I know it would not work, its a very circumstantial scenario. But what i intended was that these ships could have served some purpose. rather than the biggest kamikaze ever. They would have accomplished something. And the IJN was not worryed about refueling, this shows with theyre suicide mission of the Yamato itself, it would have been a one way trip, out doing the best it could, with what it had. thats all i intended to say, they would have had the potential to do something, anything, instead of being wasted.
