The EELV was expected handle the bulk of the U.S. government's launch requirements after the year 2000 and was also expected to be used for commercial applications. 0000010525 00000 n Development includes all efforts leading up to and including EELV certification (and the validation of all NRE work) to meet the full range of EELV mass-to-orbit requirements Program cost savings are achieved through operability improvements such as the use of common components and infrastructure, a standard payload interface, standardized launch pads and reduced on-pad processing; and acquisition improvements such as launch vehicle block buys. The ESPAStar platform leverages the available mass margin from any EELV launch to provide an affordable path to space for payloads. ?fA(4 F 1@DCPog|yReAZirIrj{*0X}0b{37Vl [mvK7!,ubg-Yj0S(.rIW~,vMJro 8>-\8~-Yw0z UP2^PoDAzuEu;*YRs.KA=^>l=bLe*qV&y.vt%?k7MI(x8 zluC m^"4~b7 xBHNxZ9RRJhkL1hV0 LHJ9KDv"iE^p!+X$(/MDP_dP =|>hPHICt4B@n#,sqBGFY!u&i-dTr2e$'bWv7BiT|nT^F)U9K,rN0bi\2tR0,; Yz{:|*sO=c>z+Mf2BB.4Y!KRcW /*@N]\BN\#`"H`~ez18G&,\0Npd}o$euJ qf3y,.$v=mFWU>f(, 0000058657 00000 n As with the Delta IV, either a 4m or 5m fairing is used to shroud the payload, and vehicles are defined by the number of solids and the size of the payload fairing.

Up to five Aerojet Rocketdyne Graphite-Epoxy Motor solid rocket boosters can be added to increase vehicle performance, and two diameters of payload fairing are available.

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). Delta IV CBCs and DCSSs are integrated horizontally before being transported to the launchpad. 0000016479 00000 n If that was the case, then the Air Force will have developed a new family of launch vehicles that would be primarily used only for national security payloads, resulting in higher overhead costs to DoD, while missing an opportunity to maximize the competitive posture of US industry.
