Abstract
A submarine is provided with an upwardly directed drilling device (12, 12'). The drilling device (12, 12′) is arranged in a pressure hull (4) of the submarine and has a drill (14, 14′) which can be extended out of the pressure hull (4) through an opening (10) arranged on the upper deck of the submarine. The drill has a drilling head (42, 42′) which forms a closure body which closes the opening (10) of the pressure hull. The drill functions to drill a hole from under an ice sheet to allow occupants of the submarine to exit through the hole.
