How Ukraine Annihilated Russia's Sumy Offensive

The heralded Russian offensive into Sumy at the beginning of the summer has ended as ignominiously as all of its others.  

But Ukraine's defense of Sumy is noteworthy for the methodical way in which its armed forces repeatedly targeted Russian air defenses protecting command and logistics centers - and then destroyed the assets they were protecting, including troop concentrations. As a result, the Russians were never able to mass an effective fighting force, let alone attack at scale. The surviving Russians in Sumy are now mostly being redeployed to Pokrovsk, where they are likely to meet the same fate as their now departed comrades. JL

Euromaidan Press reports:

Ukraine crushed the Russian offensive into Sumy by cutting off supply and reinforcement routes, including roads and bridges, through continuous targeting from the air. This was made possible by systematic clearing of Russian air defenses. Buk and Tor systems, deployed to protect Russian command posts and depots, became prime targets. Ukraine' air force destroyed bases where Russian drone operators were hiding before destroying troop concentrations. On the Kursk region, the headquarters of the 155th Marine Brigade was obliterated while preparing for redeployment to Pokrovsk. High-ranking officers, including Major General Gudkov, were killed, gutting the command. Russia has begun pulling units from Sumy, a sign the offensive has failed

Today, there are interesting updates from the Sumy direction.

Here, Ukrainians have completely annihilated the Russian Sumy offensive from the air, launching devastating strikes all across the board. With even redeployed air defense assets falling victim to Western-supplied bombs, Russian operations are falling apart at the seams as each sector is meticulously targeted without mercy.

Ukrainian forces dismantle Russian air defenses before launching full-scale aerial assault

Ukraine’s armed forces have decisively crushed the Russian offensive into Sumy by cutting off their supply and reinforcement routes through continuous targeting from the air.

This success was made possible by Ukraine’s systematic clearing of the skies, with Russian air defense assets stretched across the entire frontline being repeatedly hunted down. Buk and Tor systems, deployed to protect Russian command posts and depots, became prime targets. In one case, a Russian Tor system continuously hampered Ukrainian attempts at air strikes, resulting in the air defense system becoming the target instead. In another, a Russian Tor battery malfunctioned trying to intercept a Ukrainian air strike, with the missile veering off course and striking a nearby Russian ammunition storage instead.

Additionally, Ukrainian operators used fiber-optic FPV drones to stalk and destroy Buk launchers. With these systems eliminated or suppressed, the preparation was done, and the Ukrainian strike aircraft were free to operate over the front.

Western bombs shatter Russian spearhead near Tyotkino and across Kursk

The first major blow landed near Tyotkino. Ukrainian fighters used AASM HAMMER bombs and J-dams to strike infantry groups and ammunition stores at Lokot, Tetkino, and Dronivka, while a bridge at Zabolotivka was demolished to sever supply routes.

Drone operators in Glushkovo were targeted with J-dam strikes, while troops sheltering in a grain elevator at Tyotkino were buried under rubble. Additional airstrikes leveled drone coordination centers in Korovyakivka and troop concentrations across Tyotkino, followed by hits on crossings at Zvannoye. Each wave of HAMMERs and J-dams bombs shattered Russian attempts to mass forces, leaving corpses and destroyed buildings across the Kursk villages, feeding the offensive.

Ukrainian aviation strikes deep behind the border, targeting drone hubs and infantry strongholds

Further southeast, on the Sumy side of the border, the blows continued and opened huge gaps in the Russian lines. Ukrainian aviation destroyed bases from where Russian drone operators were operating at Oleksiivka and Loknia, undermining Russian drone support capabilities, before destroying forces concentrations at Kindrativka and Oleksiivka, where Russian infantry had fortified inside of civilian buildings.

In Yunakivka, multiple bridges and troop concentrations were hit, leaving Russian soldiers buried in collapsed structures.

Major General killed as 155th Marine Brigade headquarters destroyed in Korenevo

Perhaps the most devastating blow came in the Kursk region north of the border, where the headquarters of the 155th Marine Brigade was obliterated at Korenevo while preparing for redeployment to Pokrovsk. High-ranking officers, including Major General Gudkov, were killed, gutting the command of one of Russia’s elite formations.

Additional strikes prevented the Russians from being able to fill in these gaps and leveled command centers at Kulbaki and troop concentrations in Sudzha. In each case, Ukrainian reconnaissance drones adjusted the targeting with lethal precision, ensuring no survivors and capturing the events on footage.

Belgorod strikes block Russian reinforcements from stabilizing the front

On the eastern flank, Ukrainian aircraft struck across Belgorod to prevent Russian reinforcements from stabilizing the situation and trying to hit the Ukrainian counterattacks from the side. HAMMER bombs flattened enemy garrisons in Kozynka, while J-dams destroyed drone control posts at Repyakhivka.

Bridges and positions at Guevo and Grafivka were pounded, and strikes at Kolotylivka killed entire groups of infantry. By hammering both the staging grounds and supply arteries in Belgorod and Kursk, Ukraine ensured that Russian columns advancing toward Sumy were bled dry before even reaching the border.

Russia pulls units as offensive collapses, Ukraine controls the skies

Overall, what the Russian high command once threatened as a march on Sumy city now lies in ruins, its spearheads shattered by Ukrainian airpower and its command structure gutted with the evident result of a collapsed Russian offensive.

Russia has begun pulling units from this sector to reinforce Pokrovsk, a clear sign that the offensive has failed. Ukrainian air superiority, established by dismantling Russian air defenses and exploiting gaps with precision bombs, was the decisive factor, and for the Russian command, dreams of reaching the capital of Sumy are gone. For Ukraine, the skies over the region now belong firmly to them, and their dominance has rewritten the course of the campaign.
