We’re proud to announce that we have recently secured a contract worth approximately £3 million with Indonesian state-owned defence and electronics company PT Len for the supply of our SeaEagle Fire Control Electro-Optical (FCEO) systems for two Indonesian Navy Bung Tomo-class multi-role light frigates (MRLF).

This contract builds on an existing programme between Chess Dynamics and PT Len, which began with an initial order for the first Bung Tomo-class vessel in 2023. The latest order covers ships two and three, completing the planned class-wide upgrade with SeaEagle FCEO systems.

The Bung Tomo-class multi-role frigates entered service in the early 2000s and are undergoing refurbishment to extend their operational life and maintain combat effectiveness. Our SeaEagle FCEO systems will replace legacy electro-optical fire control equipment, providing a modern capability designed to integrate with the vessels’ existing 76 mm OTO Melara naval guns and interface with the upgraded Thales TACTICOS Combat Management System.

We already have an established presence in Indonesia, following the successful installation of our SeaEagle FCEO systems on Indonesian Navy KCR-60 vessels as part of the combat systems delivered and integrated by Terma.

This contract forms part of our increasing focus on supporting navies across Southeast Asia and the wider Asia-Pacific region. We have supported naval programmes in Southeast Asia for more than 15 years, including programmes in Thailand and Malaysia, while in Australia, we have an established partnership with Owen International to support the local maintenance, repair and upgrade capability of the SeaEagle family.
