KDB Bendahara Sakam (29)

The three vessels were built by BAE Systems Marine (now BAE Systems Maritime - Naval Ships). The contract was awarded to GEC-Marconi in 1995 and the ships, a variant of the F2000 design, were launched in January 2001, June 2001 and June 2002 at the then BAE Systems Marine yard at Scotstoun, Glasgow. The customer refused to accept the vessels and the contract dispute became the subject of arbitration. When the dispute was settled in favour of BAE Systems, the vessels were handed over to Royal Brunei Technical Services in June 2007.[1]

In 2007, Brunei contracted the German Lürssen shipyard to find a new customer for the three ships; in November 2012, it was announced that Indonesia had signed a memorandum of understanding with Britain to acquire the vessels for one-fifth of the original unit cost. The ships are now in service with the Indonesian Navy.

The ships were originally armed with MBDA Exocet Block II anti-ship missiles and MBDA 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 2018 the MBDA Seawolf missile was out of service due to expired and there was plan to replace it with VL Mica [2]

KDB Bendahara Sakam was launched on 23 June 2001 and commissioned into the Indonesian Navy on 18 July 2014.[3][4] She originally had the hull number 29 but were later changed to 359. She was never commissioned in the Royal Brunei Navy.

In early January 2015, KRI Usman Harun was deployed to search for the black boxes as the ship is equipped with the Thales Underwater Systems TMS 4130C1 hull-mounted sonar.[5][6]

On 11 January 2020, KRI Usman Harun was shadowed by China Coast Guard ships 5202 and 5203 off the Natuna Regency.[7]

The Singaporean government protested against the naming of KRI Usman Harun. The naming was rejected by Singaporean Foreign Minister K. Shanmugam. The reason is that two people had bombed MacDonald House on Orchard Road. From this incident, three people were killed and made the two marines receive a death sentence in Singapore on 17 October 1968. KRI Usman Harun is banned from entering Singapore ports and sea bases. The affirmation was conveyed by Singapore Defense Minister Ng Eng Hen.[8][9][10]
