[13] Boeing and Lockheed Martin were each awarded US$500 million for the final phase of the bid. SpaceX and ULA were the two vendors selected via the competition to supply launches to the US military in the 20222027 timeframe. Along with the award of two development agreements, the total amount was more than $3 billion. 0000068216 00000 n <> %%EOF [8] Some of the reasons why assured access to space is a priority for the United States are stated in National Presidential Directive Number 40, which reads: Access to space through U.S. space transportation capabilities is essential to: The United States, therefore, must maintain robust, responsive, and resilient U.S. space transportation capabilities to assure access to space. The EELV program is a funded U.S. Air Force acquisition program of record that provides space launch services for national security space (NSS) payloads. %%EOF [3][4], On 1 March 2019, the program name was changed from EELV to National Security Space Launch (NSSL) to better reflect the growing commercial launch market and the changing nature of launch contracts, including the potential for reusable launch vehicles. One of the Air Forces long-term goals for the EELV program is to have at least two certified launch providers able to compete for the full range of national security launches. [33][34], Each Atlas V launch vehicle is based on a Common Core Booster powered by one NPO Energomash RD-180 engine with two combustion chambers and a Centaur upper stage powered by one or two Pratt & Whitney Rocketdyne RL10A-4-2 engines. As of 2019, the first flight has been stated by NGIS to be expected in 2021. 1a-,,3o WYLd ,/HHVYNE^IUAQM]OGK\H[W&?'#/+/P3KrxTDl\BJX|jbRdtLQn~qIN^AvZizaFfVCYumUcEkSe}KysM]&On;,Z2}sl +7^j[Xcm,?p._.
