I always forget just how large the defiant is. I feel like there is rarely anything close enough in the camera shots to get a good idea of scale. Other than DS9 I mean.
Although when they created DS9 in Star Trek Online, they had to massively scale it up because otherwise it would have gotten lost among all the players’ ships, both by sheer volume and because so many ships in the game are absurdly large.
Same thing happened to Bookers ship from Discovery Season 3 and 4. It can fit in the cargo bay (barely) of the Discovery and yet in the game it’s like a third the size of said Discovery.
