Submarine retirement
 

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.

From each sub's "Interval" line in the upc file.
S-18 Class 12-30-1943
S-42 Class 9-3-1944
Narwhal 12-11-1946
Porpoise Class 11-11-1944
Salmon Class 2-23-1945
Sargo Class 12-11-1946
Gar Class 15-11-1945
Tambor Class 12-11-1946
Gato Class 1-16-1967
Balao Class 7-11-1963
Tench Class 1-1-1979

Two or three patrols on your sugar boat and they will offer you a new sub.:yeah:
