HMS Diamond

HMS Diamond (D34)

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.

Current operation Operation Kipion

Units of the Royal Navy and Royal Fleet Auxiliary have been on patrol in the Gulf since October 1980, after the Iran/Iraq conflict of that year, and more recently operations have extended further south with the increase in piracy off the Somalia coast.

Having warships present in the region is one of the main tools the UK has to show our commitment to this part of the world.

Protecting our economy

Maritime trade is the lifeblood of the UK economy and industry. 95% of Britain’s economic activity depends on the oceans. And every year Britain imports goods worth £524 billion.

The UK is so dependent on the seas for its prosperity, that without the Royal Navy acting as a deterrent the effect on the economy would be overwhelming.

Providing security at sea

The UK has a responsibility to its citizens and its allies to endeavour to safeguard the high seas. This is why the Royal Navy protects home and international waters – making sure the global trade that Britain and the world depend on can proceed without a hitch.
