Instead of setting those engines aside for national security launches, ULA rushed to assign them to non-national security launches that are unrestricted in their use of Russian engines. This could include full development of a new launch system or modifications to an existing launch system, including launch infrastructure. Up to five Aerojet Rocketdyne Graphite-Epoxy Motor solid rocket boosters can be added to increase vehicle performance, and two diameters of payload fairing are available. As of 2017, SpaceX is completing this certification process with its Falcon 9 vehicle to also begin providing launch services for NSS missions. %%EOF 651 0 obj <>/Filter/FlateDecode/ID[<6EC1C2F151EC3C45B8B5ECDBB3EB3C71><0EADE15319BF1E45AF492E40E1E9E55A>]/Index[637 42]/Info 636 0 R/Length 86/Prev 989486/Root 638 0 R/Size 679/Type/XRef/W[1 3 1]>>stream ( (ZY deZyo|-@#|Fd3C\5t Blue Origin was awarded $500 million of phase 1 funding for further development of New Glenn as a potential competitor in future contracts.
