It's been a while, but In the episode where Destroys plans are shown, Its shown on two computers in the episode... one of which was the chairmans. Now, if you recall, the Destroys have the shielding on their detachable hands, so its rather reasonable that the chairman got it from there. Now how he had the plans, I do not know, but it is certain he got them and that episode was the first episode I saw him as the bad guy.
Personally I believe he had them because he helped create the design in the first place.
