KRIUsman Harun (359) is aBung Tomo-class corvette in service with theIndonesian Navy. She was originally built for theRoyal Brunei Navy and launched as KDBBendahara Sakam in 2001.[1]Usman Harun is the third ship of theBung Tomo class.
TheBung Tomo-class corvettes are three vessels built byBAE Systems Marine (nowBAE Systems Maritime – Naval Ships). The contract was awarded toGEC-Marconi in 1995 and the ships, a variant of the F2000 design, werelaunched in January 2001, June 2001 and June 2002 at the then BAE Systems Marine yard atScotstoun,Glasgow. The customer refused to accept the vessels and the contract dispute became the subject ofarbitration. When the dispute was settled in favour of BAE Systems, the vessels were handed over to Royal Brunei Technical Services in June 2007.[2]
In 2007, Brunei contracted the GermanLürssen shipyard to find a new customer for the three ships. In 2013, Indonesia bought the vessels for£380 million or around half of the original unit cost.[1]
The ships were originally armed withMBDA Exocet Block II anti-ship missiles andMBDA Seawolf air-defence missiles. The main gun is an OTO Melara 76 mm; the ship also carries two torpedo tubes, two 30 mm remote weapon stations and has a landing spot for a helicopter. As of 2018, the MBDA Seawolf missile was out of service there was plans to replace it with theVL Mica.[3]
The ship was launched as KDBBendahara Sakam on 23 June 2001, but never commissioned into theRoyal Brunei Navy. Her original namesake is the Bruneian folk heroBendahara Sakam, who took part in theCastilian War in the mid- to late 16th century.[citation needed] She was subsequently sold andcommissioned into theIndonesian Navy as KRIUsman Harun on 18 July 2014. Her hull number 29 was changed to 359.[4][5]
TheSingapore government protested against the naming of the ship, as its namesakesUsman Haji Muhammad Ali andHarun Said had committed the 1965MacDonald House bombing during theIndonesia-Malaysia confrontation, resulting in three deaths and thirty-three casualties. As theywore civilian clothes and targeted civilians, they were tried for murder and executed. The ship was subsequently banned from entering Singapore ports and sea bases, with theSingapore Armed Forces declining to partake in exercises involving the ship.[6][7][8]
In early January 2015, KRIUsman Harun was deployed to search forblack boxes as the ship is equipped with theThales Underwater Systems TMS 4130C1 hull-mounted sonar.[9][10]
On 11 January 2020, KRIUsman Harun was shadowed byChina Coast Guard ships5202 and5203 off theNatuna Regency.[11]
