The Atlas V family uses a Russian RD-180 to power the first stage Common Core Booster. 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. 0000002426 00000 n @(l(MW a 67E1efWmh8s`e3XY|t+$8f`~!Af6 Dy3 That strategy was designed to (1) .

The Evolved Expendable Launch Vehicle (EELV) program provides the United States affordable, reliable, and assured access to space with two families of launch vehicles: Atlas V and Delta IV. 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. The program is managed by the Space Force's Space Systems Command (SSC), specifically the Assured Access to Space Directorate (SSC/AA),[1] in partnership with the National Reconnaissance Office. %%EOF Although additional new entrants may be able to compete in the future, it is unlikely that others will be ready to compete before Phase 2. The approach continues procurement of launch services and launch capability from ULA for the next several years but provides for a full and open competitive environment for any alternative sources as soon as they are certified. The Pratt & Whitney Rocketdyne -built RS-68, a liquid hydrogen/liquid oxygen engine that produces 663,000 lbs of liftoff thrust, powers the first stage. [16] Each company has a 50% stake in ULA. [12], In 2003, Boeing was found to be in possession of proprietary documents from Lockheed Martin. The first Heavy vehicle (demo) was launched in December 2004. As of that time, Vulcan Centaur was on track for a 2021 launch. [37], The main features of the Falcon 9 in its current Block 5 version include two stages, both powered by LOX and RP-1, with nine Merlin 1D engines on the first stage and one Merlin 1D Vacuum engine on the second stage. Development is defined as all activities from initial concept up to, but not including, production. 0000461158 00000 n ULA has a big factory down in Decatur, Alabama. In paying ULA for such fixed launch costs and executing the EELV program under a cost-plus contract, the DoD has reimbursed ULA for allowable, reasonable, and allocable costs for its launches, while requiring ULA to reimburse it on a per-launch basis for launches that ULA sells to its non-DoD customers. [38] This launcher features a reusable first stage and fairings, which lowers the cost per mission. << /Length 5 0 R /Filter /FlateDecode >> It uses 457,295 lbs (207,425 kg) of liquid oxygen and 169,008 lbs (76,660 kg) RP-1 rocket fuel propellants.
