Background information Edit
The Star Trek Encyclopedia (4th ed., vol. 1, p. 374) described the Intrepid as the prototype for the Intrepid-class starship. It was assumed by the authors of this reference work that this was the third Federation Starfleet ship named Intrepid.
The Intrepid was also mentioned in Articles of the Federation.
