Would the Royal Navy rebuild a modern class as deeply?

When might the Royal Navy rebuild a modern ship as extensively as an age-of-sail long refit?

The Type 23s have effectively undergone that kind of renewal, while planned Type 83, Type 26, and Type 31 construction makes another equally deep rebuild less necessary.

The Type 23 frigates have already undergone changes extensive enough to resemble the historical long-refit logic. Their hulls, machinery, and systems have altered markedly over their service lives. An equivalent future reconstruction is less likely for the Type 45 destroyers because the Type 83 and new frigate programmes provide a replacement path. Deep refit is therefore a fleet-planning decision as well as an engineering possibility. A navy must compare the value of extending an old hull with the timing and capability of ships already entering the programme.
