Notes:
The Huascar is maintained by the Chilean Navy as a historical vessel and memorializes the heroes, both Chilean and Peruvian, who fought and died upon her decks. It is forbidden by Chilean law to sell, scrap, or cosmetically alter the ship. Although it has a caretaker crew provided by Naval Academy cadets, the ship is permanently anchored in Talcahuano and is no longer regarded as a fighting vessel.
