ABOARD THE HNLMS LUYMES—Belgian Navy Commander Erik Kockx was patrolling the Baltic Sea recently when he got word that a ship on NATO’s watchlist was acting in a suspicious manner. After leaving a Russian port, it had slowed down while passing near a pipeline on the sea bottom. The Luymes sailed toward the tanker to investigate.

Kockx leads a task force in the North Atlantic Treaty Organization’s new mission to police the inland sea that its members share with Russia. NATO in January launched the operation, dubbed Baltic Sentry, after a string of undersea cables and pipelines were damaged by ships—many with links to Russia—that had dragged their anchors.

“We are functioning as security cameras at sea,” said Kockx, whose usual duty is clearing unexploded mines from the busy waterway.
