Guaranteeing sovereignty at sea
With the multiplication of regional tensions, actors and threats, the control of maritime spaces is now, more than ever, a key foundation of power and sovereignty for nations with submarines playing a critical role.
Their mission: provide deterrence, protect economic zones, monitor wide areas, collect intelligence and make a difference in inter-allied operations. Among the most complex systems ever built, submarines are the very cornerstones of strategic oceanic forces.
