Independent studies say interoperability is more than cables and code. Coalitions need aligned gear, shared command habits, and agreed processes to work at speed. Training together and building doctrine raise the odds that networks translate into real effects in the field. As allies keep testing in the Pacific, the most useful next steps would be releasing exercise data, stress-testing against jamming and hacking, and showing where legacy manual steps still slow the kill chain.
