Navy asks Northrop Grumman to supply deck navigation systems for new and existing Burke-class destroyers

WASHINGTON- US Navy shipboard electronics experts ask Northrop Grumman Corp. to build deck navigation systems for Arleigh Burke-class guided-missile destroyers (DDG 51) as part of a $12.2 million order announced on Tuesday.

Naval Sea Systems Command officials in Washington are requesting the Northrop Grumman Mission Systems Segment in Charlottesville, Va., to provide Integrated Bridge and Navigation Systems (IBNS) for the new Burke-class destroyers, as well as the upgrades to existing ships of this class.

These integrated bridge and navigation systems for surface warfare vessels are part of the DDG-51 New Construction Ship Program and the DDG-51 Quarantine Modernization Program, Navy officials said.

The IBNS is a hull, mechanical and electrical upgrade to modernize Burke-class destroyers to ensure the ships remain affordable and combat-ready throughout their life cycle.

Northrop Grumman Military Integrated Bridge Systems manage the automated collection, processing, control, and display of vessel control data and navigational sensors to help make the most of effective bridge surveillance and vessel control security.

These systems combine voyage planning and real-time monitoring of bridge navigation; track steering vessel control; radar contact track and video overlay; interfaces with machine control systems; mobile harbor and aquatic space management; positional uncertainty fixed expansion; position navigation cue lines; commander password protection of approved travel plans; electronic bearing lines and variable range; graphic markup; operator text overlay; operating areas; areas of uncertainty beyond the horizon; joint tactical action zones; and search areas generated by submarines.

Components of IBNS include the Voyage Management System (VMS), a computerized navigation, planning and monitoring system. It meets the requirements of the US Navy Electronic Chart Display and Information System – Navy (ECDIS-N) and provides tools for the ship’s crew to navigate electronically.

The Automated Radar Plotting Aid (ARPA) system which automatically acquires and tracks contacts of the ship’s bridge watch team is also part of IBNS.

The IBNS also has the Ship Control System (SCS) which provides command and control signals to the ship’s control and propulsion systems and monitors their performance.

Northrop Grumman Integrated Military Bridge Systems are deployed aboard US Navy aircraft carriers, cruisers, destroyers, amphibious assault ships, submarines and landing craft, as well as aboard NOAA ships, Coast Guard icebreakers and International Navy ships.

On this order, Northrop Grumman will perform the work in Charlottesville, Virginia, and is expected to be completed by December 2023.
