Radetzky-class Battleships
The ''Radetzky'' class was a group of three semi-dreadnought battleships built for the Austro-Hungarian Navy between 1907 and 1910. All ships were built by the STT shipyard in Trieste. They were the last pre-dreadnoughts built by the Austro-Hungarians, and the penultimate class of any type of Austro-Hungarian battleship completed. The class comprised three ships: , , and . They were armed with four guns in two twin turrets and eight guns in four twin turrets. Commissioned only a few years before the outbreak of World War I, the ships had limited service careers. All three of the battleships conducted training cruises in the Mediterranean Sea in 1912. In 1913, they took part in an international naval demonstration in the Ionian Sea that protested the Balkan Wars. After Italy declared war on Austria-Hungary and the other Central Powers in 1915, the three ''Radetzky''-class ships bombarded coastal targets in the Adriatic Sea. After 1915, their participation in the war became minim ...

Stabilimento Tecnico Triestino
Stabilimento Tecnico Triestino (STT) ("Technical Establishment of Trieste") was a private shipbuilding company based in Trieste from the mid-19th to early 20th century, and the most important naval shipbuilding firm of the Austro-Hungarian Empire. After World War I, Trieste was annexed by Italy and the firm built naval and commercial vessels for its new host country. STT was merged with another Italian shipbuilding firm, Cantiere Navale Triestino, in 1929 to form Cantieri Riuniti dell'Adriatico (CRDA). As CRDA Trieste, its shipyards remained active well into the postwar period, becoming part of the Fincantieri group in 1984. History Austro-Hungarian ownership Stabilimento Tecnico Triestino had its origins in a private shipyard founded by Gaspare Tonello at San Marco, on the coastline west of Trieste, in 1838. In 1857, the shipyard was merged with a local manufacturer of marine engines to become STT. A second shipyard was also acquired, at San Rocco near the town of Muggia jus ...

Conning Tower
A conning tower is a raised platform on a ship or submarine, often armoured, from which an officer in charge can conn (nautical), conn (conduct or control) the vessel, controlling movements of the ship by giving orders to those responsible for the ship's engine, rudder, lines, and ground tackle. It is usually located as high on the ship as is practical, to give the conning team good visibility of the entirety of the ship, ocean conditions, and other vessels. The naval term "conn" may derive from the Middle English ''conne'' (study, become acquainted with) or French ''conduire'' from Latin ''conducere'' (conduct). Surface ships On surface ships, the conning tower was a feature of all battleships and armored cruiser, armoured cruisers from about 1860 to the early years of World War II. Located at the front end of the superstructure, the conning tower was a heavily armored cylinder, with tiny slit windows on three sides providing a reasonable field of view. Designed to shield j ...

Torpedo Boat
A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes. These were inshore craft created to counter both the threat of battleships and other slow and heavily armed ships by using speed, agility, and powerful torpedoes, and the overwhelming expense of building a like number of capital ships to counter an enemy. A swarm of expendable torpedo boats attacking en masse could overwhelm a larger ship's ability to fight them off using its large but cumbersome guns. A fleet of torpedo boats could pose a similar threat to an adversary's capital ships, albeit only in the coastal areas to which their small size and limited fuel load restricted them. The introduction of fast torpedo boats in the late 19th century was a serious concern to the era's naval strategists, i ...

Destroyer
In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or carrier battle group and defend them against a wide range of general threats. They were conceived in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unatte ...

Armored Cruiser
The armored cruiser was a type of warship of the late 19th and early 20th centuries. It was designed like other types of cruisers to operate as a long-range, independent warship, capable of defeating any ship apart from a pre-dreadnought battleship and fast enough to outrun any battleship it encountered. For many decades, naval technology had not advanced far enough for designers to produce a cruiser that combined an armored belt with the long-range and high speed required to fulfill its mission. For this reason, beginning in the 1880s and 1890s, many navies preferred to build protected cruisers, which only relied on a lightly armored deck (ship), deck to protect the vital parts of the ship. However, by the late 1880s, the development of modern rapid-fire breech-loading cannons and high-explosive shells made the reintroduction of side armor a necessity. The invention of Case-hardening, case-hardened armor in the mid-1890s offered effective protection with less weight than previou ...

Rudolf Montecuccoli
Rudolf Graf Montecuccoli degli Erri (22 February 1843 – 16 May 1922) was chief of the Austro-Hungarian Navy from 1904 to 1913 and largely responsible for the modernization of the fleet before the First World War. Overview Montecuccoli was born in Modena in 1843, a descendant of the famous imperial ''Feldmarschall'', Raimondo Montecuccoli (1609–1680). Raimondo Montecuccoli's only son died in 1698, but the title of count descended through his daughters to two lines, Austrian and Modenese. When Rudolf Montecuccoli was born, Modena was still an Austrian Habsburg possession, ruled by the house of Austria-Este. During the 1859 Second Italian War of Independence, Italian campaign, however, the last Habsburg Duke of Modena, Francis V, Duke of Modena, Francesco V, fled to Austria following the Austrian defeat at Battle of Magenta, Magenta (4 June). Italian patriots seized control, demanding union with the Kingdom of Sardinia. This was confirmed by plebiscite in March 1860, and at t ...

Adriatic Sea
The Adriatic Sea () is a body of water separating the Italian Peninsula from the Balkans, Balkan Peninsula. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Italy, Montenegro, and Slovenia. The Adriatic contains more than 1,300 islands, mostly located along its eastern coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The prevailing currents flow counterclockwise from the Strait of Otranto. Tidal movements in the Adriatic are slight, although acqua alta, larger amplitudes occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because it collects a third of the fresh water flowing into the Mediterranean, acting as a dilution basin. The surface water temperatures ...

Balkan Wars
The Balkan Wars were two conflicts that took place in the Balkans, Balkan states in 1912 and 1913. In the First Balkan War, the four Balkan states of Kingdom of Greece (Glücksburg), Greece, Kingdom of Serbia, Serbia, Kingdom of Montenegro, Montenegro and Kingdom of Bulgaria, Bulgaria declared war upon the Ottoman Empire and defeated it, in the process stripping the Ottomans of their European provinces, leaving only East Thrace, Eastern Thrace under Ottoman control. In the Second Balkan War, Bulgaria fought against the other four combatants of the first war. It also faced an attack from Kingdom of Romania, Romania from the north. The Ottoman Empire lost the bulk of its territory in Europe. Although not involved as a combatant, Austria-Hungary became relatively weaker as a much enlarged Serbia pushed for union of the South Slavs, Slavic peoples. The war set the stage for the July Crisis, July crisis of 1914 and as a prelude to the First World War. By the early 20th century, Bul ...

Mediterranean Sea
The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccation, desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The sea was an important ...
