Predreadnought Battleship Andrei Pervozvanni, laid down 1904
     Length, 140.0 m x Beam, 24.5 m x Depth, 8.2 m
          17014 tonnes normal displacement (15382 tonnes standard)
     Main battery:       4 x 30.5-cm (2 x 2)
     Secondary battery:  8 x 20.3-cm (4 x 2)
     QF battery:         6 x 20.3-cm
     Light battery:     12 x  4.7-cm
          Weight of broadside: 3216 kg
     2 TT, 46.0 cm (submerged)
     Main belt, 21.5 cm; bow and stern, 10.0 cm
     Upper belt, 13.0 cm
     Torpedo bulkhead, 5.0 cm
     Armor deck, average 10.0 cm
     Conning tower, 20.0 cm
     Battery armor:
          Main, 20.0 cm / secondary, 15.0 cm
          QF, 15.0 cm / light guns, 5.0 cm shields 
     Maximum speed for 11055 indicated kw = 18.00 knots
          Approximate cruising radius, 6000 nm / 12 knots
     Typical complement: 745-968

                    Estimated cost, $6.214 million (1.554 million)
          Remarks:
     Oil firing.
     Relative extent of belt armor, 90 percent of 'typical' coverage.
     Main belt does not fully protect magazines and
     engineering spaces.
     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.
     Main deck QF guns subject to being washed down in a seaway.

     Estimated overall survivability and seakeeping ability:
          Relative margin of stability: 1.20
          Shellfire needed to sink: 5638 kg = 14.3 x 30.5-cm shells
               (Approximates weight of penetrating
               shell hits needed to sink ship,
               not counting critical hits)

     Hull form characteristics:
          Block coefficient: 0.60
          Sharpness coefficient: 0.44
          Hull speed coefficient 'M' = 5.46
          'Natural speed' for length = 21.4 knots
          Power going to wave formation
               at top speed: 44 percent

     Estimated hull characteristics and strength:
          Relative underwater volume absorbed by
               magazines and engineering spaces: 111 percent
          Relative accommodation and working space: 99 percent

          Displacement factor: 99 percent
               (Displacement relative to loading factors)

          Relative cross-sectional hull strength: 1.00
               (Structure weight per square
               metre of hull surface: 746 kg)
          Relative longitudinal hull strength: 1.76
