The UEA Sirius is the UEA Canopus’ sister ship. Commissioned and launched before the Canopus, there are some minor differences between her and her sister. The Sirius’ duties have left her on assignment in Sol Sector. She may be encountered later in the story, although you’ll never be flying off of her. But for those of you who want to mix things up a bit, the Sirius is available to be launched from in the Simulator. The screenshots below are from a generated simulator mission.
