Although the US (allegedly) no longer operates them, they (and Russia and China) have used extremely low frequency communications stations spread out over miles to communicate with submerged submarines. Tensions are much lower now so submarines can take the risk of surfacing for communications checkins but I'm sure that the ELF stations could be recomissioned fairly quickly if the need arose
