To ask the Secretary of State for Defence, what steps his Department is taking to improve the Royal Navy's anti-submarine warfare capability.

The Royal Navy continually reviews Anti-Submarine Warfare (ASW) capabilities. This will be enhanced by the introduction into service of the world-leading, cutting edge technology of the Type-26 ASW frigates and the continuing roll-out of the Astute class submarines. HMS ASTUTE, HMS AMBUSH and HMS ARTFUL are already in service, with HMS AUDACIOUS, HMS ANSON, HMS AGAMEMNON, and HMS AGINCOURT to follow.

The RAF P-8A Poseidon Maritime Patrol Aircraft will also play an intrinsic role as part of an integrated force to enhance maritime security and anti-submarine warfare. It will be fully integrated with other Royal Navy and NATO ASW assets. RAF Lossiemouth is preparing to welcome nine P-8A aircraft from 2020. They will be integrated into a £132 million strategic support facility with capacity to support Joint Expeditionary Force allies.
