HMS Duncan

HMS Duncan (D37)

HMS Duncan is the sixth of the highly-capable Type 45 air defence destroyers and one of the most advanced warships in the world. She sails with a ship's company in excess of 280 personnel and is based at Portsmouth Naval Base.

She is the first of the Type 45 class to be capable of deploying Harpoon and was the star of the Channel 5 documentary 'Warship: life at sea". Series 2 is due to air in February 2020.

In 2019 the Portsmouth-based warship completed one of the most varied – and demanding – deployments by a Royal Navy warship in recent years.

The destroyer joined French aircraft carrier Charles De Gaulle as part of the multinational Carrier Strike Group GAN 19 operating off Syria on Operation Inherent Resolve; HMS Duncan provided air defence to the group as part of operations against ISIS forces in the region.

May and June saw HMS Duncan committed to various NATO exercises in delivering humanitarian aid and countering human/arms-trafficking before joining Standing NATO Maritime Group 1 for Exercise Sea Breeze in the Black Sea where, once again, she was employed in her air-defence role and hosted the President of Ukraine, Volodymyr Zelensky.

Little more than two weeks later, she found herself in the Gulf as part of the UK’s response to rising tensions with Iran and the threat to merchant shipping legally plying its trade.

Duncan stepped in while HMS Montrose, which has performed the bulk of the escort duties since July, underwent a short period of maintenance.

In September 2019 she returned home to Portsmouth.
