  1. Why did the IJN, in the 1930s and 1940s, find the use of compressed oxygen as an oxidizer for high-speed underwater engines an easier engineering problem than the use of high-test peroxide for the same purpose (bringing the oxygen-powered Long Lance torpedo series into operational service in the 1930s and the derivative Type 1 kaiten later in the 1940s, while the HTP-powered Type 2 kaiten ran into insurmountable oxidizer-storage problems that prevented it from ever entering service), while for the Kriegsmarine it was the other way around (managing to bring a number of Walter U-boats close to entering service during the war years, while rejecting oxygen-powered engines outright because they realized they'd've had even more problems with that than they had with the HTP boats, only being able to finally start work on an oxygen design partway through the war as a result of a decade of additional technical advances)?
