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. As of that time, Vulcan Centaur was on track for a 2021 launch. [11], In October 1998 two initial launch services contracts (known as Buy 1) were awarded. [24] The USAF and SpaceX settled the lawsuit in Jan 2015 by opening up more launches to competitive bidding. The USAF began the EELV program in 1994, following many years of government-funded studies into improved systems and architecture. For example, in order to meet its projected reductions in life cycle costs, the EELV needed to capture at least 15 percent of the commercial market.

That strategy was designed to (1) . [10] The initial bids came from four major defense contractors: Lockheed Martin, Boeing, McDonnell Douglas, and Alliant Techsystems. Senator Richard Shelby is from Alabama. [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. DOD's Evolved Expendable Launch Vehicle (EELV) program is the primary provider of launch vehicles for U.S. military and intelligence satellites. The Atlas V provides medium and intermediate lift capability and is evolved from flight-proven Atlas and Titan programs, maximizing flexibility and reliability. Shelby was a loyal supporter of ULA, and attempted to shoehorn in money to buy the RD-180 engines from Russia, against the wishes of Senator McCain and the rest of the Armed Services Committee. 0 This requirement has been satisfied by the Falcon Heavy test flight in February 2018, Arabsat-6A in April 2019, and the STP-2 launch in June 2019. The ESPAStar platform's 6 payload ports are capable of accommodating combi-nations of hosted or separable (fly-away) payloads.

That includes five engines that ULA currently has in its possession, which are not limited by the sanctions, since they were fully paid for prior to the Russian invasion of Crimea. 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. endstream << /Length 22 0 R /Filter /FlateDecode >> %%EOF @media only screen and (min-device-width : 320px) and (max-device-width : 480px) { .
