The Bung Tomo class is a class of three Indonesian multi role light frigates. They were originally built for the Royal Brunei Navy and named Nakhoda Ragam-class corvettes but were ultimately bought by Indonesia and renamed.[5] 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.[6]

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.[7] 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.[8]

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.[9] Later in early January 2015, KRI Usman Harun was deployed to search for the black boxes as the ship iss equipped with the Thales Underwater Systems TMS 4130C1 hull-mounted sonar.[10][11]

Ships of the class

KRI Bung Tomo is named after Sutomo, the leader of Indonesian guerrillas during the Battle of Surabaya. The naming of KRI John Lie memorializes a National Hero of Indonesia who was one of the first high ranking navy commanders during the Indonesian National Revolution. The naming of KRI Usman-Harun memorializes Harun Said and Osman Hj Mohd Ali, who were executed by Singapore after the MacDonald House bombing, creating a controversy between the two nations.[12]
