The USS Strata was a Federation geo-terraforming vessel in service in the mid-24th century under the command of Captain Jason Stone. Doctor Martin Rackham was the starship's Chief Medical Officer. The Strata was the first assignment of the then Ensign Chu'lak in 2355. (DS9: "Field of Fire")
- The Strata was only briefly seen in a computer display, and wasn't mentioned in dialog. The name is perhaps an in-joke reference to the Terry Pratchett novel of the same name, which was also concerned with geo-terraforming (of a sort).
