The brief use of Cromwell as a Royal Navy ship name

Was there ever a Royal Navy ship named Cromwell?

Yes. A C-class destroyer briefly carried the name in 1946 before transfer to Norway as Bergen.

A C-class destroyer carried the name Cromwell in 1946 before becoming Bergen in Norwegian service. The reference gives a June renaming followed by sale in July. The short interval suggests that the rename was connected with the transfer. This qualifies the initial assumption that Cromwell's association with regicide had prevented any Royal Navy use of the name.
