The submarine, under the leadership of Lieutenant Commander Tobias Eikermann, in the past few weeks has operated under NATO Maritime Command (MARCOM).

The patrol was part of the NATO Assurance Measures focused on monitoring the activities of the Russian fleet. U33 is one of the first German submarines detached to MARCOM for this purpose in the Baltic Sea.

Assurance measures are a sign of the Alliance’s cohesion internally and of its strength and readiness externally; they are a pillar of the NATO Readiness Action Plan going back to the 2014 Wales Summit, where the Allies agreed to increase their presence at NATO’s eastern flank.

“Submarines are a key part of the NATO strategic maritime plan,” said Rear Admiral Andrew Burcher, Commander NATO Submarines. “Deployments like this contribute substantially to sustained assurance measures. We need to ensure that we are capable and ready to defend and protect”.
