A possible commercial launch option for Orion using Falcon Heavy, as apparently proposed by SpaceX and now under study by NASA.
Given the schedule limitations, I assume if this happens at all (unlikely) it'd have to use reflown boosters. Whether legs or grid fins are included would depend on the mission design. A LEO-only mission, or lunar with Earth-orbit rendezvous, would allow full recovery, but a direct TLI launch requires full expendability.
Delta IV Heavy alternate version coming soon.
