Arras-class Aviso
The Arras-class, sometimes known as the ''Amiens'' class, were a series of aviso (also referred to as sloops) built for the French Navy at the end of World War I. Design and development A total of forty three fast "first-rate" avisos for convoy escort duties. These ships were ordered under 1916 and 1917 building programmes for the French Navy and all were named after places on the Western Front lines. Built in nine different military and civilian dockyards across France, The first of which, ''Arras'', entered commission May 1918. The signing of the Armistice of 11 November 1918 marked the end of the First World War, and the final thirteen planned Arras-class ships were cancelled. The remaining ships were slowly completed from 1919 to 1924. The ships were modelled after the success of British Q-ships, military ships purposely designed to resemble three-island type merchant cargo ships to deceive enemy U-boats. As such, like merchant ships they were considered roomy for their si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviso
An ''aviso'' was originally a kind of dispatch boat or "advice boat", carrying orders before the development of effective remote communication. The term, derived from the Portuguese and Spanish word for "advice", "notice" or "warning", an ''aviso'', was later adopted by the French and Portuguese navies to classify their medium-sized warships designed for colonial service. The term continued to be used in the French Navy to classify the patrol frigates until 2012, when the remaining ships of the class were reclassified as offshore patrol ships. It is equivalent to the modern use of "sloop" in other countries. Description The ''Dictionnaire de la Marine Française 1788–1792'' (by Nicolas-Charles Romme) describes ''avisos'' as "small boats designed to carry orders or dispatches". This use became obsolete with the development of means of communicating detailed information at a distance. French ''avisos'' used during World War I and World War II had displacements of 300–7 ...

Q-ship
Q-ships, also known as Q-boats, decoy vessels, special service ships, or mystery ships, were heavily armed merchant ships with concealed weaponry, designed to lure submarines into making surface attacks. This gave Q-ships the chance to open fire and sink them. The use of Q-ships contributed to the abandonment of cruiser rules restricting attacks on unarmed merchant ships and to the shift to unrestricted submarine warfare in the 20th century. They were used by the British Royal Navy and the German ''Kaiserliche Marine'' during the First World War and by the Royal Navy, the '' Kriegsmarine'', and the United States Navy during the Second World War (1939–45). Etymology Short for Queenstown in Ireland, as Haulbowline Dockyard in Cork Harbour was responsible for the conversion of many mercantile steamers to armed decoy ships in World War One, although the majority appear to have been converted in larger navy yards such as Devonport. Early uses of the concept In the 1670s, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrangel's Fleet
Wrangel's Fleet was the last remnant of the Black Sea Fleet of the Imperial Russian Navy and existed from 1920 until 1924. This squadron was a "White" (anti-communist and anti-revolutionary) unit during the Russian Civil War. It was known also as the Russian Squadron (Русская Эскадра). History In 1919, according to Peter Kenez, "Denikin acquired his naval fleet also with the aid of his foreign friends: he claimed the Russian Black Sea Fleet, which at the end of the war came into the possession of the British and French. Two minesweepers which the French gave in January 1919 became the beginning of the White navy." In 1920 the last remnants of the former Denikin's forces were confined to the Crimean Peninsula and commanded by Pyotr Nikolayevich Wrangel. In November 1920 the Bolsheviks captured the White position and the White forces evacuated to Turkey. The fleet was re-organised under the command of Rear Admiral Mikhail Alexandrovich Kedrov and was granted asylum b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aéropostale (aviation)
Aéropostale (formally, ''Compagnie générale aéropostale'') was a pioneering aviation company which operated from 1918 to 1933. It was founded in 1918 in Toulouse, France, as ''Société des lignes Latécoère'', also known as ''Lignes aeriennes Latécoère'' or simply "The Line" (''La ligne''). History Aéropostale founder Pierre-Georges Latécoère envisioned an air route connecting France to the French colonies in Africa and South America. The company's activities were to specialise in, but were by no means restricted to, airborne postal services. Between 1921 and 1927 the "Line" operated as ''Compagnie générale d'entreprises aéronautiques'' (CGEA). In April 1927 Latécoère, having troubles with its planes, damaged due to long flights to South America, decided to sell 93% of his business to another Brazilian-based French businessman named Marcel Bouilloux-Lafont. On that basis Bouilloux-Lafont then founded the ''Compagnie générale aéropostale'', better known by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interwar Period
In the history of the 20th century, the interwar period lasted from 11 November 1918 to 1 September 1939 (20 years, 9 months, 21 days), the end of the World War I, First World War to the beginning of the World War II, Second World War. The interwar period was relatively short, yet featured many significant social, political, and economic changes throughout the world. Petroleum-based energy production and associated mechanisation led to the prosperous Roaring Twenties, a time of both social mobility and economic mobility for the middle class. Automobiles, electric lighting, radio, and more became common among populations in the developed world. The indulgences of the era subsequently were followed by the Great Depression, an unprecedented worldwide economic downturn that severely damaged many of the world's largest economies. Politically, the era coincided with the rise of communism, starting in Russia with the October Revolution and Russian Civil War, at the end of World War I ...

Atlantic U-boat Campaign Of World War I
The Atlantic U-boat campaign of World War I (sometimes called the "First Battle of the Atlantic", in reference to the World War II campaign of that name) was the prolonged naval conflict between German submarines and the Allied navies in Atlantic waters—the seas around the British Isles, the North Sea and the coast of France. Initially the U-boat campaign was directed against the British Grand Fleet. Later U-boat fleet action was extended to include action against the trade routes of the Allied powers. This campaign was highly destructive, and resulted in the loss of nearly half of Britain's merchant marine fleet during the course of the war. To counter the German submarines, the Allies moved shipping into convoys guarded by destroyers, blockades such as the Dover Barrage and minefields were laid, and aircraft patrols monitored the U-boat bases. The U-boat campaign was not able to cut off supplies before the US entered the war in 1917 and in later 1918, the U-boat bases wer ...

Canon De 145 L Modele 1916 Saint-Chamond
Canon de 145 L modèle 1916 Saint-Chamond or 145 L 16 was a French heavy artillery piece designed and produced during the First World War. From 1918, many were rebored to use 155 mm shells and renamed Canon de 155 L modèle 1916 Saint-Chamond (155 L 16). A number of 145 and 155 guns were still on hand during the Second World War and served as coastal artillery in the French, Italian and German services. History The French Army had been pursuing the replacement of the Canon de 155mm L Mle 1877 de Bange gun since 1909. Spurred by the events in the Russo-Japanese war of 1904–5 it was realised that relying on an old gun which was almost immobile for long range artillery support was not a viable strategy. The French Army Artillery Technical Committee produced requirements for a de Bange replacement in November 1909. The requirements included two different guns with a range of 13 to 14 km with a maximum elevation of 35 to 40 degrees and a modern mobile carriage. It was sug ...

Hotchkiss M1929 Machine Gun
The 13.2 mm Hotchkiss machine gun model 1929, often simplified to Hotchkiss M1929 machine gun, and the like, was a heavy machine gun designed and manufactured by Hotchkiss et Cie from the late 1920s until World War II which saw service with various nations' forces, including Italy and Japan where the gun was built under license. Development In the late 1920s, Hotchkiss proposed a range of anti-aircraft automatic weapons in the 13.2, 25 and 37 mm calibers. They were all based on the same type of Gas-operated reloading, gas-operated action, similar to the one used in the 8 mm Hotchkiss Mle 1914 machine gun, which had proven extremely reliable during World War I and was still in service. This led to the production of the 13.2 mm Hotchkiss machine gun model 1929, often called the Hotchkiss M1929. Performance The Hotchkiss M1929 machine gun had a Rate of fire#Cyclic rate, cyclic rate of fire of 450 rounds per minute, but their practical sustained rate of fire wa ...

Anti-aircraft Warfare
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes Surface-to-air missile, surface based, subsurface (Submarine#Armament, submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defense, Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the World War II, Second World War, the Soviet Union, and modern NATO a ...
