The Indonesian Navy is equipping its new class of two 90 m offshore patrol vessels (OPVs) with a Turkish combat management system (CMS) and weapons for anti-submarine and anti-ship operations.

Schematic diagrams and other official documents forwarded to Janes by an industry source confirm that the Indonesian Navy has selected the Advent combat system from Turkish software company Havelsan.

The system will be supplied with five operator consoles on a vessel combat network that has one electro-optical (EO) targeting system turret, a combined radar and EO-based fire-control system, a navigation radar, and a surveillance radar integrated with an identification friend-or-foe system.

The CMS will also be linked to a 76/62 Super Rapid (SR) naval gun – presumably from Italian defence company Leonardo – with provisions for a 35 mm naval gun system, two 20 mm cannons, anti-surface missiles, a variable-depth sonar system, decoy launchers, and an electronic warfare radar.

A computer-generated image of the vessel provided by shipbuilder PT Daya Radar Utama (PT DRU) indicates that the navy intends to equip the OPV with four anti-surface missile launchers mounted amidships. The image also depicts a 35 mm naval gun system in the aft section facing the flight deck, but it is unclear where the 20 mm guns will be located.

However, except for the 76 mm naval gun, Janes has been informed that selection processes for the remaining weapons are yet to begin and provisions for these systems in the CMS architecture will be made on a fitted-for-but-not-with basis.
