Would a Federation warship like the Defiant out gun a Star Wars Star Destroyer? Who has a bigger armada? Who has the tactical advantage? Don’t forget that The Federation includes the Klingons, who love warfare and have fast, agile, heavily armed ships, with cloaking devices, and the Vulcans with superior logic and tactical planning.
One. Quantum torpedoes are many magnitudes more powerful than nuclear bombs. Even if that’s not enough to completely destroy a star destroyer, its certainly enough to destroy its power core (or whatever they call the power source in Star Wars).
