Submarine retirement

[armin]

Cam someone tell me what is the retirement date for certain subs?
I selected S-18 and im little bit worried i will be stuck there for a long time. Then again i dont want to select some sub in pearl and be stuck with it 80% of the game. Thanks.

there is no "retirement" age, however you will be offered new ships after a few good patrols. a much better sub.
