Well, warship class Dominion torpedoes are 2.75m in diameter and 27.5m long.
Basically they're the size of a fighter except the pilot, s seat is replaed by a huge warhead.
Even by conservative minimalist estimations the warhead is circa 15-15 tons 9f matter and antimatter with its blast roughly shaped to a frontal arc.
Then again you won't need to worry about this too much. It would only rarelycome up.
I really - really don't wish to devolve this to calcs and powerlevel discussion.
Our weapons are quite powerful but aside from really massive orb8tal bombardment nobody should be able to depopulate planets, much less blow them up.
Yes, I aim this to you, [@Keyguyperson].
Having something THAT powerful would mess up too many fun strategies.

Anyways, the Dominion isn't stupid and neither inept at diplomacy. They do acknowledge alliances, it's just in secret everybody is just vassals and inferior. Well, their arrogance isn't such a big secret but you get the point. We can say that the Dominion made an alliance with mutual gain to you. You receive support, can trade, exchange certain techs and resources plus if either one of you is at war the other is compelled to assist with their own military. You retain your autonomy and everything. This isn't any diferent what the more worthy Dominion vassals get but if the Queen doesn't like that title then they can just keep calling it as an alliance. :lol
