Franz Joseph's technical manual isn't canon.
Agreed. Though, it is a "good fun" read that is more fun than anything else. Portions were used as screen and/or audio filler in ST1 through 6, making those portions, and only those portions, canonical.
That confused the hell out of me. I definitely need pictures of all these classes to be able to understand the differences.
Go
here. Its all the same ship because, well, its all the same ship. Even in the (non-canonical) tech manual they are just sub-class variants of the parent,
Constitution.
A series of command cruiser versions (Endeavour Class) followed and also the more combat orientated Achenar and Tikopai classes. In TOS and ENT the 1764 Defiance is an Achenar Class cruiser.
First its
Defiant not Defiance. Second, it is
Constitution Class.
The Enterprise A is listed as of the Enterprise Class, which defines the rebuilt Constitution / Achenar / Tikopai Classes. The Enterprise A was formally the USS Levant (Achenar Class)
Enterprise class refers to the bridge simulator only. No starship existed ever under this class designation. It is an admitted studio goof and this is the compromise. Please read
this and
this and finally
this. There really isn't anything to support what the Ent-A used-to-was, if anything, prior to ST4. Except this:
According to Gene Roddenberry, the NCC-1701-A was not a newly-constructed ship, but instead was the renamed USS Yorktown, a nod to the name of the starship in his original pitch for Star Trek. This was based on the fact that it was difficult to believe that Starfleet would build a whole new ship in such a short time, and then decommission it a short while after, and the early retirement of the Enterprise-A could be justified if the ship had been in service for many years under another name.
While not "on screen evidence", variations on this statement have floated around for decades, and I find anything coming from GR automatically more accurate and reliable than anything from Franz.
there were 12 x Constitution Class cruisers originally.
10 were actually new builds and two were rebuilds of previous similar classes (1017 Constellation (formally Horizon Class) and 1371 Republic (Republic Class))
There exists enough on screen evidence to support the 12
Constitution theory. While the
Republic and
Constellation may be old there is no evidence of either being of a prior class; however, this does not mean that a vessel of the same name could not have been of a different class.
In TOS the Republic is hinted at being a cadet training ship for final year academy students.
...and remained as such until at least 2374. See also DS9:"Valiant".
What ever happened to the Constitution classes I read everything there is on alphawikia and it really doesn't say except they were in service 20 more years after there major refit?
What really is the Enterprise A a new class or is it the renamed Yorkown alphawikia doesn't say much on this.It does seem different than all the other refits?
What is the difference between these ships and the Constellation class?What do you believe or your thoughts or interpretet?
The first two are more conjucture questions.I am just missing that old stlye of Trek these days.
Constitution production ended, but the ships still hung around.
Republic was a trainer vessel at Earth as late as 2374. An unknown Connie was lost at Wolf 359 to the Borg. Tough little ships.
*image removed due to EAS douche-baggery*
Enterprise's sets were refurbished into things such as alien vessels, the Ent-D, etc. and new parts needed to be built, notably the bridge (the engine room in ST6 is VERY obviously a redress of the Ent-D engine room). However, The Ent-A was just a refit
Constitution just like the
Enterprise it replaced.
Constellation class vessels only exist because Gene wanted something non-
Constitution to have been what Picard once had served on as Captain...
Constellations are newer but just old enough for a "young" Captain Picard to have had some serious fun in "back in the day".
Stargazer originally was
Constitution but Gene changed it in mid-stride to
Constellation (even re-dubbing the line Geordi spoke from one to the other).
Constellations are literally new heavy cruisers - they fill the role left by the aged and retiring Connies.
