The Arvak class transport is the fleet backbone of the Interstellar Transit Authority. A relatively short range transport designed for hauling humans and cargo from station to station, the Arvak type is solid, reliable, and a common sight in docking rings and bays all over known space.

Heirotus founder Brandon James contracted a range-extended Arvak (ITA 27945A “Clyde”) from the ITA in order to rendezvous with MBO-1 near Helios. At the time, Heirotus space assets were limited – it was, simply, the first available spacecraft.
