Sagem, in disclosing the contract from Daewoo Shipbuilding & Marine, did not disclose the value of the contract or the number of systems to be delivered.
For the order, Sagem's navigational system will be comprised of two high-performance Sigma 40XP laser gyro inertial reference units, a computer and safety-critical navigation software, which will contribute to the submarines' stealth and safety during dives.
"This latest contract underscores the quality of the relationship between Korean industry and Sagem on navigation systems, and the predominance of laser technology in submarine navigation systems," Sagem said. "South Korea's Defense Acquisition Program Administration had already chosen Sagem recently to modernize the navigation system on the country's KSS-1 Chang Bogo submarines class [and] several modernized submarines are already in full operation at sea."
Indonesia ordered 1,400-ton submarines from South Korea last year.
