Alliant Techsystems Inc. unveiled its $100 million manufacturing plant for aircraft components in Clearfield Monday, projecting that the 615,000-square-foot facility will increase its capacity to produce composite-fiber parts tenfold. Production at the center, which will serve as the headquarters for ATK Aerospace Structures, is expected to create 800 high-paying jobs over the next 20 years and generate almost $1 billion in wages along the way. The new plant employs 120 workers, but to address increased production ATK anticipates adding 100 employees annually over the next several years. Salt Lake Tribune
