Hey i just had an idea. USing the "Retirement" system of ending patrol careers after a certain time there should also be a period in which your boat goes through an "Extended Overhaul". Say after 3-6 patrols, a message should come up similar to that of a crew tranfer etc saying "Your boat has been selected for refit and extended overhaul. 2 Months until completion". So here is a scenario..
Johaan Kepler
VIIC U=371
Career Start Date 5/10/1940
Patrols 4
Current Date 3/7/1941
At Patrol 5 A window comes up "U-371 needs refit and overhaul. Time till completion 5.23.1941"
I think that would add a degree of realism to SH3. And i dont know if sh3 commander can do this, but maybe they select refit/overhaul based on # of patrols plus # of ships sunk. Ships sunk usually lead to evasion tactics afterwards so it assumes that u took damage. Or maybe u modding guys can think of something better
