Description
The Bung Tomo class consists of three multi-role light frigates operated by the Indonesian Navy. Developed by BAE Systems Marine as a variant of the F2000 design, the vessels were originally ordered for the Royal Brunei Navy as the Nakhoda Ragam class. Construction took place between 1998 and 2002 at the Scotstoun shipyard in Glasgow. Following a dispute regarding technical specifications and subsequent arbitration, the ships remained in storage until Indonesia purchased them in 2013. The class entered Indonesian service in 2014.
The vessels utilize a diesel propulsion system driving two shafts. The design incorporates a flight deck for medium-sized helicopters, such as the Eurocopter AS565 Panther, though the ships lack an onboard hangar. Sensor suites include hull-mounted sonar, air and surface search radars, and electro-optic weapons directors. A modernization program for the class began in 2020, involving the installation of the TACTICOS combat management system, SMART-S Mk2 3D radar, and updated tactical data links to provide connectivity with other Indonesian military units. The ships have also undergone armament updates, with older anti-ship missiles replaced by newer variants in 2023 and 2024. The original surface-to-air missile systems were deactivated in 2018, with modernization plans specifying the integration of vertical launch missile systems.
In late 2014 and early 2015, KRI Bung Tomo and KRI Usman Harun conducted search and recovery operations following the crash of Indonesia AirAsia Flight 8501 in the Java Sea. KRI Usman Harun utilized its hull-mounted sonar during efforts to locate the aircraft's flight recorders. KRI Bung Tomo was later deployed in April 2021 to assist in the search for the missing submarine KRI Nanggala. The naming of the ships commemorates figures from Indonesian history, including Sutomo, John Lie, and personnel involved in the 1965 MacDonald House bombing.
