HNLMS Van Galen (F803) was a Van Speijk-class frigate of the Royal Netherlands Navy, commissioned in 1967 and decommissioned in 1987. Built at the KM de Schelde shipyard in Vlissingen, her keel was laid on July 25, 1963, and she was launched on June 19, 1965. The vessel measured 113.4 meters in overall length, with a beam of 12.5 meters and a draught of 5.8 meters. Displacing approximately 2,200 long tons at standard load and up to 2,850 long tons at full load, she was powered by two Babcock & Wilcox boilers driving twin Werkspoor-English Electric turbines rated at 30,000 shp, achieving a top speed of 28.5 knots. Her armament as built included a twin 4.5-inch Mark 6 gun mount positioned forward, complemented by two quadruple Sea Cat missile launchers on the hangar roof for anti-aircraft defense. She was equipped with a Limbo anti-submarine mortar aft and had a hangar and helicopter deck capable of operating a Westland Wasp helicopter for extended anti-submarine and surface operations. Her radar suite featured a Signaal LW-03 long-range air search radar and a DA02 medium-range radar, with fire control radars for her missile and gun systems. Sonar systems included Type 170B attack sonar and Type 162 bottom search sonar, with a crew complement of 251. During the 1970s, Van Galen underwent a significant modernization at Den Helder, replacing her 4.5-inch gun with an OTO Melara 76 mm gun, installing up to eight Harpoon anti-ship missiles (though only two were typically carried), and enlarging her hangar and flight deck to operate a Westland Lynx helicopter. Her sonar and radar systems were upgraded to newer models, including the DA03 radar and an EDO CWE-610 sonar. Van Galen’s service included a notable 1970 Far East deployment and participation in a 1976 visit to New York for the city’s bicentennial celebration. In 1987, she was sold to Indonesia, renamed KRI Yos Sudarso (353), and saw active service in the Indonesian Navy, including intercepting a Portuguese ship in East Timor in 1992. The vessel was later re-engined with Caterpillar diesel engines and rearmed with Chinese C-802 missiles, reflecting her continued operational relevance until her eventual retirement.
