NATO conducts anti-submarine drills in the strategic Greenland-Iceland-UK corridor

During Exercise Northern Viking 26, NATO's Standing Maritime Group One and Standing Mine Countermeasures Group One teamed up with US forces to rehearse anti-submarine operations in the Greenland-Iceland-UK gap, a historically sensitive passage for undersea threats. The scenario relied on layered acoustic techniques, including passive listening for engine and propeller noise, active sonar pings, and networks of sonobuoys dropped from aircraft.

Fixed hydrophone stations on the seabed added persistent monitoring of the area. Surface vessels, submarines, and maritime patrol aircraft worked in concert, reflecting NATO doctrine that no single platform can sustain a contact alone. The drill underscored the evolving technical challenges of hunting stealthy submarines as both detection systems and undersea platforms become more sophisticated.

Historical references noted that only India has sunk a submerged submarine in combat since World War II, illustrating the difficulty of neutralising underwater threats. Overall, the exercise demonstrated NATO's commitment to safeguarding a vital Atlantic choke point against modern submarine incursions.
