 The IJN may have asked Kawanishi to consider a turbojet powered flying boat or it may have been a company initiative.Support for the latter comes from the IJN's request for the Kawanishi H11K Soku and the K-60, both large flying boats, and thus the suggestion may have been put forth.For such a large flying boat, the K-200 likely would have been powered by the Ne-330 turbojet.
