The Next Generation Guidance (NGG) program aims to develop the Mk6 LE as a modern replacement that can achieve the same or better performance as the guidance systems that are breaking down. This requires development of precision instruments, sensors, and radiation hardened architectures, in order to adapt the underlying commercial technologies for use in a must-not-malfunction nuclear weapons system.
