The ShM-41 (Russian: Шлем Маска - "Helmet Mask"), also exported to East Germany as the SchM-41-M, was a Soviet mask intended for infantry use. Similar designs were used throughout the Warsaw pact, and the ShM-41 itself was exported to many Soviet countries.

Overview Edit

The mask is a typical Soviet helmet styled rubber mask. With two circular eyepieces that can fit antifog inserts but also has an integrated Tissot tubes system. The valves' housing is made out of metal which is painted dark tan and has a 40mm GOST thread. The mask was made in 5 sizes.

ShM-41 Edit

It differs from the ShM-1 mainly on the stronger valve housing, because now it is crimped on not just glued. It has an integrated Tissot tube system and antifog insert fixing rings now.

ShM-41m Edit

Differs from the previous model on the valve housing which has now double exhale valve to make a better seal. Later the valve house was modernised, it got a stronger one made of thicker metal reinforced with geometric shapes (a negative bump on the side).

ShM-41mu Edit

Just like the better-known GP-5 the u (Russian: "y") stands for the thinner rubber.

SchM-41-M Edit

East German export variant called Schutzmaske. Germany didn't produce masks so the masks were bought from the Soviet Union. It can be all the 3 previous variants.

ÜSchM-41-M Edit

Übungsschutzmaske, training variant in DDR.

Export Edit

Export for Syria, Egypt, Iraq and to other mostly arab countries. ShM-41mu with black rubber facepiece due to the sunnier and hotter weather (the black rubber is more resistant to UV).

ShMP Edit

The ShMP (ШМП, Russian: Шлем Маска Промышленный - Helmet Mask Industrial) is a designation for helmet-stlyled masks used in the industry (mainly ShM-62 and ShM-41 variants). Most of the ShM-41 masks under ShMP designation were military masks but were withdrawn from service. There is a "ШМП" stamp on the outside.

History Edit

The origin of the Soviet ShM-41 dates back to World War II, where the ShM-1 gas mask was a standard Red Army issue mask. The 'Hood Style' however dates back to World War I, pioneered as the Zelinsky Kummant gas mask. It is the most popular gas mask model in the Soviet military using the hood layout. The mask evolved and its construction held different markings. Several licensed copies of the mask were used in Warsaw Pact countries during the Cold War, including the Polish SzM-41, SzM-41M, SzM-41M KF (the MP6 and the MK-221 and MK-212/1 as well); the Bulgarian BSS-MO-4U; Hungarian 60M (Hungary also imported ShM-41 masks in small numbers as SM-41); the Czechoslovak M52 andM52M60 and the Romanian Md.52, Md.58 and S-13/S-24. The ShR-1 casualty gas mask is based on it as well.

China also copied the mask and used as Type 59, China made and other copy but with a plastic valve named Type 66. The Chinese TF-1 is also based of the ShM-41m.

Later masks such as the ShM-62 (GP-5 and its updated variant PMK-G), ShM-66mu, ShM-70, ShM-74 and ShM-2012 were inspired by it.

Markings Edit


  • "M" = Moscow
  • "С" = Saratov
  • "T" = Tambov
  • "Я" = Jakowlew


  • 1 Dot = Made between January - March
  • 2 Dots = Made between April - June
  • 3 Dots = Made between July - September
  • 4 Dots = Made Between October - December

The "y" - u - at the end of the size means it is an upgraded version with thinner rubber.

Filter Edit

Flat canisters and "coffee can" filters would be hose connected. Including: MO-2, MO-4, EO-12, EO-14, EO-16, industrial Strela Filters and various other filters depending on the user country and organisation.

Kit Edit

MO-2 Edit

The last Soviet gas mask kit issued to the army during the Second World War. It contained:

  • ShM-41 (or ShM-1) mask
  • 1939 type or Type A bag (without side pocket)
  • MO-2 filter
  • 55mm hose
  • Antifog inserts

MO-4 and MO-4u Edit

The MO-4 kit was adopted by the Soviet Army in 1946. It contained:

  • ShM-41 or ShM-41m facepiece
  • Type A bag (without side pocket)
  • MO-4 or EO-12 filter and 55mm long hose
  • antifog inserts
  • NMU insulating lenses
  • insulating sleeve (only if the mask is ShM-41)
  • IPP-51

Insulating Sleeve Edit

The insulation sleeve was a removable rubber attachment for the ShM-41, but it also fits other ShM series masks. It was made as extra protection from frost, because of the single exhale valve of the Shm-41/ShM-1. The insulation sleeve is quite rare.

RSh-4 Edit

Main article: RSh-4

It replaced the MO-4u kit in 1958. It completed with an ShM-41/ShM-41m/ShM-41mu facepieces and EO-16 filter. The Type A bag that contains the three main components, hose, filter and facepiece and and a little pocket inside for anti-fogging lenses and side pocket for IPP-51 decontamination kit. It comes with NMU insulating lenses and if the mask is a ShM-41 with the insulating sleeve as well. The RSh-4 kit is also compatible with the ShMS facepiece and the MM-1, all masks produced in the 50s and 60s.

RSch-4 Edit

In East Germany (NVA, Zivilverteidigung, Kampfgruppe) first it was issued with a simple Tragetasche 1 bag (similar to the Soviet Type A bag) in "Blumentarnmuster" camouflage pattern alongside with SchMS, MM-1 and PRWU. Then a simpler bag without camouflage and a waterproof PVC coated bag was issued (all called Tragetasche 1), to scouts the Tragetasche 1T bag in "Strichtarn" pattern was issued.

PRV Edit

Rocket refuelling kit, compatible with the ShM-41m and ShM-41mu facepieces but the most common was the ShM-41mu because the negative bump on the valve housing makes it easier to fix the hose cover.

The kit contained:

  • ShM-41m or ShM-41mu facepiece
  • hose and hose cover
  • EO-20P rocket fuel pre-filter
  • EO-65K filter
  • bag

D2gu Edit

Industrial kit. The mask can be either ShM-41, ShM-41m, ShM-41mu or ShMP with a most likely Type A bag, hose and industrial Strela Filters.

Hungarian kit Edit

The Magyar Néphadsereg (Hungarian People's Army) and Polgári védelem (Civil Defence) used the mask (mostly ShM-41) with a 60M kit instead of the 60M mask sometimes, it was called SM-41. The highest number in military service was approximately 50000, these were imported in 1962. The industry used the mask (mostly ShM-41mu, it was called sisakgázálarc - "helmet mask") in a standard industrial kit containing a 60M or 51M bag, hose (optional), industrial filter and anti-fog inserts or soap. It was used with fresh air breathing apparatuses as well.
