Formerly named HMS Ceylon (C-30), it was a British light cruiser that had served in World War II and the Korean War. As part of the Peruvian Navy, it participated in international exercises and relief operations for the populations affected by the 1970 Ancash earthquake. The ship was decommissioned on September 20, 1982, with the name Pontón Perú (UAI-113). Months earlier, the name "Coronel Bolognesi" had been assigned to a Friesland-class destroyer acquired from the Netherlands.
