The extreme cold temperatures of -55°F and colder are never recorded at sea level. You only get those kinds of temperatures at elevation. The ice in that video is no colder than 32°F, as the freezing temperature of water is the same as the melting temperature of ice. So a submarine breaking through the ice would never experience temperatures 32° below the freezing temperatures of water, let alone 132° below freezing temperatures.
