Combat Systems Installed on Indonesian Frigate

Combat systems were recently installed and tested aboard the second of the Indonesian Ministry of Defence’s SIGMA 10514 Perusak Kawal Rudal (PKR) guided missile frigates, the KRI Gusti Ngurah Rai (332).

The PKR frigates are constructed via a modular process operating simultaneously at Damen Schelde Naval Shipbuilding (DSNS) in the Netherlands and the PT PAL shipyard in Indonesia.

This method, which allows the Damen Shipyards Group to build vessels anywhere in the world, enables Damen to fulfil its commitment to the Indonesian Ministry of Defense to deliver an extensive knowledge and transfer of technology (ToT) program. Part of this transfer program is the installation of combat systems along with provision of training to the crew in their usage and maintenance.

Hein van Ameijden, managing director of DSNS, said, “From the outset of this project DSNS and our partner Thales Netherlands have been fully committed to the development of the Indonesian defense industry and its supporting sectors. This commitment is demonstrated with a series of ToT and local content programs starting in 2013 when project execution commenced.

“For example, DSNS has trained and educated more than 328 yard personnel, including welders, planners and engineers, during the project. Thales Netherlands has contributed by subcontracting local industry for software development, providing support, ultimately, for Indonesia to develop an indigenous combat management system.”

The combat systems installed and tested include the following:

• VL MICA for defense from airborne threats
• Exocet for defense from offensive targets at greater distance
• Torpedo system for protection against submarine threat
• 35mm rapid-fire cannon to respond to threats from both air and sea
• Electronic detection system to divert enemy attacks with electromagnetic redirection
• Modification of the computer operated operational system in order to operate the above

The final phase prior to handover was completed on February 21 with sea trials – the sea acceptance test (SAT). The purpose of this was to demonstrate that installations throughout the entire chain of weapons systems meet desired efficiency and accuracy.

“All our prior efforts paid off. Already at the start of the tests it was clear that installation had been carried out with great precision during construction and that preparatory alignment activities and agreements had been carefully followed. The second PKR vessel achieved similar results to the first one. This demonstrates that the complete concept implemented in the SIGMA PKR Class can be considered reliable and robust,” said Van Ameijden.
