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). Launch performance can be augmented by adding either two or four solid rocket motors. hs2z\nLA"Sdr%,lt ULA also asserted that the Phase 1A launch is basically a lowest price, technically acceptable competition, unsuitable for launch contracts" A1vjp zN6p\W pG@ 0000015937 00000 n The FY 2016 NDAA recognized that a small number of Russian engines could be needed to ensure a near-term competitive environment. . [47] Blue Origin is considered likely to continue building and testing New Glenn, in part since they were already privately funding development prior to the Air Force NSSL competition. The Delta IV Medium, Medium-Plus and Heavy configurations are evolved from flight proven Delta II and Delta III systems while incorporating the latest technology into a family of vehicles maximizing the use of common hardware. This could include full development of a new launch system or modifications to an existing launch system, including launch infrastructure.

ULA stated it did not have any Atlas engines available to bid in order to submit a timely proposal. May 2016 : Space and Missile Systems Center . 12 0 obj The EELV program was initiated in 1994 and planned to be a "rolling-downselect" of launch vehicle providers from four to one. 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. 0000027829 00000 n %PDF-1.6 % Making space accessible. 0000006582 00000 n [39], GPS-IIIA USA-289 was the first NSSL-type B5 Falcon 9 launch.

[32] In 2020, ULA announced that retirement of the Delta IV is anticipated in 2023 after 5 more launches. Northrop Grummans ESPAStar platform provides a modular, cost-effective and highly capable infrastructure resource for hosting technology development and operational payloads. [52][needs update], The US Department of the Air Force announced the results of the approximately US$3.5 billion National Security Space Launch Phase 2 Launch Service Procurement on 7 August 2020. The procedure and process for development, control, and maintenance is the same for ICDs and ISs. Blue Origin also filed a pre-award protest of the request for proposal arguing that the requirements were ambiguous. The Atlas V family uses a Russian RD-180 to power the first stage Common Core Booster.

EELV STANDARD INTERFACE SPECIFICATION VERSION 5.0. Delta IV's inaugural flight was marked by the successful launch of a commercial satellite on a Medium-Plus (4,2) in November 2002. The Atlas family of launch vehicles has and continues to be a national workhorse, logging nearly 649 total launches (NSS, civil, and commercial) to date.

Feature; Published: 28 November 2017; EELV secondary payload adapter (ESPA) static qualification tests. With multiple launch vehicle configurations and launch sites on both coasts of the U.S., EELV has a proven track record of success, demonstrating unprecedented reliability with 106 successful launches since 2002. - A final check of specifications will be conducted prior to launch. A Standard Payload Interface bus was also proposed as a way to save money and improve efficiency. Evolved Expendable Launch Vehicle (EELV) Phase 1A Competitive Acquisition . 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. 0000002686 00000 n 27 33 [36] As of 10November2022[update], 19 launches remain. x[n$ }hIY 7g8@/U}f9MHy^Z^~|^|TWmo<4c5UX|.Gqjs[6oc?y~x,D? 2 0 obj - 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. trailer <<8D9465B782A042F99BA9A4986B1592D1>]/Prev 881083>> startxref 0 %%EOF 59 0 obj <>stream The second stage (known as Centaur) is powered by the RL-10A engine. 0000006880 00000 n .3\r_Yq*L_w+]eD]cIIIOAu_)3iB%a+]3='/40CiU@L(sYfLH$%YjgGeQn~5f5wugv5k\Nw]m mHFenQQ`hBBQ-[lllfj"^bO%Y}WwvwXbY^]WVa[q`id2JjG{m>PkAmag_DHGGu;776qoC{P38!9-?|gK9w~B:Wt>^rUg9];}}_~imp}]/}.{^=}^?z8hc' << /Type /Page /Parent 3 0 R /Resources 6 0 R /Contents 4 0 R /MediaBox [0 0 612 792] The ESPAStar platform's 6 payload ports are capable of accommodating combi-nations of hosted or separable (fly-away) payloads. hb```,l? These launch vehicles provide critical spacelift capability to support Department of Defense and other National Security missions (together known as National Security Space (NSS) missions). 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. <<1FA29D3E1AADB2110A00D0FE946CFD7F>]/Prev 340978>> 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. trailer The EELV was expected handle the bulk of the U.S. government's launch requirements after the year 2000 and was also expected to be used for commercial applications. These launch system investments include efforts required to complete the transition off non-allied engines and build upon the Air Force's Booster Propulsion Technology Maturation efforts started in early 2015 and the Rocket Propulsion System investments awarded in early 2016. 1a-,,3o WYLd ,/HHVYNE^IUAQM]OGK\H[W&?'#/+/P3KrxTDl\BJX|jbRdtLQn~qIN^AvZizaFfVCYumUcEkSe}KysM]&On;,Z2}sl +7^j[Xcm,?p._.

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. 2612 stream An official website of the United States government, The Atlas V's inaugural flight was marked by the successful launch of a Hotbird-6 commercial satellite, Hosted by Defense Media Activity - WEB.mil. wc/CR6@Vf|N`ObN#C8\'08#9MVk-v^.O@G}&(U!

The ESPAStar platforms six payload ports are capable of accommodating any combination of up to six hosted and 12 separable (fly-away) payloads (maximum one hosted or two separables per port). The Medium & Medium-Plus vehicles use a single Common Booster Core (CBC), while the Heavy variant uses three CBCs. Along with the award of two development agreements, the total amount was more than $3 billion.
