List of unnamed Federation starships of the Merian-class.
Victims of the Burn []
At least six ships of the class were lost to the Burn in c. 3069. When dilithium spontaneously became inert, these vessels lost antimatter containment and exploded. (DIS: "People of Earth")
Sustaining Federation Headquarters (3189)[]
When the USS Discovery first found Federation Headquarters in 3189, at least two Merian-class starships supported the cloaking field. (DIS: "Die Trying")
A ship of this class was also visible on a diagram Fleet Admiral Charles Vance and Lieutenant Audrey Willa were examining when Captain Saru met with them. (DIS: "Scavengers")
Battle at Federation Headquarters[]
Two ships of this class were sustaining the Federation Headquarters cloaking field when Osyraa was able to enter it aboard Discovery. (DIS: "There Is A Tide...") Both later participated in the Battle at Federation Headquarters with Osyraa (commanding Discovery.) At least one was positioned at a safe distance when Discovery detonated their warp core to destroy the Viridian, and was positioned to welcome Discovery back to Federation Headquarters at the culmination of the battle.
