Here is the Stealth Bomber and the Ho229 compared together. It is all right to admit that you are wrong.
The NAZI design, however, is not true stealth. It used charcoal coatings to “absorb” radar.
True stealth, involves complex geometries along with radar-absorbent coatings, the theories for the former being developed only in the 60s.
IIRC, a Russian engineer published a series of works on the math behind it, and the Soviets, thinking that the research was pointless, allowed for its international publication.
>The Germans in WW II developed stealth technology by the Horton Brothers. The developed the HO-229 in 1944.
Experimental HO-229 is nothing to do with “stealth” in modern conception.
Russia has advanced material science, airframe designs and math to implement stealth technology.
So why Russia should be “50 years behind of the USA when it comes to stealth technology?”
