[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. [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. 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. 0000017080 00000 n 0000082556 00000 n 0000006880 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). 0000068216 00000 n [35], A three-digit (XYZ) naming convention is used for the Atlas V configuration identification. 0000004305 00000 n This page was last edited on 19 February 2023, at 18:43. This would be difficult to achieve since projections showed that the EELV would not be able to meet the requirements of as much as 42 percent of the estimated commercial market. 0000461158 00000 n 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. [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. The procedure and process for development, control, and maintenance is the same for ICDs and ISs. It uses 457,295 lbs (207,425 kg) of liquid oxygen and 169,008 lbs (76,660 kg) RP-1 rocket fuel propellants. It has been certified for the NSSL program after the STP-2 launch completed on 25 June 2019, as confirmed by the commander of the Air Force Space and Missile Systems Center, Lt. Gen. . 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. Two providers were to be selected to launch spacecraft to a number of reference orbits. %PDF-1.3 The payload interface at each port has been standardized, allowing for hosted and separable payload interchangeability, late payload integration and manifest changes. [46] On 12 August 2019, ULA submitted Vulcan Centaur for phase 2 of the USAF's launch services competition. We encourage you to use one of these browsers for the best experience. [39], GPS-IIIA USA-289 was the first NSSL-type B5 Falcon 9 launch. [14] The USAF moved 7 launches from Delta IV to Atlas V.[15] To end litigation and competition for a limited market, both companies agreed to form the United Launch Alliance (ULA) joint venture.

Up to five solid rocket boosters can be added to augment performance. 1. 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. EELV Standard Interface Specification - Version 6.0 2. [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.
