Hi Tony

It,s only American subs that have sails. British subs have bridge fins, not conning towers as some people call them.

Fins,Sails, Conning towers, Bridges Modern submarines spend 95% of their time at sea submerged unlike the older submarines of my days but they still have to surface at sea some times ... the deck of a sub is like a half tide rock and you often cannot often open a main deck hatch because of the sea conditions so you need a tower hatch
. Other reasons are stability { the fin helps stability} and to move instruments like radars. periscopes ,Com's aerials to be carried above the hull i...t also allows a platform for that superb viewing instrument the "Mark 1 Eye ball.

When they figured out how to build longer periscopes that reached into the hull. Previously you need a separate dry area higher up where you could use the pericopes. Now ofcoures we have photonic masts that dont penerate the pressure hull.

At one time most battle ships etc had conning towers - it was the armoured tube inside the bridge.
