An kuma inganta wuraren ajiyar ruwa na hydrogen da ruwa na oxygen a Launch Pad 41 don ɗaukar babban matakin saman Centaur, wanda zai tashi a kan rokar Vulcan.
Sabuwar rokar Vulcan ta saman matakin Centaur 5 tana da diamita na ƙafa 17.7 (mita 5.4), fiye da faɗin Centaur 3 na saman matakin Atlas 5 sau biyu.
