A polar bear chewed on the rudder of a U.S. submarine and then attacked it after the sub surfaced in the ice pack during maneuvers between the North Pole and Alaska this spring, the U.S. Navy reported last week.
The submarine "Connecticut," a new Seawolf-class sub, had partly surfaced with its sail and rudder sticking through the ice on April 27. An officer then looked around outside with the sub's periscope and noticed it was being stalked by a polar bear.
In a series of pictures captured on the periscope's camera, the bear apparently chewed on the rudder, then batted it around. The Navy says the damage was minor.
