About Northrop Grumman Aerospace Structures

Northrop Grumman Aerospace Structures (formerly Alliant Techsystems/ATK, headquartered in Clearfield, Utah) is Northrop Grumman's composite structures and spacecraft bus division, one of North America's largest manufacturers of spacecraft structural assemblies. The division produces primary and secondary composite structures for satellite buses (Cygnus spacecraft bus), antenna reflectors (including large deployable mesh and solid reflectors for GEO communications satellites), rocket motor cases, and launch vehicle components including fairings and interstages. The Clearfield, Utah facility spans several manufacturing complexes and supports commercial satellite primes (Boeing, Northrop's own programs), NASA science missions, and military satellite programs. The division's carbon fiber composite manufacturing expertise is a critical enabler for lightweight spacecraft structures where mass directly translates to launch cost or mission capability.
