Abstract
A method for allowing underwater escape from a submarine includes attaching a lower escape tower connector of an escape tower to a hatch connector of a submerged submarine to sealingly attach a lower end of the escape tower to the submarine. A first riser tube is attached to an upper escape tower connector of the escape tower and second riser tube is attached to the first riser tube to form an escape tunnel. Water is replaced in an interior of the escape tower and a tunnel interior of the escape tunnel by air. An exterior hatch of the submarine is opened and a person passes through the hatch. The person is raised to the water surface through the tunnel.
