I know the brand/studio reasons, but all I can come up with for in-setting lore reason is that Mirandas require less resources/crew/maintenance, but it still seems like a sharp contrast between the service lives of both ships where, as far as I can tell, the Excelsior-class may have required more resources/crew/maintenance and that judging by size and a history of jankiness alone (I love the ship, I really do, but it’s still an in-setting thing) and even the Constellation seemed to be kept around at least a little longer than the Constitution.
Anyone got any sources about this that make it feel justified besides the studio/suits deciding “we don’t want audiences to confuse anything on screen for the TMP refit” ?
Maybe it’s just that there were fewer of them and their captains kept destroying them
If that was the reason, Deep Space 9’s lost ship count alone would have ended the Miranda-class.
