US Sub classes 1917-46
 

I was looking through Jane's Submarine Development and came up with a memorization trick for the US Subs used in Silent Hunter 4+ mods in the order they were developed. (It's an old school trick: make an easy to remember sentence out of names.)

For the pre-war subs I came up with "SAND Can Punish Sailing Ships"
Class (year) # Built

S-Boat (1917-24) 51
Argonaut (1928) 1
Narwahl, Nautilus (1930) 2
Dolphin (1932) 1
Cachelot, Cuttlefish (1934) 2
Porpoise, Pike (1936) 10
Salmon (1938) 6
Sargo (1939-40) 10

For the wartime subs "Time to Get Good Basic Torpedoes."

Tambor (40-41) 6
Garr (40-41) 6
Gato (42-44) 73
Balao (43-47) 127
Tench (44-46) 33

Now, if there was only a trick to learning all of those merchant classes.

Ooooooo! Pretty darned snazzy! Well done!:up:
