The first confirmed German U-boat in Canadian waters has been discovered off the coast of Nova Scotia. U-215 was on its way to mine Boston Harbour in July of 1942.

It was torpedoed and went missing. Sixty-two years later, it's been found.

Mike Fletcher, diver at Eco-Nova Productions in Halifax, says the last try to find the boat was successful. "When all hope was down, we made one last attempt and we nailed it right on.We've got 215 no doubt about it."

Fletcher is making a TV documentary about a lost Nazi submarine. His team of divers and marine archaeologists fought strong underwater currents to locate the submarine 90 meters below the surface, about 200 kilometres south of Shelburne, Nova Scotia.

Fletcher says the U-boat fell short of achieving it's objective of mining Boston Harbour.

"U -215 was a very specific boat, designed to carry mines and to terrorize and victimize Allied ports."

The submarine was torpedoed by a British ship en route. It is now the watery war grave of 49 German sailors.

John Davis, president of Eco-Nova productions in Halifax, says this U-boat was among select few with the capability to secretly enter harbours to lay mines while also carrying offensive weapons like torpedos.

"It is the very last of the D-class submarines. We're kind of closing a chapter on one of the most remarkable weapons of war that Nazi Germany produced."

Davis says it's unclear what will happen to the wreck, but he says the uninviting conditions make it unlikely the U-boat will ever be moved from the bottom of the ocean.
