Skyroller

The Skyroller is the personal starship of Orion Pax/Optimus Prime in the post-war era. It's not especially large or fast.

IDW Generation 1 continuity
According to Sky Lynx, the Skyroller was acquired by Optimus Prime on Codiscin One.

After abandoning the identity of Optimus Prime, Orion Pax left Cybertron on the Skyroller. During his time teamed up with Hardhead, Wheelie, and Garnak, the ship was hidden under a ghost shield on top of their larger ship, the Ark-27. Following the destruction of the Ark-27 on Gorlam Prime, Orion Pax revealed its presence so they could flee the doomed planet. Though the Skyroller ' s engines weren't powerful enough to escape the gravitational pull of Gorlam Prime's collapse, Orion was able to dock with the newly arrived Lost Light which brought him and his crew to safety.

While Orion Pax and a small team ventured into the Dead Universe, Garnak and Wheelie hung out on the Skyroller nearby in space, to help guide Pax back. Six months later, after retaking his title, Optimus Prime brought the Skyroller with him to Earth on board the Ark-7. Seeking a personal and uninterrupted chat with Alpha Trion, he used the ship to take Trion to the moon. He then departed the Ark-7 with the ship and flew it back to Cybertron.

After Optimus Prime returned to Earth via space bridge and got involved in a battle in Shanghai, Aileron took the same bridge back to Cybertron and fetched the Skyroller, which she flew back through the portal to Earth. It was employed to evacuate both combatants and the space bridge itself, traveling first to Earth Defense Command's HQ and then to Thundercracker's homestead. It was in the Skyroller that Optimus Prime and Jetfire received an ominous transmission from the Lost Light crew. Without a proper headquarters, the Autobots spent their time on Earth constantly on the move on board the Skyroller and Sky Lynx.
