3d holland class offshore patrol model - Offshore Patrol Vessel Holland Class by aircube06

The ships are designated offshore patrol vessels, however, considering their size and sensor/radar capacity they are close to corvettes or even frigates, the limited planned armament, however, does not justify this designation.
These ships are armed for low to medium combat activity and patrolling shores, but can also be tasked to patrol in deeper waters like the North Sea or the Caribbean.
