It was named after Ábrahám Ganz, the founder and the manager of the company. It is probably best known for the manufacture of tramcars, but was also a pioneer in the application of three-phase alternating current to electric railways. Ganz also made ships (''Ganz Danubius''), bridge steel structures (''Ganz Acélszerkezet'') and high-voltage equipment (''Ganz Transelektro''). In the early 20th century the company experienced its heyday, it became the third largest industrial enterprise in Kingdom of Hungary after the ''Manfréd Weiss Steel and Metal Works'' and the ''MÁVAG'' company. Since 1989, various parts of ''Ganz'' have been taken over by other companies.

German Type UB II Submarine
The UB II type submarine was a class of U-boat built during World War I by the German Imperial Navy. They were enlarged from the preceding type UB I and were more effective vessels. The boats were a single hull design with a 50-metre maximum diving depth and a 30-45 second diving time. In 1915 and 1916, 30 were built at two different shipyards. The design of type UB II addressed many of the problems apparent in the preceding type UB I class. The UB II boats featured a two-shaft drive with a much larger battery capacity and larger engines. Storage batteries were placed forward of the central diving tanks to compensate for the much heavier engine installation. The armament of the type UB II consisted of 50 cm G torpedoes launched from two bow tubes. The torpedo tubes were installed one above the other to allow for a bow design that would create optimal surface efficiency. A 5 cm gun was provided on the deck for surface use. The weight of the boat was increased to 270 ton ...

Havmanden Class Submarine (1911)
The ''Havmanden'' class was a class of six submarines built for the Royal Danish Navy from 1911 to 1914. Also later known as the A class, the boats were designed by the Austro-Hungarian firm Whitehead & Co. of Fiume. The first three submarines were built by the company, while the remaining three were constructed under license in Copenhagen. The boats were just over long and their armament consisted of two bow torpedo tubes, later supplemented with an machine gun. The boats had a single shaft and were propelled by a Fiat or M.A.N. diesel engine on the surface and two electric motors while submerged. Although there was at least one close call for the class leader during World War I, none of the six boats was sunk in service. All six boats of the class remained active in the Royal Danish Navy from their time of construction until 1928, when the first two boats were stricken. The remaining boats were all stricken by 1932. The ''Havmanden'' class served as the basis for the Austr ...

French Submarine Curie (Q 87)
SM ''U-14'' or ''U-XIV'' was a U-boat or submarine of the Austro-Hungarian Navy during the First World War. She was launched in 1912 as the French ''Curie'' (Q 87), but captured and rebuilt for service in the Austro-Hungarian Navy. At war's end, the submarine was returned to France and restored to her former name. ''Curie'' was launched in July 1912 at Toulon and completed in 1914. She measured just under long and displaced nearly on the surface and just over when submerged. At the outbreak of the First World War in August 1914, ''Curie'' was assigned to duty in the Mediterranean. In mid-December, ''Curie''s commander conceived a plan to infiltrate the Austro-Hungarian Navy's main base at Pola, but during the 20 December attempt, the vessel became ensnared in harbor defenses. Two Austro-Hungarian ships sank ''Curie'', killing three of her crew; the remainder were taken prisoner. The Austro-Hungarian Navy, which had a small and largely obsolete U-boat fleet, immediately bega ...

German Type UB I Submarine
The Type ''UB I'' submarine (sometimes known as the ''UB-1'' class) was a class of small coastal submarines (U-boats) built in Germany at the beginning of the First World War. 20 boats were constructed, most of which went into service with the German Imperial Navy.(german: Kaiserliche Marine) Boats of this design were also operated by the Austro-Hungarian Navy (Kaiserliche und Königliche Kriegsmarine ''or'' K.u.K. Kriegsmarine) and the Bulgarian Navy. In the Austro-Hungarian Navy, it was called the . Built to meet the need for small maneuverable submarines able to operate in the narrow, shallow seas off Flanders, the vessels were intended to be quickly constructed, then shipped by rail and assembled at their port of operation. The design effort began in mid-August 1914 and by mid-October the first 15 boats were ordered from two German shipyards. The German Imperial Navy subsequently ordered an additional pair of boats to replace two sold to Austria-Hungary, who ordere ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ...
