The U.S. Navy has officially released information on the "Polar Bear Attacks American Submarine" incident. On April 26, in an area of polar ice between Alaska and the North Pole, the U.S. nuclear submarine Connecticut (SSN 22) surfaced. Subs in the arctic have long ago learned to look out for polar bears, especially if some of the crew are allowed out on the ice. In this case, a large (700-800) pound polar bear was seen approaching the sub. For about 40 minutes, the bear loitered around the subs rear rudder. It took a bite out of the rudder and, finding it inedible, stayed around the area of broken ice around the rudder for a while, apparently thinking a seal (the bears favorite food) might use it as an air hole. The bear finally left when he heard the noise of an approaching helicopter.
