HMS Diamond will be formally commissioned into the Royal Navy fleet on Friday.
Hundreds of guests, including families of the 190-strong ship’s company, will attend a colourful ‘christening’ ceremony at Portsmouth Naval Base.
Diamond – the third of six Type 45 destroyers built for the Royal Navy – came to Portsmouth in September last year and has conducted sea trials to ready her for service.
Principal guests on Friday will be the ship’s sponsor, Lady Johns, and the navy’s second in command, Commander-In-Chief Fleet Admiral Sir Trevor Soar.
HMS Diamond’s Commanding Officer, Commander Ian Clarke, will read a Commissioning Warrant and the ceremony will be rounded off in traditional Royal Navy fashion with the cutting of a commissioning cake.
The next Type 45 to come to Portsmouth will be the fourth, HMS Dragon, which is due to arrive in September this year.
