The Mizuno "Shinryu" was built at the end of the war as the suicide
Kamikaze glider powered with four assist rocket engines for take-off. The
aircraft never flew and soon was abandoned in favor of more advanced
project, "Shinryu 2".
This type was intended for interceptor and ground attack role. Four
powerful Toku-Ro 1 Type 2 rocket engines, 600KG each were to propel
this wooden aircraft up to the operational speed and altitude within 30
seconds as this was the endurance of these rockets.
Canard layout was chosen for best top speed. Small spoilers were
added to the wings for better handling characteristics. Armament consisted
of six-eight rockets. Take-off was to be performed from the trolley similar
to that used for Mitsubishi J8M Shusui. Three retractable skids were to be
used for landing.
As a B-29 potential interceptor, Shinryu 2 was to fly at extreme altitudes
where the air pressure is so low, that a pilot can't survive without
special equipment. To solve this problem a special pressurized suite was
to be used instead of heavy pressurized cabin.
Shinryu 2 was never built mostly because of the end of hostilities.
