Well in the case of Kirk's ships, both came back with heavy battle damage.
It's not as if the ST4 Saratoga
especially enjoyed her meeting with the Whale Probe, either...
Then again, we don't know everything about the relative ages of the ship designs or individual ships involved. Perhaps none of the Mirandas
were refits of 2240s-vintage starships, but brand new things from the 2280s instead, despite sporting registry numbers in a range we already witnessed in the 2260s in that "Court Martial" wall chart?
