To ask the Secretary of State for Defence, on how many occasions a Royal Navy submarine was deployed to the Arctic region in each of the last six years.
To ask the Secretary of State for Defence, what assessment he has made of the capacity of the Royal Navy's Astute-class submarines for under-ice operations.
The Astute class submarines are the largest, most advanced and most powerful attack submarines ever operated by the Royal Navy, combining world-leading sensors, design and weaponry in a versatile vessel. The Royal Navy maintains world-wide deployability with its submarines, this includes under-ice capability.
We do not discuss the detail of such submarine operations, as this would, or would be likely to, prejudice the capability, effectiveness or security of the Armed Forces.
