Gor-class Gunboat
The ''Gor'' class was a class of two Rendel (or "flat-iron") gunboats built for the Royal Norwegian Navy between 1884 and 1887. Small, nimble vessels, they were armed with a single large-caliber gun for offensive purposes and several small, quick-firing guns for self-defense. The main gun was large for such a small craft, roughly a quarter of the length of the whole vessel, and of the same caliber as heavy battleship guns of the same era. The ''Gor'' class was likely built in the belief that the ships would be able to inflict serious damage to an opposing battleship. Service history and fate Shortly before the First World War, both vessels were rebuilt as minelayers. During this reconstruction, the heavy, large-caliber gun was replaced with a more modern 12 cm breech-loader, and one of the 37 mm guns was replaced with a more potent 57 mm (''Tyr'') or 76 mm (''Gor'') gun. With the heavy gun and ammunition removed, these diminutive vessels could carry a useful ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karljohansvern
Karjohansvern (''Karljohansvern Orlogsstasjon, KJV'') at Horten was the main base for the Royal Norwegian Navy from 1850 to 1963. Background In 1818, it was decided to establish a naval base in Horten. It was first called ''Hortens verft'', and later ''Marinens Hovedværft'' until King Oscar I of Sweden, Oscar I named it ''Carljohansværn værft'' in 1854 (after his father Charles XIV John of Sweden, Karl Johan). The shipyards was begun in 1820 and the first launch, a frigate, was in 1828. On 9 April 1940 during the Operation Weserübung, German invasion of Norway, Battle of Horten Harbour, a battle took place in the harbour when the Germans attempted to seize the base. The naval attack was repulsed, but German troops managed to outflank the Norwegians and force them to capitulate. Karljohansvern remained in German hands for the rest of World War II, while the ships operating out of it were pressed into their service. In 1953, the Norwegian Parliament determined the Navy's ...

Battleship
A battleship is a large, heavily naval armour, armored warship with a main battery consisting of large naval gun, guns, designed to serve as a capital ship. From their advent in the late 1880s, battleships were among the largest and most formidable weapon systems ever built, until they were surpassed by aircraft carriers beginning in the 1940s. The modern battleship traces its origin to the sailing ship of the line, which was developed into the steam ship of the line and soon thereafter the ironclad warship. After a period of extensive experimentation in the 1870s and 1880s, ironclad design was largely standardized by the British , which are usually referred to as the first "pre-dreadnought battleships". These ships carried an armament that usually included four large guns and several medium-caliber guns that were to be used against enemy battleships, and numerous small guns for self-defense. Naval powers around the world built dozens of pre-dreadnoughts in the 1890s and early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Decommissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before it is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing correc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Operation Weserübung
Operation Weserübung ( , , 9 April – 10 June 1940) was the invasion of Denmark and Norway by Nazi Germany during World War II. It was the opening operation of the Norwegian Campaign. In the early morning of 9 April 1940 (, "Weser Day"), German forces occupied Denmark and invaded Norway, ostensibly as a preventive manoeuvre against a planned Anglo-French Military occupation, occupation of Norway known as Plan R 4, which developed as a response to a German invasion of Norwegian territory. After the rapid occupation of Denmark, in which the Danish military was ordered to stand down as Denmark's government did not declare war with Germany, German envoys informed the governments of Denmark and Norway that Germany's forces had come to protect both countries against Anglo-French attacks. Significant differences in geography, location and climate between the two nations made the actual military operations very dissimilar. The invasion fleet's nominal landing time, (Weser Time), wa ...

Ammunition
Ammunition, also known as ammo, is the material fired, scattered, dropped, or detonated from any weapon or weapon system. The term includes both expendable weapons (e.g., bombs, missiles, grenades, land mines), and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads). The purpose of ammunition is to project a force against a selected Targeting (warfare), target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm Cartridge (firearms), cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breech-loading Weapon
A breechloader is a firearm in which the user loads the ammunition from the breech end of the barrel (i.e., from the rearward, open end of the gun's barrel), as opposed to a muzzleloader, in which the user loads the ammunition from the ( muzzle) end of the barrel. The vast majority of modern firearms are generally breech-loaders, while firearms made before the mid-19th century were mostly smoothbore muzzle-loaders. Only a few muzzleloading weapons, such as mortars, rifle grenades, some rocket launchers, such as the Panzerfaust 3 and RPG-7, and the GP series grenade launchers, have remained in common usage in modern military conflicts. However, referring to a weapon explicitly as breech-loading is mostly limited to weapons where the operator loads ammunition by hand (and not by operating a mechanism such as a bolt-action), such as artillery pieces or break-action small arms. Breech-loading provides the advantage of reduced reloading time because it is far quicker to load t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caliber (artillery)
In artillery, caliber or calibre''Caliber'' is the American English spelling, while ''calibre'' is used in British English. is the internal diameter of a gun barrel, or, by extension, a relative measure of the barrel length. Rifled barrels Rifled barrels introduce ambiguity to measurement of caliber. A rifled bore consists of alternating grooves and lands. The distance across the bore from groove to groove is greater than the distance from land to land. Projectiles fired from rifled barrels must be of the full groove-to-groove diameter to be effectively rotated by the rifling, but the caliber has sometimes been specified as the land-to-land diameter before rifling grooves were cut. The depth of rifling grooves (and the consequent ambiguity) increases in larger calibers. Steel artillery projectiles may have a forward bourrelet section machined to a diameter slightly smaller than the original land-to-land dimension of the barrel and a copper driving band somewhat larger than ...

Marine Vessel
A watercraft or waterborne vessel is any vehicle designed for travel across or through water bodies, such as a boat, ship, hovercraft, submersible or submarine. Types Historically, watercraft have been divided into two main categories. *Rafts, which gain their buoyancy from the fastening together of components that are each buoyant in their own right. Generally, a raft is a "flow through" structure, whose users would have difficulty keeping dry as it passes through waves. Consequently, apart from short journeys (such as a river crossing), their use is confined to warmer regions (roughly 40° N to 40° S). Outside this area, use of rafts at sea is impracticable due to the risks of exposure to the crew. *Boats and ships, which float by having the submergeable part of their structure exclude water with a waterproof surface, so creating a space that contains air, as well as cargo, passengers, crew, etc. In total, this structure weighs less than the water that would occupy the sa ...
