“Life forms. You precious little lifeforms. You tiny little lifeforms. Where are you?”
- Lt. Cmdr Data, Star Trek: Generations
At least the OG 1701 got a good lifespan - it was no Miranda, but 40 years is great for an Enterprise.
The decommissioning of the A seemed a bit premature, though, considering it was a new ship that was relatively salvageable. Maybe its battle damage was just too much and that’s why it was given to the museum. Alternatively, the A was originally a different Constitution class undergoing a refit was was already quite old by Undiscovered country.
There’s a good chance the B lasted a long time too, though there’s no canon source to its demise, only that it’s not in the fleet museum.
Another update (12/27/2024): In 1x07:”Much Ado About Boimler”, there are kids aboard the Rubidoux, which suggests at least some Cali-class vessels have children.
