HMS Marlborough (F233)

HMS Illustrious was a light aircraft carrier of the Royal Navy and the second of three Invincible-class ships constructed in the late 1970s and early 1980s. She was the fifth warship and second aircraft carrier to bear the name Illustrious, and was affectionately known to her crew as "Lusty". In 1982, the conflict in the Falklands necessitated that Illustrious be completed and rushed south to join her sister ship HMS Invincible and the veteran carrier HMS Hermes. To this end, she was brought forward by three months for completion at Swan Hunter Shipyard, then commissioned on 20 June 1982 at sea en route to Portsmouth Dockyard to take on board extra stores and crew. She arrived in the Falklands to relieve Invincible on 28 August 1982 in a steam past. Returning to the United Kingdom, she was not formally commissioned into the fleet until 20 March 1983. After her South Atlantic deployment, she was deployed on Operation Southern Watch in Iraq, then Operation Deny Flight in Bosnia during the 1990s and Operation Palliser in Sierra Leone in 2000. An extensive re-fit during 2002 prevented her from involvement in the 2003 Iraq War, but she was repaired in time to assist British citizens trapped by the 2006 Lebanon War.

The Iraq War was a protracted armed conflict in Iraq from 2003 to 2011 that began with the invasion of Iraq by the United States-led coalition that overthrew the Iraqi government of Saddam Hussein. The conflict continued for much of the next decade as an insurgency emerged to oppose the coalition forces and the post-invasion Iraqi government. US troops were officially withdrawn in 2011. The United States became re-involved in 2014 at the head of a new coalition, and the insurgency and many dimensions of the armed conflict are ongoing. The invasion occurred as part of the George W. Bush administration's war on terror following the September 11 attacks, despite no connection between Iraq and the attacks.

HMCS Chicoutimi is a Victoria-class long-range hunter-killer (SSK) submarine of the Royal Canadian Navy, originally built and operated by the Royal Navy as HMS Upholder. Shortly after being handed over by the United Kingdom to Canada she was involved in a partial flooding incident which resulted in a fire at sea. The incident sparked a fierce debate over the value of the purchase of this group of second-hand vessels, as well as the handover inspection process. The subsequent investigation "determined the fire was caused by human, technical and operational factors, [and] the board cleared the commanding officer and crew of any blame." The submarine was repaired and entered Canadian service in 2015.

The current HMS Montrose is the eighth of the sixteen-ship Type 23 or Duke class of frigates, of the Royal Navy, named after the Duke of Montrose. She was laid down in November 1989 by Yarrow Shipbuilders on the Clyde, and was launched on 31 July 1992 by Edith Rifkind, wife of Malcolm Rifkind, Secretary of State for Defence. She was commissioned into service in June 1994.

RFA Argus is a ship of the Royal Fleet Auxiliary operated by the Ministry of Defence under the Blue Ensign. Italian-built, Argus was formerly the container ship MV Contender Bezant. The ship was requisitioned in 1982 for service in the Falklands War and purchased outright in 1984 for a four-year conversion to an Aviation Training Ship, replacing RFA Engadine. In 1991, during the Gulf War, she was fitted with an extensive and fully functional hospital to assume the additional role of Primary Casualty Receiving Ship. In 2009, the PCRS role became the ship's primary function. Argus is due to remain in service beyond 2030. In July 2022 it was reported that the future Littoral Strike Role would be assumed by Argus after a refit to convert her to this role.
