QF 6 Pounder Hotchkiss
The Ordnance QF Hotchkiss 6 pounder gun Mk I and Mk II or QF 6 pounder 8 cwt were a family of long-lived light naval guns introduced in 1885 to defend against new, small and fast vessels such as torpedo boats and later submarines. There were many variants produced, often under license which ranged in length from 40 to 58 calibers, but 40 caliber was the most common version. 6-pounders were widely used by the navies of a number of nations and often used by both sides in a conflict. Due to advances in torpedo delivery and performance, 6-pounder guns were rapidly made obsolete and were replaced with larger guns aboard most larger warships. This led to their being used ashore during World War I as coastal defense guns, the first tank guns and as anti-aircraft guns, whether on improvised or specialized HA/LA mounts. During World War II 6-pounder guns were put back in service to arm small warships and as coastal defense guns. The last ships to carry 6-pounders were the Aegir-cl ...

Armstrong Whitworth
Sir W G Armstrong Whitworth & Co Ltd was a major British manufacturing company of the early years of the 20th century. With headquarters in Elswick, Newcastle upon Tyne, Armstrong Whitworth built armaments, ships, locomotives, automobiles and aircraft. The company was founded by William Armstrong in 1847, becoming Armstrong Mitchell and then Armstrong Whitworth through mergers. In 1927, it merged with Vickers Limited to form Vickers-Armstrongs, with its automobile and aircraft interests purchased by J D Siddeley. History In 1847, the engineer William George Armstrong founded the Elswick works at Newcastle, to produce hydraulic machinery, cranes and bridges, soon to be followed by artillery, notably the Armstrong breech-loading gun, with which the British Army was re-equipped after the Crimean War. In 1882, it merged with the shipbuilding firm of Charles Mitchell to form Armstrong Mitchell & Company and at the time its works extended for over a mile (about 2 km) along th ...

Bofors 40 Mm Automatic Gun L/70
The Bofors 40 mm Automatic Gun L/70, (Bofors 40 mm L/70, Bofors 40 mm/70, Bofors 40/70 and the like), is a multi-purpose autocannon developed by the Swedish arms manufacturer AB Bofors (today BAE Systems Bofors) during the second half of the 1940s as a modern replacement for their extremely successful World War II-era Bofors 40 mm L/60 gun-design. It was initially intended as a dedicated anti-aircraft weapon, being sold as ''Bofors 40 mm Automatic A.A. Gun L/70'', but has since its conception been redeveloped into a dedicated multi-purpose weapon capable of firing both sabot projectiles and programmable ammunition. The Bofors 40 mm L/70 design never achieved the same popularity and historical status as the original L/60 design but has still seen great export and popularity to this day, having been adopted by around 40 different nations and even being accepted as NATO-standard in November 1953. It is still being produced and sold (since March 2005 by BAE S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pre-dreadnought Battleship
Pre-dreadnought battleships were sea-going battleships built between the mid- to late- 1880s and 1905, before the launch of in 1906. The pre-dreadnought ships replaced the ironclad battleships of the 1870s and 1880s. Built from steel, protected by case-hardened steel armour, and powered by coal-fired triple-expansion steam engines, pre-dreadnought battleships carried a main battery of very heavy guns in fully enclosed rotating turrets supported by one or more secondary batteries of lighter weapons. In contrast to the multifarious development of ironclad warships in preceding decades, the 1890s saw navies worldwide start to build battleships to a common design as dozens of ships essentially followed the design of the Royal Navy's . The similarity in appearance of battleships in the 1890s was underlined by the increasing number of ships being built. New naval powers such as Germany, Japan, the United States, and to a lesser extent Italy and Austria-Hungary, began to establish ...

Brazilian Cruiser Almirante Barroso (1896)
''Almirante Barroso'' was a protected cruiser operated by the Brazilian Navy between 1896 and 1931. It was the first Brazilian ship to have radio telegraphy. It represented Brazil in Argentina and Chile, in addition to other commissions. It was one of the government ships that faced the rebels in the Revolt of the Lash. It was decommissioned in 1931. Construction and design ''Almirante Barroso'' was built at the Armstrong Whitworth & Co. shipyards in Elswick, England. The keel was laid in September 1895 and the launch and commissioning took place on 25 August 1896. It was the third vessel to bear the name ''Almirante Barroso'', in honor of admiral Francisco Manuel Barroso, Baron of Amazonas. The ship was constructed with 5/8 inch steel plates. It had 14 watertight compartments, an armored deck, a Cofferdam-type armored belt to protect vital areas, a double hull, a battering ram and two masts. It displaced 3,437 t and measured 107.989 m in total length; 100.580 m in length betwee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marshal Deodoro-class Coastal Defense Ship
The ''Deodoro'' class were two French-designed and built coastal defense battleships built for the Brazilian Navy in the late 1890s. Upon their completion, ''Scientific American'' called them small vessels of a type "built only for second-rate naval powers," but also noted that it was a "wonder ... so much armor and armament could be carried" on a ship of its size. They served the Brazilian Navy as its only modern armored warships until the arrival of two dreadnoughts in 1910.Lyon, p. 407 About The ships had a low freeboard and long superstructures with single-gun main turrets arranged at each end. Their secondary batteries were also mounted at each end of the superstructure, albeit in casemates in each corner. All used British Armstrong guns. In 1912, both ships were overhauled with new propulsion and armament. In 1924, Brazil sold ''Marshal Deodoro'' to the Mexican Navy The Mexican Navy is one of the two independent armed forces of Mexico. The actual naval forces are called ...

Protected Cruiser
Protected cruisers, a type of naval cruiser of the late-19th century, gained their description because an armoured deck offered protection for vital machine-spaces from fragments caused by shells exploding above them. Protected cruisers resembled armored cruisers, which had in addition a belt of armour along the sides. Evolution From the late 1850s, navies began to replace their fleets of wooden ships-of-the-line with armoured ironclad warships. However, the frigates and sloops which performed the missions of scouting, commerce raiding and trade protection remained unarmoured. For several decades, it proved difficult to design a ship which had a meaningful amount of protective armour but at the same time maintained the speed and range required of a "cruising warship". The first attempts to do so, armored cruisers like , proved unsatisfactory, generally lacking enough speed for their cruiser role. During the 1870s the increasing power of armour-piercing shells made armou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Defense Ship
Coastal defence ships (sometimes called coastal battleships or coast defence ships) were warships built for the purpose of Littoral (military), coastal defence, mostly during the period from 1860 to 1920. They were small, often cruiser-sized warships that sacrificed speed and range for armour and armament. They were usually attractive to nations that either could not afford full-sized battleships or could be satisfied by specially designed shallow-draft vessels capable of littoral operations close to their own shores. The Nordic countries and Thailand found them particularly appropriate for their island-dotted coastal waters. Some vessels had limited Blue-water navy, blue-water capabilities; others operated in Maritime geography#Riverine, rivers. The coastal defence ships differed from earlier Monitor (warship), monitors by having a higher Freeboard (nautical), freeboard and usually possessing both higher speed and a secondary armament; some examples also mounted casemated gun ...

ARA General Belgrano (1896)
ARA ''General Belgrano'' was a armoured cruiser of the Argentine Navy. The ship was built in Italy, along with three sister ships also for Argentina ( ''Garibaldi'', ''Pueyrredón'' and ''San Martín''). The vessel was the first to have been named after the Argentine founding father Manuel Belgrano (1770–1820). The ship was laid down in 1896 and served on the Argentine Navy until she was stricken on 8 May 1947. Service history The cruiser was built at the Cantiere Navale Fratelli Orlando, in Livorno, where her hull was laid down in 1896 and launched on 25 July 1897. She was purchased in 1898 by the government of Argentina, engaged in a diplomatic conflict with Chile. After testing of machinery and artillery, ''General Belgrano'' entered service on 8 October 1898, departing the same day entered the port of Genoa, under the command of Captain Emilio Barilari, arriving at their destination in Mar del Plata, on November 6 of that year.

Argentine–Chilean Naval Arms Race
In the late nineteenth and early twentieth centuries, the South American nations of Argentina and Chile engaged in an expensive naval arms race to ensure the other would not gain supremacy in the Southern Cone. Although the Argentine and Chilean navies possessed insignificant naval forces in the 1860s, with zero and five warships, respectively, Argentina's concern over a strong Imperial Brazilian Navy and the Chilean war against Spain caused them to add capable warships to their fleets in the 1870s. During this time, diplomatic relations between Argentina and Chile soured due to conflicting boundary claims, particularly in Patagonia. By the beginning of the 1880s, after the War of the Pacific, the Chilean government possessed possibly the strongest navy in the Americas. They planned to add to it with an 1887 appropriation for one battleship, two protected cruisers, and two torpedo gunboats. Argentina responded a year later with an order for two battleships of its own. The naval ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
