There's so much technology in Star Trek that could be weaponized, it's mindboggling.
I mean, a warp-based railgun alone would annihilate nearly any opponent with a single shot.
And USS Vengeance had TWO of them!
References? I just did a quick Google search and I can't find any mention of such. Are you confusing the torpedo launchers with railguns, let alone warp railguns?
(Hint, a single shot from a warp-powered railgun would almost certainly annihilate anything it hit. I mean, even a golf ball going as slow as, say, ten percent the speed of light would be devastating. Forget a heavy slug traveling in excess of C.
'Course, that would also make suicide warp ships the ultimate doomsday weapon in any war, especially for planets and moons, but that's never been an issue in Trek either to my knowledge. The Dominion War would have been over real fast if it were, with them winning hands down.)
