  • 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.[13][14]

    Operational history[]

    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.[15] 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.[16]

    HMS 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.[17] Diamond continued undergoing sea trials until she entered operational service in July 2011 after the completion of her trials. The ship will conduct operational training before commencing her first overseas deployment.[14] Diamond is expected to commence deployment in the summer of 2012,[18] starting with celebrations to mark the Diamond Jubilee of Her Majesty Queen Elizabeth II.[19]

    Recent service[]

    Diamond was in the Middle East Area of Operations in 2012 and will be fully ready for operations in 2014.[20]

    Advanced air-defence[]

    The Type 45 destroyers are primarily designed for anti-aircraft and anti-missile warfare with the capability to defend against aircraft, drones as well as supersonic sea skimming anti-ship missiles.[21] The Royal Navy describe the destroyers mission as "to shield the Fleet from air attack". The Type 45 destroyer uses the sophisticated Sea Viper air-defence system[22] utilizing the SAMPSON active electronically scanned array multi-function air tracking radar, and the S1850M long-range air surveillance radar. The Sea Viper system is able to control and coordinate several missiles in the air at once, allowing several tracks to be intercepted. It has been suggested that the SAMPSON radar is capable of tracking an object the size of a cricket ball travelling at three times the speed of sound.[23] A core component of the Type 45's Sea Viper air-defence system is the Aster missile, composing of the Aster 15 and Aster 30. MBDA describe Aster as an anti-missile missile capable of intercepting all types of high performance air threats at a max range of 120 km (Aster 30).[24] The Aster missile is autonomously guided and equipped with an active RF seeker enabling it to cope with "saturated attacks" thanks to a "Multiple engagement capability" and a "high rate of fire".[24] Presently the Daring-class destroyers are equipped with a 48-cell A50 Sylver Vertical Launching System allowing for a mix of up-tp 48 Aster 15 and 30 missiles. However, the Type 45 destroyer was designed to accommodate a total of 64-cells, while some reports suggest a total of 72-cells.[21]

    Ship's sponsor:

    Official affiliations:

    • The Worshipful Company of Barbers[25]
    • The Worshipful Company of Makers of Playing Cards[citation needed]
    • No. 3 Squadron RAF[25]
    • De Beers (UK)[25]
    • The Lordswood CCF (Combined Cadet Force) Naval Contingent will be affiliated once the ship is completed.[citation needed]

    As part of her affiliation with Coventry, Diamond will carry a cross of nails created from the remains of Coventry Cathedral. At the end of the Second World War a cross of nails was created out of the wreckage and has been presented to all ships that carry the name Coventry. It was recovered from the wreck of HMS Coventry by divers after she was sunk in the Falklands War and presented to the crew of Diamond on her commissioning by Captain David Hart-Dyke, the commanding officer of Coventry at the time of her sinking.[13]

    The City of Sheffield was offered affiliation to Diamond, but this was turned down by Sheffield City Council and the Lord Mayor, who want the city associated with another Sheffield.[26] The affiliation has now been transferred to the City of Coventry.[27][28]
