Lockheed Martin has been awarded a $4.9 billion contract to build a triad of missile-warning satellites for the U.S. Space Force.
Military forces have a long association with spaceflight, with modern rockets evolving from missiles developed during World War II. Today's armed forces rely on space-based assets for reconnaissance, weather tracking, communication, navigation and more. The U.S. Air Force regularly launches GPS and missile-defense tracking satellites, and operates two classified X-37B robotic space planes.
