The class was put into service some time in the 22nd century by the Imperial Guard, and when the United Federation of Planets was formed and the member nation's space services were integrated these vessels were transferred over to Starfleet authority.
In the year 2165, two Ilthirin class couriers were assigned to Captain Malcolm Reed's task force, which was charged with learning everything they could about the Ware and their creators and stopping them. Because of their fast speed, they were charged with supplying the USS Pioneer with spare parts, medical relief and transport and to serve as subspace relays between Pioneer and the task force.
