Northrop Grumman Corporation has been awarded a service contract for navigation systems and software to support the polar ice breakers for the U. S. Coast Guard. The $5 million, five-year contract covers support for two Coast Guard vessels, the Polar Star and the Healy. These polar ice breakers are used to clear pathways for supply ships and support research missions. Northrop Grumman has provided comparable support for the Coast Guard's polar ice breakers since 1999. Northrop Grumman will supply hardware configuration management, remote technical support and training classes.
