Operation Arctic Edge 25 concluded in Alaska after a month-long series of multidomain training drills that tested joint U.S. forces, allied militaries, and interagency partners in one of the world’s most demanding environments.
Readiness Tested in Harsh Conditions
From August 1–31, U.S. Northern Command led the exercise across Alaska, integrating forces from First Air Force, Army North, Naval Forces Northern Command, Marine Forces Northern Command, Special Operations Command North, and Alaska Command.
Participants confronted tidal extremes, unpredictable weather, and austere infrastructure that pushed operations to their limits.
The scope extended beyond U.S. units. Troops and experts from the United Kingdom and Denmark joined the effort, along with interagency partners such as the Coast Guard, FBI, NOAA, and Alaska Native communities.
This diverse participation reflected the complexity of securing the Arctic and the importance of blending military and civilian expertise.
Highlights of Arctic Edge Operations
Forces carried out port seizure drills at Port Mackenzie and Port Northstar, live-fire missile defense engagements, and maritime security missions in the Bering Sea.
Units rehearsed rapid High Mobility Artillery Rocket System (HIMARS) insertions and conducted patrol base operations in austere terrain.
One of the exercise’s most challenging sequences involved explosive ordnance disposal (EOD) divers clearing simulated mines in Cook Inlet. Extreme tidal shifts and near-zero visibility tested both human endurance and equipment reliability.
The team also recovered and analyzed a simulated foreign unmanned underwater vehicle, demonstrating counter-drone procedures in Arctic waters.
Allied and Interagency Integration
The exercise underscored how Arctic security depends on shared awareness and cooperation. A joint Marine Corps and Coast Guard team successfully executed a simulated raid to seize Port Mackenzie, ensuring critical logistics routes remained open.
Army transportation brigades then reopened austere port facilities, proving that sustainment is as vital as initial entry.

Technical Innovations and Research
Arctic Edge 25 advanced more than tactics. It included field tests of space-based radar technology for improved intelligence sharing and cryoacoustics research to study soundwave travel in Arctic waters, supporting submarine warfare and communications.
These innovations, paired with lessons from unmanned underwater vehicle recovery, provide a roadmap for adapting U.S. and allied forces to future Arctic challenges.
By linking operational data with Indo-Pacific Command’s concurrent Northern Edge 25 exercise, commanders also validated cross-theater coordination for simultaneous global crises.
Operational Lessons Learned
Important takeaways emerged from the exercise:
- Logistics in the Arctic hinge on limited infrastructure and narrow tidal windows, making sustainment a decisive factor.
- Multi-agency participation, including NOAA, FBI, and Alaska Native communities, simulated real-world emergency responses beyond combat operations.
Broader Strategic Implications
The Arctic is increasingly central to U.S. homeland defense strategy. Rapid environmental change and global competition with Russia and China are redefining the region’s security landscape. Operation Arctic Edge 25 demonstrated the ability to assure allies, deter adversaries, and defend North America in a contested Arctic.
“Exercises like Operation Arctic Edge 25 strengthen our ability to protect the homeland while building the partnerships necessary for enduring Arctic security,”
a Northern Command spokesperson noted.
How This Shapes Arctic Defense
The exercise made clear that future Arctic operations will rely on both technological innovation and coordinated partnerships. Beyond military readiness, it highlighted how communities, allies, and agencies can combine resources for resilience in extreme conditions.
As lessons from Operation Arctic Edge 25 are integrated into doctrine, U.S. Northern Command and its partners will be better prepared to navigate the emerging strategic importance of the High North.
