21 Cm Haubitze M1891
The 21 cm Haubitze M1891 or ''(21 cm Howitzer Model 1891)'' in English was a fortress gun built by Krupp that armed the forts of several European countries before World War I. Two countries that bought the M1891 were Belgium and Romania. In Belgian service it was designated ''Obusier de 21c.A.'' and in Romanian service it was designated ''Obuzierul Krupp, calibrul 210 mm, model 1891''. History During the second half of the 1800s, several military conflicts changed the balance of power in Europe and set off an arms race leading up to World War I. A company that profited from this arms race was the Friedrich Krupp Company of Essen Germany and several European countries were armed with Krupp artillery. Some customers like Belgium, Italy, Romania, and Russia imported and built Krupp designs under license while others like the Ottoman Empire and Bulgaria lacking industrial capacity imported Krupp weapons. In addition to Krupp, one of the most profitable companies during this period wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Howitzer
A howitzer () is a long- ranged weapon, falling between a cannon (also known as an artillery gun in the United States), which fires shells at flat trajectories, and a mortar, which fires at high angles of ascent and descent. Howitzers, like other artillery equipment, are usually organized in a group called a battery. Howitzers, together with long-barreled guns, mortars, and rocket artillery, are the four basic types of modern artillery. Mortars fire at angles of elevation greater than 45°, and are useful for mountain warfare because the projectile could go over obstacles. Cannons fire at low angles of elevation (<45°), and the projectile lands much faster at its target than it would in the case of a mortar. But the cannon is not useful if there is an obstacle like a hill/wall in front of its target. Etymology The English word ''howitzer'' comes from the Czech word , from , 'crowd', and is in turn a borrowing from the Middle High German word or (mode ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
25 Cm Schwerer Minenwerfer
The 25 cm schwerer Minenwerfer (heavy mine launcher), often abbreviated as 25 cm sMW, was a heavy mine shell launching trench mortar developed for the Imperial German Army in the first decade of the 20th century. Design and development It was developed for use by engineer troops after the Siege of Port Arthur during the Russo-Japanese War of 1904–05 illustrated the usefulness of this class of weapon in destroying bunkers and fortifications immune to normal artillery. The 25 cm schwerer Minenwerfer was a muzzle-loading, rifled mortar that had a hydro-spring type recoil system. It fired either a shell or a mine shell; both containing far more explosive filler than ordinary artillery ammunition of the same caliber. The low muzzle velocity allowed for thinner shell walls, hence more space for filler for the same weight shell. The low velocity also allowed the use of explosives like ammonium nitrate–carbon that were less shock-resistant than TNT, which was in shor ...
