Britain commits £1.5 billion to Atlantic Bastion to counter Russian submarines and protect critical undersea cables and pipelines

Britain will add £1.5 billion over four years to Atlantic Bastion, a Royal Navy programme intended to detect Russian submarine activity and protect undersea cables, pipelines and other critical infrastructure. The concept links crewed warships and maritime patrol aircraft with autonomous surface and underwater vessels through shared digital networks. Funding is aimed at improving persistent surveillance and accelerating the passage from detection to operational response across the North Atlantic. The announcement establishes a funded capability direction, although it does not specify platform quantities, contractors or a detailed deployment schedule for the autonomous elements.
