South Korea orders its 100th Sigma 40 navigation system from Sagem

South Korea has ordered its 100th shipborne Sigma 40 inertial navigation system from Sagem (Safran group), confirming its confidence in the system’s laser gyro technology.

The Sigma 40 is a high-performance shipborne inertial navigation system. It is available in several different versions to cover operational needs for all types of warships, from corvettes to nuclear submarines.

These units are widely used by the South Korean navy as original equipment or higher-performance retrofits on both surface vessels and submarines, including PKX patrol boats, FFX frigates and U-209 and KSS-1 submarines.

This latest Sigma order consolidates Sagem’s leadership with the world’s most powerful navies. Part of the ship’s combat system, the Sigma 40’s high-precision measurements contribute to weapon accuracy and performance.

Sagem’s Sigma 40 navigation systems now handle the main navigation function on more than 300 surface vessels (corvettes, frigates, aircraft carriers) and over 50 submarines in 11 different classes, including nuclear (Rubis-Améthyste class), non-nuclear air-independent propulsion (AIP) and conventional propulsion models.
