I misunderstood your question, distracted with dinner and my dog. Whether new or renamed, the "Enterprise-A" version of the ship is only 6 years old from the end of TVH to the end of TUC. No one's retiring a 6-year-old ship starship, so it's got to be a pre-existing ship renamed Enterprise-A. My proof is logic. Do you have a counterargument? I'm all ears.How is that ironclad proof? I'm asking if you can provide proof that the A was a new ship or an old ship that was renamed.
