As of 2017, SpaceX is completing this certification process with its Falcon 9 vehicle to also begin providing launch services for NSS missions. The second stage (known as Centaur) is powered by the RL-10A engine. The platform is optimized for GEO missions, but is adaptable for LEO and MEO missions. National Security Space Launch ( NSSL) formerly Evolved Expendable Launch Vehicle (EELV) from 1994 to 2019 is a program of the United States Space Force (USSF) intended to assure access to space for United States Department of Defense and other United States government payloads. 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. 0 As of that time, Vulcan Centaur was on track for a 2021 launch.

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.

The EELV program would maintain current mass-to-orbit capability while increasing launch rate and decreasing costs. 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. 0000001182 00000 n Each of the bids included a variety of concepts.

As of September 2019, it has two manifested classified national security flights for the USAF in 2021.[43][44][45]. 6 0 obj stream [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. 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. Boeing initially proposed using the RS-25 Space Shuttle main engine. hb```|+a1b0K5IiJs!C}D&m%[Xuddtu p|6:O3|3v)-F'M1*vm^b1:JeSzr60v0ht00t@0Gb0$cDHG Abt:2{$8naMeJC1kYDHn)_2u hH1=l for GPS III Launch Services . [49] In the event, no phase 2 funding from the US government was forthcoming after August 2020 when ULA Vulcan and SpaceX were selected by the Air Force. In working to introduce competition into launch contracts, the Air Force is changing its acquisition approach for launch services, including the amount of cost and performance data that it planned to obtain under future launch contracts. 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. 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). 0000010525 00000 n In 1998, when it appeared the growth in the commercial satellite industry would be able to sustain two providers of launch services, the Air Force decided to award contracts to both Boeing and Lockheed Martin for their respective launch capabilities.
