HMS Diamond

HMS Diamond

A jewel in the naval crown, HMS Diamond is the third of the highly capable Type 45 air defence destroyers and one of the most advanced warships in the world.

Add to favourites

Nearly as tall as Nelson’s Column, Diamond's sleek lines are designed for stealth at sea, appearing virtually invisible on enemy radar.

Packing cutting-edge military sensors and a range of potent weapons systems, Diamond is ready to detect and destroy any airborne, surface and sub surface threat.

Her motto befits her name: honor clarissima gemma – honour is the brightest jewel.

She is proud to be affiliated with the cities of Coventry and Aberdeen, and with the Livery Companies the Worshipful Company of Barbers and the Worshipful Company of Playing Card Makers.

On the 31st August 2016, HMS Diamond set sail from Portsmouth to the Southern Mediterranean to replace the Royal Fleet Auxiliary ship RFA Mounts Bay on Operation Sophia for around two months.

Operation Sophia is focused on tackling the human smugglers and arms traffickers who endanger the lives of innocent people. Her focus will be on tackling the movement of arms. She will provide a picture-building capability to help enforce the UN Security Council Resolution prohibiting the trafficking of arms to Libya.
