I saw this rant/complaint over on Reddit, and it got me thinking a bit.
We know that at least on paper, Federation starships are insanely fast and agile. Data has stated that the Galaxy-class Enterprise was able to achieve Warp 9 from , and some ships, like the Nebula class, don't seem to use impulse engines at all, favouring the warp engine for sublight speed usage at all.
Despite that, we also know that impulse engines aren't simple thrusters, and are able to move the ship in a way not directly in line with the output thrust (Relics), and from the same episode, we also know that smaller ships, like the Jenolan, will still run rings around ships like the Enterprise, even though it is nearly a full century out of date.
However, from what the show itself portrays, the ships tend to be fairly slow and sluggish when in combat, sedately drifting along the battlefield, while weapons fire goes every which way. The most recent and active thing we've seen a big starship do is maybe the fighter run in Picard.
In my opinion, by trying to keep to the slow and seemingly logical expectations for starships to be slow, hulking metal structures that slowly fly around shooting each other, Star Trek ends up underselling what Federation starships are able to do. They would be more realistically portrayed flitting about the battlefield like dragonflies, instead of being like "real boats" today, that have more of a sense of mass.
It seems wildly unintuitive, but it would also help show Federation propulsion technology being more advanced than what they are now. Starships can instantly stop and reverse course, or move in ways that would be impossible with modern technology, and the show not showing ships capable of doing just that might be to its detriment.
One thing that irked me about Picard S3 was how agile the ~~Millennium Falcon~~ Enterprise D was flying into the core of the ~~Death Star~~ Borg Cube. I found the ships being big lumbering hulks much more entertaining as they had believable weight to them.
Of course we have things like The Picard Manoeuvre, but look how much time they spent explaining a second of combat. One of the bigger flaws of new trek is how agile everything is, just a lot of visual noise with random shapes and sizes zooming around like fighter jests with no consideration for inertia. If we just had huge ships flitting around the battlefield like Nightcrawler then you'd lose all sense of relatability and it would just be pure visual noise.
Wait, didn't they do that in Discovery to beat the Klingon ship or something? That was not enjoyable Trek to me.
I assume the restored Enterprise-D was lightly loaded and only had the bare minimum needed for it to operate and didn't have most of the working facilities of a fully-manned Galaxy class ship and there would have been a lot more power reserves available that allowed it to pull off crazy maneuvers.
Many areas of the ship likely didn't have life support and inertial dampeners would have only been used in parts of the ship that were habitable like the Bridge.
In other words, the restored Enterprise-D is a stripped-down hot-rod.
