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.
