The Normandie Class Aircraft Carriers are an experimental design.  The lessons learned in their construction and operation will prove valuable in the construction of new French and Russian aircraft carriers.

Normandie Class Aircraft Carrier, laid down 1914
     Length, 175.6 m x Beam, 27.0 m x Depth, 9.2 m
          19790 tonnes normal displacement (18706 tonnes standard)
     Main battery:       8 x 15.5-cm
     Secondary battery:  6 x  7.5-cm
     AA battery:         8 x  3.7-cm
     Light battery:      4 x  1.3-cm
          Weight of broadside: 454 kg
     4 TT, 53.0 cm
     Main belt, 9.0 cm; bow and stern, 3.0 cm
     Upper belt, 5.0 cm
     Torpedo bulkhead, 5.0 cm
     Armor deck, average 5.0 cm
     Conning tower, 10.0 cm
     Battery armor:
          Main, 5.0 cm shields / secondary, 2.5 cm
          AA, 2.5 cm shields 
     Aircraft - 40
     Maximum speed for 37451 shaft kw = 25.00 knots
          Approximate cruising radius, 10000 nm / 10 knots
     Typical complement: 834-1085

                    Estimated cost, $5.159 million (1.290 million)
          Remarks:
     Oil firing.
     Relative extent of belt armor, 40 percent of 'typical' coverage.
     Main belt does not fully protect magazines and
     engineering spaces.
     Ship has slow, easy roll; a good, steady gun platform.
     Excellent seaboat; comfortable and able to fight her guns
     in the heaviest weather.
     Magazines and engineering spaces are roomy, with superior
     watertight subdivision.
     Ship is roomy, with superior accommodation and working space.
     Main deck secondary guns subject to being washed down
     in a seaway.

          Distribution of weights:

                                              -----
                                              19790 tonnes = 100 pct
          Estimated metacentric height, 1.9 m
     Displacement summary:
          Light ship:             18227 tonnes
          Standard displacement:  18706 tonnes
          Normal service:         19790 tonnes
          Full load:              20578 tonnes
          Loading submergence 2800 tonnes/metre

     Estimated overall survivability and seakeeping ability:
          Relative margin of stability: 1.25
          Shellfire needed to sink: 16050 kg = 310.8 x 15.5-cm shells
               (Approximates weight of penetrating
               shell hits needed to sink ship,
               not counting critical hits)
          Torpedoes needed to sink: 6.8
               (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, 0.03
          Relative quality as a seaboat: 1.63

     Hull form characteristics:
          Block coefficient: 0.45
          Sharpness coefficient: 0.36
          Hull speed coefficient 'M' = 6.51
          'Natural speed' for length = 24.0 knots
          Power going to wave formation
               at top speed: 49 percent

     Estimated hull characteristics and strength:
          Relative underwater volume absorbed by
               magazines and engineering spaces: 60 percent
          Relative accommodation and working space: 138 percent

          Displacement factor: 223 percent
               (Displacement relative to loading factors)

          Relative cross-sectional hull strength: 2.09
               (Structure weight per square
               metre of hull surface: 1246 kg)
          Relative longitudinal hull strength: 4.11
