Nebelwerfer
The Nebelwerfer (transl. "fog launcher") was a World War II German series of weapons. They were initially developed by and assigned to the Army's Nebeltruppen. Initially, two different mortars were fielded before they were replaced by a variety of rocket launchers ranging in size from 15 to 32 centimetres (5.9 to 12.6 in). The thin walls of the rockets had the great advantage of allowing much larger quantities of gases, fluids or high explosives to be delivered than artillery or even mortar shells of the same weight. With the exception of the Balkans Campaign, Nebelwerfer were used in every campaign of the German Army during World War II. A version of the 21 cm (8.3 in) calibre system was adapted for air-to-air use against Allied bombers.
The Nebelwerfer's name, which translates as "fog launcher", had previously been given to a smoke-generating Nebelwerfer 35, and was later used for the 10 cm Nebelwerfer 40, which could deliver shells with chemical munitions, as well as high-explosive shells. The same name was then used for later rocket launcher systems. The name Nebelwerfer did remain in use for both systems, which was possibly not originally intended. The loud, shrill howling noise of the incoming rockets led Allied soldiers in the Sicily campaign to give it the nicknames "Screaming Mimi" and "Moaning Minnie".
Rudolf Nebel, a German aviator and rocket builder whose last name translates as "fog", is sometimes incorrectly named as the inventor of the Nebelwerfer artillery. Nebel did, however, develop a powder-based rocket system with the same name that he used as a fighter pilot during World War I, downing two British planes.
The lower muzzle velocity of a mortar meant that its shell walls could be thinner than those of artillery shells, and it could carry a larger payload than artillery shells of the same weight. This made it an attractive delivery system for poison gases. The U.S. Army's Chemical Warfare Service developed their 4.2-inch chemical mortar for precisely that reason and the Nebeltruppen shared that reasoning. Its first weapon was also a mortar, the 10 cm Nebelwerfer 35, which was designed in 1934.
Almost from the beginning, the army wanted more range than the 10 cm NbW 35's 3,000 metres (3,300 yd), but troop trials of two prototypes did not take place until May 1940. Neither was entirely satisfactory, but the best features of both were incorporated into the 10 cm Nebelwerfer 40. This was a very advanced breech-loading weapon with a recoil mechanism and an integral wheeled carriage. It had twice the range of its predecessor, but was eight times the weight and cost nearly ten times as much: 1,500 ℛ︁ℳ︁ vs 14,000 ℛ︁ℳ︁.
Rocket development had begun during the 1920s and reached fruition in the late thirties. This offered the opportunity for the Nebeltruppen to deliver large quantities of poison gas or smoke simultaneously. The first weapon to be delivered to the troops was the 15 cm Nebelwerfer 41 in 1940, after the Battle of France, a purpose-designed rocket with gas, smoke and high-explosive warheads. It, like virtually all German rocket designs, was spin-stabilized to increase accuracy. One very unusual feature was that the rocket motor was in the front, the exhaust venturi being about two-thirds down the body from the nose, with the intent to optimize the blast effect of the rocket as the warhead would still be above the ground when it detonated. This proved to greatly complicate manufacture for not much extra effect and it was not copied on later rocket designs. It was fired from a six-tube launcher mounted on a towed carriage adapted from that used by the 3.7 cm PaK 36 and had a range of 6,900 metres (7,500 yd). Almost five and a half million 15 cm rockets and 6,000 launchers were manufactured over the course of the war.
The 28/32 cm Nebelwerfer 41 rockets were introduced in 1941, before Operation Barbarossa. They used the same motor, but carried different warheads. The 28 centimetres (11 in) rocket had a HE warhead, while the 32 centimetres (13 in) rockets were incendiary. The maximum range for either rocket was only 2,200 metres (2,400 yd), a severe tactical drawback. Both could be fired from their wooden packing cases or a special wooden (schweres Wurfgerät 40 – heavy missile device) or tubular metal (schweres Wurfgerät 41 (sW.G. 41)) frame. Later, a towed launcher was developed that could take six rockets. Both rockets used the same launchers, but special liner rails had to be used for the 28 centimetres (11 in) rockets. A vehicular launch frame, the schwere Wurfrahmen 40 (sWu.R. 40), was also designed to improve the mobility of the heavy rockets. These were normally mounted on the sides of Sd.Kfz. 251 half-tracks, but they were also adapted for several different captured French tracked vehicles. The sWuR 40 was nicknamed the Stuka-zu-Fuß ("Stuka on Foot"). Over six hundred thousand rockets and 700 launchers, excluding the sW.G. and sWu.R. firing frames, were made during the war. In total, 345 launchers were built from 1941.
The 21 cm Nebelwerfer 42 rocket, which was introduced in 1942, had a longer range (7,850 metres (8,580 yd)) and a simpler design than the smaller 15 cm rocket. It was only made with high-explosive warheads and was fired from a five-tube launcher that used the same carriage as the smaller weapon. Liner rails were used to allow it to fire the smaller 15 cm rocket. It was also adapted for use by the Luftwaffe to break up Allied bomber formations in 1943 as the Werfer-Granate 21. Over four hundred thousand rockets and 1,400 launchers were completed.
