The Gambetta Class is an obsolete Armored cruiser, which will be replaced as new construction allows.  The class underwent refit in 1915-1916.

Gambetta Class Armored Cruiser, laid down 1901
     Length, 146.5 m x Beam, 21.4 m x Depth, 8.4 m
          13276 tonnes normal displacement (12464 tonnes standard)
     Main battery:       4 x 19.0-cm (2 x 2)
     Secondary battery: 16 x 16.5-cm
     QF battery:        24 x  4.5-cm
          Weight of broadside: 1408 kg
     3 TT, 46.0 cm
     Main belt, 15.0 cm; bow and stern, 12.0 cm
     Upper belt, 7.0 cm
     Armor deck, average 5.0 cm
     Conning tower, 20.0 cm
     Battery armor:
          Main, 20.0 cm / secondary, 16.0 cm
          QF, 6.0 cm 
     Maximum speed for 19197 indicated kw = 22.00 knots
          Approximate cruising radius, 5000 nm / 10 knots
     Typical complement: 618-804

                    Estimated cost, $5.189 million (1.297 million)
          Remarks:
     Relative extent of belt armor, 168 percent of 'typical' coverage.
     Ship has slow, easy roll; a good, steady gun platform.
     Good seaboat; rides out heavy weather easily.
     Magazines and engineering spaces are cramped, with poor
     watertight subdivision.
     Cramped ship; poor crew accommodation, limited working space.
     Main deck secondary guns subject to being washed down
     in a seaway.

     Estimated overall survivability and seakeeping ability:
          Relative margin of stability: 1.22
          Shellfire needed to sink: 3842 kg = 40.4 x 19.0-cm shells
               (Approximates weight of penetrating
               shell hits needed to sink ship,
               not counting critical hits)

     Hull form characteristics:
          Block coefficient: 0.50
          Sharpness coefficient: 0.38
          Hull speed coefficient 'M' = 6.21
          'Natural speed' for length = 21.9 knots
          Power going to wave formation
               at top speed: 48 percent

     Estimated hull characteristics and strength:
          Relative underwater volume absorbed by
               magazines and engineering spaces: 119 percent
          Relative accommodation and working space: 87 percent

          Displacement factor: 89 percent
               (Displacement relative to loading factors)

          Relative cross-sectional hull strength: 0.96
               (Structure weight per square
               metre of hull surface: 548 kg)
          Relative longitudinal hull strength: 1.41
               (for 4.25 m average freeboard;
               freeboard adjustment -0.64 m)
