New one to me. 500 tons? What a monster that would have been. The H11K Soku was the KX-8 internally to the company. If the designators went in order, then one can surmise that the KX-3 was a proposal which pre-dated the H11K. Still, I bet no sane military official would have given such a proposal much thought. A transport that big would have been highly vulnerable, regardless of the armament it may have carried. Just look at the Me 323's vulnerability when flying without benefit of air cover.
I'd love to know more about the design but I suspect it was a flash in the pan and was quickly shelved to work on more promising, and more realistic, designs.
