In the midst of a week long NATO exercise the Royal Navy vessel has helped find and recover six historic mines.
Faslane based, HMS Grimsby joined fellow members of NATO Mine Countermeasures Group 1 (SNMCMG1) for Exercise Northern Coast 15.
For a week the minehunter worked with vessels from Belgium, the Netherlands, Norway, Germany, Estonia and Latvia to hunt and recover dummy mines as part of the exercise off the Danish coast.
However in the course of their role play they helped make improvements to navigational safety by discovering and removing six historic mines.
Crew 5, who currently operate Grimsby, led the charge during Exercise Northern Coast, fending off simulated attacks with aggression but also some British flair.
With the aid of her highly trained Clearance Diving team, she recovered a total of five mines during the exercise, a number only equalled by HNOMS Hinnoey, her Norwegian counterpart.
