Question

How long would Britain need to build twelve Resolution SSBNs and twelve Resolution SSGNs?

Short answer

About twelve to thirteen years using two yards that each build two boats concurrently.

Notes

Using historical build times, Vickers and Cammell Laird could each construct two boats simultaneously. With overlapping work, output could reach roughly four boats every two years. That yields about twelve years in ideal arithmetic and closer to thirteen in practice.
