Huntsville may benefit from the White House directive to revamp the nation’s intercontinental ballistic missile arsenal. The Air Force says it has awarded contracts to Boeing and Northrop Grumman for work that could lead to replacement of the nation's intercontinental ballistic missiles. Chicago-based Boeing has built long-range missiles for the Defense Department since Minuteman I in the 1960s. It’s missile-replacement effort will be done in Huntsville, Alabama as well as Utah, Ohio; and other locations. The contracts are part of a planned overhaul of the U.S. nuclear arsenal that will cost tens of billions of dollars. Both Boeing and Northrop Grumman have been involved in the ICBM program for decades.
