HMS Duncan, the final Type 45 destroyer, is expected to make an unscheduled call at the docks on Friday for a weekend visit.

She will be the first Type 45 destroyer to come alongside in Falmouth. Duncan entered service with the Royal Navy on March 22 this year but has yet to be commissioned into the Fleet.

Harbour and sea trials have been undertaken with the vessel now embarking on extensive combat system sea trials and training throughout 2013, to be ready to undertake operational tasking along with her sister ships around the globe.

Britain’s six Type 45 destroyers are the most advanced warships the nation has ever built. Their mission is to shield the Fleet from air attack using the Sea Viper missile which can knock targets out of the sky up to 70 miles away if necessary.

Duncan is the seventh vessel in the Royal Navy’s history to be named after the 18th Century naval commander Admiral Lord Adam Duncan who is famed for his victories at sea. The ship’s motto, secundis dubusque rectus, means ‘upright in prosperity and peril’.
