Favorite Star Trek Ship Design

[The Valkyrie]

While I'm partial to Romulan ships in general, I really liked the Sovereign class Enterprise E and the Defiant (as see on DS9).  Also, the refit Constitution class Enterprise.

I really like the defiant . It's not a big capital ship . It's a sleek scrappy small scale skirmisher. It was also specifically built to kill Borg.

One of my favourite quotes from the movie First Contact, after Worf and the crew of the Defiant were beamed about the Enterprise.

Worf, "The Defiant?"
Data (I think); "Drifting but salvageable."
Riker; "Tough little ship."
Worf, "Little??"

I think I recall a description of the Defiant having more firepower than a Galaxy class ship.

There was something really good about watching that ship sweep in and blow a line of Dominion ships to hell.  It said, "The Federation will do what it can to prevent war, but if you insist, we'll kick your arse!"
