The surface navy is the surface ships that make up a strong portion of the navy.
The German Navy did use its surface ships, but the U-boats were able to attack without being seen.

There is no Navy rate or rank "SW"; SW is a warfare specialty designation that stands for Surface Warfare, or one who has completed qualifications for the SW badge. It's equivalent to a submariner's dolphins badge, or an aviator's wings.
The "traditional" tattoo for U.S. Navy deep sea divers is the age old U.S. Navy Mark V (MOD 1) deep sea diving helmet. The tattoo is normally worn on the lower leg. This helmet is also the the rating badge and warfare device now worn on the left sleeve and upon the chest of U.S. Navy surface supplied aka "Deep Sea" Divers. It is strongly looked down upon for U.S. Navy SCUBA divers to consider wearing this tattoo and most know not to. U.S. Navy SCUBA divers have not completed the same rigorous training as their "Deep Sea Diver" counter parts, and are not authorized to bear the surface supplied diver insignia.
The missiles are pushed out of their silos with compressed air and rise to the surface literally in a bubble of air. Very little seawater comes into contact with the missile until it breaks the surface of the water. The missile is ignited at the surface and the guidance system steers it to it's target.
