The class was put into service some time in the 22nd century. In the year 2154 ships of this class defended Andoria from invasion by the Vulcan High Command and later participated in the hunt for the Romulan Drone Ship. (ENT episodes: "Kir'Shara", "United")
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. Their primary role, along with most of the Andorian ships, was the defense of Federation territory.
In 2165, three Sevaijen class light cruisers 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. One of the vessels was the USS Kinaph, which was commissioned by the Arkenites, a former Andorian subject race, upon their admission into the Federation.
