Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what steps he is taking to ensure that the Royal Air Force and Royal Navy have sufficient submarine detection capabilities.

The UK Armed Forces have an internationally highly regarded and multi-layered submarine detection capability, primarily delivered through a combination of surface ships, submarines and anti-submarine helicopters, alongside close co-ordination and co-operation with our allies. As the global environment and threat capabilities constantly evolve, we continue to develop new detection capabilities in order to maintain our operational advantage.

These capabilities are subject to regular audit and analysis. The Strategic Defence and Security Review 2015 will afford us the opportunity to review the full spectrum of submarine detection capability, including fixed wing Maritime Patrol Aircraft utility.

I am withholding further details of our capabilities and programmes as disclosure would, or would be likely to, prejudice the capability, effectiveness or security of the Armed Forces.
