[Star Trek] Archer had an Enterprise. Then Kirk had an Enterprise. Then they built Enterprise-A. Why wasn't Kirk's vessel Enterprise A?

And why, when Scotty told the holodeck to show him the bridge of the Enterprise, "...no bloody A, B, C, or D" did the computer show him Kirk's vessel, and not Archer's? Also, the computer said there were only FIVE vessels with that name. Archer's Enterprise, Kirk's, and A-D make six.

Archer's Enterprise was the NX-01 Enterprise, and did not start its life as a Federation ship, bug as a part of United Earths Starfleet. All subsequent Enterprises had the NCC-1701 designation and were Federation vessels.
