HMS Anson's role

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

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