Northrop Grumman wins $29.2 million Navy contract for AN/WSN-12 navigation systems

Northrop Grumman has won a $29.2 million U.S. Navy contract for low-rate initial production units and maintenance assistance modules for the AN/WSN-12 inertial navigation system, along with engineering support, integration, and testing. The award includes multiple contract types with a potential cumulative value of $103.6 million if all options are exercised. The shipboard system is designed to deliver position, velocity, and attitude data when GPS is unavailable or unreliable. It uses fiber-optic gyroscope technology and is intended as a form-fit-function replacement for the legacy AN/WSN-7, enabling backfits and installation on new platforms. Work will be performed in Charlottesville, Va., and Baltimore, and runs through May 2030, with options extending to July 2032.
