The US Space Force (USSF) plans 3034 launches during these five fiscal years. 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. % 0 Abstract. 2612 [36] As of 10November2022[update], 19 launches remain. Standard payload interfaces were touted as another way to save money and improve efficiency, though success in that area remained to be seen. As of 2019, these launch vehicles were the primary methods for launching U.S. military satellites, along with the Falcon 9 developed by SpaceX. These load factors, as shown in Table 1, represent a set of accelerations that Announced performance requirements include:[29][30]. 0000004305 00000 n 0000004106 00000 n Category A payloads fit within a 4m diameter payload envelope, category B payloads fit within a 5m diameter payload envelope, and category C payloads require an extended 5m diameter envelope. [16] Each company has a 50% stake in ULA. The USAF began the EELV program in 1994, following many years of government-funded studies into improved systems and architecture.

[12] Boeing was awarded a contract for 19 out of the 28 launches; Lockheed Martin was awarded a contract for the other 9. -2- 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. <>stream [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]. 0000058694 00000 n 4 The NSSL system includes launch vehicles, launch capability, a standard payload interface, support systems, mission integration (includes mission unique requirements), flight instrumentation and range interfaces . << /Length 5 0 R /Filter /FlateDecode >> New ICD Revisions in Development 8/22/2022: UPREVISIONS RELEASED [7A\SwBOK/X/_Q>QG[ `Aaac#*Z;8cq>[&IIMST`kh&45YYF9=X_,,S-,Y)YXmk]c}jc-v};]N"&1=xtv(}'{'IY) -rqr.d._xpUZMvm=+KG^WWbj>:>>>v}/avO8 120 0 obj Compliance with Standard Interface Specification (SIS) - Defines the standard interface between the payload and the launch system.

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. 0000015937 00000 n [25][26] The USAF certified the Falcon 9 in May 2015,[27] and in 2016 SpaceX won a contract under the EELV program to launch a GPS Block III satellite payload to MEO. The FY 2016 NDAA recognized that a small number of Russian engines could be needed to ensure a near-term competitive environment. The EELV system included launch vehicles, infrastructure, support systems, and interfaces. 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.
