The Royal Navy's newest Type 45 destroyer, 'HMS Defender', sails to her new home at Naval Base Portsmouth. The ship's arrival at her new base brings Defender a step closer to her first deployment. She will now undergo sea trials before being declared ready for operations in 2013. Armed with the world-leading Sea Viper missile defence system, the 7,500-tonne vessel is able to defend against multiple attacks from even the most sophisticated anti-ship missiles, approaching from any direction and at supersonic speeds.
