Operational history

Duncan‍ '​s construction began at the BAE Systems Naval Ships (now part of BAE Systems Surface Ships) yards at Govan and Scotstoun on the River Clyde in 2006. She was launched from Govan on 11 October 2010,[10] on the 213th anniversary of the Battle of Camperdown).[11] HMS Duncan sailed from Scotstoun shipyard, Glasgow on 31 August 2012 to commence sea trials.[12] Duncan, the sixth and last type 45 destroyer, was commissioned on 26 September 2013.[1] She entered service on 30 December 2013, 4 months ahead of schedule, after a period of trials and training.[13]

On 2 March 2015, Duncan left HMNB Portsmouth on her maiden deployment to the Mediterranean and Middle East.[14] On 7 July 2015, the Royal Navy's Type 45 Destroyer HMS Duncan paired with the U.S. Navy Carrier Strike Group Twelve in strikes against Daesh.[15]


Advanced air-defence

The Type 45 destroyers are primarily designed for anti-air warfare with the capability to defend against sophisticated targets such as fighter aircraft, drones as well as highly maneuverable sea skimming anti-ship missiles travelling at supersonic speeds.[16] The Royal Navy describes the destroyers' mission as being "to shield the Fleet from air attack".[17] The Type 45 destroyer is equipped with the sophisticated Sea Viper (PAAMS) air-defence system utilizing the SAMPSON active electronically scanned array multi-function radar and the S1850M long-range radar. The PAAMS system is able to track over 2,000 targets and simultaneously control and coordinate multiple missiles in the air at once, allowing a large number of tracks to be intercepted and destroyed at any given time. This makes the PAAMS system particularly difficult to swamp during a saturation attack, even against supersonic targets.[18] The USNWC has suggested that the SAMPSON radar is capable of tracking 1,000 objects the size of a cricket ball travelling at three times the speed of sound (Mach 3), emphasising the system's capabilities against high performance stealth targets.[16] A core component of the PAAMS air-defence system is the Aster missile, composing of the Aster 15 and Aster 30. MBDA describe Aster as a "hit-to-kill" anti-missile missile capable of intercepting all types of high performance air threats at a maximum range of 120 km.[19] 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".[19] Presently the Daring-class destroyers are equipped with a 48-cell A50 Sylver Vertical Launching System allowing for a mix of up-to 48 Aster 15 and 30 missiles.

Weapons, countermeasures, capabilities and sensors

In 2014, the Royal Navy website stated that Duncan would be the first Type 45 destroyer to be armed with the Harpoon anti-ship missile system.[20]

On 2 March 2015, Duncan left Portsmouth armed with Harpoon anti-ship missiles.[14]
