Ukrainian forces say they have eliminated one of Russia’s most feared battlefield weapons, a TOS-1A “Solntsepyok” heavy flamethrower system valued at around 10 million dollars, in a rare strike on Russian territory. The destruction of the so‑called “Scorching Sun” near the border is being hailed in Kyiv as both a tactical success and a symbolic blow against Moscow’s efforts to terrorize front‑line troops and nearby towns.
The strike, carried out with first‑person‑view drones, appears to mark the first confirmed loss of a TOS-1A inside Russia itself, underscoring how Ukrainian long‑range and drone capabilities are evolving even as the wider war grinds into another winter of missile and drone barrages.
The strike that took out Russia’s “Scorching Sun”
According to Ukrainian accounts, the TOS-1A was hit on Russian soil in the border area of Belgorod Oblast, a region that has become a key staging ground for Russian artillery and rocket attacks into Ukraine. Video released by Ukrainian units shows multiple drones homing in on the tracked launcher and its support vehicles, followed by explosions that engulf the system in flames. Ukrainian officials describe the operation as the first time their forces have destroyed a Russian TOS-1A flamethrower in Belgorod Oblast for the, a milestone that signals a new level of reach across the border.
The TOS-1A, often referred to by its Russian nickname “Solntsepyok,” rides on a tank chassis and fires thermobaric rockets designed to obliterate fortified positions and infantry concentrations. Ukrainian sources estimate the destroyed launcher and its associated equipment at roughly 10 million dollars, a significant loss for a niche system that Russia fields in relatively small numbers. Footage and battlefield reports indicate that the strike not only disabled the main launcher but also damaged at least two tanks and other vehicles parked nearby, amplifying the impact of the attack on Russian forces massed in the area.
Inside the “Solntsepyok” and its terrifying purpose
The TOS-1A is not a conventional artillery piece but a specialized weapon built to clear trenches, bunkers, and urban strongpoints with overwhelming blast and heat. Its thermobaric rockets disperse a fuel‑air mixture that detonates in a massive pressure wave, creating what some Ukrainian soldiers call a “fire wave” that can reach as high as a nine‑story building. Russian propagandists have long promoted the system as a “machine of death,” designed to destroy fortified positions and leave no survivors in enclosed spaces, a reputation that has made it one of the most feared assets on the front.
Reports from the front describe how the TOS-1A is typically deployed close to the line of contact, using its short range to saturate a relatively small area with devastating effect. Ukrainian analysts note that this proximity makes the system vulnerable to drones and counter‑battery fire, especially as Ukrainian units refine their use of first‑person‑view munitions. In this case, Ukrainian FPVs just destroyed Russian system that could unleash fire wave high as nine-story building, turning Russia’s own emphasis on shock and awe into a vulnerability once the launcher was detected and tracked by Ukrainian operators.
How Ukrainian drones hunted the TOS-1A
Ukrainian commanders say the strike was the result of a deliberate hunt for the TOS-1A, which had been spotted operating from Russian territory near the border. In accounts shared by the unit involved, several small FPV drones were guided onto the target in sequence, first disabling support vehicles and then striking the launcher itself. The operation is being credited to a formation known as the “Black Zaporizhians,” whose pilots, identified as Fighters of the, used night‑time surveillance to locate the system and then confirmed their hits in daylight, according to a brief statement that highlighted the precision of the attack.
Military analysts in Kyiv point out that this was not only a tactical ambush but also a test of Ukraine’s ability to project drone power into Russian airspace. One report notes that the TOS-1A Solntsepyok System was hit by Ukrainian Drones Strike in Belgorod Region for the First Time, with Video evidence showing multiple impacts on the launcher and its escort vehicles. Another account emphasizes that The Ukrainian military hit a heavy flamethrower system on Russian territory in Belgorod, inside the Russian Federation, underscoring how the front is no longer confined to Ukrainian soil as long‑range drones and reconnaissance assets extend Kyiv’s reach.
Ukrainian sources add that the same strike package may have involved as many as 38 individual drone sorties, a figure that reflects both the redundancy built into such missions and the growing industrial base behind Ukraine’s drone fleet. The unit that released the footage, the 72 mechanized brigade, highlighted how small, relatively cheap FPV platforms can now threaten high‑value Russian assets far behind the immediate front line, a trend that is reshaping how both sides think about survivability and concealment for their most prized systems.
Why this loss matters for Russia’s winter campaign
The destruction of the TOS-1A comes as Russia intensifies its own aerial campaign against Ukrainian cities and infrastructure. Moscow has resumed large‑scale drone and missile strikes after a brief lull, targeting energy facilities and urban centers across Ukraine. One recent wave was described as a mass attack that ended a pause in long‑range strikes, with Moscow drawing on both domestically produced drones and components sourced through foreign networks to sustain the pressure.
Another assessment calls the latest barrage Russia’s heaviest attack on Ukraine’s energy sector in 2026, with at least 54 missiles and drones launched in a single coordinated operation that struck power plants and grid nodes across multiple regions. That report, attributed to Alyona Kyrychenko, notes that Russia is seeking to exploit winter conditions to maximize the impact on heating and electricity supplies, a tactic that has become a grim hallmark of the conflict. In this context, the loss of a TOS-1A on Russian soil is more than a single battlefield setback, it is a reminder that Ukraine can still inflict painful blows on the systems Russia relies on to sustain its offensive pressure.
A shifting battlefield as diplomacy stalls
The strike on the “Scorching Sun” also lands against a backdrop of uncertain diplomacy and deepening winter hardship. International attention has turned to talks in Abu Dhabi, where negotiators are probing whether the Kremlin is prepared to consider any form of compromise. One analysis frames the question bluntly, asking What might signal that the Russian leadership is serious about peace, while noting that front‑line conditions remain brutal and that temperatures in some combat zones have dropped below minus 20 degrees Celsius.

On the ground, the war shows few signs of slowing. Reports from KYIV describe how Russia resumes large-scale Ukraine strikes in freezing weather, with BSS citing AFP to underline that the latest wave was described as the most powerful attack this year on Ukraine’s energy grid. That account stresses that critical infrastructure is being hit precisely when civilians are most vulnerable due to the frigid temperatures, a pattern that mirrors earlier winters of the conflict. Against this backdrop, Ukraine’s ability to reach into Russian territory and destroy a TOS-1A Solntsepyok System is both a tactical achievement and a message: even as Russia, Ukraine, and their backers weigh diplomatic options, the technological race on the battlefield is still accelerating, and high‑value weapons like the “Scorching Sun” are no longer safe simply because they sit on the far side of the border.
