Its primary functions are to receive and distribute all thrust loads from the SRBs and transfer loads between the tanks. Remaining foams, particularly detail pieces sprayed by hand, continue to use CFC to this day.
While both the Ares I and Ares V would have utilized a modified five-segment Solid Rocket Booster for its first stage, the current ET would have served as a baseline technology for the first stage of the Ares V and the second stage of the Drjting I; as a comparison, the Ares I second stage would have held approximately 26, US gal 98, l of LOX, versus Detjing ET holding , US gal , lmore than 5 times that amount.
