Every Christmas Autocar road tests a vehicle with a difference, and few have been more impressive than HMS Diamond, a Type 45 destroyer.
HMS Diamond is the third of six Type 45 Daring Class destroyers ordered by the Ministry of Defence and being delivered to the Royal Navy.
To find out just how good the ship is we climbed on board during sea trials, toured the ship, experienced her capabilities and even took a turn at the wheel.
Below are some of the highlights of the test:
Design and engineering
HMS Diamond's radar and missile systems are dubbed Sea Viper, a system so advanced that if she was moored next to HMS Belfast in London, it could monitor all flights out of Gatwick, Heathrow, Paris Charles de Gaulle, Amsterdam Schipol and Birmingham airports and assess each one's threat level within a second.
If it did detect a threat, it could fire a missile that reaches Mach 3 within two seconds, pulls 60g and has the ability to intercept a cricket ball-sized object, also travelling at three times the speed of sound.
