My understanding of deep ocean lifeforms is that they use BL as a lure and decoy mechanism: "Bite Here!" whether being sacrificial or enticing as
the only real utility of active lightsourcing in that deep a black.
Now if you are referring to normal (shark etc.) fish with dark uppers and bright lowers, I agree but they tend to operate within a much shallower
environment where surface diffusion is still powerful enough to provide considerable light.
And nuclear boats especially /hate/ operating in shallow water because there is no real easy thermoclinic definition of sound path and salinity to
gauge detection ranges and their plant/cav noises tend to become a real problem as they cannot use high performance sprint and drift techniques to
exploit the third-D in isolating their signature.
Inshore is therefore where I would expect optical camouflage to be most necessary.
That said, the Pacific units especially had a tendency up until the late 70's or early 80's to put a bluesh sail and turtleback on their boomers to
help hide them against a far horizon as they sortied out and I suppose this goes back to the days when a surfaced ICBM/CM launch scenario was at least
These days, my personal belief is that systems like April Showers have allowed us to penetrate at least the shallow littoral areas with overhead to
the extent that we can pretty well sanitize them by wake tracking and thermal plume differentiation if not actual silouhettes on most boats. There
may also be roboacoustics (fast lay SOSUS or mobile) involved too.
Could be wrong of course, but the inshore SSK threat is as real as ever and it doesn't make sense to continually chop out the area-search platforms
(S-3 and P-3) when missile poles and super cav are taking the engagement out past the second and third convergence zones.
