Awesome!!

Tokuro-2 (KR-10) Rocket Motor.
During the wartime, Japanese navy seems to have brought back perfect German technical data on this motor although the submarine I-29 which carried actual sample had been sunk on the way back home. The piping is exactly same as Walter 109 509A and I have been much impressed.
Thanks.

Shinpachi, it is my understanding that Navy Commander Iwaya had the Me163 instruction manual with him that was used to reverse engineer the aircraft and engine - this was because he flew home from Singapore when I-29 docked there to resupply.

Mitsubishi announced in the postwar that they developed the J8M based on the Me-163 manual with hardships because no sample was given but I begin to wonder if it was a little bit exaggeration. As a common sense, a maker can build a product without sample if the specification and drawings are given. No sample but Iwaya could answer engineers' question as he witnessed actual product in Germany. This picture, for example, introduces the 10th former of the J8M1 Shusui. Structure is almost same as the Me-163 and no one can draw this in imagination or oral advice only. I think that the reverse engineering could be a myth.

Good to compare with the Me-163.
Mitsubishi only had to build according to the drawings adding modification for their conveniences.
This is my temporary conclusion
