Industrial Revolution
For more details on this topic, see Naval tactics in the Age of Steam.The Industrial Revolution introduced steam-powered ironclad warships seemingly impervious to cast cannon. The inadequacy of naval artillery caused the naval ram to reappear as a means of sinking armored warships. The rapidity of innovation through the last half of the 19th century caused some ships to be obsolete before they were launched. Maximum projectile velocity obtainable with gunpowder in cast cannon was approximately 480 m/sec (1600 ft/sec). Increased projectile weight through increased caliber was the only method of improving armor penetration with this velocity limitation. Some ironclads carried extremely heavy, slow-firing guns of calibres up to 16.25 inches (41.3 cm). These guns were the only weapons capable of piercing the ever-thicker iron armour on the later ironclads, but required steam powered machinery to assist loading cannonballs too heavy for men to lift. USS Monitor demonstrated the possibilities of a gun turret in 1862.
