That URL links you to a folder, which contains a test clip as well as the footage that needs to be doctored to fit the new line. If anyone with the ability to do so could make it work, I think we will have gotten away with this change pretty effectively.

As for the line, what about: “The fleet has heavily modified weapon systems”.
Yeah, though instead of “weapon systems”, maybe just “super cannons” or “superlaser cannons” or “superlaser helix cannons”, just to make it clear he’s talking about the big gun at the bottom. Or maybe we could just call them “Dreadnought-level laser cannons” so it’s immediately clear it’s a big deal.
