Type 45 has more than 20,000 power and data cables, stretching some 620kms. Laid end-to-end they would stretch from Glasgow to Bristol.
The ship will be 44 metres from keel to the top of the Sampson radar dome, as high as the Nelson Monument at Glasgow Green.
The ships are built in modular sections, with first steel cut on Dauntless on 26th August 2004. She is due to enter service in 2010, following the first of class Daring in 2009. The bow and mast sections are made by VT Shipbuilding in Portsmouth and transported over 500 miles to Glasgow by sea-going barge.
The Type 45 flight deck is large enough to park 20 London buses. More usefully, it is large enough to land a Chinook helicopter, although the ships will normally carry Merlin helicopters.
External communications include Internet and Video Conferencing while deployed anywhere in the world. Comprehensive internal communications including full "wirefree" communications for tasks such as fire-fighting.
Propulsion
The Type 45 is the first front-line warship to use all-electric propulsion. What are the advantages?
- More efficient because you can run the whole ship (propulsion, weapons and hotel) off a single power plant at a reasonable speed (say, 18 knots).
- More flexible through-life because there is no gearbox (which is a notorious source of mechanical problems and thus lay-ups)
Fewer Installed Prime Movers
Fewer Running Prime Movers
Simpler System (No CPP or Gearbox)
Fuel efficient gas turbines
Reduced Through Life Cost
Range
A Type 45 has a range of around 7000 nautical miles – that’s New York and back without refuelling. Compare this to a Type 42 with a range of around 4000 nautical miles.
Power
The WR21 gas turbines, with their state-of-the-art recuperators are about the most efficient out there. Each gas turbine produces about 24 MegaWatts.
Stealth
The design incorporates stealth technology to reduce the chances of it being identified – this includes the cooling of exhaust gases to reduce the infra-red signature and avoiding the use of right angles – this helps to reduce the radar signature.
Materials
Although the Type 45 is one of the most advanced warships in the world it uses many standard materials from commercial shipbuilding, this allows the maximum possible investment in the defensive systems.
Radar
The long range radar has a range of hundreds of kilometres. The multi-function radar is much lighter than previously used – this means it can be positioned much higher on the mast which increases its range. One of its main functions is to detect sea-skimming missiles and it is one of the most advanced in the world.
PAAMS
The principle anti-missile system can deal with multiple targets simultaneously and is the most advanced system of its kind in the world. It can identify and deal with more threats simultaneously and deploys missiles more quickly and effectively.
Aster missiles
The missiles are 20 times more maneuverable than a Formula 1 car (pulling over 60G)
Living on board
The Type 45 offers each crewmember an average of 37% more space than on previous ships with the amount of space now equivalent to the passenger space onboard commercial ferries.
Type 45 is also the first UK warship with a dedicated gym onboard.
- 39% increase in crew space
- Officers in Single Cabins
- YOs in 2 Berth Cabins
- SRs in Single/2Berth Cabins
- JRs in 6 Berth Cabins
- Separate Fitness Centre
