The Bonaventure-type was a class of Earth starships that was in service several decades prior to the 2260s.
A vessel of this class, the Bonaventure was the first ship to have warp drive installed. She was lost on her third mission in the Delta Triangle. (TAS: "The Time Trap")
Ships of the class
- Bonaventure (10281NCC)
Star Trek: Star Charts gives the year the Bonaventure was lost in the Delta Triangle as 2079. This date would be consistent with the fact that a Human female was a member of the Elysian Council where everyone was stated to be several centuries old.
Although the Star Trek Spaceflight Chronology depicts this class with a totally different appearance, it states this ship type is called the Cochrane-class cruiser.
