HMS Ambush's role

Armed with Tomahawk land attack missiles and Spearfish heavyweight torpedoes, HMS Ambush represents the cutting edge of the United Kingdom’s military power. As an attack submarine, her mission is neatly summed up by her motto: Hide and Seek.

The nuclear reactor onboard HMS Ambush will never need to be refuelled during her 25-year service period, while the ability to purify her own water and air mean that her range is limited only by the amount of food onboard. As a result, HMS Ambush is capable of circumnavigating the globe without resurfacing.
