When in battle

 * Durring sea battles, Fire Ships deploy to the front battle line.
 * 7 Fire Ships fill the front battle line space of the Mini, Small and Medium battlefields. The Mini, Small, and Medium battlefields have 3, 5, and 7 front battle line spaces, respectively, allowing for 21, 35 and 49 on the field for those sizes of fields.
 * 10 Fire Ships fill the front battle line space of the Large battlefield, and there are 7 spaces, allowing for 70 on the field.
 * 12 Fire Ships fill the front battle line space of the Big battlefield, and there are 7 spaces, allowing for 84 on the field. __NOWYSIWYG__

Construction times
$$Construction \ time \ = \left \lceil Base \ time \times 0.95 ^ {n - n_0} \right \rceil$$
 * where :
 * Construction time : The calculated time (in seconds) needed to construct the specific ship on the nth Shipyard's level.
 * Base time : The time (in senonds) needed to construct the specific ship on the Shipyard's first level that the specific ship can be constructed [ for this ship 30 minutes = 1,800 seconds ].
 * n : The nth Shipyard's level.
 * n0 : The Shipyard's first level where the specific ship can be constructed [ for this ship is the  Level ].

1 - 10 = 11 - 20 = 21 - 30 = 31 - 38 =
