Boeing P-8 and Type 26 Frigates: North Atlantic Ocean

Question

To ask the Secretary of State for Defence, how many (a) Type 26 frigates and (b) P-8 Poseidon aircraft will be assigned to Atlantic Bastion and when will they begin operations as part of AB.

Answer

Atlantic Bastion (AB) is Defence’s plan to secure the North Atlantic for the UK and NATO against the persistent and growing underwater threat. AB is not an operation; it is a plan to transition to a hybrid Navy, combining both crewed and uncrewed underwater systems. The details of this ambition are subject to the Defence Investment Plan.
