Ironclad warship in the context of "French Navy"

Industrial warfare is a period in the history of warfare ranging roughly from the early 19th century and the start of the Industrial Revolution to the beginning of the Atomic Age, which saw the rise of nation-states, capable of creating and equipping large armies, navies, and air forces, through the process of industrialization.

The era featured mass-conscripted armies, rapid transportation (first on railroads, then by sea and air), telegraph and wireless communications, and the concept of total war. In terms of technology, this era saw the rise of rifled breech-loading infantry weapons capable of high rates of fire, high-velocity breech-loading artillery, chemical weapons, armoured warfare, metal warships, submarines, and aircraft.

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 involved the two columns of opposing warships manoeuvering to volley fire with the cannons along their broadsides. In conflicts where opposing ships were both able to fire from their broadsides, the faction with more cannons firing – and therefore more firepower – typically had an advantage.

From the end of the 1840s, the introduction of steam power brought less dependence on the wind in battle and led to the construction of screw-driven wooden-hulled ships of the line; a number of purely sail-powered ships were converted to this propulsion mechanism. However, the rise of the ironclad frigate, starting in 1859, made steam-assisted ships of the line obsolete. The ironclad warship was predecessor to the 20th-century battleship, whose very designation is itself a contraction of the phrase "ship of the line of battle" or, more colloquially, "battleship of the line".

The Chincha Islands War, also known as Spanish–South American War (Spanish: Guerra hispano-sudamericana), was a series of coastal and naval battles between Spain and its former colonies of Peru, Chile, Ecuador, and Bolivia from 1865 to 1879. The conflict began with Spain's seizure of the guano-rich Chincha Islands in one of a series of attempts by Spain, under Isabella II, to reassert its influence over its former South American colonies. The war saw the use of ironclads, including the Spanish armoured frigate Numancia, the first ironclad to circumnavigate the world.

A battleship is a large, heavily armored warship with a main battery consisting of large guns, designed to serve as a capital ship. From their advent in the late 1880s, battleships were among the largest and most formidable warship types ever built, until they were surpassed by aircraft carriers beginning in the 1940s. The modern battleship traces its origin to the sailing ship of the line, which was developed into the steam ship of the line and soon thereafter the ironclad warship. After a period of extensive experimentation in the 1870s and 1880s, ironclad design was largely standardized by the British Royal Sovereign class, which are usually referred to as the first "pre-dreadnought battleships". These ships carried an armament that usually included four large guns and several medium-caliber guns that were to be used against enemy battleships, and numerous small guns for self-defense.

Naval powers around the world built dozens of pre-dreadnoughts in the 1890s and early 1900s, though they saw relatively little combat; only two major wars were fought during the period that included pre-dreadnought battles: the Spanish–American War in 1898 and the Russo-Japanese War of 1904–1905. The following year, the British launched the revolutionary all-big-gun battleship HMS Dreadnought. This ship discarded the medium-caliber guns in exchange for a uniform armament of ten large guns. All other major navies quickly began (or had already started) "dreadnoughts" of their own, leading to a major naval arms race. During World War I, only one major fleet engagement took place: the Battle of Jutland in 1916, but neither side was able to achieve a decisive result.

Pre-dreadnought battleships were sea-going battleships built from the mid- to late- 1880s to the early 1900s. Their designs were conceived before the appearance of HMS Dreadnought in 1906 and their classification as "pre-dreadnought" is retrospectively applied. In their day, they were simply known as "battleships" or else more rank-specific terms such as "first-class battleship" and so forth. The pre-dreadnought battleships were the pre-eminent warships of their time and replaced the ironclad battleships of the 1870s and 1880s.

In contrast to the multifarious development of ironclads in preceding decades, the 1890s saw navies worldwide start to build battleships to a common design as dozens of ships essentially followed the design of the Royal Navy's Majestic class. Built from steel, protected by compound, nickel steel or case-hardened steel armor, pre-dreadnought battleships were driven by coal-fired boilers powering compound reciprocating steam engines which turned underwater screws. These ships distinctively carried a main battery of very heavy guns upon the weather deck, in large rotating mounts either fully or partially armored over, and supported by one or more secondary batteries of lighter weapons on broadside.

The Brooklyn Navy Yard (originally known as the New York Navy Yard) is a shipyard and industrial complex in northwest Brooklyn in New York City, New York, U.S. The Navy Yard is located on the East River in Wallabout Bay, a semicircular bend of the river across from Corlears Hook in Manhattan. It is bounded by Navy Street to the west, Flushing Avenue to the south, Kent Avenue to the east, and the East River on the north. The site, which covers 225.15 acres (91.11 ha), is listed on the National Register of Historic Places.

The Brooklyn Navy Yard was established in 1801. From the early 1810s through the 1960s, it was an active shipyard for the United States Navy, and was also known as the United States Naval Shipyard, Brooklyn and New York Naval Shipyard at various points in its history. The Brooklyn Navy Yard produced wooden ships for the U.S. Navy through the 1870s. The shipyard built the USS Monitor, the Navy's first ironclad warship, in 1862, and it transitioned to producing iron vessels after the American Civil War in the mid-1860s. It produced some of the Navy's last pre-dreadnought battleships just prior to World War I, and it performed major repairs and overhauls of its dreadnought and post-dreadnought battleships during World War II.
