HMS Anson's role

HMS Anson represents the cutting edge of the United Kingdom’s military capabilities. She is armed with Tomahawk land attack missiles and Spearfish heavyweight torpedoes, befitting her role as an attack submarine.

The nuclear reactor onboard HMS Anson does not need to be refuelled during her 25-year service period, while the ability to purify her own water and air means that her range is limited only by the amount of food onboard. As a result, she is capable of circumnavigating the globe without resurfacing.
