The Bung Tomo class is a class of three Indonesian multi role patrol corvettes or Multirole Light Frigates (MRLF) by Indonesia. They were originally built for the Royal Brunei Navy and named Nakhoda Ragam-class corvettes but were ultimately bought by Indonesia and renamed. The class is named after Bung Tomo, a noted leader of Indonesia's independence movement. Background 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. In 2007, Brunei contracted the German Lürssen shipyard to find a new customer for the three ships. In 2013, Indonesia bought the vessels for or half 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 Operational history In late December 2014, KRI Bung Tomo was involved in search and recovery operations of the Indonesia AirAsia Flight 8501 which crashed off the Java Sea between the islands of Belitung and Borneo.
