P-3 to the rescue
I was on the USS Seattle (AOE-3) in April 1984 while the cold War was still going on. We were a lightly armed servant ship. We were crossing the Atlantic out of Norfolk on our way to a med cruise. A Russian submarine was stalking us from below and we were no match for him. Thankfully a p-3 from the Azores came to our rescue! He latched onto Ivan with his stinger and circled the area, staying with us until all was clear. I then became a big P-3 fan!
