French navigation system for Indonesian new submarines

The South Korean shipbuilder Daewoo Shipbuilding & Marine Engineering (DSME) has chosen Sagem of French group Safran to supply SIGMA 40XP inertial navigation systems for three U209 based diesel-electric powered attack submarines ordered by Indonesia in 2012.

Each submarine for the Indonesian Navy (Tentara Nasional Indonesia Angkatan Laut or TNI-AL) will be equipped with two of the SIGMA 40XP laser gyro inertial reference unit and associated equipment.

DSME will build two submarines in South Korea in partnership with the Indonesian shipbuilder PT PAL Indonesia and the third submarine will be constructed in Indonesia.

As part of their navigation suite, the submarines will also be equipped with ECPINS-W Sub electronic chart display and information system from OSI Maritime Systems. Indra of Spain was earlier awarded a contract to supply the submarines with the company’s Aries-S low probability of intercept radar and Pegaso electronic warfare system.

The Indonesian Navy currently operates other three U209-1300 attack submarines that were brought in 1977 from ThyssenKrupp Marine Systems (TKMS) of Germany.

SIGMA 40XP technology will also fits the planned six Barracuda nuclear powered attack submarines of Suffren Class for French Navy operation, of which three were already contracted (Suffren, Duguay-Trouin and Tourville) to DCNS by the French procurement agency DGA (Direction Générale de l’Armement), with first scheduled to be delivered in 2017, and as well as the diesel-powered attack submarines purchased by Brazil and India to DCNS.
