@EmpirePL: Torpedo loading works differently from shell loading -- the first salvo for
each launcher is "free," while reloads use a ship's shell space (armament space at
trainworld).
examples: A Fubuki. Note the 24 space (23 used from torpedoes and depth charges)
A Brooklyn. Note the 0 space available.
There's apparently a bug where ships with 0 armament space (no reloads) sometimes can't
load the first salvo, but as all serious setups with these ships are better off running
AA, hedgehogs, or supports in those slots...
