     Torpedo bulkhead, 1.9 cm 
     Armor deck, average 8.9 cm 
     Conning tower, 30.5 cm 

     Battery armor: 
          Main, 27.9 cm

          Remarks: 

     Caution: Hull structure is subject to strain 
     in open-sea conditions. 

     Relative extent of belt armor,
     123 percent of 'typical' coverage. 

     Magazines and engineering spaces are cramped, with poor 
     watertight subdivision. 

     Roomy upper decks; superior accommodation and working space.
