In the North Atlantic, ca. 1967.  A Russian Sverdlov forces Bowditch to abandon a Survey Line.  Cold War hijinks, with a rough edge.  Taken with a long lens in dim light. Compare the director tower atop the forward superstructure to the Janes' photo of Oktyabrskaya Revolutsiya in the next slide.  Note the masts of two other ships in formation astern.
