Eight NATO member countries have launched a five-day submarine detection and tracking exercise in the Baltic Sea, at a time when the alliance considers the security of this area one of its top strategic priorities.
The exercise is taking place in Sweden and will last until Friday, with the participation of naval forces from Great Britain, Canada, Denmark, Finland, France, Germany, the Netherlands and Sweden.
The activity comes at a time when the Baltic Sea has become an important arena for confronting hybrid threats, for which Western countries have repeatedly accused Russia.
The maneuvers involve thousands of naval personnel, German and Swedish submarines, surface warships, and maritime patrol aircraft. The main goal of the exercise is to increase the ability to detect and track submarines, which are considered among the most difficult assets to identify in military operations.
According to NATO, the Baltic presents particular challenges for anti-submarine operations due to its relatively shallow waters and dense maritime traffic, factors that make it more difficult to detect the acoustic signals of underwater vehicles.
NATO's Commander for Submarines, Rear Admiral John Craddock, said that submarines remain one of the most serious threats in the maritime environment.
"The submarine is the only technology that can currently dominate underwater space on a continuous basis. For this reason, it is vital to be able to detect and track them," he said.
According to Craddock, submarine detection skills require continuous training, as it is a skill that can be lost if not practiced regularly.
"We need to train constantly. Until the oceans become completely transparent, submarines will pose a constant threat," he stressed.
On the other hand, French Navy Rear Admiral Nicolas Molitor warned that the Baltic region faces other threats to critical underwater infrastructure.
He said that the vast network of cables and pipelines on the seabed could be at risk not only from submarines, but also from vehicles or robots operating underwater.
Molitor added that even surface ships could cause significant damage if their anchors drag on the seabed, affecting strategic infrastructure running through the Baltic.
The exercise is considered part of NATO's efforts to strengthen maritime security in the region and protect critical underwater infrastructure amid ongoing geopolitical tensions in Northern Europe.
