A flexible force
Attack submarines typically deploy for around two months at a time. Their combination of world-leading sonar and state-of-the-art weaponry means they can be extremely versatile, from silently patrolling international waters to hunting down enemy targets.
These missiles have a 1,000+ mile range, can change course in mid-air and return images of the battlefield.
Our new Astute-class submarines are about the length of a football pitch and all have a gym on board.
