SOSUS areas were operated by numerous dispersed monitoring naval facilities, which over time consolidated into the NOPF and now TUSC of today. ..........".
Like all such developments, it's probably fair to say that the technology will have moved on considerably and the infrastructure significantly upgraded with other technologies being integrated into the IUSS and so on - just as SOSUS itself evolved in it's day. And we'd never know how that all looks now, and which elements of the old (say 1990's era SOSUS network) remain (probably much enhanced) - for obvious security reasons.

ORAC, I believe SOSUS equipment only became "dual use" after the Cold War ended whereby certain scientists with appropriate security clearances were given access to some of the SOSUS capabilities for their scientific work. It was never a case of "OK, we're off buddy, here's the keys to SOSUS ...... oh, and don't forget to feed the cat!".
