The £1 billion HMS Daring will become the most advanced warship in the world when it enters service with the Navy in 2009.The Type-45 destroyer, which is already exceeding targets, will now start taking on board Aster missiles, which are capable of knocking down a cricket ball-sized object travelling at three times the speed of sound.
The system is so powerful it can monitor all take-offs and landings from every major European airport within 200 miles of Portsmouth.
The ship can engage 12 air targets and will carry Harpoon anti-ship missiles and Tomahawk cruise missiles.
Officers claim that if it was stationed in the River Thames, its weapon system would be able to single-handedly destroy any incoming airborne attack on Greater London.
During four weeks of sea trials, Daring has achieved 31.5 knots - exceeding a target of 28 knots.
During final trials off the Western Isles yesterday Daring went through her paces smoothly, watched by the defence minister, Bob Ainsworth.
From a standing start she reached 29 knots in just 70 seconds and can come to a dead halt within 800 yards.
She can turn full circle within three ship lengths and has stealth technology that reduces the radar signature to that of a fishing boat.
"She's a beautiful ship to drive, like a souped-up Bentley with very smooth handling," said Lt-Cdr Phil Harper, the ship's navigator
It can also take 60 Special Forces troops, a large Chinook or Apache attack helicopters as well as Merlin anti-submarine helicopters.
The ship left American visitors to the yard on the Clyde "shaken and shocked", according to BAE Systems, its builders.
In the next 10 years, as many as eight T45s could be built, mainly to defend the two large aircraft carriers that were ordered last month.
