The question

To ask the Secretary of State for Defence, what progress has he made in delivering the cobalt autonomy stack for the Royal Navy.

Answered by Luke Pollard

Under Atlantic Bastion, announced in the Strategic Defence Review, the Royal Navy will be exploiting new technologies through a portfolio of crewed and uncrewed vehicles, sensors and nodes. The Cobalt Autonomy Stack acts as an autonomy and mission control layer, sitting above a fleet of mixed assets and connecting their sensors and effectors.

The Atlantic Bastion capability options submitted for consideration in the Defence Investment Plan include a blend of uncrewed systems, underwater payloads, options to increase lethality, and improvements to crewed platforms which are consistent with the transition to a Hybrid Navy.
