Breda Model 35
The Breda 20/65 mod.35 (''"Breda 20 mm L/65 model 1935"''), also simply known as 20 mm Breda or Breda Model 35, among other variations, was an Italian anti-aircraft gun produced by the Società Italiana Ernesto Breda of Brescia company during the 1930s and early 1940s. It saw heavy usage during the Spanish Civil War and World War II, among other conflicts. It was designed in 1932 and adopted by the Italian armed forces in 1935, becoming one of two major 20 mm caliber anti-aircraft guns used by Italy during World War II, along with the Scotti-Isotta Fraschini 20/70 (Scotti 20 mm), both of which fired the Swiss 20x138mmB "Solothurn Long" cartridge. The Royal Italian Army designated the gun Cannone-Mitragliera da 20/65 ( "Cannon-Machinegun 20/65"), and the mount modello 35 (model 1935), or mod.35 for short. Later, a mod.39 (1939) and a mod.40 (1940) system were introduced, featuring the same gun but in new mounts. The ''"20/65"'' part of the name refers to the ca ...

Switzerland
Switzerland, officially the Swiss Confederation, is a landlocked country located in west-central Europe. It is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is geographically divided among the Swiss Plateau, the Swiss Alps, Alps and the Jura Mountains, Jura; the Alps occupy the greater part of the territory, whereas most of the country's Demographics of Switzerland, 9 million people are concentrated on the plateau, which hosts List of cities in Switzerland, its largest cities and economic centres, including Zurich, Geneva, and Lausanne. Switzerland is a federal republic composed of Cantons of Switzerland, 26 cantons, with federal authorities based in Bern. It has four main linguistic and cultural regions: German, French, Italian and Romansh language, Romansh.

HSwMS Romulus (27)
HSwMS ''Romulus'' (27) was the lead ship of her class of two destroyers that was purchased from the Royal Italian Navy in 1940 for the Royal Swedish Navy. She served during World War II and the first decades of the Cold War. The ship had been built as ''Spica'' during the 1930s. Design and description The ''Romulus''-class ships consisted of two purchased from the Royal Italian Navy in March 1940 that had been built in Italy as ''Spica'' and ''Astore''.Westerlund, p. 372 The ships displaced at standard load and at deep load. They measured long overall with a beam of , and a draft of . The ''Romulus''s were propelled by two Tosi geared steam turbines, each driving one propeller shaft using steam from a pair of Yarrow boilers. The turbines were designed to produce a total of for an intended maximum speed of . The ships carried enough fuel oil to give them a range of at . The ships' crew numbered 99.Hofsten, Waernberg & Ohlsson, p. 157 The main armament of the ''Romulus'' cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Spica-class Torpedo Boat
The ''Spica''-class was a class of torpedo boats of the (Royal Italian Navy) during World War II. These ships were built as a result of a clause in the Washington Naval Treaty, which stated that ships with a tonnage of less than 600 could be built in unlimited numbers. Thirty-two ships were built between 1934 and 1937, thirty of which entered service with Italy. Called torpedo boats due to their smaller displacement, the ''Spica''-class had armament similar to destroyers (influenced by the ) and were intended for anti-submarine operations but also had to fight aircraft and surface ships. Twenty-three vessels were lost during the war, two had been sold to the Swedish Navy in 1940 and were called destroyers until 1953, and then renamed to corvettes. Design The design work started in 1932 supervised by the general engineer Gustavo Bozzoni. Two prototypes, ''Spica'' and ''Astore'', were completed in 1935 and sold to the Swedish Navy. The hull was long, and displacement was around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Swedish Navy
The Swedish Navy () is the maritime service branch of the Swedish Armed Forces. It is composed of surface and submarine naval units – the Fleet (), formally sometimes referred to as the Royal Navy () – as well as marine units, the Amphibious Corps (). Founded under King Gustav Vasa in 1522, the Swedish navy is one of the oldest continuously serving navies in the world, celebrating its 500th anniversary in 2022. History Early Swedish kings ( 9th–14th centuries) organised a Swedish Navy along the coastline through . This involved combined rowing and sailing ships (without artillery). This system became obsolete with the development of society and changes in military technology. No later than in the 14th century, the duty to serve in was replaced by a tax. In 1427, when Sweden was part of the Kalmar Union (with Denmark and Norway), Swedish warships did however participate in the naval battle of Öresund against the Hanseatic League. It is unclear how this force was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seebach M ...

MAS (boat)
''Motoscafo armato silurante'' (torpedo-armed motorboat), alternatively ''Motoscafo antisommergibili'' (anti-submarine motorboat) and commonly abbreviated as MAS, was a class of fast torpedo-armed vessels used by the (Italian Royal Navy) during World War I and World War II. Originally, "MAS" referred to (armed motorboat SVAN), (Naval Automobile Society of Venice). The MAS were petrol-engined planing boats with displacements of 20–30 tonnes (depending on the class), a 10-man crew and armament composed of two torpedoes, heavy machine guns and occasionally a 37 mm or 20 mm cannon. In the context of the unit title (assault craft flotilla; the most famous of which was the Decima MAS of World War II), the term "MAS" is an acronym for (assault craft). World War I MAS were widely employed by ''Regia Marina'' during World War I in 1915–1918. Models used were directly derived from compact civilian motorboats, provided with petrol engines which were compact and rel ...

Corvette
A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper (or " rated") warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern roles that a corvette fulfills include coastal patrol craft, missile boat and fast attack craft. These corvettes are typically between 500 and 2,000 tons. Recent designs of corvettes may approach 3,000 tons and include a hangar to accommodate a helicopter, having size and capabilities that overlap with smaller frigates. However unlike contemporary frigates, a modern corvette does not have sufficient endurance or seaworthiness for long voyages. The word "corvette" is first found in Middle French, a diminutive of the Dutch word ''corf'', meaning a "basket", from the Latin ''corbis''. The rank " corvette captain", equivalent in many navies to " lieutenant commander", derives from the name of this type of ship. The ...

Cannone-Mitragliera Da 37/54 (Breda)
The Cannone-Mitragliera da 37/54 (Breda) was a automatic anti-aircraft gun produced by the Breda company in Italy. It was used by both the Regia Marina and the Regio Esercito The Royal Italian Army () (RE) was the land force of the Kingdom of Italy, established with the proclamation of the Kingdom of Italy. During the 19th century Italy started to unify into one country, and in 1861 Manfredo Fanti signed a decree c ... during World War II, with the former using it as the standard light anti-aircraft weapon on its battleships and cruisers. Nazi Germany used captured weapons after the surrender of Italy in 1943 as the ''3.7 cm Breda (i)''. Design The Model 1932 was water-cooled while Models 1938 and 1939 were air-cooled. The gun was fed by a flat magazine holding six rounds which could be loaded one after another to maintain a high rate of fire. It was possible to select alternate rates of fire, either 60, 90 or 120 rpm. The twin mountings for Models 1932 and 1938 were very ...

Deck (ship)
A deck is a permanent covering over a Compartment (ship), compartment or a hull (watercraft), hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the primary deck, similar to the floors of a multi-storey building, that are also referred to as decks, as are certain compartments and decks built over specific areas of the superstructure. Decks for some purposes have specific names. Structure The main purpose of the upper or primary deck is structural, and only secondarily to provide weather-tightness and support people and equipment. The deck serves as the lid to the complex box girder which can be identified as the hull. It resists Tension (physics), tension, Compression (physics), compression, and racking forces. The deck's scantling is usually the same as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Regia Marina
The , ) (RM) or Royal Italian Navy was the navy of the Kingdom of Italy () from 1861 to 1946. In 1946, with the birth of the Italian Republic (''Repubblica Italiana''), the changed its name to '' Marina Militare'' ("Military Navy"). Origins The was established on 17 March 1861 following the proclamation of the formation of the Kingdom of Italy. Just as the Kingdom was a unification of various states in the Italian peninsula, so the was formed from the navies of those states, though the main constituents were the navies of the former kingdoms of Sardinia and Naples. The new Navy inherited a substantial number of ships, both sail- and steam-powered, and the long naval traditions of its constituents, especially those of Sardinia and Naples, but also suffered from some major handicaps. Firstly, it suffered from a lack of uniformity and cohesion; the was a heterogeneous mix of equipment, standards and practice, and even saw hostility between the officers from the various f ...

Caliber
In guns, particularly firearms, but not #As a measurement of length, artillery, where a different definition may apply, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel Gauge (firearms), bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimetres, millimeters]ref name=barnes2016-p9> In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a US "45 caliber" firearm has a barrel diameter of roughly 0.45 inches (11.43mm). Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise spe ...
