Price of ww2 tanks in todays money

vuque:   - First of all German production line at that time was designed to produce boxy tanks instead of the sloped ones.  - They knew that sloped armor provides better protection but at that time, they didn't feel the need to switch their production lines to produce sloped armor tanks due to the high cost of that conversion of the production line. They simply said, ah 100mm of frontal armor is enough for anything at that time. - On top of everything, sloped armor brings ergonomic problems such as the less space inside the tank and that was a real concern for the Germans at that time because they wanted to have more space inside the tank for the radio operator, extra ammo etc.
