I was looking through MAHQ today, and I found a few things that were interesting to me.

First, under ZAFT ships in GSD I noticed this was included, Gondwana. The only things in the description for now are it's length and that it is a heavy carrier ship. The length listed is 1200 meters. That is almost FOUR times the lenght of either the Archangel or the Minerva. It may be designed to transport the Destroy, though like I said it is listed under ZAFT.

Next while I was looking at the info for the Destroy, I noticed in one pic that the forearms are detachable, and at least according to the label under the pic there are cannons built in there.

And just because nobody was asking, and some of you probably don't care, under ZAKU Warrior it says that ZAKU means "ZAFT Armed Keeper of Unity".
