Vale-class Gunboat
The ''Vale'' class was a class of five Rendel (or "flat-iron") gunboats built for the Royal Norwegian Navy between 1874 and 1878. Small, nimble vessels, they were armed with a single large calibre muzzle-loading gun for offensive purposes and several small, quick firing guns for self-defence. Service history Shortly before the First World War, the five vessels were rebuilt as minelayers. During this rebuild, the heavy muzzle-loading gun was replaced with a more modern 12 cm breech-loader, and on ''Nor'' and ''Vidar'' one of the 37 mm guns was replaced with a more potent 47 mm gun. Since the heavy gun and ammunition was removed, these diminutive vessels could carry a useful number of mines. All vessels were kept in service until the German invasion in 1940 and with the exception of ''Uller'', which was sunk by the Royal Norwegian Navy Air Service after capture by the Germans, they all spent the remainder of the war in German hands. After the Second World War ...

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 ...

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 n ...

Gunboat
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies. History Pre-steam era In the age of sail, a gunboat was usually a small undecked vessel carrying a single smoothbore cannon in the bow, or just two or three such cannons. A gunboat could carry one or two masts or be oar-powered only, but the single-masted version of about length was most typical. Some types of gunboats carried two cannon, or else mounted a number of swivel guns on the railings. The small gunboat had advantages: if it only carried a single cannon, the boat could manoeuvre in shallow or restricted areas – such as rivers or lakes – where larger ships could sail only with difficulty. The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and quick to build, naval forces favoured swarm ...

Minelayer
A minelayer is any warship, submarine, military aircraft or land vehicle deploying explosive mines. Since World War I the term "minelayer" refers specifically to a naval ship used for deploying naval mines. "Mine planting" was the term for installing controlled mines at predetermined positions in connection with coastal fortifications or harbor approaches that would be detonated by shore control when a ship was fixed as being within the mine's effective range. An army's special-purpose combat engineering vehicles used to lay landmines are sometimes called "minelayers". Etymology Before World War I, mine ships were termed mine planters generally. For example, in an address to the United States Navy ships of Mine Squadron One at Portland, England, Admiral Sims used the term "mine layer" while the introduction speaks of the men assembled from the "mine planters". During and after that war the term "mine planter" became particularly associated with defensive coastal fortifi ...

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 ...
