The Hr. Ms. De Ruyter (C -801 ) (full Dutch name:. Mr. Ms. Kruiser De Ruyter ) was a cruiser De Zeven - Provinciën - class of the Royal Netherlands Navy. It was put into service in 1953 and was the ninth ship, which was named after the Admiral Michiel de Ruyter. This cruiser was, along with its sister ship De Zeven Provinciën, the largest built in the Netherlands warship. After her career at the Dutch navy in 1972 it was sold to Peru, where it was placed in 1973 as BAP Almirante Grau ( CLM -81 ) back into service and still stands in the service of the Peruvian Navy.

History

Netherlands Navy

The cruiser was laid on September 5, 1939 in Wilton Fijenoord in Schiedam as De Zeven Provinciën under the hull number 670 at Kiel. Together with her sister ship Eendracht it was intended as a replacement for the obsolete cruisers of the Java class. After the German occupation of the Netherlands, the construction was continued slowly but later suppressed by the occupying power. On 24 December 1944, the shell was lowered into the water to serve as a waterway lock. However, this plan could not be carried out and the unfinished hull remained lying in the harbor of Schiedam.

After the war and the recovery of the shell completion began after highly modified plans. Especially the armament had to be completely re-planned. The originally planned, ordered in Sweden turrets were no longer available, as the Swedish Navy had already been used for one's own Tre Kronor - class. The ship also had to be renamed because the sister ship, the former Eendracht, as De Zeven Provinciën was baptized in Rotterdam on August 22, 1950 by Queen Juliana. So ( the largest unit of the Dutch Navy at the time) was the name of De Ruyter chosen on the basis of the 1942 decline in the Java Sea light cruiser.

However, the De Ruyter could be put into service until 18 November 1953. With the 926 -strong crew and Queen Juliana and her husband Prince Bernhard on board the ship in 1955 undertook a journey to the Netherlands Antilles. While the sister ship De Zeven Provinciën was modernized in the early sixties and equipped with missiles starters, this conversion was omitted in De Ruyter lack of money.

Peruvian Navy

After the decommissioning at the Koninklijke Marine in 1972 the Netherlands sold the ship to Peru, where it was placed on May 23, 1973 as Almirante Grau returned to service. It is still in use today and the last active warship with heavy artillery as the main armament. In the years 1985-1988, during modernization work was carried out on the ship in Amsterdam, the name was changed to Proyecto de Modernización 01 or PM -01. During this time, the sister ship Aguirre was listed as Almirante Grau.
