[20], The USAF signed a contract at that time with SpaceX for two launches in 2014 and 2015 to serve as proving flights to support the certification process for the Falcon 9 v1.1 and Falcon Heavy. The goal was the creation of a cost-efficient and reliable family (or families) of "right size" spacelifters based on standardized fairings, liquid core vehicles, upper stages, and solid rockets. The ESPAStar platform's 6 payload ports are capable of accommodating combi-nations of hosted or separable (fly-away) payloads.

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. [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. [46] As of 2019, Blue Origin expected a first launch of New Glenn in 2021. %PDF-1.3 The payload interface at each port has been A Standard Payload Interface bus was also proposed as a way to save money and improve efficiency. {,M?TSwjj:2U|=ney(ymjvkeY&AeZDuL2 M#oWX~s iAzj]:a[Fd U?Vi5p5Zq,9,bZ/@,%, 6`#@)4I7,nCsSXDiAG'By"yeGy)h\s1{.D._"e-`uM67h2I ]_R)4I}I ? ;mnf4fb3/!s}Wz#I/MeFg_$ob$bOR JDs5~7^U.BV*p3]2j,BBR3Pq2,LnVL{gLj}U;g;bqGQY7C85V7y3fi=fp"n0+ddobk 0000003719 00000 n Table 2 - Quasi-Static Load Factors - "Paper Session II-C - The Evolved Expendable Launch Vehicle (EELV) Standard Interface Specification For Space Vehicle Accommodations" Skip to search form Skip to main content Skip to account menu. << /Type /Page /Parent 3 0 R /Resources 6 0 R /Contents 4 0 R /MediaBox [0 0 612 792] trailer for GPS III Launch Services . 0000076318 00000 n 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). [3][4], On 1 March 2019, the program name was changed from EELV to National Security Space Launch (NSSL) to better reflect the growing commercial launch market and the changing nature of launch contracts, including the potential for reusable launch vehicles. 15 0 obj Program cost savings are achieved through operability improvements such as the use of common components and infrastructure, a standard payload interface, standardized launch pads and reduced on-pad processing; and acquisition improvements such as launch vehicle block buys. An Atlas V XYZ will have a 4.2-or-5.4-meter (14 or 18ft) diameter payload fairing, Y solid rocket boosters (0-5), and Z RL-10's on the Centaur upper stage (1-2). 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. 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. 0000001979 00000 n Evolved Expendable Launch Vehicle (EELV) Standard Interface Specification (SIS) Air Force Instruction 10-1202, Space Test Program Management Air Force Instruction 10-1202_AFSPCSUP, Space Test Program Management AFSPCI 13-1213, Launch Scheduling and Forecasting Procedures 1.5.2 Department of Defense Documents Semantic Scholar's Logo. As of that time, Vulcan Centaur was on track for a 2021 launch. a new EELV acquisition strategy in November 2011, revising it in 2013. Launch performance can be augmented by adding either two or four solid rocket motors. Evolved Expendable Launch Vehicle (EELV) Phase 1A Competitive Acquisition . Two providers were to be selected to launch spacecraft to a number of reference orbits. EELV was important not only to reducing the launch costs of the Department of Defense, but also to the continued world-wide competitiveness of the US commercial launch industry. The ESPAStar platform leverages the available mass margin from any EELV launch to provide an affordable path to space for payloads. Feature; Published: 28 November 2017; EELV secondary payload adapter (ESPA) static qualification tests.

[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. 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. 0000001790 00000 n 5 0 obj ULA stated it did not have any Atlas engines available to bid in order to submit a timely proposal. 0000005030 00000 n 0000003519 00000 n In early 2016 the incumbent contractor, United Launch Alliance (ULA), decided not to compete for the first competitive launch opportunity under Phase 1A of EELV, which provides for the launch of a GPS III satellite. 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. [8] Some of the reasons why assured access to space is a priority for the United States are stated in National Presidential Directive Number 40, which reads: Access to space through U.S. space transportation capabilities is essential to: The United States, therefore, must maintain robust, responsive, and resilient U.S. space transportation capabilities to assure access to space. /TT4 11 0 R >> >> On this Wikipedia the language links are at the top of the page across from the article title. Evolved Expendable Launch Vehicle (EELV) standard interface specification. 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. The USAF and United States Space Force (USSF) plan to use the next generation NSSL launch vehicles until at least 2030.[31]. Delta IV Medium flew with two or four SRBs on a single Common Booster Core. As an example, an Atlas V 551 has a 5.4m payload fairing, 5 SRBs, and 1 RL-10.[35]. Up to five solid rocket boosters can be added to augment performance. As of 2019, these launch vehicles were the primary methods for launching U.S. military satellites, along with the Falcon 9 developed by SpaceX. 4 0 obj 0000002358 00000 n The RSS is offered only onEvolved Expendable Launch Vehicle (EELV) LVs certified to launch National Security Space missions; hence, APLs must not violate EELV requirements documented in the EELV Standard Interface Specification (SIS) and/or System Performance Requirement Document (SPRD).

The EELV competition was expected to produce the next generation of launch vehicles to replace all medium to heavy launchers, Lockheed Martin's Atlas, Titan II and Titan IV series, and McDonnell Douglas's Delta series, with a single family of vehicles capable of launching medium and heavy payloads into orbit at a significantly lower cost. 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. [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. [46] OmegA was a rocket design with two main solid stages, a cryogenic upper stage, and the possibility of additional solid-rocket strap-on boosters. In August 2021, ULA announced that Atlas V would be retired, and all 29 remaining launches had been sold. [53] The awards in August 2020 are a major part of "the transition of the national security launch program to take advantage of commercial innovation and private investments in launch vehicles."[47].
