Northrop Grumman Space Systems (formerly Northrop Grumman innovation system , before Orbital ATK ) is an American aerospace - Armor - and air carriers based in Dulles , Virginia , the 2015 from the merger of Orbital Sciences Corporation and ATK Aerospace and Defense , the Arms division of Alliant Techsystems , which was acquired by Northrop Grumman in 2018 .
The operational business is divided into three areas: flight systems, defense systems and space systems.
history
The space company Orbital Sciences Corporation was founded in 1982 by three befriended Harvard Business School graduates David Thompson, Scott Webster and Bruce Ferguson. Their first product for NASA was the Transfer Orbit Stage (TOS). She became known worldwide when she developed the capacity for supply flights to the International Space Station with the cargo spacecraft Cygnus and the launch vehicle Antares as part of NASA's Commercial Orbital Transportation Services program . Based on this successful development, NASA commissioned the company in 2008 as part of its Commercial Resupply Services program for the period from January 1, 2009 to December 31, 2016 with 8 cargo missions to the ISS for 1.9 billion US dollars .
ATK Aerospace and Defense was formed in 1990 with the spin-off of Honeywell's defense division . By this time Honeywell had been manufacturing military equipment for the United States and for export for 50 years. ATK expanded into the aerospace sector with the acquisition of Hercules Aerospace Company in 1995 and Thiokol Propulsion in 2001. Further acquisitions of companies followed.
Orbital ATK continues to be the only operator worldwide to use the Lockheed L-1011 TriStar as a carrier aircraft for Pegasus missiles . In April 2015 the Stargazer was repainted.
Acquisition by Northrop Grumman
In September 2017, Northrop Grumman announced that it would take over Orbital ATK for a purchase price of around $ 7.8 billion and its existing debt of around $ 1.4 billion. The transaction closed on June 6, 2018.
