Hello, I'm guest editor, I hope this will reach you as I don't know how this message system works. My edit was to specify which Sierra II submarine was in the Atlantic in 2012. As "Pskov" was being repaired, the only other possibility was "Nizhny Novgorod". It's just a logical deduction and requires no extra sources. I hope the situation is clearer now and the edit can be submited. Thank you.
