State-owned India Optel Limited signed a collaboration agreement with France's Safran Electronics & Defense for transfer of production of two systems in India: the SIGMA 30N Digital Ring Laser Gyro Inertial Navigation System and the CM3-MR Direct Firing Sight. SIGMA 30N is used in artillery guns, air defence systems, missiles and radars; CM3-MR is designed for artillery guns and anti-drone systems. The agreement supports local manufacturing, final assembly, testing, quality control and life-cycle support for the Indian Army under India's defence-indigenisation push.
