Estimated reading time: Less than a minute

Northrop Grumman Corporation has successfully completed the Preliminary Design Review (PDR) for the Inertial Sensor Module, a critical component of the U.S. Navy's Inertial Navigation System Replacement (INS-R). The system will be named WSN-12, and will replace the WSN-7.

The PDR, a key milestone for the program, is one of four major system engineering technical reviews. Engineering Development Models are currently being built, with deliveries planned for mid-2017.

"This is a critical system for both surface and subsurface platforms," said Todd Leavitt, vice president, maritime systems business unit, Northrop Grumman. "It took a lot of focused energy and close coordination with the Navy to achieve this milestone in only four months."

Barbie Fidura, Navsea PEO IWS 6.0 Navigation Programs, said, "This was a big effort for both the Navy and Northrop Grumman, and I am pleased about how we worked together to make this happen. INS-R is an important system and a foundation for assured positioning, navigation, and timing requirements."
