Orbital Sciences Corporation has sued ULA seeking damages of between $515 million to $1.5 billion for blocking sales of the Russian-built RD-180 that Orbital wants to use in its Antares launch vehicle, Space News reports.
Orbital of Dulles, Va., claims Denver-based ULA has not only illegally prevented open-market sale of the RD-180, but also has monopolized the launch-services market for certain satellites in violation of U.S. antitrust laws, according to a complaint filed June 20 with the U.S. District Court for the Eastern District of Virginia in Alexandria.
