Royal Navy submarine combat records

The Royal Navy receives credit for two rare submarine combat records, although the exchange leaves the conditions of one claim unspecified.

Question

Which navy has achieved a confirmed submarine-against-submarine sinking?

Short answer

The Royal Navy, although the exchange does not specify what makes the submarine-against-submarine sinking unique. The nuclear-powered submarine claim is explicitly tentative.

Notes

The question credits the Royal Navy with a unique confirmed submarine-against-submarine sinking, and the reply accepts that claim. Neither submarine is named, and the conditions that would make the sinking unique are not specified. A separate, explicitly tentative claim gives the Royal Navy the only ship sinking by a nuclear-powered submarine. The brief answer supplies no further details for either action.
