Polar Bear Attacks U.S. Submarine
Polar Bear Chews on Submarine
By ANDREW CHANGMay 30, 2003
A U.S. nuclear submarine has taken on some unusual damage during maneuvers.
As the new Seawolf class sub USS Connecticut surfaced in the ice pack between the North Pole and Alaska on April 27, a polar bear chomped on its rudder, then attacked it.
The Connecticut was only partly surfaced, with its sail and rudder sticking through the ice.
"When an officer looked outside through the periscope, he was surprised to find a curious polar bear stalking around the vessel," Petty Officer Jennifer Gray reported on a Navy broadcast.
Amusing the Crew
Mark Barnoff, a scientist with Pennsylvania State University's Applied Research Laboratory, had been working on a sonar experiment in the area, and was touring the Connecticut when the polar bear struck.
He said the polar bear's action caught the attention of the submarine's crew. "To watch the experienced sailors watch this, especially the older ones, was interesting," he said.
Barnoff took a series of pictures captured with the periscope showing the bear chewing on the rudder and then batting it around.
The bear stalked the submarine for around a half-hour, said Barnoff. "It wasn't in a rush to do anything. It was on its own schedule," he said.
Barnoff said by the time officers on the boat gave the all-clear, he was glad to leave. "It was a beautiful day," he said.
The Navy reported the damage to the Connecticut was minor. "Rear rudders of U.S. submarines aren't designed as snacks, but [the bear] had to find this out for himself," Gray said.
Seawolf-class submarines are among the largest attack submarines ever produced in the United States. They measure roughly 350 feet long by 40 feet by 35 feet.
Each Seawolf-class submarine carries a crew of approximately 130.

Geo and I were talking about this the other day. Don't know quite how the conversation ended up here, but it did. My class adopted the crews of the USS Dallas (SSN 700) and the USS Connecticut (SSN 22). Commander Clark had sent us a postcard telling us about their North Pole adventure and an uninvited guest who had mistaken their boat for a meal. What a cool way to learn about geography! The USS Connecticut is an incredible boat. I am lucky enough to have toured her... the technology on that boat is amazing, and so are the men who sail her.
P.S. Here is a little more information. Polar bear numbers are shrinking, and we all should be worried about that!
Bear Attacks SubDuring the ICEX 2003 naval exercises near the North Pole: the American submarine Connecticut (SSN 22) poked its sail and rudder through the ice. Thesub surfaced in an area of polar ice between Alaska and the North Pole 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. When an officer first looked around outside via the periscope, he noted that his sub was being stalked by a hostile polar bear. The periscope cam was turned on, and these photos of a polar bear chewing on the subs rear rudder resulted. The damage was said to be minor. The SSN 22 is a Seawolf class boat, one of the navy's newest submarines. It wasn't designed as a polar bear snack, but that's how life is sometimes.
There are over 20,000 polar bears living in Arctic waters (although some live in Hudson's bay and down the Pacific coast of Alaska.) The bears normally live on pack ice or ice flows and prey on seals. Some come ashore during July and August, when offshore ice melts. There they live off their fat, or dead sea life that washes ashore. Some have been seen as far north as the North Pole, but there's little food for them up there.
American submarines have been operating under the Arctic ice for over half a century. In August, 1958, the American nuclear submarine USS Nautilus (which is from CT and can be visited in a museum), passed under the ice at the North Pole for the first time. In the Summer of 1962, two U.S. nuclear subs surfaced at the north pole. All of this arctic activity was to prove that nuclear subs could operate up there, and that ballistic missile subs could launch their missiles there as well. American, and Russian, subs have been operating up there ever since. They have also used their sonar to measure the ice thickness and report that the ice has lost 40 percent of its thickness in the last 20 years. This has caused problems for the polar bears, who feed on seals that surface near offshore ice flows or through breathing holes in pack ice. Some bears are forced to come ashore earlier because of the longer warm season. This is caused by a combination of global warming and the normal fluctuation of Arctic ice thickness.
Submariners have seen polar bears in the past, but this is one of the few times that the bear saw the sub first, and apparently mistook it for the world's largest chunk of bear food.
