it will be filled with insulated material.
The nested configuration of the propellant tanks with the upper tank dome inverted seems to have a better advantage in terms of mass saving. How many launch vehicles have been using such tank configurations? I knew about ares-V that never flew. Why is such a configuration neglected? or am i missing something?

or for Centaur 5/ACES on Vulcan, or it might not.
