The howitzer
The carronadas was a problem when aiming the weapon to its maximum reach, since its balance of weight and diameter of cannon towards the unstable weapon, and after each shot had to adjust again the height of the shot. The response of the Spanish Navy to this problem was the howitzer, a weapon that followed the same principle of shooting the carronada shallow but with a better balance in weight and better clamping system to be more stable, adding to this the ability to perform Curved shots.
He could shoot the same type of ammunition of shrapnel that the carronadas or realize a curved shot with experimental explosive grenades very dangerous in its handling. The ship Santa Ana was the first to incorporate them for the tests. The shells were just as manoeuvrable as the carronadas, but with greater accuracy at maximum distances.
