The Izyslav Class is a powerful, long-range Destroyer.

Russian Izyslav class destroyers, laid down 1914
     Length, 107.0 m x Beam, 9.4 m x Depth, 3.0 m
          1947 tonnes normal displacement (1736 tonnes standard)
     Main battery:       5 x 10.0-cm
     Secondary battery:  1 x  7.6-cm
     AA battery:         2 x  4.5-cm
     Light battery:      6 x  1.3-cm
          Weight of broadside: 78 kg
     9 TT, 45.0 cm
     100 tons depth charges
     Hull unarmored
     Battery armor:
          Main, 2.5 cm shields / secondary, 2.5 cm shields
          AA, 1.0 cm shields 
     Maximum speed for 30090 shaft kw = 31.75 knots
          Approximate cruising radius, 3000 nm / 15 knots
     Typical complement: 147-191

                    Estimated cost, $1.181 million (£295,000)
          Remarks:
     Caution: Hull structure is subject to strain in open-sea
     conditions.
     Oil firing.
     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.

     Estimated overall survivability and seakeeping ability:
          Relative margin of stability: 1.33
          Shellfire needed to sink: 207 kg = 14.9 x 10.0-cm shells
               (Approximates weight of penetrating
               shell hits needed to sink ship,
               not counting critical hits)
          Torpedoes needed to sink: 0.2
               (Approximates number of 'typical'
               torpedo hits needed to sink ship)
          Relative steadiness as gun platform, 70 percent
               (50 percent is 'average')
          Relative rocking effect from firing to beam, 0.22
          Relative quality as a seaboat: 1.20

               at top speed: 69 percent

     Estimated hull characteristics and strength:
          Relative underwater volume absorbed by
               magazines and engineering spaces: 197 percent
          Relative accommodation and working space: 102 percent

          Displacement factor: 58 percent
               (Displacement relative to loading factors)

          Relative cross-sectional hull strength: 0.50
               (Structure weight per square
               metre of hull surface: 151 kg)
          Relative longitudinal hull strength: 1.05
               (for 5.06 m average freeboard;
               freeboard adjustment +1.73 m)
