Recommendation 21

The Astute class represent arguably the best attack submarine in the world, but they cannot effectively deter anyone until they are actually in service; therefore we cannot afford any further delay in the delivery of the remaining Astute boats. We are concerned by reports that submarine availability is weak, and not reassured by learning that the US and Australian submarine fleets are no better. Reported issues with the availability of the Vanguard class submarines that deliver the nuclear deterrent mean that the Dreadnought successor programme must be brought in on schedule, as further life extensions cannot be relied upon to fill in any gaps. The Ministry of Defence should set out in its response appropriate arrangements it will use to ensure that we are briefed on submarine availability once a year, with due regard to both security and the importance of scrutiny to ensure effective delivery.
