ROTFLMAO. You think satellite photos are the only way we know a sub

...Well, we do have that radio-equipped kraken program, but I'm not
sure if that's been declassified yet. I mean, Greenpeace would be
screaming bloody murder about it by now.

I still say we just bribe Prince Namor to track the things...then Russia
hires Attuma, and China gets Aquaman.... seriously, the Russians were
the ones who spilled the beans big time on one technique that we wanted
kept secret. Submarines, even when at rest, make a slight change in the
profile of the water over their position- this was noticed when
satellite radar images of the sea's surface revealed the image of the
underlying terrain was being replicated on the water's surface shape, if
only in a difference of a matter of millimeters; of course a sub
underway is going to leave both a thermal wake and a slight change on
the surface height in it's wake as it moves and displaces water.
