What are your thoughts on the ENT Bird of Prey, which is 95% indentical to the one in the classic movies, Next Gen and DS9?
Since this was directed at me, I'd be happy to answer.
First, as has already been mentioned, the ENT BoP is not '95%' identical to the movie BoP. But I think I know why you were making that point. So let me continue.
The ENT BoP came about because John Eaves recycled design elements from DS9's "Way of the Warrior" in 1995. One of his first jobs was to create new Klingon ship designs for Martok's fleet. However, rather than create more original and unique designs, he instead just used the K'T'ingas and BoPs as a base and just added things to them, gave them extra wings, etc. (I'm not dissing his work here; I'm merely pointing out the facts.) But the decision was made to just use the old designs for the fleet, since they could utilize model kits, Playmates toys, etc. for filming and for the destruction of the ships.
Now fast-forward to 2003. 2150-era Klingon vessels were needed, and instead of reusing the D5 that was introduced in "Marauders," Eaves designed a BoP based closely on the design he created back in '95 for WoTW. So essentially a ship meant for the in-show year 2372 was used for a ship from the year 2153.
Did Berman & Braga specifically tell Eaves to recycle his designs? Beats me, but his modus operandi tends to work that way. Is it a crime to reuse rejected designs later, even if it's not for the same time period it was originally designed for? At this point, I suppose that doesn't matter either.
However, I think that it was a fundamentally flawed decision to use a ship that was designed and mentioned by name as a "Bird of Prey" for a Klingon ship in the year 2153. Since STIII onward, there seemed to be a technology exchange between the Klingons and the Romulans, especially in the ship design department. But now thanks to ENT, it looks like two completely different alien races have ships that coincidentally resemble each other and are called the same thing, for no real good reason, a century before.
I know you did, and until now, I'd made more-or-less the same assumption I think you're making: that a TNG Miranda was essentially the same as a StarTrek IV Miranda. This conversation makes me wonder if that has to be the case, or do they make a "tribute" Miranda every 30 or so years? That might explain the subtle differences, and the occasional suggestion of different class names (Soyuz v Miranda, etc.)
I don't think so. I think Mirandas (for some odd reason) were a long-lasting design, but eventually they stopped producing them. Sure they were probably refit many times (which would explain the glowing nacelles and red bussards that the TMP-era Miranda's didn't have), but making new ones just to make them? I doubt that.
