Almirante Grau underwent a major modernization program between 1985 and 1988 during which she was fitted with new weapons and electronics. She was the last gun cruiser in service in any navy before being decommissioned on 26 September 2017.

In 2019, it was to be said that she would be preserved as a museum ship. However, it was later announced on 14 February 2022 that the ship would put up for sale with an asking price of 4,180,000 soles (1,112,520 USD).[citation needed]

Construction

De Ruyter was  laid down by the Royal Netherlands Navy on 5 September 1939 as the cruiser HNLMS De Zeven Provinciën at the Wilton-Fijenoord shipyard at Schiedam.[1][2] She and her sister-ship, later De Zeven Provinciën, were intended to replace the two Java-class cruisers in the Dutch East Indies.[2]

At the German invasion of the Netherlands in May 1940 little had been constructed. The Kriegsmarine intended to complete her as the training cruiser KH 1 but construction was slow and she was not launched until 24 December 1944, with the intent by then to use her as a blockship in the Nieuwe Waterweg, the approaches to Rotterdam.[1][2]

After the liberation of the Netherlands, the Navy completed De Zeven Provinciën with modifications.

She was commissioned as HNLMS De Ruyter (C801) on 18 November 1953, in the presence of Her Majesty Queen Juliana of the Netherlands. The first captain of the new cruiser was W. J. Kruys.[1][3]

Royal Netherlands Navy service

In Dutch service both ships participated in several NATO exercises, and were frequently used as flagships for different naval task forces.

Between 1962 and 1964, De Zeven Provinciën underwent a refit which included the removal of the two aft turrets and the installation of a RIM-2 Terrier SAM system, but lack of funds precluded the same modifications from being carried out in De Ruyter.[citation needed]

After two decades in service, she was decommissioned on 16 October 1972.[2]

Peruvian Navy service

The Peruvian Navy bought De Ruyter on 7 March 1973[1] as a counter to the acquisition of the Swedish cruiser Göta Lejon by the Chilean Navy.[citation needed] Commissioned on 23 May 1973 as Almirante Grau, in honor of the Peruvian Admiral Miguel Grau, the ship arrived at her new homeport of Callao on 11 July 1973.

She was designated fleet flagship in succession to another cruiser of the same name (the former HMS Newfoundland), which was renamed Capitán Quiñones.

Modernization

edit

From 1985 until 1988, she underwent a major modernization program by Amsterdam Naval Services (ANS) at its shipyard in Amsterdam, during which she was denominated Proyecto de Modernización 01 (Modernization Project 01) or PM-01.

Her role as flagship was assumed by her sistership Aguirre as Almirante Grau. Both ships regained their former names when the former De Ruyter returned to Callao on 15 February 1988.

The upgrade program carried out in the Netherlands included the following:

Further work was carried out by SIMA dockyards in Callao as follows:

The LW-08 radar was later replaced by an AN/SPS-6, the former being installed in the frigate BAP Carvajal (FM-51) in 2003.[4]

Decommissioning

edit

Almirante Grau was decommissioned on 26 September 2017. She was the last gun cruiser in service in any navy,[5] although its main armament was supplemented with Otomat anti-ship missiles.[5] She was replaced by the BAP Montero, now known as BAP Almirante Grau.

On 9 August 2019, the Peruvian Navy announced that she would be preserved as a museum ship in Lima,[6] though in February 2022, the ship was placed on sale.[7] In July 2022 it was reported[8] that she was to be scrapped.
