NATO Runs Sub-Hunting Drills Off Iceland Without U.S. Forces for First Time in Decades
NATO allies have held anti-submarine warfare drills in the North Atlantic without U.S. ships or aircraft for the first time in decades, forcing European and Canadian forces to lead defenses around the GIUK Gap, a key route for Russian submarines entering the Atlantic.
NATO has run a rare test of its ability to police the North Atlantic without direct U.S. military support. For the first time in decades, allies held anti-submarine warfare drills off Iceland with no U.S. ships or aircraft, putting European and Canadian forces in charge of tracking Russian submarines.
The exercise focused on the GIUK Gap, the stretch of ocean between Greenland, Iceland and the United Kingdom that Russian nuclear-powered submarines use to enter the wider Atlantic. Western militaries see this route as critical: if hostile submarines pass through undetected, they can threaten military reinforcements, cargo ships and undersea infrastructure that link North America and Europe.
Without U.S. hardware, European and Canadian navies had to coordinate surface ships, maritime patrol aircraft, helicopters and undersea sensors on their own. That involves finding slow, quiet submarines in rough waters, sorting them from civilian vessels and sharing data quickly enough to act on brief sonar contacts.
The stakes go beyond naval tactics. The GIUK Gap also carries container ships, tankers and fiber-optic cables that handle most transatlantic internet traffic and financial data. A submarine operating undetected there can put pressure on those links simply by being present, forcing governments and companies to plan around the risk of sabotage or interception.
The drill comes amid growing concern that Russia is rebuilding parts of its undersea fleet, even as its ground forces are tied down in Ukraine. NATO states have repeatedly warned about increased Russian submarine activity and interest in undersea infrastructure.
The exercise also reflects a gradual U.S. pullback from some European roles as Washington shifts more attention to the Indo-Pacific. For European governments and Canada, it underlines that the North Atlantic cannot be treated as automatically secure and that they must maintain enough ships, aircraft and trained crews to patrol it themselves.
Signals to watch after the exercise include whether NATO members commit to more frequent North Atlantic patrols without U.S. participation, invest in new maritime patrol aircraft and anti-submarine frigates, or publicly highlight unusual submarine or cable-related activity in the region. Those steps would show whether this is a one-off drill or the start of a broader shift in how the alliance defends the Atlantic.
