How many cruise missiles might a Resolution-class SSGN conversion carry?
Short answerAbout 36 to 48 contemporary missiles, although the lack of a suitable British weapon around 1970 would be the more serious constraint.
NotesThe scenario converts the cancelled fifth Resolution-class submarine, Ramillies, into a guided-missile boat rather than a ballistic-missile submarine. If laid down around 1966, it might have entered service near 1970 and preserved some specialist construction capacity. The estimate is roughly thirty-six to forty-eight weapons because contemporary cruise missiles were larger than later Tomahawks. Capacity is therefore only part of the problem: Britain did not possess an obvious suitable missile for the boat at that date. The numerical estimate should be read as a design-order approximation tied to period weapon dimensions, not a detailed conversion study.
