Mortar https://www.youtube.com/watch?v=ONDjo_jSy4Q A mortar is a weapon that fires explosive projectiles known as (mortar) bombs at low velocities, short ranges, and high-arcing ballistic trajectories. It is typically muzzle-loading with a short barrel, generally less than 15 times its caliber. Modern portable mortar It was not until the Stokes trench mortar devised by Sir Wilfred Stokes in 1915 during the First World War, that the modern mortar transportable by one person was born. In the conditions of trench warfare, there was a great need for a versatile and easily portable weapon that could be manned by troops undercover in the trenches. Stokes's design was initially rejected in June 1915 because it was unable to use existing stocks of British mortar ammunition, and it took the intervention of David Lloyd George (at that time Minister of Munitions) and Lieutenant-Colonel J. C. Matheson of the Trench Warfare Supply Department (who reported to Lloyd George) to expedite manufacture of the Stokes mortar. The weapon proved to be extremely useful in the muddy trenches of the Western Front, as a mortar round could be aimed to fall directly into trenches, where artillery shells, due to their low angle of flight, could not possibly go. The Stokes mortar was a simple weapon, consisting of a smoothbore metal tube fixed to a base plate (to absorb recoil) with a lightweight bipod mount. When a mortar bomb was dropped into the tube, an impact sensitive primer in the base of the bomb would make contact with a firing pin at the base of the tube, and detonate, firing the bomb towards the target. It could fire as many as 25 bombs per minute and had a maximum range of 800 yards firing the original cylindrical unstabilised projectile. A modified version of the mortar, which fired a modern fin-stabilised streamlined projectile and had a booster charge for longer range, was developed after World War I; this was in effect a new weapon. By World War II, it could fire as many as 30 bombs per minute, and had a range of over 2500 yards with some shell types. The French developed an improved version of the Stokes mortar as the Brandt Mle 27, further refined as the Brandt Mle 31; this design was widely copied with and without license. About 700 Stokes mortars were acquired by Poland between 1923 and 1926. These weapons were the prototype for all subsequent light mortar development around the world. Mortars today, while substantially similar in design to the Stokes mortar,are greatly improved versions; these offer a weapon that is light, adaptable, easy to operate, and yet possesses enough accuracy and firepower to provide the infantry with quality close fire support against soft and hard targets more quickly than any other means. http://en.wikipedia.org/wiki/Mortar_(weapon) Modern Mortar system http://en.wikipedia.org/wiki/M252_mortar |
