Naval tacticsNaval tactics and doctrine is the collective name for methods of engaging and defeating an enemy ship or fleet in battle at sea during naval warfare, the naval equivalent of military tactics on land. Naval tactics are distinct from naval strategy. Naval tactics are concerned with the movements a commander makes in battle, typically in the presence of the enemy. Naval strategy concerns the overall strategy for achieving victory and the large movements by which a commandant or commander secures the advantage of fighting at a place convenient to himself.
Naval tactics in the Age of SteamThe development of the steam ironclad firing explosive shells in the mid-19th century rendered sailing ship tactics obsolete. New tactics were developed for the big-gun Dreadnought battleships. The mine, torpedo, submarine and aircraft posed new threats, each of which had to be countered, leading to tactical developments such as anti-submarine warfare and the use of dazzle camouflage. By the end of the steam age, aircraft carriers had replaced battleships as the principal unit of the fleet.
Line of battleThe line of battle is a tactic in naval warfare in which a fleet of ships forms a line end to end. The first example of its use as a tactic is disputed—it has been variously claimed for dates ranging from 1502 to 1652. Line-of-battle tactics were in widespread use by 1675. Compared with prior naval tactics, in which two opposing ships closed on one another for individual combat, the line of battle has the advantage that each ship in the line can fire its broadside without fear of hitting a friendly ship.
Carrier battle groupA carrier battle group (CVBG) is a naval fleet consisting of an aircraft carrier capital ship and its large number of escorts, together defining the group. The CV in CVBG is the United States Navy hull classification code for an aircraft carrier. The first naval task forces built around carriers appeared just prior to and during World War II. The Imperial Japanese Navy (IJN) was the first to assemble many carriers into a single task force, known as the Kido Butai.
WarshipA warship or combatant ship is a naval ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a state. As well as being armed, warships are designed to withstand damage and are typically faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. Warships usually belong to a navy, though they have also been operated by individuals, cooperatives and corporations.
