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). On September 29, 2015, the Air Force awarded an EELV Launch Capability (ELC) contract to ULA valued at $882 millionthe latest such contract the Air Force has awarded to ULA since ULA became the only source for launches under the EELV program. [14] The USAF moved 7 launches from Delta IV to Atlas V.[15] To end litigation and competition for a limited market, both companies agreed to form the United Launch Alliance (ULA) joint venture. The payload interface at each port has been standardized, allowing for hosted and separable payload interchangeability, late payload integration and manifest changes. }, Page last modified: {!Kd#5:#[T$FhTs;*(Ai((4N|radRbt!BHx2eq(*xiTxa$m|+Id99uLA@(C!#Oro;{N4"#. A1vjp zN6p\W pG@ stream In addition to manufacturing the launch vehicles, ULA also maintains space launch complexes at Cape Canaveral Air Force Station, Fla, and Vandenberg SpaceForce Base, Calif. RFP F04701-97-R-0008 19 June 1998 ii Photo Credit: U.S. Space Force. While the anticipated commercial satellite base never materialized, having two different families of launch vehicles, along with multiple launch sites, contributed significantly to the nation's ability to maintain assured access to space. nG +D,@g%ZKh?RgO>52orjm*R2C}H6m5W0_/om>+pZ}. The EELV program would maintain current mass-to-orbit capability while increasing launch rate and decreasing costs. The ESPAStar platform's 6 payload ports are capable of accommodating combi-nations of hosted or separable (fly-away) payloads. Thats Defining Possible. It uses 457,295 lbs (207,425 kg) of liquid oxygen and 169,008 lbs (76,660 kg) RP-1 rocket fuel propellants. [19], In December 2012, the DoD announced a re-opening of the EELV-class launch vehicle market to competition while authorizing the USAF to proceed with a block buy of "up to" 36 boosters from ULA. 7 0 obj RFP F04701-97-R-0008 19 June 1998 ii This page intentionally left blank. The contractor was standardizing payload interfaces, launch pads, and infrastructure so that all configurations of each contractor's EELV family can be launched from the same pad and payloads can be interchanged between vehicles in the same class (i.e., medium, intermediate, or heavy). 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. The payload interface at each port has been standardized, allowing for hosted and separable payload interchangeability, late payload integration and manifest changes. APL requirements are not addressed in the SIS but their Along with the award of two development agreements, the total amount was more than $3 billion. [35], A three-digit (XYZ) naming convention is used for the Atlas V configuration identification. O*?f`gC/O+FFGGz)~wgbk?J9mdwi?cOO?w| x&mf [32] The DCSS had 4m diameter and 5m diameter versions, with matching diameter payload fairings. Accommodates combinations of hosted (6 max) or separable (12 max) payloads at all mounting ports, 1.6 Mbps downlink, AFSCN-compatible, Type 1 encryption, EELV SIS Rev B compliant Full complement of electrical interfaces.
