It's impressive but it's not that impressive doing it during peace time, I wonder how well they would do shifting this stuff around the globe when subs start hunting their ships
It also makes me wonder, is WW2 the last time we'll ever see wartime manufacturing on the scale it was ? for example Japan built 6 carriers in 3 years, while the US built 17, Germany built over 1,000 Uboats for the duration of the war, Russia managed to lose 83,000 tanks 76% of their inventory which was over 100k even plucky little UK managed to produce just under 28k tanks lol
I just can't imagine those kinds of numbers ever being seen again in such a short space of time, especially with nukes being the end game to halt any kind of manufacture like that from the main players who would be involved in a world war
