F-35 Navigation Systems Get $114.6M Lockheed Martin Redesign as GPS and INS Parts Go Obsolete

Naval Air Systems Command awarded Lockheed Martin a $114.6 million order to redesign the F-35 Lightning II’s GPS Electronic Unit and NAV100 inertial navigation system because their electronic components are becoming obsolete. The effort covers engineering, integration, qualification and testing of replacement hardware intended to preserve existing navigation functions and compatibility, rather than introduce a new combat capability. Work is scheduled across El Segundo, Fort Worth and Clearwater, with completion expected in January 2030. U.S. Air Force and Navy aircraft procurement funds cover roughly $92.8 million, while F-35 international partners contribute $21.8 million; all funding was obligated at award.
