Naval 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.
Modern naval tactics are based on tactical doctrines developed after World War II, following the obsolescence of the battleship and the development of long-range missiles. Since there has been no major naval conflict since World War II, apart from the Indo-Pakistani Naval War of 1971 and the Falklands War, many of these doctrines reflect scenarios developed for planning purposes. Critics argue that the collapse of the Soviet Union and the subsequent reduction in the size and capabilities of the Russian Navy renders most such fleet-on-fleet scenarios obsolete.
A central concept in Western modern naval fleet warfare is battlespace: a zone around a naval force within which a commander is confident of detecting, tracking, engaging and destroying threats before they pose a danger. As in all forms of warfare, a critical objective is to detect the enemy while avoiding detection.
The open sea provides the most favorable battlespace for a surface fleet. The presence of land and the topography of an area compress the battlespace, limit the opportunities to maneuver, make it easier for an enemy to predict the location of the fleet, and make the detection of enemy forces more difficult. In shallow waters, the detection of submarines and mines is especially problematic.
One scenario that was the focus of American and NATO naval planning during the Cold War was a conflict between two modern and well equipped fleets on the high seas, the clash of the United States/NATO and the Soviet Union/Warsaw Pact.

La lutte anti-sous-marine (ASM) désigne l'ensemble des tactiques de combat et de protection contre la menace représentée par les sous-marins. Elle met en œuvre plusieurs moyens complémentaires : navires de surface, des escorteurs, équipés de sonars (essentiellement des frégates et des corvettes) ; avion de patrouille maritime ; hélicoptères ASM ; sous-marins d'attaque. Le dispositif est dirigé depuis un des escorteurs anti sous-marin, à bord duquel est embarqué le commandant de l'opération de lutte anti-sous-marine.
Sailing ship tactics were the naval tactics employed by sailing ships in contrast to galley tactics employed by oared vessels. This article focuses on the period from c. 1500 to the mid-19th century, after which sailing warships were replaced with steam-powered ironclads. Since ancient times, war at sea had been fought much as on land: with melee weapons and bows and arrows, but on floating wooden platforms rather than battlefields. Though the introduction of guns was a significant change, it only slowly changed the dynamics of ship-to-ship combat.
The 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.
