A delayed successor would require Type 45 destroyers to remain in service until replacement construction becomes available. Their hulls are described as designed for 30 years, so operating them toward 40 would require a substantial life extension. The discussion connects that burden to inadequate modernisation and maintenance of Britain's dry docks. Power improvements and Sea Ceptor additions are acknowledged as upgrades already under way, while the longer service-life problem remains. Replacement scheduling therefore has consequences for both ships and the facilities needed to keep them available.

Type 45 replacement delays, hull life, and dry docks
Keeping Type 45s beyond their intended hull life requires major work and enough suitable dry docks to carry it out.
