A Bonaventure-class vessel
The Bonaventure class was a class of Starfleet starship that was brought into service after the NX and related classes. It marked a radical change in starship design, described as being the equivalent leap as the original Phoenix to the NX-class.
The starship registered NCC-1000 was a Bonaventure-class vessel. (ST reference: Ships of the Line)
These Ships were on the drawing boards as of 2163 and would eventually enter service by the 2190s.(ENT - Rise of the Federation novel: A Choice of Futures)
