Quick question. I am assuming that your information on the measurements of sound for the Russian ships and the US ships is from the Russian navy? Those numbers would make sense to me, if the Russian ships knew they were being monitored and were running silent. If these measurements were being taken by a Russian trawler off of Norfolk as a US sub left, I know that from what I have read the US subs will make all the noise they can while departing so that they are masking there "True" sound signature. So it is possible this may not be an accurate reading of the real capability of a 688. We would have to know in which context the readings were taken.
