How the Dutch Van Speijk frigates served NATO

Where and how did the Dutch Navy use its Type 12-derived Van Speijk-class frigates?

Mostly in NATO standing groups, patrols, and anti-submarine forces supporting the defense of Dutch and allied ports.

The Dutch frigates belonged primarily to NATO-oriented forces tasked with keeping European sea lanes and ports open. Their Type 12 lineage suited the anti-submarine mission that dominated these commitments. They could visit Dutch overseas territories, but that was not their most frequent employment. This short watch point places the class within alliance force structure rather than treating it only as a British-derived design.
