Delta IV CBCs and DCSSs are integrated horizontally before being transported to the launchpad. The primary goal remains 100% mission success while incentivizing cost reductions. 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.

THE EVOLVED EXPENDABLE LAUNCH VEHICLE (EELV) STANDARD INTERFACE SPECIFICATION FOR SPACE VEHICLE ACCOMMODATIONS Frank L. Knight. In October 2018, the USAF awarded development funding to ULA, NGIS, and Blue Origin to further the design of their rockets before a subsequent competition for award to build the launch vehicles. As of 2019, these launch vehicles were the primary methods for launching U.S. military satellites, along with the Falcon 9 developed by SpaceX. Steady production rates, long-term commitments and opportunities for competition are among the means to achieve this goal. Reducing the cost of launches and ensuring national access to space were the two main goals of the USAF space launch/EELV program. ULA is expected to handle 60 percent of the launches while SpaceX will handle 40 percent of the launches over the five-year period. After a two-year solicitation and competition process in 20182020, in August 2020 the USSF selected SpaceX (F9 and FH) and ULA's yet-to-be-certified Vulcan Centaur to supply US military launch requirements in 20222027. 0000004305 00000 n 120 0 obj 2762 0 obj <> endobj The ESPAStar platform leverages the available mass margin from any EELV launch to provide an affordable path to space for payloads. 637 0 obj <> endobj 19 0 obj hbbd```b`` d#XD 0000005030 00000 n Search 209,668,378 papers from all fields of science .
