Orbital Sciences Corporation (commonly referred to as Orbital) was an American company specializing in the design, manufacture, and launch of small- and medium- class space and launch vehicle systems for commercial, military and other government customers. In 2014, Orbital merged with Alliant Techsystems (ATK) to create a new company called Orbital ATK, which in turn was purchased by Northrop Grumman in 2018. Orbital was headquartered in Dulles, Virginia and publicly traded on the New York Stock Exchange with the ticker symbol ORB. Orbital's primary products were satellites and launch vehicles, including low Earth orbit (LEO), geosynchronous Earth orbit and planetary spacecraft for communications, remote sensing, scientific and defense missions; ground- and air-launched launch vehicles that delivered satellites into orbit; missile defense systems that were used as interceptor and target vehicles; and human-rated space systems for Earth orbit, lunar and other missions. Orbital also provided satellite subsystems and space-related technical services to government agencies and laboratories. On April 29, 2014, Orbital Sciences announced that it would merge with Alliant Techsystems to create a new company called Orbital ATK. The merger was completed on February 9, 2015, and Orbital Sciences ceased to exist as an independent entity. On September 18, 2017, Northrop Grumman announced plans to purchase Orbital ATK for US$7.8 billion in cash plus assumption of US$1.4 billion in debt, and on June 6, 2018, the acquisition was completed, and Orbital ATK became Northrop Grumman Innovation Systems. As of January 1, 2020, the name was changed to Space Systems under a large restructuring and rebranding initiative.
History Orbital was founded and incorporated in 1982 by three friends who had met earlier while at Harvard Business School—David W. Thompson, Bruce Walker Ferguson, and Scott L. Webster. Initial capitalization for Orbital was provided by Fred C. Alcorn, a Texas oilman and Sam Dunnam, a Texas businessman in September 1982. In 1985, Orbital procured its first contract for providing up to four transfer orbital stage (TOS) vehicles to NASA. In 1987, the seeds for the Orbcomm constellation were planted when Orbital began investigating a system using low Earth orbit (LEO) satellites to collect data from remote locations. In 1988, Orbital acquired Space Data Corporation in Arizona—one of the world's leading suppliers of suborbital rockets—thereby broadening its rocket business and manufacturing capabilities. This was followed by the opening of a new facility in Chandler, Arizona in 1989 to house the company's expanding rocket business. In 1990, the company successfully carried out eight space missions, highlighted by the initial launch of the Pegasus launch vehicle, the world's first privately developed space launch vehicle (the claim of being the first privately developed space launch vehicle can be contested as Pegasus received significant funding from NASA and DARPA, and a predecessor private rocket exists, the Conestoga rocket). Shortly following the successful Pegasus launch, Orbital conducted an initial public offering (IPO) in 1990 and began trading on the NASDAQ stock exchange. In 1993, Orbital established its headquarters in Dulles, Virginia. In 1994, Orbital successfully conducted the inaugural launch of the Taurus (now renamed as Minotaur-C) launch vehicle. In the early 2000s, Orbital continued expanding its missile defense systems business with a US$900 million award to develop, build, test and support interceptor booster vehicles. In 2006, Orbital conducted its 500th mission since the company's founding with products that included satellites, launch vehicles, and missile defense systems. In 2007, the first interplanetary spacecraft built by Orbital, Dawn was launched on an eight-year, three-billion-mile journey to the main asteroid belt between Mars and Jupiter. A major milestone in the company's history was in 2008 when it received a long-term NASA contract to provide cargo transportation services to and from the International Space Station (ISS) with a value of approximately US$1.9 billion for missions from 2011 to 2015. Orbital used its Cygnus spacecraft and Antares launch vehicle to transport cargo to ISS following the success of Cygnus Orb-D1 and Cygnus CRS Orb-1.
Acquisitions Orbital Science made a number of strategic acquisitions in the 1990s and 2000s to strengthen its position in the satellite market. In 1994, Orbital completed acquisition of Fairchild Industries' subsidiary Space and Defense Corporation, and merged the Fairchild Space business with its own satellite design and manufacturing division. The electronics business of this subsidiary was later sold off in 2000. In 1997, Orbital acquired CTA, Inc, a company that, under the spacecraft design engineering and business leadership of Tom van der Heyden – designer of the GEOStar spacecraft – had designed and built the first geostationary "lightsat" under contract to Indonesia for Asia's first Direct Broadcast Satellite (DBS) television broadcast program, and the world's first S-Band television broadcast satellite – providing an entry into the fast-growing Geosynchronous (GEO) communications satellite market. In 2010, Orbital acquired the Gilbert, Arizona-based satellite development and manufacturing unit from General Dynamics (General Dynamics Advanced Information Systems, formerly Spectrum Astro) to complement its main satellite manufacturing facility in Dulles, Virginia.
Merger On April 29, 2014, Orbital Sciences announced that it had entered into a definitive agreement with Alliant Techsystems to combine Orbital and ATK's Aerospace and Defense (A&D) Groups to create a US$4.5 billion (combined calendar year 2013 annual revenue), 13000-person company. The new company was called Orbital ATK, Inc. On September 18, 2017, Northrop Grumman announced plans to purchase Orbital ATK for US$7.8 billion in cash plus assumption of US$1.4 billion in debt. Orbital ATK shareholders approved the buyout on November 29, 2017. The Federal Trade Commission (FTC) approved the acquisition with conditions on June 5, 2018, and one day later, Orbital ATK were absorbed and became Northrop Grumman Innovation Systems.
