They originally planned to have three types of Orion flying, each on Ares I. Type I would carry crew. Type II would basically be a cargo version of the first one (like Crew Dragon V2 vs Cargo Dragon V2) while Type III would put a Cygnus on the Orion service module.

Orion was supposed to fly like 4-6 times a year. There were 3 versions of Orion planned, actually.
1) Crew Transport Orion: Pretty much Orion as we all know. It was supposed to fly to the ISS twice a year for crew rotations, as well as go to the moon and whatnot.
2) Cargo Orion: Think of it like a bigger version of Dragon. This one used the crew capsule of the Crew Orion but filled it with cargo. It was supposed to fly to the ISS twice pert year.
3) Vacuum Cargo Orion: This one was designed to act like the Dragon’s trunk. It used the regular Orion’s service module, but instead replaced the capsule with an expendable cargo carrier that could be depressurized for stuff like station components.
