A new EELV Acquisition Strategy was approved in November 2011 which recognizes only the Atlas V and Delta IV can currently provide reliable launch services to meet NSS requirements but also seeks to take advantage of the growing potential of additional commercial space launch providers. The strategy invests in new and/or upgraded commercial launch solutions that also meet National Security Space (NSS) requirements. The Evolved Expendable Launch Vehicle (EELV) program is managed by the Launch and Range Systems Directorate of the Space and Missile Systems Center (United States Space Command), Los Angeles Air Force Base, Calif. Either a 4m or 5m fairing encapsulates the payload. [21] In April 2014, after the launches were contracted, SpaceX sued the United States Air Force,[22][23] arguing that the RD-180 engines, produced in Russia by the government owned NPO Energomash and used by the Atlas V, violated sanctions against the Russian government. The payload interface at each port has been standardized, allowing for hosted and separable payload interchangeability, late payload integration and manifest changes. The Atlas V provides medium and intermediate lift capability and is evolved from flight-proven Atlas and Titan programs, maximizing flexibility and reliability. xref /TT4 11 0 R >> >> The ESPAStar platform's 6 payload ports are capable of accommodating combi-nations of hosted or separable (fly-away) payloads. ULAs use of these tactics artificially created a need for relief from legislative restrictions on its ability to continue using RD-180relief that, with the DoDs active assistance, ULAs actively sought in the fiscal year 2016 omnibus appropriations bill. If that was the case, then the Air Force will have developed a new family of launch vehicles that would be primarily used only for national security payloads, resulting in higher overhead costs to DoD, while missing an opportunity to maximize the competitive posture of US industry. 7 0 obj endstream Delta IV Medium flew with two or four SRBs on a single Common Booster Core. The EELV system includes all equipment, facilities, and launch base infrastructure necessary to launch a payload, place it in the required delivery orbit, provide specified environments, provide. After many years of government-funded studies on the subject of modernized launch vehicle systems, the Air Force finally developed a "roadmap" in 1994 for the acquisition of Evolved Expendable Launch Vehicles (EELVs) to replace the DELTA IIs, ATLAS IIs, and TITAN IVs then in use at Cape Canaveral. hb```B ;6hvfa. Boeing initially proposed using the RS-25 Space Shuttle main engine. The Delta IV Heavy launch vehicle uses three Common Booster Cores (CBCs) each powered by a Pratt and Whitney Rocketdyne RS-68A engine, a Delta Cryogenic Second Stage 5m (DCSS) powered by an RL10, and a 5m payload fairing. Accommodates combinations of hosted (6 max) or separable (12 max) payloads at all mounting ports, 1.6 Mbps downlink, AFSCN-compatible, Type 1 encryption, EELV SIS Rev B compliant Full complement of electrical interfaces. [11], In October 1998 two initial launch services contracts (known as Buy 1) were awarded. 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. endstream endobj 638 0 obj <>/Metadata 52 0 R/Pages 635 0 R/StructTreeRoot 114 0 R/Type/Catalog>> endobj 639 0 obj <>/MediaBox[0 0 612 792]/Parent 635 0 R/Resources<>/Font<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI]/XObject<>>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 640 0 obj <>stream trailer <<8D9465B782A042F99BA9A4986B1592D1>]/Prev 881083>> startxref 0 %%EOF 59 0 obj <>stream The EELV program's Delta IV and Atlas V launch vehicles are produced by United Launch Alliance (a joint venture of Boeing and Lockheed Martin formed in 2006).
