10 cm Nebelwerfer 35 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.
10 cm Nebelwerfer 40 Almost from the beginning, the army wanted more range than the 10 cm NbW 35's , 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: vs . Almost five and a half million 15 cm rockets and 6,000 launchers were manufactured over the course of the war.
28/32 cm Nebelwerfer 41 ,
Dunkirk rocket launcher The 28/32 cm
Nebelwerfer 41 rockets were introduced in 1941, before
Operation Barbarossa. They used the same motor, but carried different warheads. The rocket had a
HE warhead, while the rockets were incendiary. The maximum range for either rocket was only , 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 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. and captured French
SOMUA MCG half-track.
Panzerwerfer To improve the mobility of the
Nebelwerfer units, a ten-tube launcher was mounted on a lightly armored Sd.Kfz. 4 "
Maultier"
half-track chassis as the 15 cm
Panzerwerfer 42
auf Selbstfahrlafette Sd.Kfz. 4/1 (based on the
Opel "
Maultier", or "Mule", half-track). Three hundred of these were produced, split evenly between launchers and ammunition carriers (which were identical except for the launcher). These were superseded in production by the 15 cm
Panzerwerfer 42
auf Schwerer Wehrmachtschlepper (
Panzerwerfer auf SWS), which had improved cross-country mobility and had greater ammunition storage than the "
Maultier". was an unguided
air-to-air rocket version of the projectile used in the
Nebelwerfer 42 and was first used in the
defense of Schweinfurt on 17 August 1943. The
Wfr. Gr. 21 was mounted on
Messerschmitt Bf 109 and
Focke-Wulf Fw 190 fighters (one launch tube under each wing) and on the
Messerschmitt Bf 110 and
Messerschmitt Me 410 heavy fighters (two launch tubes under each wing) and was the first air-to-air rocket used by the
Luftwaffe. The rockets were used to break up
Allied bomber combat box formations in order to enable more effective German fighter attacks against the scattered Allied aircraft. However, the high
drag caused by the launchers reduced the speed and maneuverability of the launching aircraft, a handicap that could prove fatal if Allied fighters were encountered. Also, the launch tube's underwing mounting setup, which usually aimed the projectile at about 15° upwards from level flight to counter the considerable
ballistic drop of the projectile in flight after launch, added to the drag problem. One experimental fitment trial program of up to 33 of the rockets, meant to be fired from a single aircraft in an upwards direction (much like the
Schräge Musik upward firing autocannon on German
Nachtjäger night fighters) was proposed for the
Heinkel He 177A as the
Grosszerstörer, mounted in the central fuselage and flying below American combat box bomber formations to down them, but the quintet of He 177A-5 airframes set aside for the
Grosszerstörer program only flew as experimental airframes, seeing no active combat deployment. ==Use in combat==
