The survival claim depends on condition rather than the mere existence of a hull. HMCS Stormont became the yacht Christina O, preserving material while radically changing the ship's purpose and appearance. The former HMCS Hallowell continued in Sri Lankan service as Gajabahu, while the former HMS Fal became Myanmar's museum ship Mayu. The current condition and use of those vessels remain uncertain in this account. None presents the complete River-class frigate form still visible in Diamantina, which is why her survival is historically distinctive.

Why Diamantina is the last River-class frigate in original form
Other River-class hulls survived as a yacht, training vessel, or museum ship, but alterations and uncertain condition leave Diamantina as the last preserved example in full frigate form.
