Spring Style is designed for ships armed primarily with guns, but carriers become important from the end of World War I on.

The Method Edit

  1. Sim your hull.
  2. Use the waterline dimensions to determine the theoretical maximum number of aircraft embarked:  L (meters) * B (meters) / 70.
  3. Determine your air-group, subject to the limit of #2. If the total number of aircraft is less than 25, assign as miscellaneous weight 25 t per aircraft. If the total number of aircraft is 25 or higher, assign as miscellaneous weight the square of the number of aircraft (900 t for 30 A/C, 1600 t for 40). This figure includes all aspects of the aviation component - aircraft, fuel, ordnance, catapults, aircrew facilities. If the carrier is a conversion, multiply the required miscellaneous weight by 1.5 to represent inefficiencies of hull form, etc.
  4. If you chose an air-group greater than 70% of your theoretical maximum, you will require two hangars. This will determine your freeboard later on.
  5. For an open bow (Yorktown) or taking-off ramp (early Furious), raise or lower the stem as necessary. For an enclosed or hurricane bow (Ark Royal, sim a raised forecastle extending 15% of the ship's length. The carrier may have a modest lowered quarterdeck aft Courageous).
  6. For carriers in which the hanger floor is the strength deck and the hanger is a lightweight structure atop it (most Japanese and American carriers), your freeboard represents the hangar floor. If the ship has two hangars, the freeboard corresponds to the floor of the upper hangar. Bear in mind that there is probably an average cruiser-like freeboard between the waterline and the lower hangar floor. There is no need to simulate the hangar sides or flight deck - the weight is assumed to be relatively insignificant. Make a note directly under the SS report's "Armour deck" line that the ship has one (or 2) lightweight hangar(s).
  7. For armored box carriers, the freeboard represents the height of the armored flight deck.  Bear in mind that this will be atop one or two hangars and a typical cruiser-like freeboard. The thickness of the armor deck should be 150% of your intended average flight deck thickness (i.e., 4.5" if you want 3"). The extra 50% represents the weight of the armored hangar floor with the same thickness. Use upper belt armor to represent armored hangar sides. Length will correspond to hangar length, and height to your hangar height (4-6 meters, depending on preference). Make a note directly under the SS report's "Armour deck" line that the ship is an armored box carrier, and note the actual average thickness of the flight deck and hangar floor. Note also the number of hangars.
