The Swedish military will also contribute one of its ASC 890 surveillance aircraft, made by Saab, and the country's coast guard will deploy four ships.

Sweden's government says the country will contribute up to three warships to a NATO effort to increase the alliance’s presence in the Baltic Sea as it tries to guard against sabotage of underwater infrastructure.

The Baltic Sea operation in the region bordering Russia comes as European fears of sabotage mount after a string of disruptions to underwater cables.
