10-cm-Nebelwerfer 35 ( German Nebelwerfer - lit. “fog thrower”) is a heavy German mortar of 105 mm caliber during the Second World War. The mortar was primarily intended for use with chemical munitions (to create smoke curtains), but unlike, for example, the American M2 mortar was designed from the very beginning to fire with conventional high-explosive ammunition.

Construction
The design of the mortar was completely classic, representing a doubled version of the 8 mm model 8 cm Granatwerfer 34 . Like its prototype, the mortar disassembled into three parts, which weighed two times heavier than similar parts of the 81-mm mortar (trunk - 31.7 kg, base plate - 36.3 kg and bipod - 32.2 kg), and therefore wheeled carts [1] Handkarren für 10cm Nebelwerfer (Nbf. 1) and Munitionskarren für 10 cm Nebelwerfer for transporting ammunition (both versions were foldable for transport in cars) and then Handkarren für 10cm Nebelwerfer (Nbf. 2 ) (incoherent simplified version) which could be towed or moved by calculation.
The last option had a clamp for tooling. Barrel resource was 15-18 thousand shots.
Application and Organizational Structure
The calculation consisted of a commander, three soldiers serving a mortar and three carriers of ammunition.
Starting in 1940-1941, the production of weapons was stopped due to the insufficient range of the mortar and it was replaced in the chemical forces of the Wehrmacht ( Nebeltruppen , literally - "smoke troops") on the bomber gun 10 cm Nebelwerfer 40 , and later on Nebelwerfer rocket launchers . Mortars in service were transferred to the mortar compartments. Ammunition was produced in very significant quantities until 1943. The cost of a weapon was twice as high as that of a 81 mm mortar — 1,500 marks [2] . After the invasion of the USSR, the Germans began the production of the Granatwerfer 42 mortar (a copy of the Soviet 120 mm mortar), which had much better combat characteristics, having about the same cost. The question of why the Germans stopped producing a powerful 105 mm mortar at a critical moment for the Wehrmacht - in early 1941, can be explained by overestimating the blitzkrieg concept popular among the top command, in which the main role was assigned to tanks and aircraft and the underestimation of the role of artillery as a whole.

Ammunition
The mortar used:
- 7.26 kg schwere Sprenggranate (10 cm Wgr.35 SPR) - 7.26 kg heavy mine of a high-explosive action, in which there was 1.7 kg of TNT .
- 7.26 kg schwere Rauchgranate (10 cm Wgr.35 Nb) - 7.26 kg heavy smoke mine containing 1.7 kg of chemicals.
- Kampfstoffgranate (10 cm Wgr.35 H.) is a chemical mine filled with mustard gas .
- Kampfstoffgranate (10-cm-Wgr.35 ZB) is a chemical mine (which is not widely used) filled with 0.9 kg of organic matter .
- 7.35 kg schwere, 432 mm lange Wurfgranate 37 (Wgr.37 Spr) - 7.35 kg heavy fragmentation mine, in which there were 1.28 kg of explosives.
The combat propellant charge of a 105-mm mortar consisted of a main charge (tail cartridge) weighing 15 g and four additional charges in the form of rings of 21 g each, put on the stabilizer tube. Mina left the barrel with an initial speed of up to 193 m / s and had a firing range of up to 3025 m. The spread was 65 m.
