Star Trek: 10 Secrets About The USS Enterprise-G You Need To Know
3. Re-Constituted
The decision to make the ship a Constitution III type was a conscious one. When audiences look back, this makes the final revelation of the series even more sensical.
There are clear parallels in the story of NCC-1701-G to the first time viewers were graced with a new USS Enterprise in the closing minutes of Star Trek IV: The Voyage Home.
If we go by either canon or non-canon lines, the USS Enterprise-A was a renamed ship. Although not mentioned on screen, the USS Yorktown was renamed in honour of Kirk and her crew. Yorktown was almost the original name of the ship back in the 1960s. The 1980s book Mr Scott's Guide to the Enterprise suggested it was called the Ti-Ho before being renamed.
As Terry Matalas has said, the third season acts as an origin story for the G with it appearing alongside the NX-01, the A, D, and F iterations of the namesake at the Fleet Museum and later on Frontier Day.
