I'm curious what they intend to do once the reusable first stage program gets going and launch costs drop even further. ULA is working on reusability of at least the engine in its vulcan rockets that will replace Atlas and Delta in 2019: https://spaceflightnow.com/2015/04/13/ula-unveils-its-future-with-the-vulcan-rocket-family/ https://spaceflightnow.com/2015/04/13/ula-unveils-its-future... the plan is for vulcan to cost about 50% of an atlas V... so about 80-100m
