Absent reverse engineering all those elements, Dreadnought and the screw galleys won't be able to face the other Thunderers coming to the Gulf of Dohlar.
While it's true that having the ship itself will no doubt help with *construction plans* for similar vessels, there are limits as to how much knowledge can be extracted just by looking at it.
For example. Steel formulas. Without spectroscopy, or a very profound knowledge of chemistry, it's unlikely a piece of steel is going to give up much of the details of it's manufacture. Probably not even all that much about it's component "mix" proportions, or even it's tempering process. Without knowing the actual process, attempting to duplicate it is basically a lot of trial and error - which, without Owl and Merlin, would have been what Charis would have had to do to develop it on their own.
Also, a large part of designing a vessel needs detailed knowledge of the properties of what it's built out of. Perhaps more so in the King Harralds than a mere ironclad, but the difference is more one of magnitude rather than type. If Dohlar can't duplicate the properties of the steel Charis produces, then it's likely any ships they build won't be as "hardened" as Charis's. While a more brittle steel might still be better than mere wood, it's not going to be as good as something with higher tensile strength.
Explosive mixtures are similar. The AOG had captured "corned powder" before; but until the spy at the powder mill actually obtained *how* it was made, the AOG manufacturers had no idea how to duplicate it. No doubt with enough experimentation they might have stumbled across the method, but also perhaps not.
