Soldato-class Destroyer
The Soldato class (also known as the Soldati class) was a class of destroyers of the Italian (Royal Navy) built by Gio. Ansaldo & C., Ansaldo of Genoa prior to the First World War. Ten were built for the ''Regia Marina'' between 1905 and 1910, while an eleventh ship was built for China but purchased by Italy before completion. They served during the First World War, where one was lost, with the remaining ships sold for scrap in the 1920s and early 1930s. Design The Soldato class was ordered from Ansaldo as an improved version of the , a class of six turtleback destroyers built for the Italian Navy by the Pattison shipyard of Naples to a modified Thornycroft design between 1899 and 1905.Chesneau and Kolesnik 1979, p. 356.Fraccaroli 1970, p. 65. The new design carried a more powerful armament than the earlier ships, with four QF 12-pounder 12 cwt naval gun, 76 mm (3 in)/40 calibre guns (capable of firing a shell to a range of at a rate of fire of 15 rounds per minute ...

Genoa
Genoa ( ; ; ) is a city in and the capital of the Italian region of Liguria, and the sixth-largest city in Italy. As of 2025, 563,947 people live within the city's administrative limits. While its metropolitan city has 818,651 inhabitants, more than 1.5 million people live in the wider metropolitan area stretching along the Italian Riviera.

Genoa was the capital of one of the most powerful maritime republics for over seven centuries, from the 11th century to 1797. Particularly from the 12th century to the 15th century, the city played a leading role in the history of commerce and trade in Europe, becoming one of the largest naval powers of the continent and considered among the wealthiest cities in the world. It was also nicknamed ''la S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Water-tube Boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum via large-bore 'downcomer tubes', where it pre-heats the feedwater supply. (In large utility boilers ...

Destroyer Classes
In navy, naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a Naval fleet, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
