The USAF began the EELV program in 1994, following many years of government-funded studies into improved systems and architecture. The contractor was standardizing payload interfaces, launch pads, and infrastructure so that all configurations of each contractor's EELV family can be launched from the same pad and payloads can be interchanged between vehicles in the same class (i.e., medium, intermediate, or heavy). %%EOF Steady production rates, long-term commitments and opportunities for competition are among the means to achieve this goal. 0000087266 00000 n 0000068253 00000 n [46] On 12 August 2019, ULA submitted Vulcan Centaur for phase 2 of the USAF's launch services competition. 2762 0 obj <> endobj stream mimics the EELV 157.5 cm (62.01 in) Standard Interface Plane. xXn8+84 3m s?0d)!#fDQb-U!~$?ORR /p_)'a}^vh#|Z8+j-v$2c{\u>y-_{ZVV%mr|u|~/a& d0S&/SJig=0QtN&?iHpzje1$Zu>)4{^D)%g/(M%@%@^t`gGe6>a409$"e FA/|W z>q5.~iQXwID:!c 0000101481 00000 n Up to five solid rocket boosters can be added to augment performance. endobj [ /ICCBased 12 0 R ] endobj hs2z\nLA"Sdr%,lt endstream 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. endobj Development is defined as all activities from initial concept up to, but not including, production.

SpaceX bid the existing launch vehicles of Falcon 9 and Falcon Heavy, while Blue Origin was expected to bid New Glenn, ULA bid Vulcan Centaur, and NGIS's bid status was not reported.

While the anticipated commercial satellite base never materialized, having two different families of launch vehicles, along with multiple launch sites, contributed significantly to the nation's ability to maintain assured access to space. 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. The EELV program would maintain current mass-to-orbit capability while increasing launch rate and decreasing costs. 13 0 obj Abstract. Thompson.

Development includes all efforts leading up to and including EELV certification (and the validation of all NRE work) to meet the full range of EELV mass-to-orbit requirements The ELC contract, unlike other payments that the Air Force makes to ULA for launch services, subsidizes costs not directly related to the launch-vehicle hardware, including the depreciation of ULAs launch vehicles and infrastructure. 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. 1a-,,3o WYLd ,/HHVYNE^IUAQM]OGK\H[W&?'#/+/P3KrxTDl\BJX|jbRdtLQn~qIN^AvZizaFfVCYumUcEkSe}KysM]&On;,Z2}sl +7^j[Xcm,?p._.
