This being a very long tread if someone could enlighten me I would be grateful. For those who think NCC-1701-A was a new ship, how can we explain her decommissioning only after eight years? This is one critical fact that makes me doubt she was a new ship...
In the final battle sequence of STVI, the Enterprise takes a serious pounding from Chang's BOP. It's beaten to the point of collapsed shields, and a torpedo punches a hole completely through the primary hull. Maybe the Starfleet engineers did a cost-benefit analysis and, coupled with Kirk retiring, decided "Just scrap it and go with the Excelsior class!"
