I remember having a discussion here on this subject some time ago.
There was a theory that it is the Yorktown
, briefly mentioned in IV. This can also explain the system failures the Enterprise
is facing in V; suggesting the ship's computers were still affected by the probe's wave. My only issue with that is, I find it weird that an entire crew would be reassigned and the ship renamed, all for Kirk and crew's benefit, but I don't know how the military works in that sense, so. But it may also explain why that Enterprise
had the shortest lifespan, since she was decommissioned in VI.
But even with the decommissioning of the Enterprise-A
in VI, I wonder if it was about that time the Constitution class ships were taken out of service.
