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. 0000068216 00000 n VwSX$qjDMjdJpIo.|];"P+ S]^M%f{6x57>Z"}}2)p"B1dKwh[h!t!j)L[C@|}TUaH6hFHTFLV^Y#8g3Tx]!y;Tc^>ME|= 9WTsD. 0000058694 00000 n .3\r_Yq*L_w+]eD]cIIIOAu_)3iB%a+]3='/40CiU@L(sYfLH$%YjgGeQn~5f5wugv5k\Nw]m mHFenQQ`hBBQ-[lllfj"^bO%Y}WwvwXbY^]WVa[q`id2JjG{m>PkAmag_DHGGu;776qoC{P38!9-?|gK9w~B:Wt>^rUg9];}}_~imp}]/}.{^=}^?z8hc' i`zN$KgyHDis+hj^@BV/C4v3bKAj.

Reducing the cost of launches and ensuring national access to space were the two main goals of the USAF space launch/EELV program. 19 0 obj wc/CR6@Vf|N`ObN#C8\'08#9MVk-v^.O@G}&(U!

In August 2021, ULA announced that Atlas V would be retired, and all 29 remaining launches had been sold. 97 24 The Medium & Medium-Plus vehicles use a single Common Booster Core (CBC), while the Heavy variant uses three CBCs. Abstract. That strategy was designed to (1) . SpaceX and ULA were the two vendors selected via the competition to supply launches to the US military in the 20222027 timeframe. [35], A three-digit (XYZ) naming convention is used for the Atlas V configuration identification. This could include full development of a new launch system or modifications to an existing launch system, including launch infrastructure. The ELC contract, unlike other payments that the Air Force makes to ULA for launch services, subsidizes costs not directly related to the launch-vehicle hardware, including the depreciation of ULAs launch vehicles and infrastructure. 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 . With multiple launch vehicle configurations and launch sites on both coasts of the U.S., EELV has a proven track record of success, demonstrating unprecedented reliability with 106 successful launches since 2002. 0000001361 00000 n xXn8+84 3m s?0d)!#fDQb-U!~$?ORR /p_)'a}^vh#|Z8+j-v$2c{\u>y-_{ZVV%mr|u|~/a& d0S&/SJig=0QtN&?iHpzje1$Zu>)4{^D)%g/(M%@%@^t`gGe6>a409$"e FA/|W z>q5.~iQXwID:!c The Delta IV Heavy launch vehicle uses three Common Booster Cores (CBCs) each powered by a Pratt and Whitney Rocketdyne RS-68A engine, a Delta Cryogenic Second Stage 5m (DCSS) powered by an RL10, and a 5m payload fairing. RFP F04701-97-R-0008 19 June 1998 ii This page intentionally left blank. A Standard Payload Interface bus was also proposed as a way to save money and improve efficiency. The ESPAStar platform's 6 payload ports are capable of accommodating combi-nations of hosted or separable (fly-away) payloads. [42] The USAF is working with SpaceX to mature their Falcon Heavy's design. 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. 0000001202 00000 n The payload interface at each port has been standardized, allowing for hosted and separable payload inter-changeability, late payload integration, 637 0 obj El Segundo, California 90245-2808: DISTRIBUTION STATEMENT a: Approved for public..
