HMS Diamond

HMS Diamond

A jewel in the naval crown, HMS Diamond is the third of the highly capable Type 45 air defence destroyers. The ship played a central role in the Diamond Jubilee celebration in 2012.

Highly visible when alongside in Portsmouth with her tall mast, 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.

First declared operational in the summer of 2011, the ship's company completed rigorous training before deploying successful to the Middle East for six months.

The Ship deployed again in January 2014; originally planned to return to the Gulf, the Ship was re-tasked en route to conduct Op RECSYR which stands for the REmoval of Chemical weapons from SRYia.

During this deployment the 8,000 tonne ship operated primarily in the Eastern Mediterranean as part of a Danish-led Danish, Norwegian and British Task Group; her role was to provide protection to the Task Group which included the Ro-Ros carrying the chemical weapons from Syria to their ultimate destination for destruction.

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.

Ready to fight

When diplomacy fails, the UK has to be ready to protect its interests and its allies. What’s more, as a member of NATO and the UN, the UK also acts to support the enforcement of UN resolutions and come to the aid of our allies. This is where the Royal Navy comes in: we train to go where we’re needed – by sea, land or air – and deploy our forces with the aim of restoring peace.
