VIIC/42 depth
 

wasnt the /42 supposed to be able to go 500m deep? It had a hull about 2 inches thick as opposed to the 1 or so inches on pretty much every other submarine. In game it is only able to reach ~300m before crushing. Is that correct?

Maximum hull thickness 28mm with a diving depth of 200 metres and a crush depth of 400/500 metres:
