“The USS Kelcie Mae has a single warp nacelle, an underslung deflector dish, and a pointed hull rather than a saucer section. It’s this unusual physical arrangement that makes the ship stand out, at least from a visual standpoint. In fact, it reminds us distinctly of the Olympic-class USS Pasteur as seen in the alternate future of All Good Things under the command of Captain Beverly Picard …”
@MikeyMongol @snowyday Yeah, they even make a note of how unusual the Defiant is.
“Tough little ship!”
The Defiant is an interesting middle ground, basically a corvette type of thing, and it’s only practical because it has a cloak and it’s (for the ST universe) grotesquely overpowered and overgunned. Well it’s only practical because the writers wanted it to be, but that’s the in-universe explanation.
