HNLMS Van Speijk (F802) (Dutch: Hr.Ms. Van Speijk) was a frigate of the Van Speijk class. The ship was in service with the Royal Netherlands Navy from 1967 to 1986. The ship's radio call sign was "PAVA".[2] She was sold to the Indonesian Navy where the ship was renamed KRI Slamet Riyadi (352). The ship was decommissioned in 2019.
In the early 1960s, the Royal Netherlands Navy had an urgent requirement to replace its Van Amstel-classfrigates, 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-classfrigate as its Van Speijk class, using broadly the same armament as the original design, but where possible, substituting Dutch electronics and radars.[3]
A twin 4.5-inch (113 mm) Mark 6 gun mount was fitted forward. Anti-aircraft defence was provided by two quadruple Sea Catsurface-to-air missile launchers on the hangar roof. A Limbo anti-submarine mortar was fitted aft to provide a short-range anti-submarine capability, while a hangar and helicopter deck allowed a single Westland Wasp helicopter to be operated, for longer range anti-submarine and anti-surface operations.[4][5]
As built, Van Speijk was fitted with a Signaal LW-03 long range air search radar on the ship's mainmast, with a DA02 medium range air/surface surveillance radar carried on the ship's foremast. M44 and M45 fire control radars were provided for the Seacat missiles and ships guns respectively.[4][6] The ship had a sonar suite of Type 170B attack sonar and Type 162 bottom search sonar.[4] The ship had a crew of 251, later reduced to 180.[4][1]
Modifications
Closer view of the bridge of the upgraded ship; most notable is the round profile single-barrel turret for the OTO Melara 76 mm cannon which replaced the dual 4.5-inch guns housed in a rectangular turret.
All six Van Speijks were modernised in the 1970s, using many of the systems used by the new Kortenaer-classfrigates.[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. A Signaal DA03 radar replaced the DA02 radar and an American EDO Corporation CWE-610 sonar replaced the original British sonar.[4][7]Van Speijk was modernised at the Den Helder naval dockyard between 24 December 1976 and 3 January 1979.[8][7]
The ship received a mid-life modernization in Den Helder, starting on 24 December 1976 and lasting till 3 January 1979.[8]
8 February 1982 the ship together with the frigates Tromp, Callenburgh, Piet Hein, the destroyer Overijssel and the replenishment ship Zuiderkruis departed from Den Helder for a trip to the USA to show the flag and for 200 years diplomatic relations. The ships returned to Den Helder on 19 May 1982.[10]
In 1986, she was put up for sale along with sister ships Tjerk Hiddes, Van Galen and Van Nes.[7] The four ships then were purchased by Indonesia. Van Speijk was decommissioned in early 1986 and transferred to the Indonesian Navy on 1 November 1986.[12]
Indonesian service history
KRI Slamet Riyadi in Laut Strait, 12 December 2014
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.[12][1]
By 2002, the ships Seacat missiles were inoperable and it was reported that propulsion problems were badly effecting the availability of the ships of this class.[1]Slamet Riyadi was then modernized by PT Tesco Indomaritim, which was completed in 2008.[1] The ship's Seacat launchers were replaced by two Simbad twin launchers for Mistral anti-aircraft missiles, and she was re-engined with two 10.9 megawatts (14,600shp)Caterpillar 3616 diesel engines.[1] As the Indonesian Navy retired Harpoon missile from its stockpiles, Slamet Riyadi was rearmed with Chinese C-802 missiles.[13]
Slamet Riyadi was decommissioned on 16 August 2019, along with five other ships of the Indonesian Navy.[14]

HMS Amazon was the first Type 21 frigate of the Royal Navy. Her keel was laid down at the Vosper Thornycroft shipyard in Southampton, England. The ship suffered a fire in the Far East in 1977, drawing attention to the risk of building warships with aluminium superstructure.
The Leander-class, or Type 12I (Improved) frigates, comprising twenty-six vessels, was among the most numerous and long-lived classes of frigate in the Royal Navy's modern history. The class was built in three batches between 1959 and 1973. It had an unusually high public profile, due to the popular BBC television drama series Warship. The Leander silhouette became synonymous with the Royal Navy through the 1960s until the 1980s.
HMS Danae was a Leander-class frigate of the Royal Navy. She was, like the rest of the class, named after a figure of mythology. Danae was built by Devonport Dockyard. She was launched on 31 October 1965 and commissioned on 10 October 1967.
HMS Gurkha (F122) was a Tribal-class frigate of the Royal Navy. She was named after an ethnic group located in Nepal, and who continue to serve in the British Army. She was sold to the Indonesian Navy in 1984 and renamed KRI Wilhelmus Zakarias Yohannes (332).
HMS Zulu (F124) was a Tribal-class frigate of the Royal Navy in service from 1964 to 1984. She was the third ship bearing the name of HMS Zulu, having been named after an ethnic group located primarily in KwaZulu-Natal Province, South Africa. Zulu was built by Alexander Stephen and Sons, of Govan. She was launched on 3 July 1962 and commissioned on 17 April 1964.
The Almirante Padilla-class frigates is a series of frigates operated by the Colombian Navy. The designation of this class is Type FS 1500 and there are four ships in service. The ships were built by Howaldtswerke-Deutsche Werft (HDW) at Kiel, West Germany in the 1980s, with the first vessel commissioning in 1983 and the last in 1984. The frigates have undergone significant modification over their careers with the 2012 Orion Program Upgrade significantly modernising the vessels. Two similar ships operate as the Kasturi-class corvettes in the Royal Malaysian Navy.
The Nilgiri-class frigates were updated versions of the Leander class, designed and built for the Indian Navy by Mazagon Dock Limited in Mumbai. Six ships were built between 1972–81. Vessels of the class formed the 14th Frigate Squadron. The lead ship INS Nilgiri was the first major warship to be built in India and was built in collaboration with Yarrow Shipbuilders of the United Kingdom.
The Kortenaer class was a class of anti-submarine frigates of the Royal Netherlands Navy. Like other frigate types of the 1970s and 1980s, they featured a COGOG propulsion system with separate cruise and sprint gas turbines. Ten were built by De Schelde in Vlissingen and two by Wilton-Fijenoord in Schiedam between 1978 and 1982. Only ten served with the Royal Netherlands Navy: two were sold to Greece's Navy while still under construction and replaced by two Jacob van Heemskerck-class frigates which were an air defence variant of the Kortenaer class. The Greek frigates were renamed the Elli class. After service with the Dutch ended, eight of the frigates were sold to Greece in 1992 and the remaining two to the United Arab Emirates. Three of the ships have since been retired from active military service with one converted into the superyacht Yas.
The Wielingen class is a class of four multi-functional frigates constructed for and operated by the Belgian Naval Component. In service from 1976 to 2008 with the Belgians, three of the class were sold to Bulgaria for service with the Bulgarian Navy beginning in 2004. The fourth, Westhinder, ran aground in 1988, was decommissioned in 1993 and was scrapped.
The Jacob van Heemskerck-class frigate was a class of frigates of the Royal Netherlands Navy. They were designed to be an air defence version of the Kortenaer class. The helicopter was replaced by a Standard medium range surface-to-air missile (SAM) system and associated radars. Two ships were built for the Royal Netherlands Navy. In 2005 they were sold to the Chilean Navy.
The Van Speijk-class frigates were built for the Royal Netherlands Navy in the 1960s. They were versions of the British Leander-class frigates with Dutch radars. The British design was chosen in order to enable rapid construction in order to replace elderly destroyer escorts and take up part of the NATO patrol duties of the decommissioned anti-submarine warfare carrier Karel Doorman. The ships were modernised in the late 1970s. All six ships were sold to the Indonesian Navy in 1986–1989 and five are still in service as the Ahmad Yani-class frigates.
HNLMS Van Kinsbergen (F809) was a frigate of the Kortenaer class. The ship was in service with the Royal Netherlands Navy from 1980 to 1995. The frigate was named after Dutch naval hero Jan Hendrik van Kinsbergen.
The Admiral Pereira da Silva class of frigates, also known as Admiral-class frigates, were in the service of the Portuguese Navy between 1966 and 1985. The class was based on the Dealey-class destroyer escort of the United States Navy. The three ships of the class were built in Portugal, at the Lisnave shipyards and the shipyards of Viana do Castelo. The construction of the ships was part of the effort of Portugal to expand its fleet in the face of unrest in the empire and was financed by the United States via the Mutual Defense Assistance Program. Financial problems prevented them from ever being modernised and they were deleted in 1989.
HNLMS Overijssel (D815) was a destroyer of the Friesland class. The ship was in service with the Royal Netherlands Navy from 1957 to 1982. The destroyer was named after the Dutch province of Overijssel and was the twelfth ship with this name. In 1982 the ship was taken out of service and sold to Peru where it was renamed Coronel Bolognesi.
