HNLMS Van Speijk (F802)

In the early 1960s, the Royal Netherlands Navy had an urgent requirement to replace its Van Amstel-class frigates, obsolete ex-American escorts built during the Second World War.

To meet this requirement, it chose to build a modified version of the British Leander-class frigate as its Van Speijk class, using broadly the same armament as the original design, but where possible, substituting Dutch electronics and radars.

Anti-aircraft defence was provided by two quadruple Sea Cat surface-to-air missile launchers on the hangar roof.

[4] The 4.5-inch gun was replaced by a single OTO Melara 76 mm and launchers for up to eight Harpoon anti-ship missiles fitted (although only two were normally carried).

The hangar and flight deck were enlarged, allowing a Westland Lynx helicopter to be carried, while the Limbo mortar was removed, with a pair of triple Mk 32 torpedo launchers providing close-in anti-submarine armament.

[4] Van Speijk herself was laid down at the Amsterdam shipyard of Nederlandsche Dok en Scheepsbouw Maatschappij on 1 October 1963 and was launched on 5 March 1965.

[12] On 11 February 1986, Indonesia and the Netherlands signed an agreement for transfer of two Van Speijk class with option on two more ships.

[1] The ship was transferred to Indonesia on 1 November 1986 and renamed KRI Slamet Riyadi on joining the Indonesian Navy, with the pennant number 352.

[15] In June 2020, the ship's hulk were planned to be sunk offshore on Karangasem Regency, Bali to be utilized as a diving attraction.
