The Sfera (Russian:Сфера) (Sphere), officially called STSh-81, are bullet resistant crash helmet style helmets of titanium and steel manufactured with protective GOST ratings of 1 and 2 respectively. They are worn by the Internal Troops of the Interior Ministry in the Soviet Union and its successor state Russia, these helmets continue to be used today by the police and special purpose troops.
The SSSh-94 is the successor to the STSh-81 and is currently produced by Classcom. Outwardly similar to its predecessor, the introduction of steel armor allowed for improved quality and protection at the cost of additional weight (The STSh-81 weighs 2.4kg while the SSSh-94 weighs 3.3kg). The steel used in the SSSh-94 is of the same type as that used in the Maska series of helmets.
In both examples, the helmet design consists of three plates: two round ones on the sides of the head, and one bow-shaped one that sits on top, stretching from the neck to the forehead. These plates are kept together by a padded cover, with drawstring to adjust the size and fit of the plates. The helmet may also be camouflaged with a helmet cover which appears in such patterns as VSR and Flora.
In addition to the original Russian helmets, Ukrainian varieties exist.
