HMS Swiftsure was due to begin another refit in 1992 but was instead decommissioned to save money. Public explanations referred to pressure-hull damage found during trials, while other accounts pointed to cracks associated with the reactor. The reactor was removed in June 1992, but the available account does not establish which technical explanation was decisive. A simpler possibility is that the Navy did not want to fund major work on an aging submarine. Safety, engineering condition, and affordability may all have shaped her retirement.
