Danger Lurks in Sunken Sub

The Naval Service has been ordered to remove mines from a German U-boat on the Cork coast amid fears that unauthorized divers may trigger an explosion on the submarine, which is lying close to an underwater gas line.

The Naval Service has inspected the wreck of the UC42 on a number of occasions and recently discovered that seals it had put on the submarine had been tampered with. Unauthorized divers are suspected of having gained access to the site. (Irish Examiner)

UC-42+submarineThe UC42 was a World War 1-era German mine-laying submarine, most likely lost to one of it’s own mines while placing mines outside of Cork harbor. She wasn’t attacked, the British Navy was only alerted to her presence upon spotting a spreading oil slick in the harbor.

Unwilling to take any chances, they instead dropped a marker buoy … and then a depth charge. Bubbles and more oil floated to the surface.
