The Indonesian Navy (TNI-AL) is expected to proceed with the mission system modernization of one of its Bung Tomo-class multirole corvettes, the KRI Usman-Harun (359).

The project will be undertaken by state-owned electronics company PT LEN Industri in partnership with Thales Group, which signed a contract on 10 March 2020. PT LEN Industri is the appointed system integrator for the project, with Thales to provide technical assistance and the products to be used for the upgrade.

The project will see the installation of the Thales TACTICOS Combat Management System, the SMART-S Mk.2 air and surface surveillance radar, the STIR EO Mk. 2 fire control radar and EO fire control system, and the Vigile Mk.2 tactical multipurpose Radar-Electronic Support Measures (R-ESM) system. 

The said subsystems are the same as those already installed on the TNI-AL’s new Martadinata-class frigates, which allows for commonality and consistency between the naval assets.

The modernization program enables the TNI-AL to have a cost-effective way of extending the ship’s life cycle while improving its capabilities for optimum performance. The works are expected to be completed by late 2023,

The upgrade works will be PT LEN Industri’s first major mission modernization and integration program, and would enable it to build on its capabilities after receiving technical support and technology transfer from Thales.
