Why Vanguard replacement cannot simply be accelerated

Should Britain accelerate replacement of the Vanguard-class submarines after recent reported problems?

The replacement is already under way, and moving faster would require substantially more submarine-building infrastructure.

Replacement of the Vanguard class is already proceeding on its planned schedule. Accelerating it would require additional submarine-construction infrastructure rather than a simple change of priority. Reported mishaps are not necessarily unprecedented, and recurring engineering problems are managed through redundancy and established procedures.
