Dreadnought in the context of "SMS Schleswig-Holstein"

Modern warfare is warfare that diverges notably from previous military concepts, methods, and technology, emphasizing how combatants must modernize to preserve their battle worthiness. As such, it is an evolving subject, seen differently in different times and places. In its narrowest sense, it is merely a synonym for contemporary warfare.

In its widest sense, it includes all warfare since the "gunpowder revolution" that marks the start of early modern warfare, but other landmark military developments have been used instead, including the emphasis of artillery marked by the Crimean War, the military reliance on railways beginning with the American Civil War, the launch of the first dreadnought in 1905, or the use of the machine gun, aircraft, tank, or radio in World War I.

SMS Schleswig-Holstein (pronounced [ˌʃleːsvɪç ˈhɔlʃtaɪn] ) was the last of the five pre-dreadnought Deutschland-class battleships built by the German Kaiserliche Marine. The ship, named for the province of Schleswig-Holstein, was laid down in the Germaniawerft dockyard in Kiel in August 1905 and commissioned into the fleet nearly three years later. The ships of her class were already outdated by the time they entered service, being inferior in size, armor, firepower and speed to the new generation of dreadnought battleships.

Schleswig-Holstein fought in both World Wars. During World War I, she saw front-line service in II Battle Squadron of the High Seas Fleet, culminating in the Battle of Jutland on 31 May – 1 June 1916. Schleswig-Holstein saw action during the engagement, and was hit by one large-caliber shell. After the battle, Schleswig-Holstein was relegated to guard duty in the mouth of the Elbe River before being decommissioned in late 1917. As one of the few battleships permitted for Germany by the terms of the Treaty of Versailles, Schleswig-Holstein was again pressed into fleet service in the 1920s. In 1935, the old battleship was converted into a training ship for naval cadets.

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.

The Deutschland class was a group of five pre-dreadnought battleships built for the German Kaiserliche Marine (Imperial Navy), the last vessels of that type to be built in Germany. The class comprised Deutschland, the lead ship, Hannover, Pommern, Schlesien, and Schleswig-Holstein. The ships closely resembled those of the preceding Braunschweig class, but with stronger armor and a rearranged secondary battery. Built between 1903 and 1908, they were completed after the launch of the revolutionary British all-big-gun battleship HMS Dreadnought in 1906. As a result, they were obsolescent before entering service. The ships nevertheless saw extensive service in the High Seas Fleet, Germany's primary naval formation, through the late 1900s and early 1910s, when they were used for training, which included overseas cruises.

Following the start of World War I in July 1914, the German fleet adopted a strategy of raids on the British coast, which the five Deutschland-class ships supported. These operations culminated in the Battle of Jutland on 31 May – 1 June 1916, where all five ships saw action, despite their marked inferiority to British dreadnoughts. Regardless, they intervened to protect the battered German battlecruisers from their British counterparts, allowing them to escape. In the confused night actions, Pommern was torpedoed and sunk by a British destroyer. After the battle, the four surviving ships were removed from front-line service and used for coastal defense through mid-1917. Thereafter, Hannover alone remained on patrol duty, while the rest were used as barracks or training ships. After Germany's defeat, the Treaty of Versailles permitted the postwar navy to retain several old battleships for coastal defense, including the four Deutschland-class ships.

The High Seas Fleet (German: Hochseeflotte) was the battle fleet of the German Imperial Navy and saw action during the First World War. In February 1907, the Home Fleet (Heimatflotte) was renamed the High Seas Fleet. Admiral Alfred von Tirpitz was the architect of the fleet; he envisioned a force powerful enough to challenge the Royal Navy. Kaiser Wilhelm II, the German Emperor, championed the fleet as the instrument by which he would seize overseas possessions and make Germany a global power. By concentrating a powerful battle fleet in the North Sea while the Royal Navy was required to disperse its forces around the British Empire, Tirpitz believed Germany could achieve a balance of force that could seriously damage British naval hegemony. This was the heart of Tirpitz's "Risk Theory", which held that Britain would not challenge Germany if the latter's fleet posed such a significant threat to its own.

The primary component of the Fleet was its battleships, typically organized in eight-ship squadrons, though it also contained various other formations, including the I Scouting Group. At its creation in 1907, the High Seas Fleet consisted of two squadrons of battleships, and by 1914, a third squadron had been added. The dreadnought revolution in 1906 greatly affected the composition of the fleet; the twenty-four pre-dreadnoughts in the fleet were rendered obsolete and required replacement. Enough dreadnoughts for two full squadrons were completed by the outbreak of war in mid-1914; the eight most modern pre-dreadnoughts were used to constitute a third squadron. Two additional squadrons of older vessels were mobilized but later disbanded.

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.

The arms race between Great Britain and Germany that occurred from the last decade of the nineteenth century until the advent of World War I in 1914 was one of the intertwined causes of that conflict. While based in a bilateral relationship that had worsened over many decades, the arms race began with a plan by German Admiral Alfred von Tirpitz in 1897 to create a fleet in being to force Britain to make diplomatic concessions; Tirpitz did not expect the Imperial German Navy to defeat the Royal Navy.

With the support of the Kaiser Wilhelm II, Tirpitz began advancing a series of laws to construct an increasing number of large surface warships. The construction of HMS Dreadnought in 1906 prompted Tirpitz to further increase the rate of naval construction. While some British observers were uneasy at German naval expansion, alarm was not general until Germany's naval bill of 1908. The British public and political opposition demanded that the Liberal government meet the German challenge, resulting in the funding of additional dreadnoughts in 1910 and escalating the arms race.

Dreadnoughtus is a genus of titanosaurian sauropod dinosaur containing a single species, Dreadnoughtus schrani. It is known from two partial skeletons discovered in Upper Cretaceous (Campanian to Maastrichtian, approximately 76–70 million years ago) rocks of the Cerro Fortaleza Formation in Santa Cruz Province, Argentina. It is one of the largest terrestrial vertebrates known, with the immature type specimen measuring 26 metres (85 ft) in total body length and weighing 48–49 metric tons (53–54 short tons) (the greatest mass of any land animal that can be calculated with reasonable certainty).

Dreadnoughtus is known from more complete skeletons than any other gigantic titanosaurian. Drexel University paleontologist Kenneth Lacovara, who discovered the genus, chose the name Dreadnoughtus, which means "fears nothing", stating "I think it's time the herbivores get their due for being the toughest creatures in an environment." Specifically, the name was inspired by the dreadnought, an extremely influential early 20th-century battleship type, known for revolutionarily outclassing (and thus supposedly never needing to fear) the smaller, weaker battleships that came before.
