General Dynamics Decision Systems, a business unit of General Dynamics has been awarded a $611 million contract by the U.S. Coast Guard to modernize its 30- year-old search and rescue communication system. The National Distress and Response System Modernization Project (NDRSMP), called "Rescue 21," will greatly improve the Coast Guard's ability to detect mayday calls from boaters, pinpoint the location of the source and coordinate rescue operations along the 95,000-mile U.S. coastline and interior waterways. Admiral Thomas H. Collins, Commandant of the Coast Guard, said, "The General Dynamics proposal was evaluated as providing the best overall value to the government that met all of our requirements.
