BAP Aguirre (CH-84) was a De Zeven Provinciën-class cruiser in service with the Peruvian Navy.

Before being transferred to the Pacific Ocean, it underwent a major rebuild program by Rotterdamse Droogdok Maatschappij (RDM) at its shipyard in Rotterdam.

Modifications included the removal of its RIM-2 Terrier SAM system and the installation of a fixed hangar and a flight deck.

The upgrade was finished on October 31, 1977 and the ship was commissioned on February 24, 1978 at the Dutch naval base of Den Helder.

By the 1990s the ship systems were beginning to show their age, but lack of funds prevented any major upgrade.
