In September 2010, Able Engineering was acquired by Alliant Techsystems. Formerly doing business as AEC-ABLE Engineering Company Inc, ATK-ABLE Engineering Inc. (ABLE) ABLE Engineering Inc. is an independent supplier of deployable structures, providing hardware for NASA, the military and nearly every major aerospace prime contractor. In 2004, ATK acquired the PSI Group, a leader in the design and manufacture of components for military and commercial space-based applications, including global positioning, navigation and communication satellites, satellite bus structures, struts, reflectors and deployable mast booms. The acquisition strengthened ATK's advanced space systems portfolio and positions it to capture emerging opportunities in spacecraft integration and satellite technology. ABLE produces deployable booms, solar arrays, antenna structures, and many other aerospace mechanisms while continuing to maintain a 100% in-flight success rate. Boom Systems, Stable Structures, Antenna Systems and Mechanisms Rigid-Panel, Flexible-Blanket, and Concentrator Systems Innovative mechanical/structural and solar array design Production of repeatable, deployable, stable structures & solar arrays Technology development approach. ABLE has leveraged its initial CoilABLE deployment structure into a multiple product line. ABLE continues to develop deployable systems for next generation spacecraft including solar arrays for the next block of GPS satellites, ultra lightweight solar sails to provide near unlimited spacecraft propulsion for certain scientific missions, large deployable trusses for future space based radar and optical systems, and large deployable masts for NASAs new nuclear initiative, Project Prometheus. Deployable structures from ABLE have flown on numerous spacecraft that have traveled throughout our solar system, including the Galileo, Cassini, Lunar Prospector and the Mars Sojourner missions.
