Sagem NAVS selected for Indonesian submarines
Sagem will supply its navigation system (NAVS) to South Korea’s Daewoo Shipbuilding & Marine Engineering (DSME) to be installed on three 1,400 ton ocean-going submarines under construction for the Indonesian Navy.
Sagem’s NAVS will provide the new class of submarine with reliable and precise navigation capabilities. The system comprises two high-performance Sigma 40XP laser gyro inertial reference units, a computer and safety-critical navigation software, all contributing to the submarine’s stealth and safety during dives.
The company beat out international competition for the contract. The award underscores the strong relationship between Sagem and South Korean industry; South Korea’s Defense Acquisition Program Administration previously selected Sagem to modernise the navigation system on the country’s KSS-1 Chang Bogo submarines class, with several modernised submarines already in full operation at sea.
Ordered by Indonesia in 2012, this new class of submarine is the first South Korean-designed submarine to be sold in international markets.
