The question

To ask the Secretary of State for Defence, what progress his Department has made on securing new capability by the Royal Navy’s Anti-Submarine Warfare Spearhead programme.

Answered by Luke Pollard

The Anti-Submarine Warfare (ASW) Spearhead Programme has focussed on accelerating the Navy’s understanding of advanced capabilities. Key areas progressed include maritime autonomy, machine learning and artificial intelligence, to supplement existing crewed platforms.

Investment in the Anti-Submarine Warfare Sonar 2087 system has led to improvements to Type 23 capabilities. These improvements will also be pulled through to the Type 26 programme. ASW Spearhead has developed new capability for the Merlin Mk2 Maritime Patrol Helicopter, resulting in a significant increase in sensor coverage.
