Dry Deck Shelter

Dry a shelter deck (DDS) is a module that can be attached to submarines. It allows divers to easily enter and exit a submerged submarine.

Technology

In order to transport a DDS, the carrier submarine must be specially equipped, among other things, the fit of the hatches must be given so that the divers can get from the submarine into the module. In addition, connections for electricity and pipes must be present for the compressed air to the diver and Lenzen the lock. Also special devices for attaching the DDS must be placed behind the tower.

The DDS of the United States Navy are 11.6 meters long and 2.7 meters high and wide. They displace more than 30 cubic meters of water. They are transported by aircraft in a Lockheed C-5 Galaxy or by truck.

The shell of HY -80 steel, which is encapsulated in glass fiber reinforced plastic, consists of three divisions: One round decompression chamber, a transfer chamber and a hangar for a Swimmer Delivery Vehicle or 20 United States Navy SEALs Combat Rubber Raiding Craft with four.

In 2004, six DDS in service. The first of these was made ​​in 1982 by Electric Boat, the rest between 1987 and 1991 by Newport News Shipbuilding. Life expectancy is around 40 years. The DDS are designated DDS -01S to DDS - 06P. S stands for Star board ( starboard ), P for port ( port side). -01, -04 And -05 are hereby S. While the DDS at the U- boats of the Los Angeles-class and the Sturgeon class are equally attached to the midline, were four former missile submarines ( two of the classes Benjamin Franklin and Ethan Allen) Dry deck Shelters two wear, this the distinction between P and S was important. The four to Ship Submersible Guided Missile Nuclear converted submarines of the Ohio class can carry two DDS.
