 This was the last turbojet design in progress before the war ended and which had the highest thrust rating at 1,300 kg of thrust.However, the Ne-330 consumed 1.95 kg of fuel per kg of thrust and six Ne-330 engines would have resulted in the K-200 needing to devote a large portion of its weight for fuel.A consequence of this would be a rather short operational range, inferior to the main IJN flying boat, the Kawanishi H8K "Emily", even through the speed would have been faster.
