Oh, I didn't say the VDS (which stands for Variable Depth Sonar, a big
fancy underwater microphone that could be lowered into the ocean on a
special cable) wasn't effective. I just don't think it's more than a
very tiny itsy-bitsy part of why the Soviet Union collapsed.


Great story though... still being talked about when I was in... thanks
for the link!

I left the ship 2 weeks before it happened. There was another incident about
a month before that involving 2 Osa missile boats but no one got hurt.



An incident on the ship I was on.... which was prbably not talked
about much outside that one ship.... the sonar gang had lowered the
Toad Array to about 600' while tracking a sub. Unbeknownst to the
conning officer, who drove the ship into water of about 450' depth...
and the taxpayers said "OUCH!"

I dunno if I'd take that statement too seriously. As a strategic
countermeasure to the Soviet Navy's overwhelming number of subs at the
time, they were designed to deliver nuclear depth charges with a
possibility of surviving. The InSurv board had quite a lot to say on
the matter.

During sea trials they were shock tested with 4,000 lbs (4 kT) of explosive:

The ASROC had a 10,000 lb (10 kT) yield:

'scuse me,,, 10,000 lb is 5 T, 10 kT is 20,000,000 lbs, small difference.

That certainly was a good blunder, eh? Missed it by that much...

That wouldn't have been much fun.
