Sailors aboard Britain's newest aircraft carrier are training to fight through darkness, rough seas, and radio silence

ABOARD A ROYAL NAVY HELICOPTER — Fog hangs low complete Norway's jagged coastline as the British chopper flies out complete the frigid waters below. The days are expanding colder, bringing worsening climate and decreased daylight to the High North.

The helicopter, a Merlink Mk4, lands on the escape phase of the HMS Prince of Wales, the Royal Navy's flagship. Wind whips throughout the phase as sailors bundled in protective equipment move F-35 stealth combatant jets into position.

By first afternoon, the sun is already sinking toward the horizon, complicating operations as the ray fades away.

Business Insider visited the Prince of Wales, the guide container for the UK's transporter attack group, in first November during it was underway in the Norwegian Sea. The ship's deployment is part of the second phase of Operation Firecrest, a deterrence goal in the Arctic and North Atlantic.

NATO is increasingly focused on reinforcing its northern flank amid expanding Russian armed forces action in the region. But functioning there, particularly during autumn and into winter as the days rotate into colder and shorter, presents formidable challenges for allied forces.

The High North is a "complex environment," Capt. Ben Power, the Prince of Wales' commanding officer, stated during an discussion on the ship's bridge.

Winter brings ice, persistent low-pressure systems, and thick fog. The squad have to be prepared for these and trained to run without transmitting radar signals or using broadcast communications, skills Power stated are crucial to improving its "warfighting proficiency."

"All of those things are complex whenever you do it in the High North, far additional so than another parts of the world," he said.

NATO has expanded its patrols and shared operations throughout the Arctic and North Atlantic to detect Russian naval action and indication deterrence.

Western officials have specifically stressed the importance of keeping tabs on Russian submarines, dozens of which are based in Murmansk on the Barents Sea.

To attain the Atlantic Ocean or the Mediterranean and Baltic seas, these submarines typically sail south through the North Sea, or between Greenland, Iceland, and the UK — a strategic chokepoint known as the GIUK gap. For NATO, a powerful existence in this area is critical.

"It's harmless to say that we've seen an addition in Russian action in all domains — so above, on, and particularly below the sea," Power said. "In conditions of an appraisal of their capability," he said, "I think Russia continues to stance a dependable threat."

Western naval officers who earlier said alongside Business Insider aboard a Dutch frigate in the Arctic described how mediocre visibility, coarse seas, and ample swells, particularly in the winter, can effect operations, particularly escape ops.

They stated climate has a straightforward consequence on operations, making it crucial to regularly train in locations that volition test the crew.

Speaking aboard the Prince of Wales this week, Commodore Richard Hewitt, commandant of the UK's transporter attack group, acknowledged the challenges of functioning in the High North but commended the squad for their capability to grip the conditions.

In the archetypal phase of Operation Firecrest complete the summer, the Prince of Wales supported Arctic Sentry, a NATO vigilance goal launched before this twelvemonth to fortify safety in the High North through exercises and patrols.

"This twelvemonth has been focused in the High North," Hewitt said. "I can see that continuing inside the North Atlantic — and fairly rightly so."
