The Chief of Naval Operations has approved an upgraded electronic navigation system for Navy submarines that will allow vessels to better navigate in northern latitudes and under-the-ice operations.

The upgrade, designed by Northrop Grumman Corp.’s Sperry Marine business unit based in Charlottesville, received approval for Version 8.3 of its Voyage Management System (VMS). The system is the standard naval electronic chart display and information system that is used in the Navy’s surface ships and submarines. Currently, 58 U.S. nuclear submarines are equipped with Sperry Marine’s VMS-based navigation systems.

Approval of the design required testing at the Naval Surface Warfare Center, Port Hueneme’s Virginia Beach detachment.

“With VMS, the navigation team can view the submarine’s real-time position and movement superimposed, along with radar images, on a digital nautical chart showing all the aids and hazards to navigation — a revolutionary improvement over manual plotting on paper charts,” J. Nolasco DaCunha, vice president of the Sperry Marine unit said in a statement.
