The payload interface at each port has been standardized, allowing for hosted and separable payload inter-changeability, late payload integration, The Evolved Expendable Launch Vehicle (EELV) program is managed by the Launch and Range Systems Directorate of the Space and Missile Systems Center (United States Space Command), Los Angeles Air Force Base, Calif. The second stage is powered by the RL-10B engine. c0|_}`pz0 cc4D 7\HCj(I?uf eX_0NcRu1wQ9 T'|>H%Z%*.yXSGc 4_GR+[5> (4'XgVZtL aq[aP/}ARI@PAwO8s .i,@Yf6akrCns!Uu* 4?,20-FKDgLuAp4j$hz~ "=pdsy8&$vHl"nt{ N kMw3ZN=z[aJ a-O z%Ay3CFKV'#3Y5QC(P7oG'Nc7z_`A&Bu0Y@#gn:y"f-Q M;]jDA\Iz$zY_af1 6 @R:#\DY%nsf^I! %%EOF The payload interface at each port has been standardized, allowing for hosted and separable payload interchangeability, late payload integration and manifest changes. hbbd```b`` d#XD On this Wikipedia the language links are at the top of the page across from the article title.
