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.[23] 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.[20] Diamond is commenced her deployment in the summer of 2012,[24] starting with celebrations to mark the Diamond Jubilee of Her Majesty Queen Elizabeth II.[25]

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 fired an Aster 30 off the coast of Scotland.[26]

On 4 September 2017, Diamond sailed for a 9-month deployment to the Middle East, initially scheduled to relieve HMS Monmouth,[27] 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.[28] 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.[29] 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.[30][31]


Ship's sponsor

Official affiliations


As part of her affiliation with Coventry, Diamond carries 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.[19]

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 HMS Sheffield.[33] The affiliation has now been transferred to the City of Coventry.[34][35]

Carrier Strike Group 12

Carrier Strike Group Twelve (CSG-12 or CARSTRKGRU 12) is one of four U.S. Navy carrier strike groups currently assigned to the United States Fleet Forces Command. Carrier strike groups gain and maintain sea control as well as project naval airpower ashore.USS Abraham Lincoln is the aircraft carrier assigned as the strike group's flagship. Units currently assigned to Carrier Strike Group Twelve included Carrier Air Wing One; the Ticonderoga-class cruisers Vicksburg and Normandy; and Destroyer Squadron 2.

Between 2006 and 2011, with USS Enterprise as its flagship, the group made four deployments to the U.S. Fifth Fleet in the Middle East. Strike group aircraft flew over 13,000 air combat missions in support of coalition ground forces in Iraq and Afghanistan, including 2006's Operation Medusa and Operation Mountain Fury in Iraq. The group's surface warships were also involved in several high-profile anti-piracy operations. The group participated in the multilateral exercises Anatolian Sun 2006, Reliant Mermaid 2007, BALTOPS 2008, and Malabar 2015; the bilateral exercise Inspired Union 2006; and the joint exercise Exercise Bold Alligator 2012.

The 2015 deployment was led by its new flagship, USS Theodore Roosevelt, which has since left the group and shifted homeport to Naval Base San Diego, California. Carrier Strike Group Twelve was the first U.S. Navy carrier strike group to deploy with a Naval Integrated Fire Control-Counter Air (NIFC-CA) capability that integrates all units via a data link to gain a more comprehensive overview of its operational battlespace. To augment this NIFC-CA capability, the strike group embarked the new E-2D airborne early warning (AEW) aircraft, making its first overseas deployment.

Carrier Strike Group 3

Carrier Strike Group 3 (CSG-3 or CARSTRKGRU 3) is a U.S. Navy carrier strike group. Carrier strike groups gain and maintain sea control as well as project naval airpower ashore. The aircraft carrier USS John C. Stennis (CVN-74) is the group's current flagship. Other units assigned include Carrier Air Wing Nine; the Ticonderoga-class cruisers USS Mobile Bay (CG-53) and USS Antietam (CG-54); and the ships of Destroyer Squadron 21.Between 2005 and 2013, the group made five deployments to the U.S. Fifth Fleet supporting U.S. ground forces in Iraq, and Afghanistan. On 18 December 2011, strike group aircraft flew the final carrier-based air mission over Iraq, effectively ending U.S. naval support for Operation New Dawn.

Guided missile destroyer

A guided-missile destroyer is a destroyer designed to launch guided missiles. Many are also equipped to carry out anti-submarine, anti-air, and anti-surface operations. The NATO standard designation for these vessels is DDG. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing or dropping it altogether. The U.S. Navy has adopted the classification DDG in the American hull classification system.

In addition to the guns, a guided-missile destroyer is usually equipped with two large missile magazines, usually in vertical-launch cells. Some guided-missile destroyers contain powerful radar systems, such as the United States’ Aegis Combat System, and may be adopted for use in an anti-missile or ballistic-missile defense role. This is especially true of navies that no longer operate cruisers, so other vessels must be adopted to fill in the gap.

HMS Coventry (D118)

HMS Coventry was a Type 42 (Sheffield-class) destroyer of the Royal Navy. Laid down by Cammell Laird and Company, Limited, at Birkenhead on 29 January 1973, she was launched on 21 June 1974 and accepted into service on 20 October 1978 at a cost of £37,900,000.

List of active Royal Navy ships

The Royal Navy is the principal naval warfare service branch of the British Armed Forces. As of November 2018, there are 74 commissioned ships in the Royal Navy. Of the commissioned vessels, twenty two are major surface combatants (six guided missile destroyers, thirteen frigates, two Landing Platform Docks and one aircraft carrier), and ten are nuclear-powered submarines (four ballistic missile submarines and six fleet submarines). In addition the Navy possesses two amphibious transport docks, thirteen mine countermeasures vessels, twenty-two patrol vessels, four survey vessels, one icebreaker and two historic warships, Victory and Bristol, although Bristol is not commissioned so is not in the ship count.

The Royal Navy operates three bases where commissioned ships are based; HMNB Portsmouth, HMNB Devonport and HMNB Clyde. In addition, a number of commissioned vessels belonging to the University Royal Naval Units (URNU) are stationed at various locations around the United Kingdom. The total displacement of the Royal Navy is approximately 407,000 tonnes (641,000 tonnes including the Royal Fleet Auxiliary and Royal Marines).

Besides the Royal Navy, the Royal Fleet Auxiliary and the Royal Marines operate their own flotillas of naval vessels which complement the assets of the Royal Navy, however they are not included in this list or the above figures. In addition, the naval training vessels Brecon and Cromer can be found based at the Royal Navy shore establishment HMS Raleigh and the Britannia Royal Naval College, respectively, along with a number of P1000's and Motor Whalers. As a supporting contingent of Her Majesty's Naval Service, the civilian Marine Services operate a large number of auxiliary ships (including coastal logistics, tugs and research vessels) in support of Royal Navy and Royal Fleet Auxiliary operations.All ships and submarines currently in commission with the Royal Navy were built in the United Kingdom, with the exceptions of icebreaker Protector which was built in Norway and survey vessel Magpie which was substantially built in Ireland. All vessels of the Royal Navy bear the ship prefix "HMS", for Her Majesty's Ship.

Missile defense systems by country

Missile defense systems are a type of missile defense intended to shield a country against incoming missiles, such as intercontinental ballistic missile (ICBMs) or other ballistic missiles. The United States, Russia, Taiwan, India, France, Israel and China have all developed missile defense systems.
