USN Subs
Some S-Class boats + 4608 to 4644 in editor

Several subs have multiple patches, in some cases this is because I found multiple, this is true for
SHP_4613 	USS Cuttlefish
SHP_4641	USS Sealion
SHP_4874	USS S-27

Others have multiple alternatives because their patch made (I believe) reference to circumstances
and actions during the war. The first patch, that will be loaded is the original, the reference was removed
by me for the alternative patch.

SHP_4628	USS Seal, A tally of ships sunk is shown on the patch.
SHP_4887	USS S-41, Alaska shown on the patch, may be because she spent a large time of the war in Alaska
SHP_4890	USS S-44, The sinking of Kako is referenced on the patch
