US: A top U.S. Air Force procurement official has just revealed that Lockheed Martin will face stiff competition from Boeing and Northrop Grumman for a GPS satellite contract. Lockheed fell behind 18 months to complete the first of the eight GPS III satellites it was to deliver under a contract it won in 2008. While Boeing has expressed its interest to compete for the next batch of 22 satellites, Northrop is also excited with this opportunity. It should be noted that the new GPS III satellites come with increased accuracy for navigation. They also have greater resistance against jamming, which has off-late become a top concern for the Pentagon.
