In the War Academy I read that the Ironclad is the first sea unit which is really valuable bor war.
I think that this isn't completly true. In fact the first such unit for me is the frigate. The frigate can be realy useful for shore bombardements.
In fact a frigate can easily defeat fortified veteran wariors, archers, phalanxes, legions, pikemen. 50% of the time it defeats a fortified veteran musket and more often a non veteran one. And of course the frigate with its relatively high movement rate and attack strenght can also chase and destroy all the other ships of its time.
This is why I consider frigates a very valuable weapon on land and at sea.
And whyle I make a very extensive use of frigates in conquest, its not the case with ironclads which I rarely build since they have no transport capacity and I know that the destroyer comes just a bit later.
