I run a set of tests, sea trial, after leaving port. A blurry scope I can live with, 3min to reload the Flack:hmm: , dive at first sign of planes.
I almost lost my U-54 on her second patrol upon testing max diving depth, the dive planes seemingly were jammed. The boat, type VIIb, started to take damage at 230m and when we finally got her to turn around we where below 250m.
You just never know before it happens
