[net.politics] USN Carrier collides with Russian sub

	I can't believe that neither the sub nor the carrier knew
	nothing of the other's presence.  Comments, please, if you
	have real information or experience with such systems?

Disclaimers:  I was not on either vessel, nor I am omnipotent. 
Therefore I could be wrong.  As a former submarine officer, I know a
little bit about the games that submarines are capable of playing,
and I know a bit about the detection capabilities of subs (ours and
theirs).  The following is my own, *unofficial* opinion.

It is enormously more likely that the Kitty Hawk was ignorant of the
sub, than that the sub was ignorant of the carrier.  The carrier
(generally) makes much more noise than even a Russian sub, and hence
is easier to detect.  In addition, the acoustics of sound generally
favor a submerged platform detecting a surface-running vessel.

Naturally, the US Navy knows this, and generally takes steps to
catch any subs in the area of a carrier task force.  Such steps may
include bringing along an American sub to counter-detect the Russian
sub, towing sonar cables, or using airborne Anti-Sub detection
devices.  If we had a sub along, I bet we knew where the Russian
was; if not (and no one will be telling), the odds aren't great that
we knew he was there.

There are three reasons for a sub to be so near the surface that is
may collide with a ship: the sub is preparing to surface (to go home
or to recover from some onboard casualty), to raise a mast (to
snorkel, catch special radio traffic, etc.), or to spy.  In all
these cases, a sub necessarily proceeds slowly and cautiously, to
detect surface traffic and to avoid collisions.

The fact that a collision occurred tells me that either the sub was
deep AND couldn't hear a whole task force due to freak sonar
conditions AND suffered a tremendous casualty that forced it to
surface in a hurry! (say, a big fire in the Engine Room), or else it was
spying and made a goof while navigating.  The first situation is the
only one I can imagine that would excuse the sub; the second sounds
much more probable.  Since the sub was reported to be chugging home,
I doubt the casualty theory although I can't rule it out totally.

A side question:  who said the Russian didn't know we were there?

in a recent news article, i read that u.s. reconaissance pilots in
honduras who overfly el salvador sometimes take along rocks to
drop on guerrillas in el salvador.  a quotation from one of the
pilots went something like: "we're just letting them know that if
we can hit them with rocks, we can hit them with other things as well."

could the russians be trying to convey the message "we can torpedo
your carriers any time we want?" (sort of a surface version of 
"chicken" that u.s. and russian pilots engage in from time to time.)

of course, carriers are the mainstay of our naval defenses, so
having the (perceived) ability to sink a carrier is a real victory
from the point of psychological warfare.

    My understanding of the incident is that the carrier's escort vessels
    had in fact been tracking a sub, but they broke contact when the task
    force was ordered to change course.  Once the Soviet sub got inside the
    group of American ships,
    ambient noise would have pretty completely "deafened" U.S. sonar
    to the sounds of the sub (the idea of ASW is to get them BEFORE they
    penetrate the cordon of escorts).  The same sort of masking would
    have degraded the sub's capabilities.  In addition, the stories I've
    seen indicate that the collision involved the stern of the sub, where
    sonar resolution is NEVER good 'cause of the sub's own engine noise.

    In other words, it was a lousy accident not reflecting either good or
    bad on the technology or techniques of either victim.  Just glad
    nobody (apparently) was hurt.

    Cheers.
