Nineteen Nations Rehearse Guarding the Panama Canal
PANAMAX 2026 brings multinational forces together around a waterway that still moves the world's freight
By Solomon "Customs" Bridges
The Panama Canal turns 111 years old this month, and once again the world has come to practice defending it.
Multinational defense and security forces are now fully integrated and training together at PANAMAX 2026, an exercise built around a single, blunt purpose: keeping the canal open. Nineteen partner nations are taking part, according to U.S. Central Command, exercising their collective capacity to maintain security and stability in the region and, by extension, across the Western Hemisphere.
The details of what units are doing, day to day, are thin in the material made available. What is clear is the scale of buy-in: nineteen countries is a wide guest list for any military exercise, and it says something about how the canal is regarded — not as one nation's chokepoint to guard, but as shared infrastructure worth a shared defense.
That matters more than it might seem from a distance. Roughly six percent of world trade passes through the canal each year, by various trade-body estimates, everything from Asian electronics to South American grain to fuel bound for U.S. ports. A disruption there — whether from natural causes, as the drought-driven restrictions of recent years showed, or from a security incident — ripples into shipping costs and shelf prices far from Panama.
We don't have transcripts of what commanders are telling their troops, or a breakdown of which nations sent what hardware. Central Command's release is a snapshot, not a full accounting, and readers should treat it as such. But the headline fact stands on its own: when nineteen militaries agree to drill together over one canal, it is because everyone at the table has decided that canal is worth drilling for.
