Type 45 destroyer
The Type 45 destroyer, also known as the D or Daring class, is a class of six guided-missile destroyers built for the United Kingdom's Royal Navy in the early 21st century. The class is primarily designed for anti-aircraft and anti-missile warfare and is built around the PAAMS (Sea Viper) air-defence system using the SAMPSON Active electronically scanned array (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 Maritime – Naval 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 (Sheffield-class) 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, then 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 (up to) eight, finally with only six confirmed (in 2008) was controversial.
In 2016, it was revealed that due to a design flaw on the Northrop Grumman intercooler attached to the Rolls-Royce WR-21 gas turbines, power availability was diminished considerably when functioning in the warm climate of the Persian Gulf, and it quickly became apparent that the class was not operating as originally envisioned. Therefore, a planned refit was scheduled from 2019 to 2021 to fully resolve the problems with the six ships in the class.
Under current plans, the Type 45 destroyer will be replaced by the Type 83 destroyer, the first of which is expected to enter service in the late 2030s.
The UK had sought to procure a new class of air-defence guided-missile destroyers in collaboration with seven other NATO nations under the NFR-90 project; the project collapsed due to varying requirements of the different countries involved. The UK then joined France and Italy in the Horizon-class frigate programme; however, differing national requirements, workshare arguments and delays led to the UK withdrawing on 26 April 1999 and starting its own national project. On 23 November 1999, Marconi Electronic Systems (MES), the defence arm of General Electric and in the process of merger with British Aerospace (BAe) since January, was confirmed as the prime contractor for the Type 45 project. Seven days later, MES and BAe completed the merger forming BAE Systems (BAE), making the latter the prime contractor.
The Type 45 project has been criticised for rising costs and delays, with the six ships costing £6.46 billion, an increase of £1.5 billion (29%) on the original budget. The first ship entered service in 2010, rather than 2007 as initially planned. In 2007, the Defence Select Committee expressed disappointment that the Ministry of Defence (MoD) and BAE had failed to control rising costs.
The Type 45 destroyers take advantage of Horizon development work and use the Sea Viper air-defence system and the SAMPSON radar. The ships were built by BAE Systems Maritime – Naval Ships, which subsequently became BVT Surface Fleet with the merger of the surface shipbuilding arms of BAE Systems and VT Group. These two companies had previously built the ships in collaboration. BAE's two Glasgow shipyards and single Portsmouth shipyard were responsible for different "blocks". BAE's Govan yard built Block A (stern to the edge of the helicopter hangar). The Scotstoun yard built Blocks B/C (a 2600-tonne section that contains the Rolls-Royce WR-21 gas turbines, starting with the helicopter hangar to the bridge section) and Block D (the bridge section itself). BAE's Portsmouth shipyard was responsible for Blocks E/F (bridge to the bow), funnels, and masts. For ships two to six, blocks A–D were assembled in the Ships Block and Outfit Hall of the Govan shipyard and taken fully outfitted to the Scotstoun berth. The masts and funnels were also fitted before launch.
For the first-of-class, Block A was assembled at Govan and moved to Scotstoun, where it was mated to Block B/C, which was already fitted with the WR-21 turbines and machinery. Block D, also assembled at Scotstoun, was fitted to these three blocks. The bow sections (E/F) were mated at HMNB Portsmouth and taken by barge to Scotstoun. These were the final blocks to be attached. At this point, the hull was launched into the Clyde and towed to the Scotstoun Dry Dock, where the masts and funnels were fitted (the masts were partially outfitted with equipment. For example, the mast for the S1850M radar is sent from Portsmouth to Thales Nederland to be fitted with radar equipment). Once this was complete, the remaining equipment was fitted: radar arrays, bow-mounted sonar, propellers, missile equipment, and the 4.5-inch gun.
