Quieter, more lethal Russian subs present a new challenge to the US Navy and its NATO partners.
But US and European navies are more than equipped for a renewed emphasis on anti-submarine warfare, the commander of US Naval Forces Europe said this month.


"Their most effective capabilities are their variable-depth active sonars, which have surprisingly long range due to their low frequency and can circumvent the quieting efforts Russia made in the Yasen class because [the sonars] are active," Clark said, referring to the newest class of Russian nuclear-powered subs, to which Burke was also likely referring.

Russian subs reportedly conducted a major exercise in late 2019, testing their ability to reach the North Atlantic without detection. US and NATO navy ships conducted anti-submarine-warfare drills around Iceland in July, and the Navy conducted a similar exercise on its own in the North Atlantic in September.

Those US and NATO exercises reflect concern about what enemy subs roaming the Atlantic could do in a war. In previous conflicts, those subs primarily targeted shipping, but newer, quieter Russian submarines with the ability to launch missiles deep inland add a new threat.

"It's pretty well known now that our homeland is no longer a sanctuary, so we have to be prepared here to conduct high-end combat operations in local waters," Vice Adm. Daryl L. Caudle, commander of Naval Submarine Forces, said during that September exercise.
