摘要

The U.S. Air Force contends United Launch Alliance needs as many as 22 RD-180 rocket engines to compete against SpaceX for dozens of national security launches that start going out for bid later this year, according to a U.S. senator. ULA has ordered 29 RD-180 engines from Russia for its Atlas 5 rocket. Fifteen of those engines are for Air Force launches already under contract. The remaining 14 are what ULA has said it needs to import in order to compete for military launches until its next generation rocket, known as Vulcan and powered by a U.S.-made engine, is ready around 2020.
