The Polish submarines interned in Sweden remained more than inactive vessels. Sweden maintained both the boats and their crews, so a German action that drove Sweden into the war could release trained submariners and usable hulls. Those boats alone would not reverse the regional balance of power, but they added uncertainty to German calculations. Neutrality could therefore hold ready military capabilities that continued to complicate an adversary's planning.
