I hope this doesn't qualify as a necro (there isn't a warning over the reply box), I've been going over some past threads and wanted to address this.
The statistics (assuming the 80,000 tons number is correct) do not contradict each other at all, Germany undertook a series of projects to construct weapons production facilities throughout the war, many of which were still ongoing when it ended. The quote said "by 1944," not for the entire war. What probably happened was limited production through to late 1943, then production at or near capacity for a few months before the economy collapsed.
The point was that they did have the capacity for production on a very large scale, which would also have applied to the manufacturing of warheads for the V-1 and V-2. Although the Ar 234
https://en.wikipedia.org/wiki/Arado_Ar_234 is a possible delivery system for the 1944-45 timeframe being "nearly impossible to intercept" according the article.
The Axis needs oil. They have just defeated the USSR. But it's a big assumption that they would confiscate Soviet oil stocks???????? You do know the Germans seized French oil stocks after the Fall of France?
While the Luftwaffe sits there and does nothing apparently.
