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.
[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] Tjerk Hiddes was laid down at the Amsterdam shipyard of Nederlandsche Dok en Scheepsbouw Maatschappij on 1 June 1964 and was launched on 17 December 1965.
[5][9] In 1969 Tjerk Hiddes participated in the NATO exercises Razor Sharp and Peace Keeper and also served with STANAVFORLANT.
[1] The ship was transferred to Indonesia on 31 October 1986 and renamed KRI Ahmad Yani on joining the Indonesian Navy, with the pennant number 351.
