Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what recent assessment he has made of the potential impact of climate change on the counter-sonar capabilities of the continuous at sea deterrent.

The Royal Navy continuously monitors the potential impacts of climate related risks to ensure its equipment remains suitable for future operating parameters.

Whilst for security reasons I cannot go into detail regarding operational capabilities, I can confirm that Defence is committed to making preparations for the more extreme conditions that climate change may bring, in order to maintain operational advantage.
