Royal Navy's new HMS Duncan destroyer enters service

The last of the Royal Navy's six new powerful air defence destroyers has entered service four months ahead of schedule.

HMS Duncan, a Type 45 destroyer, has now joined the fleet alongside its sister ships and will now embark on a programme of trials to prepare the ship and crew for operational deployment.

The 7,500-tonne vessel is armed with the Sea Viper missile defence system which can target threats up to 70 miles away.

The onboard power plant on a Type 45 can supply enough electricity to light a town of 80,000 people.
