Not really.
SOSUS is/was a passive acoustic sensor: SOSUS is a listening device and subject to the same limitation all passive arrays are, the physics of sound propagation in water.

Trust me I'm not trying to wear you guys out concerning ASW (which the passive phase of the search for the ping from the 777 really was), but I did it for many years as part of my job flying SH-60's.
I am, frankly, looking into the Penguin Bombers...
