France selects Safran HRG navigation technology for nuclear deterrence programmes

Safran Electronics & Defense announced on 2 November 2026 that France selected its hemispherical resonator gyroscope technology for three inertial navigation programmes supporting the country’s nuclear deterrent. The selections cover future submarines, the M51.4 submarine-launched ballistic missile and Rafale combat aircraft, extending Safran’s work on navigation systems that can operate independently of satellite signals. Separately, Safran plans to increase annual gyroscope output from 10,000 to 30,000 units by 2032 across its wider business. The company announced a €120 million investment in its Montluçon facility in June to support that broader production expansion.
