The Vulcan is a refuel, rearm and repair spacecraft manufactured by Aegis Dynamics for the United Empire of Earth (UEE) military. First launched in SEY 2594, it was commissioned by the UEE Navy after they requested proposals for a medium-sized support spacecraft. After a successful trial period, the UEEN promoted the ship into active service as its standard front-line support ship during such conflicts as the Second Tevarin War (2603 - 2610) and the Siege of Tiber (2732 - 2736). Since its introduction, it has been upgraded many times, and civilian models of the Vulcan have been offered to the public since the early 27th century.
