Len Industri, Thales to Modernize Indonesian Navy Light Frigate KRI Usman-Harun

Len Industri and Thales signed a contract for the complete modernization of the Indonesian Navy (TNI-AL)’s multi-role light frigate, KRI Usman-Harun (359).

The contract was signed on 10 March in Jakarta witnessed by King Willem Alexander of the Netherlands and Indonesian Minister of Trade Agus Suparmanto.

Len Industri is the systems integrator for the KRI Usman-Harun’s Mid Life Modernisation (MLM) program. The modernization program is the company’s first major mission modernization and its first mission systems integration program.

The contract will see Len Industri and Thales install the TACTICOS Combat Management System, the SMART-S Mk2 air and surface surveillance radar, the STIR EO Mk2 radar and EO fire control system and the Vigile Mk2 tactical multi-purpose R-ESM system. These systems are currently also installed on the Indonesian Navy’s new Raden Eddy Martadinata class frigates, enabling consistency in operations for the Navy, and ensuring that their fleet remains one of most advanced in the region.

This upgrade for the KRI Usman-Harun is expected to be completed by the end of 2023, and it will considerably extend the life of the frigate.

“This contract underlines the excellent relations between the Republic of Indonesia, Len Industri and Thales. The program will strongly contribute to the independence of the Indonesian defence industry and lays a strong foundation for future naval contracts, both for new builds as well as modernizations”, Erik-Jan Raatgerink, Country Director, Thales in Indonesia.

Thales has established strong credentials in naval modernization worldwide. In Indonesia, Thales has supplied and integrated the naval combat electronics for four Sigma class corvettes and is also the supplier and integrator of the naval mission systems for the current Indonesian Raden Eddy Martadinata Frigate program.

KRI Usman-Harun (359) is the third Bung Tomo-class of multi-role patrol corvettes/light frigates in service with the Indonesian Navy (TNI-AL).

The corvettes 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.

The three Bung Tomo-class vessels were built by BAE Systems Marine (now BAE Systems Maritime – Naval Ships) at its shipyard in Scotstoun, Glasgow.

KRI Usman-Harun has a length of 89.9 m and displaces 1940 tonnes. The vessel is capable of achieving a top speed of 30 knots (56 km/h) and has a range of 5,000 nautical miles (9,000 km) at 12 knots.

The main gun of the vessel is an Oto Melara 76 mm cannon. It is also armed with two triple BAE Systems 324-millimetre (13 in) torpedo tubes and two 30mm DS30M Mark 2 Automated Small Calibre Gun remote weapon stations (RWS)

The ship also has a landing spot for a helicopter.
