Groza-S

Groza-S. The Groza-S is a specialized bullpup assault rifle developed in Russia for suppressed, close-quarters combat. Chambered for the subsonic 9×39mm cartridge, it was designed to provide special forces units with a highly compact and integrally suppressed weapon system. Its development was closely tied to the needs of units like the Spetsnaz and the FSB for operations requiring stealth and firepower in confined spaces.

Overview

The Groza-S emerged from a series of experimental weapons developed by the Tula Arms Plant design bureau, TsKIB SOO, during the turbulent 1990s. It represents a dedicated, purpose-built evolution of the earlier OTs-14 Groza weapon family, which itself was a modular system based on components from the AKS-74U. While the original OTs-14 was conceived as a multi-role assault rifle/grenade launcher complex for the Russian Airborne Troops, the Groza-S variant was refined specifically for clandestine operations conducted by elite Russian special forces. Its primary role is to engage targets wearing body armor or behind light cover at ranges typical of urban combat, utilizing the penetrating power of the SP-5 and SP-6 ammunition.

Design and features

The Groza-S utilizes a gas-operated, rotating bolt action derived from the Kalashnikov system, ensuring reliability in harsh conditions. Its defining bullpup configuration places the action and magazine behind the trigger group, significantly reducing overall length without sacrificing barrel length, which aids in ballistic performance. A key feature is its integrated suppressor that encases a substantial portion of the barrel, effectively reducing the sound signature of the subsonic 9×39mm round to near-silent levels. The weapon typically feeds from a 20-round detachable box magazine and is equipped with a Picatinny rail on the receiver for mounting various red dot sights, night vision devices, or other optics issued to units like the Vympel Group.

Variants

The Groza-S is itself a specialized variant of the broader OTs-14 Groza family. The primary distinction from the base model is its dedicated chambering for the 9×39mm cartridge and fixed integrated suppressor, whereas the standard OTs-14 could be configured in multiple calibers including 7.62×39mm and was part of a system that could accept an underbarrel GP-25 grenade launcher. Other related experimental designs from TsKIB SOO include weapons like the AS Val and VSS Vintorez, which share the same ammunition and silent-operation concept but use a different action and layout. No significant production sub-variants of the Groza-S itself are widely documented.

Service history

The Groza-S saw limited adoption and operational use primarily during the Second Chechen War and subsequent counter-terrorism operations in the North Caucasus. It was employed by specialized units of the FSB, GRU Spetsnaz, and the Vympel and Alpha Group units during complex urban assaults and hostage-rescue scenarios. Its use was reported in notable engagements such as the Battle of Grozny (1999–2000) and the Moscow theater hostage crisis in 2002. However, it never achieved widespread service within the conventional Russian Armed Forces, remaining a niche weapon for specific direct-action missions.

Users

The primary user of the Groza-S has been the Russian Federation. Within its security apparatus, the rifle was issued to elite special operations units under the purview of the FSB and the GRU. There are no confirmed exports or adoptions of the Groza-S by foreign military or police forces, as it was produced in very limited numbers and was tailored to the specific requirements and ammunition logistics of Russian special forces. Its use remains closely associated with high-profile domestic counter-terrorism operations conducted by agencies like the FSB Special Purpose Center.
