The question

To ask the Secretary of State for Defence, what steps he has taken to improve the sonar capabilities of the Royal Navy surface fleet.

Answered by Luke Pollard

The Defence Innovation Anti-Submarine Warfare (ASW) Spearhead Programme has focussed on accelerating the Navy's understanding of advanced capabilities. Key areas progressed include sensor optimisation, machine learning and artificial intelligence, to improve the sonar capabilities within the surface fleet.

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.
