OVERVIEW: The Type 45 destroyer, also known as the D or Daring-class, is an advanced class of guided missile destroyers built for the United Kingdom's Royal Navy. The class is primarily designed for anti-aircraft and anti-missile warfare and is built around the PAAMS (Sea Viper) air-defence system utilizing the SAMPSON AESA and the S1850M long-range radars. The first three destroyers were assembled by BAE Systems Surface Fleet Solutions from partially prefabricated "blocks" built at different shipyards, the remaining three were built by BAE Systems Surface Ships. The first ship in the Daring class, HMS Daring, was launched on 1 February 2006 and commissioned on 23 July 2009.

The Type 45 destroyers were built to replace the Type 42 destroyers that had served during the Falklands War, with the last Type 42 being decommissioned in 2013. The National Audit Office reported that, during an "intensive attack", a single Type 45 could simultaneously track, engage and destroy more targets than five Type 42 destroyers operating together. After the launch of Daring on 1 February 2006 Admiral Sir Alan West, a former First Sea Lord, stated that it would be the Royal Navy's most capable destroyer ever, as well as the world's best air-defence ship. The reduction in the number to be procured from twelve, then to eight and eventually down to six (in 2008) was controversial.

DETAILS: The Type 45 destroyers are 152.4 m (500 ft) in length, with a beam of 21.2 m (70 ft) and a draught of 7.4 m. (24.3 ft) This makes them significantly larger than the Type 42 they replace, displacing approximately 8,500 tonnes compared to 5,200 tonnes of the Type 42. BAE Systems is the Design Authority for the Type 45, a role traditionally held by the UK Ministry of Defence. The design of the Type 45 brings new levels of radar signature reduction to the Royal Navy. Deck equipment and life rafts are concealed behind the ship's superstructure panels, producing a very "clean" superstructure somewhat similar to the French La Fayette-class frigates. The mast is also sparingly equipped externally. Speculation by the press suggests that this design gives the ship the radar signature of a small fishing boat.

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. The Royal Navy describes the destroyers' mission as being "to shield the Fleet from air attack".

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. The US Naval War College 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.

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. 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". 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. However, the Type 45 destroyer was designed to accommodate a total of 64-cells, while some reports suggest a total of 72-cells.
