Did anyone riot when the B only appeared briefly, the C was in just 1 episode, and the J was hypothetical?![]()
The Ent-b was brand new and had its full service awaiting it.
The Ent-C was... on supposedly last mission but it was also destroyed in the battle of Narendra III.
The ENT-D was destroyed under ridiculous circumstance and quite frankly, the saucer was still salvageable, so SF could have towed it back to nearest shipyard, repaired it and give it another galaxy class secondary hull and put it back into active duty (but hey, if SF didn't want to bother, fine... in this particular instance, I can see this happening).
The ENT-E had a distinguished record apparently but no mention of it being critically damaged, or destroyed.
ENT-F was apparently serving for 20 odd years, and then suffers damage and is completely retired?
Something isn't right here. The ENT-E should have gone on for much longer.
UFP ships are supposedly designed to last 200 years. I don't care how much damage a ship takes, you can use replicators and transporters to refresh its internal superstructure every 10 years or so if need be (what was once old has been harvested and turned into brand new - and voila - but again, this would only be necessary if the ship underwent severe strain during its service record), and the USS Lakota proved you can upgrade 80 year old ships with modern hardware to make it on par with modern powerful ships.
Changing a ship so often is utterly wasteful and doesn't make any sense. Unless they are critically damaged beyond repair (which for a society that has replicators and transporters doesn't mean much) there's no need to change a ship every series.
Voyager was decomissioned because of its historic journey through the DQ... and was turned into a museum. That was a PR move if anything else and good for morale, plus the explanation works if you ask me (but on a level I still think it may have been removed from active service way too soon as its still an able/proven vessel).
Anyway, I don't see any legit reasons for removing the ENT-E from active service and replacing it with the F so soon, and then F being replaced after only 20 odd years.
The writers either forgot about the fact these ships are designed to go on for 200 years, or they just prefer making new Enterprises for new series, and then make nearly identical ships in modern era that are based off a 100 year old design with minuscule adjustments to the exterior and call it another class of ships.
