Former NATO Commander Warns of Escalating Russian Submarine Threat in the Arctic

Russia’s newly developed nuclear-powered submarines are intensifying pressure on NATO’s northern defenses, according to a former alliance commander. The warning highlights Moscow’s pursuit of advanced military capabilities in the Arctic and North Atlantic regions.

The expanding threat also encompasses Russia’s heavily militarized Kola Peninsula, where the Kremlin has bolstered its military infrastructure—including airfields and ports—to fortify its stance along the Northern Sea Route. Additionally, the waters leading to the Greenland-Iceland-United Kingdom Gap, a crucial maritime corridor, remain a focal point.

NATO’s Allied Joint Force Command Brunssum designated the growing Russian submarine threat in the region as “serious” on September 2. The command stated, “Something is moving beneath the surface.”

The alliance noted that Russia is expanding and modernizing its submarine force, with the Kola Peninsula serving as a crucial hub for the Northern Fleet. This includes new-generation nuclear-powered SSGNs equipped with significant long-range strike and sea-denial capabilities.

The Joint Force Command added, “They may be invisible beneath the waves. But not for us. We see them, we watch the developments closely, and yes, we take these developments seriously.”

Retired Gen. Philip Breedlove explained that the combination of quieter nuclear submarines and Russia’s expanding military infrastructure across its Arctic coastline presents an increasingly difficult undersea surveillance challenge for NATO. “Submarines are one of the toughest threats that we have to deal with—they’re very hard to find and track,” he noted.

“Submarines can get well within striking distance of any nation in the Atlantic. From the United States to our NATO allies, submarines can approach close enough to the shore to launch submarine-launched ballistic missiles and cruise missiles, which present a major problem,” Breedlove, the former supreme allied commander Europe for NATO and commander of U.S. European Command, added.

Breedlove noted that nations like Russia and China are currently developing comparable submarine fleets, posing an escalating threat to countries with extensive coastlines. “We’ve taken very capable measures in the past to understand what Russia is doing in those waters, and we will now be adapting to the possibility of a quieter submarine,” he stated. “Any increase in stealthiness or noise suppression by a Russian submarine is, of course, a problem for NATO.”

According to Military Watch and the Russian news agency TASS, Russia’s Yasen-M-class nuclear-powered submarines feature advanced acoustic-quieting and sonar technology. The U.S. Naval Institute reports that these 13,800-ton vessels can carry 1,000-mile-range cruise missiles, anti-ship missiles, and hypersonic anti-ship cruise missiles, with Russian officials asserting they remain “invisible.”

“Yasen-M-class nuclear-powered submarines are capable of accomplishing all of the Navy’s objectives in any part of the World Ocean while remaining invisible,” Russian Navy Commander-in-Chief Fleet Adm. Alexander Moiseyev stated in a June 17 announcement, per TASS. This follows the start of construction on the ninth Yasen-M submarine at Russia’s Sevmash shipyard.

Russia is expanding and modernizing its submarine force, with the Kola Peninsula remaining a key hub for the Northern Fleet.

Breedlove warned, “As is often the case when Putin is in trouble—and he’s in trouble now in his war in Ukraine—one of the ways he diverts attention is to start announcing new super weapons and super capabilities that NATO and the West can’t contend with.”

“Putin is creating a stir about a new class of submarines that he wants to deploy from what we call the bastion waters in the Far North,” he said, emphasizing that NATO “will have to adapt our measures and our ability to see and track them.” “We’ve taken excellent measures in the past.”

Breedlove described the GIUK Gap as a critical gateway for Russian naval forces moving from their northern bases into the Atlantic. “All the Russian ships have to come out through the GIUK Gap to make it into the Atlantic,” he said, warning that the seven other Arctic nations, including the United States, are deeply concerned about Russian activities.

In response to the growing threat, NATO has been reinforcing its northern posture. In February 2026, the alliance launched Arctic Sentry, a multidomain military initiative led by Joint Force Command Norfolk to better coordinate allied land, air, and maritime activity across the Arctic and High North. NATO further bolstered its northern flank in June with Forward Land Forces Finland, a Swedish-led multinational force designed to enhance deterrence and defense along the alliance’s northeastern flank, with Finland serving as the host nation.

“The Arctic region has been a concern for some years now as ice in the area is receding, creating the Northern Passage that allows European trade with Asia to occur much faster,” Breedlove noted, stating that trips are up to 14 days quicker for most ship types. He added, “This is a tremendous economic opportunity, but Russia sees this as an opportunity that they want to control.”

Russia has been upgrading airfields, ports, and radar systems along the Arctic coast as Moscow seeks greater control over the Northern Sea Route and its commercial traffic, Breedlove stated.

The recent NATO buildup has drawn strong pushback from Moscow. Russian Foreign Minister Sergei Lavrov warned on August 30 that increased Western military activity risks destabilizing the Arctic region.

“Such military activity in the Far North poses a direct threat to Russia’s security,” Lavrov wrote in a public essay. He further stated, “It also increases the risk of incidents that could trigger an armed confrontation with potentially disastrous consequences,” according to Reuters.
