Unit-ship:Rocket Ship

__NOWYSIWYG__

Description
Thanks to our research, our scientists have managed to store large amounts of explosive power in wooden devices that can be blasted several hundred meters over the water`s surface and can cause a huge explosion if thrust on opposing ships. The enemy should be afraid - very afraid - of this lethal weapon!


 * During sea battles, the Rocket Ships deploy to the First Strike position.
 * 3 Rocket Ships fill a battlefield space. __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 1 hour = 3,600 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 ].
