A successful submarine delivery could bring technical data and small quantities of special materials to Japan. Those supplies could advance experimental projects without giving Japan the resources to turn them into a decisive wartime capability. Jet aircraft and intercontinental bombing projects are examples of programs that might reach prototyping while consuming scarce material. The submarine's identity remains qualified: U-864 is presumed to be the intended boat after U-805 is mentioned and challenged.

Why U-864's cargo would not transform Japan's war
Technical data and small quantities of special material could support Japanese prototypes, but they could not replace the industrial capacity and resources needed for strategic effect.
