Explanation: One of the reasons why the USA could supply the UK during WW2 was because, even with the full force of Nazi ‘wolf packs’ of submarines hunting supply ships, the US could produce supply ships at such a ridiculous rate that the Nazis literally couldn’t sink them fast enough to dent the numbers - even if Allied naval forces weren’t whittling Nazi submarine numbers down at the same time.

Hilfe, I am drowning in ships, Kapitän.

The US built over 2000 Liberty ships and a few hundred Victory ships during WWII. While we were doing that, we also built some 800 warships including a couple dozen fleet carriers, several dozen escort carriers, eight fast battleships, dozens of cruisers, and hundreds of destroyers, destroyer escorts and submarines. And that’s just ships. The US was building shit in the 40’s.
