Frigates and submarines


FROM THE MID-19TH CENTURY, ARMORED SHIPS provided a new challenge to enemy craft. In response, huge revolving gun turrets were developed. These could fire in any direction, could be loaded from the breech very rapidly, and, instead of cannonballs, they discharged exploding shells. Modern fighting ships, like the frigate, combine heavy ship-borne armament with light helicopter weaponry. Submarines function below the surface of the sea. Their speed and ability to fire missiles from under water are their major assets. The nuclear submarine can stay under water for several years without refueling.
