Looks like a Victor III
They make lousy subs
I dunno...We were all over a Victor III about 400 miles off of San Francisco back in 1987, IIRC...
The captain of that boat was pretty good at utilizing thermal layers, and creeping slow and low along the bottom trying to evade us...It was a good match for about 18-20 hours while we played...
We’d lose him every now and then, but re-acquire after someone farted, or dropped something (transients) in that boat...
At the end of the time we had, the guy actually surfaced, gave us a nice “Good game” signal, and they motored off west for about 4 hours...The crew was even coming out on deck for a little sun as we parted ways...
The detection gear between us and the Kuril’s kept him generally going home till the intel let them drop off the boards...
I really think it is the skill of the crews “first”, and a little of the boat second...
A sub can probably get off a few shots, might even get lucky, but once those pants have dropped, there IS a whole lot of attention going to be put on you in very short order...And we do not let go until it goes away...
The biggest threat I know about is the diesel-electric boats out there...In sufficient number and in waters that degregate our equipment, that is the most threatening environment to play in...But that is common knowledge...
Just my experience and opinion...
