How does the US Navy free a nuclear submarine trapped under Arctic ice? During ICEX — the Navy's biennial Ice Exercise — Seawolf-class submarines navigate blind for days beneath the Arctic ice cap using only inertial navigation, then surface by punching through three feet of frozen ocean with nothing but a reinforced steel sail.
But the submarine can't do it alone. Weeks before, a team from the Arctic Submarine Laboratory flies onto the ice and builds a temporary camp on a surface that drifts miles per day. They drill core samples, measure ice thickness down to the inch, and lower acoustic beacons that create an underwater navigation grid for the submarine to lock onto from below.
The margin for error is measured in inches — too thick and the sail cracks, too thin and the camp collapses. Once the submarine breaks through, the crew races sub-zero temperatures with chainsaws and steam lines to clear frozen seawater from every hatch and communication mast before the Arctic refreezes everything they just opened.
This is the full process from blind approach to breakthrough — and why it matters more now than ever.
