A battleship is a large armored warship with a main battery consisting of large caliber guns. It dominated naval warfare in the late 19th and early 20th centuries.
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores. The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications, open-ocean applications, and something in between, although these distinctions are more about strategic scope than tactical or operational division.
The Battle of Tsushima, also known as the Battle of Tsushima Strait and the Naval Battle of Sea of Japan in Japan, was a major naval battle fought between Russia and Japan during the Russo-Japanese War. It is the only decisive sea battle ever fought by modern steel battleship fleets and the first naval battle in which wireless telegraphy (radio) played a critically important role. It has been characterized as the "dying echo of the old era – for the last time in the history of naval warfare, ships of the line of a beaten fleet surrendered on the high seas".
A ship of the line was a type of naval warship constructed during the Age of Sail from the 17th century to the mid-19th century. The ship of the line was designed for the naval tactic known as the line of battle, which depended on the two columns of opposing warships maneuvering to volley fire with the cannons along their broadsides. In conflicts where opposing ships were both able to fire from their broadsides, the opponent with more cannons firing – and therefore more firepower – typically had an advantage. Since these engagements were almost invariably won by the heaviest ships carrying more of the most powerful guns, the natural progression was to build sailing vessels that were the largest and most powerful of their time.
Naval warfare is combat in and on the sea, the ocean, or any other battlespace involving a major body of water such as a large lake or wide river. Battles have been fought on water for more than 3,000 years.
Alfred Thayer Mahan was a United States naval officer and historian, whom John Keegan called "the most important American strategist of the nineteenth century." His book The Influence of Sea Power Upon History, 1660–1783 (1890) won immediate recognition, especially in Europe, and with its successor, The Influence of Sea Power Upon the French Revolution and Empire, 1793–1812 (1892), made him world-famous and perhaps the most influential American author of the nineteenth century.
The history of the United States Navy divides into two major periods: the "Old Navy", a small but respected force of sailing ships that was notable for innovation in the use of ironclads during the American Civil War, and the "New Navy" the result of a modernization effort that began in the 1880s and made it the largest in the world by 1943.
A blockade is the act of actively preventing a country or region from receiving or sending out food, supplies, weapons, or communications, and sometimes people, by military force. A blockade differs from an embargo or sanction, which are legal barriers to trade rather than physical barriers. It is also distinct from a siege in that a blockade is usually directed at an entire country or region, rather than a fortress or city and the objective may not always be to conquer the area.
The Battle of Quiberon Bay was a decisive naval engagement during the Seven Years' War. It was fought on 20 November 1759 between the Royal Navy and the French Navy in Quiberon Bay, off the coast of France near St. Nazaire. The battle was the culmination of British efforts to eliminate French naval superiority, which could have given the French the ability to carry out their planned invasion of Great Britain. A British fleet of 24 ships of the line under Sir Edward Hawke tracked down and engaged a French fleet of 21 ships of the line under Marshal de Conflans. After hard fighting, the British fleet sank or ran aground six French ships, captured one and scattered the rest, giving the Royal Navy one of its greatest victories, and ending the threat of French invasion for good.
Submarine warfare is one of the four divisions of underwater warfare, the others being anti-submarine warfare, mine warfare and mine countermeasures.
The 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.
Commerce raiding is a form of naval warfare used to destroy or disrupt logistics of the enemy on the open sea by attacking its merchant shipping, rather than engaging its combatants or enforcing a blockade against them.
In naval warfare, a "fleet in being" is a naval force that extends a controlling influence without ever leaving port. Were the fleet to leave port and face the enemy, it might lose in battle and no longer influence the enemy's actions, but while it remains safely in port, the enemy is forced to continually deploy forces to guard against it. A "fleet in being" can be part of a sea denial doctrine, but not one of sea control.
Sir Julian Stafford Corbett was a prominent British naval historian and geostrategist of the late 19th and early 20th centuries, whose works helped shape the Royal Navy's reforms of that era. One of his most famous works is Some Principles of Maritime Strategy, which remains a classic among students of naval warfare. Corbett was a good friend and ally of naval reformer Admiral John "Jacky" Fisher, the First Sea Lord. He was chosen to write the official history of British Naval operations during World War I.
Command of the sea is a naval military concept regarding the strength of a particular navy to a specific naval area it controls. A navy has command of the sea when it is so strong that its rivals cannot attack it directly. This dominance may apply to its surrounding waters or may extend far into the oceans, meaning the country has a blue-water navy. It is the naval equivalent of air supremacy.
Naval warfare in World War I was mainly characterized by blockade. The Allied Powers, with their larger fleets and surrounding position, largely succeeded in their blockade of Germany and the other Central Powers, whilst the efforts of the Central Powers to break that blockade, or to establish an effective counter blockade with submarines and commerce raiders, were eventually unsuccessful. Major fleet actions were extremely rare and proved less decisive.
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.
The Influence of Sea Power upon History: 1660–1783 is a history of naval warfare published in 1890 by the American naval officer and historian Alfred Thayer Mahan. It details the role of sea power during the seventeenth and eighteenth centuries, and discussed the various factors needed to support and achieve sea power, with emphasis on having the largest and most powerful fleet. Scholars considered it the single most influential book in naval strategy. Its policies were quickly adopted by most major navies, ultimately leading to the World War I naval arms race. It is also cited as one of the contributing factors of the United States becoming a great power.
The U-boat Campaign from 1914 to 1918 was the World War I naval campaign fought by German U-boats against the trade routes of the Allies. It took place largely in the seas around the British Isles and in the Mediterranean. The German Empire relied on imports for food and domestic food production and the United Kingdom relied heavily on imports to feed its population, and both required raw materials to supply their war industry; the powers aimed, therefore, to blockade one another. The British had the Royal Navy which was superior in numbers and could operate on most of the world's oceans because of the British Empire, whereas the Imperial German Navy surface fleet was mainly restricted to the German Bight, and used commerce raiders and unrestricted submarine warfare to operate elsewhere.
At the beginning of World War II, the Royal Navy was the strongest navy in the world, with the largest number of warships built and with naval bases across the globe. It had over 15 battleships and battlecruisers, 7 aircraft carriers, 66 cruisers, 164 destroyers and 66 submarines. With a massive merchant navy, about a third of the world total, it also dominated shipping. The Royal Navy fought in every theatre from the Atlantic, Mediterranean, freezing Northern routes to Russia and the Pacific ocean.
