Next question, before I have to go and do some chores:
If they are snooping around Japan and Okinawa, where have they been we dont know about? If they are entering into the the "game", whats the intent?
It wont be long before a 688 cleans their clock...of that I am certain. I have faith in CSS-7
They believe in a "soviet armor" approach to submarine warfare. Lots of mediocre boats to throw at our carriers when the time comes for them to take TW. They may be testing their "mediocrity", so as to find their own weakness before engagement.
Off the top, but it works...
"whats the intent?"
To calculate timing so they know a window of opportunity?
