HMS Diamond

**HMS *Diamond*** is the third ship of the Type 45 or *Daring*-class air-defence destroyers built for the Royal Navy. She was launched in 2007, completed her contractor's sea trials in July 2010 and arrived at her base port on 22 September 2010. *Diamond* was commissioned in a traditional ceremony on 6 May 2011, and formally entered service on 12 July 2011.

### Construction

*Diamond*'s construction began at the BAE Systems Naval Ships yard at Govan on the River Clyde in February 2005. She was launched on 27 November 2007.

### Sea Trials

By July 2010, *Diamond* had been fully fitted out and finished her contractors' sea trials (stage 1 trials). She arrived in her base port of HMNB Portsmouth on 22 September 2010.

### Operational Service

*Diamond* was commissioned in a traditional ceremony on 6 May 2011 in her home port of Portsmouth. The ceremony was attended by the ship's sponsor and the Commander-in-Chief Fleet Admiral Sir Trevor Soar. *Diamond* continued undergoing sea trials until she entered operational service in July 2011 after the completion of her trials. The ship conducted operational training before commencing her first overseas deployment. *Diamond* commenced her deployment in the summer of 2012, starting with celebrations to mark the Diamond Jubilee of Her Majesty Queen Elizabeth II.

*Diamond* was in the Middle East Area of Operations in 2012. During Operation Recsyr in February 2014 she escorted MV *Ark Futura* carrying chemical agents from Syria.

On 8 May 2017, *Diamond* performed a demonstration firing of an Aster 30 off the coast of Scotland.

On 4 September 2017, *Diamond* sailed for a 9-month deployment to the Middle East, initially scheduled to relieve HMS *Monmouth*, she was instead diverted to take over as flagship of Standing NATO Maritime Group 2 from sister HMS *Duncan* when her intended relief, HMS *Ocean* was redeployed to provide relief to British Overseas Territories in the Caribbean in the wake of Hurricane Irma. *Diamond* was relieved of her NATO duties upon the return of *Ocean* from the Caribbean on 30 October and resumed her planned deployment to relieve *Monmouth.* However, on 23 November, The Times reported that *Diamond* was being forced to abandon her deployment and return to Portsmouth early due to mechanical issues, which was later confirmed by the Ministry of Defence.

On 10 April 2021, *Diamond* left Portsmouth to conduct a 41-gun salute after the passing of His Royal Highness Prince Philip, the Duke of Edinburgh. The ship flew her ensign at half-mast.

In 2021, the ship initially deployed to the Far East as part of the UK carrier strike group centred on HMS *Queen Elizabeth*. However, she was compelled to detach from the group for repair in July due to reported "technical issues" likely linked to longstanding power and propulsion reliability issues with ships of the class. It was later reported that the ship had "suffered a failure of one of her gas turbines". Repairs were undertaken in Taranto, Italy and at the end of August *Diamond* returned to sea to rejoin the group. In mid-October 2021, after rejoining the strike group, the destroyer again experienced "technical issues", however this time reportedly not related to her propulsion system and was a decision was made to put into Singapore to have them addressed.

In 2023, *Diamond*, with Wildcat embarked, was again escorting *Queen Elizabeth* for her "Operation FIREDRAKE" deployment in northern European waters.
