The Gvozdika Class Corvettes feature increased speed and range compared to the Pion Class

Gvozdika Class Corvette, laid down 1912
     Length, 65.0 m x Beam, 6.5 m x Depth, 2.6 m
          421 tonnes normal displacement (391 tonnes standard)
     Main battery:       2 x 10.0-cm
     Secondary battery:  4 x  3.7-cm
     Light battery:      4 x  1.3-cm
          Weight of broadside: 31 kg
     4 TT, 45.0 cm
     Hull unarmored
     Maximum speed for 9012 shaft kw = 29.00 knots
          Approximate cruising radius, 2500 nm / 10 knots
     Typical complement: 46-60

                    Estimated cost, $201,000 (£50,000)
          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.
     Cramped ship; poor crew accommodation, limited working space.

          Distribution of weights:

                                                       normal
                                                    displacement:
          Armament .........................      8 tonnes =   2 pct
          Machinery ........................    214 tonnes =  51 pct
          Hull and fittings; equipment .....    129 tonnes =  31 pct
          Fuel, ammunition, stores .........     44 tonnes =  10 pct
          Miscellaneous weights ............     25 tonnes =   6 pct

                                                421 tonnes = 100 pct
          Estimated metacentric height, 0.2 m
     Displacement summary:
          Light ship:               377 tonnes
          Standard displacement:    391 tonnes
          Normal service:           421 tonnes
          Full load:                443 tonnes
          Loading submergence 223 tonnes/metre

     Estimated overall survivability and seakeeping ability:
          Relative margin of stability: 1.08
          Shellfire needed to sink: 46 kg = 3.3 x 10.0-cm shells
               (Approximates weight of penetrating
               shell hits needed to sink ship,
               not counting critical hits)
          Torpedoes needed to sink: 0.1
               (Approximates number of 'typical'
               torpedo hits needed to sink ship)
          Relative steadiness as gun platform, 71 percent
               (50 percent is 'average')
          Relative rocking effect from firing to beam, 0.39
          Relative quality as a seaboat: 1.22

     Hull form characteristics:
          Block coefficient: 0.38
          Sharpness coefficient: 0.29
          Hull speed coefficient 'M' = 8.69
          'Natural speed' for length = 14.6 knots
          Power going to wave formation
               at top speed: 70 percent

     Estimated hull characteristics and strength:
          Relative underwater volume absorbed by
               magazines and engineering spaces: 186 percent
          Relative accommodation and working space: 66 percent

          Displacement factor: 40 percent
               (Displacement relative to loading factors)

          Relative cross-sectional hull strength: 0.46
               (Structure weight per square
               metre of hull surface: 115 kg)
          Relative longitudinal hull strength: 2.27
               (for 3.65 m average freeboard;
               freeboard adjustment +1.20 m)
          Relative composite hull strength: 0.54
