Solntse-3

Solntse-3. It is a modern thermobaric weapon system developed by Russia and deployed by the Russian Armed Forces in the 2020s. The system represents a significant evolution in fuel-air explosive technology, designed for deployment from the TOS-1A heavy flamethrower system. Its development and use have been noted in contemporary conflicts, marking a continued investment in area effect munitions by the Russian military.

Overview

The Solntse-3 is a thermobaric rocket engineered to create devastating overpressure and thermal effects against fortified positions and personnel in confined spaces. It is integrated with the TOS-1A multiple rocket launcher, a vehicle based on the T-72 tank chassis. The weapon system is operated by specialized Russian Ground Forces units, often under the purview of the Radiological, Chemical and Biological Defence Troops. Its deployment is typically intended for the destruction of strongpoints, field fortifications, and light armored vehicles in support of combined arms operations.

Development and Design

The system was developed by the state-owned defense conglomerate Rostec, with primary design work conducted by the renowned ordnance bureau NPO Splav, known for systems like the BM-21 Grad. Development likely began in the 2010s, following operational analysis of earlier systems like the TOS-1 Buratino. The design focuses on enhancing the efficiency of the aerosol cloud detonation process, improving fuel mixture and ignition reliability compared to predecessors such as the MRO-A rocket. Key innovations reportedly include advanced warhead geometry and more stable propellant formulations, allowing for greater range and consistency.

Operational History

The Solntse-3 entered service with the Russian Armed Forces in the early 2020s. It was first reported in combat use during the Russian invasion of Ukraine, where TOS-1A systems were observed firing the new munitions. Its employment has been documented in battles for urban areas like Mariupol and during fighting in the Donbas region, particularly against entrenched Ukrainian Armed Forces positions. The use of such thermobaric weapons has drawn scrutiny from organizations like the United Nations and Human Rights Watch due to their severe effects in populated areas.

Technical Specifications

Fired from the TOS-1A launcher, the Solntse-3 rocket uses a solid-fuel rocket motor. While exact figures are classified, its operational range is estimated to exceed 10 kilometers, an improvement over older munitions. The warhead contains a large quantity of thermobaric explosive slurry, which upon detonation creates a sustained high-temperature blast wave with extreme overpressure. The system is designed for high lethality against targets within bunkers, trenches, and caves, with effects significantly more powerful than conventional high-explosive shells of similar size.

Variants and Related Systems

The Solntse-3 is the latest in a lineage of Russian thermobaric rockets. Its direct predecessor is the Solntsepyok rocket, also used with the TOS-1A. Other related area-denial and thermobaric systems in the Russian arsenal include the RPO-A Shmel infantry rocket and the larger ODAB-500PM aerial bomb. The foundational platform, the TOS-1 Buratino, and its upgraded TOS-1A variant, form the launch vehicle family for these munitions. Parallel development exists for smaller thermobaric grenades for use with RPG-7 type launchers.
