REPORT: Ukraine-Russia, Summer 2026 — the Attrition Moscow Is Losing but Refuses to Acknowledge

Introduction: A War Russia Cannot Win and Will Not Lose

Summer 2026 on the Ukrainian front: numbers that do not lie

In the direction of Kostyantynivka, in the Donbas, Russian forces absorb approximately 53 casualties per day for territorial gains limited to minor group infiltrations. Ukrainian forces, on their side, suffer approximately 3 casualties per day there. That loss ratio of roughly 18:1 in Ukraine's favor is not a decisive victory — but it is a brutal arithmetical demonstration of the comparative sustainability of the two military strategies. These figures come from the Institute for the Study of War (ISW) assessment of June 23, 2026, one of the most rigorous and best-sourced analyses of the state of the conflict.

It is in this context that President Putin and Kremlin officials reiterated, according to the same report, Russia's commitment to achieving its « original war objectives » — the complete capitulation of Ukraine. That gap between public discourse and battlefield reality is one of the most striking features of the war in summer 2026. Moscow proclaims its inevitable victory while its troops die at a rate eighteen times greater than their adversaries in some sectors. That is not strategy. That is propaganda.

What Ukraine is striking, and why it matters

On the night of June 22 to 23, 2026, Ukrainian forces struck more than 60 Russian targets in Crimea in a single night. The identified targets included three Orion reconnaissance drones, a Nebo-U radar, fuel tanks at the Kerch thermal power station, a Pantsir-S1 system, an S-300 launcher, a ZU-23 cannon, an electrical substation — and the railway bridge over the North Crimea Canal near Rozdolne, destroyed. That same night, more than 60 additional targets were struck. Russian logistical communication lines in Crimea are fragmenting under these repeated strikes, creating supply shortages that are beginning to affect the Russian war effort in the peninsula.

This deep strike campaign is not symbolic — it is strategic. Crimea, presented by the Kremlin as « returned to the motherland » and inviolable, finds itself short of fuel, without power in several districts, with its rail axes targeted and its Chonhar bridge partially destroyed. Ukrainian Defense Minister Mykhailo Fedorov declared that Ukraine is effectively « isolating » Crimea, which could become a logistical island. In an oil-exporting country, having regions short of fuel because of Ukrainian strikes is a first-rate strategic catastrophe.

Russia's Fuel Crisis: A Documented Ukrainian Strategic Effect

Eight major Russian refineries struck in May 2026

In May 2026, Ukrainian forces struck eight of Russia's ten largest refineries. That figure is not an estimate — it is documented by satellite imagery analysts and industry reports. The result: Russian oil production fell by 13% compared to previous levels, the worst outcome since the start of the invasion in 2022. Russia, the world's third-largest oil producer, had to consider importing fuel by sea to manage a gasoline shortage in an oil-exporting country. That paradox is the most concrete measure of the effectiveness of Ukraine's strategy of deep economic strikes.

The Moscow refinery in the Kapotnya district, which supplies up to 40% of the capital region's fuel and processes more than 11.6 million tons of crude oil per year, was struck on June 16 and 18, 2026. It is unlikely to resume production before 2027 according to industry sources cited by Reuters. Regions as distant as Kamchatka and Novosibirsk are expected to face fuel shortages by end of June or early July. Russian Deputy Prime Minister Alexander Novak described the situation as « difficult but manageable » — a formulation whose second part sounds more like hope than reality.

The effect on Russian military logistics in Crimea and the Donbas

The impact of Ukrainian strikes on Russian military logistics is documented in granular detail in the ISW report of June 23, 2026. In the direction of Hulyaipole, Russian supplies from Crimea have been « significantly reduced » due to strikes on communication lines, including the Chonhar bridge. Russian soldiers must now walk 50 kilometers on foot to deliver supplies to the front line. Russian reconnaissance drones in that direction have dropped by two thirds. At Kinburn Spit, supplies of ammunition, food, and fuel have « effectively ceased » and Russian units have had to be evacuated.

These operational details matter. They show that Ukraine's strategy of targeting Russian logistical communication lines is producing concrete, measurable effects on Russia's capacity to maintain offensive pressure. A soldier walking 50 kilometers to carry ammunition is not fighting. A Pantsir destroyed in Crimea cannot defend Russian bases. A Nebo-U radar neutralized leaves blind spots in Russian air defense. The accumulation of these tactical degradations, even if each taken individually is not decisive, creates systemic pressure on Russian military capability.

Putin Reiterates Impossible Objectives While His Army Bleeds

The rhetoric of Ukraine's complete capitulation

While his army absorbs massive casualties at Kostyantynivka, while his refineries burn, while Crimea runs short of fuel, Vladimir Putin reiterates his commitment to achieving Russia's « original war objectives » — the complete capitulation of Ukraine. Sergei Lavrov maintains an evacuation order for foreign embassies in Kyiv and threatens Russian strikes of « large scale ». That language is the language of imminent victory. It is not corroborated by battlefield reality.

This dissonance between discourse and reality serves a function: maintaining the cohesion of the Russian population and elites around a narrative of victorious war. Russian propaganda is designed for a domestic audience, not for foreign analysts. But that function itself reveals the Kremlin's vulnerability: it needs to lie because the truth is unacceptable. A regime confident in its victory does not need to permanently maintain an « evacuation order » for the embassies of a city it claims to be on the verge of « liberating ».

Russia's demographic problem: documented personnel shortages since 2022

One of Russia's structural challenges in this war is demographic. Personnel shortages are described by the ISW as « systemic since May 2022 ». In an effort to fill those gaps, the Kremlin is multiplying recruitment bonuses: the governor of Leningrad Oblast announced a one-time payment of 250,000 rubles (3,356 dollars) for recruits joining mobile fire-support groups, and a bonus of 100,000 rubles (1,342 dollars) for each Ukrainian drone intercepted. Those figures reveal both the desperation of Russian recruitment and the value Moscow places on neutralizing Ukrainian drone capabilities.

Russia is also exploring the use of Belarus as a potential recruitment base. The Kremlin may attempt to use the Belarusian population to compensate for its labor shortages, according to the ISW. Belarus is described as « co-belligerent » in this conflict — its territory serves as a sanctuary for Russian strikes and a logistics base — but its own citizens have not yet been massively integrated into the Russian war effort. If that step is taken, it will represent a significant escalation in the nature of the conflict.

European Funding and Arms Deliveries: Ukraine Better Supported in 2026

European commitments that change the military equation

In 2026, Ukraine benefits from an unprecedented level of Western financial and military support since the war began. The Netherlands signed a cooperation memorandum including 250 million euros for Ukrainian drone production. The United Kingdom plans to provide more than 150,000 drones manufactured in Ukraine by year's end. Countries like Poland, whose defense budget now exceeds 4% of GDP, are providing equipment and logistical support. The architecture of Western support to Ukraine has considerably strengthened since the beginning of Trump's second term — perhaps precisely because Europeans can no longer count on Washington as an exclusive lever.

Ukraine has also strengthened its own domestic production capabilities for ammunition and weapons systems. The doctrine of « urgent war economy » — rapid iteration, flexible standards, real-time integration of combat feedback — has produced results that conventional armies struggle to match in speed. Ukrainian ballistic missiles are in advanced development. AI-guided interceptors are beginning to be deployed. Ukraine in summer 2026 is militarily stronger than it was in summer 2025. That asymmetric progression is key to any assessment of Russian sustainability.

JDAM-ER deliveries and precision strikes

On June 23, 2026, a Ukrainian strike with a guided JDAM-ER — an American precision-guided bomb adapted for Ukrainian aircraft — targeted a concentration of Russian personnel south of Udachne. That same day, a Russian drone training center « Dzerzhinsk » of the 4th motorized brigade was struck near Debaltseve. These precision strikes on high-value military targets deep in the Russian order of battle illustrate a Ukrainian capability that has considerably developed: striking precisely, far from the line of contact, targets that disrupt Russian operations.

This capacity for deep and precise strikes is one of the most significant developments of the war in summer 2026. It forces Russia to disperse its equipment and training forces far from the line of contact, which complicates coordination and lengthens logistics delays. It creates permanent pressure on the entire Russian strategic depth — from Moscow's oil infrastructure to the Donbas training centers. Ukraine does not have the means to launch a massive ground offensive. It has the means to make any Russian offensive unsustainable over the long term.

Ukrainian Counter-Offensives and Crimea as a Decisive Theater

The strategy of isolating Crimea

Ukraine's strategy in summer 2026 appears to revolve around a central axis: isolating Crimea from continental Russian logistics. The railway bridge over the North Crimea Canal was destroyed. Railway repair equipment deployed to rebuild it was struck in turn. Russian supplies toward the front line at Hulyaipole from Crimea have been « significantly reduced ». Strikes on fuel infrastructure at Kerch have caused power outages in several districts. If this strategy succeeds in cutting Crimea from continental logistics flows, Russian forces stationed in the peninsula will face growing supply challenges.

Crimea is symbolically and militarily central in Putin's calculations. By annexing it in 2014, he tied his own political fate to possession of that territory. If Ukraine can make Crimea untenable — not necessarily through a ground reconquest, but through a continuous degradation of its logistical viability — the psychological and political impact on the Russian regime will be considerable.

Russian USVs and the emerging naval war

On the night of June 22 to 23, 2026, Russian forces attempted to attack the Ukrainian coast with several unmanned surface vehicles (USVs) equipped with Starlink systems. They were detected and destroyed at sea by Ukrainian forces. That initiative reveals two opposing realities: on one hand, Russia is also developing autonomous maritime capabilities; on the other, Ukraine maintains operational superiority in the Black Sea that allows it to neutralize those attempts. Unmanned naval warfare is an emerging dimension of this conflict whose implications analysts are only beginning to measure.

The Black Sea has become an operational theater where Ukraine, despite the absence of a significant surface navy, has managed to reclaim shipping lanes and force the Russian Black Sea Fleet's withdrawal from its main Crimean bases. That is a considerable strategic success, achieved primarily through USVs and naval drones, which illustrates Ukrainian capacity to compensate for capability asymmetries through doctrinal and technological innovation.

Strikes on Crimea as the War's Decisive Theater

Why Crimea is the key to the conflict

On the night of June 22 to 23, 2026, Ukraine struck simultaneously more than 60 targets in Crimea, according to the ISW. Those strikes targeted critical Russian military infrastructure: fuel depots, air defense systems, port facilities at Sevastopol. That level of operation is not a demonstration — it is the application of a clear strategic doctrine: make Crimea defensively untenable for Russia. The logic is simple but powerful: if Russia cannot use Crimea as a secure rear base, its military positioning in southern Ukraine becomes structurally vulnerable.

Crimea is the logistical center of gravity of the Russian southern theater. It is from there that ammunition, fuel, and materiel flow to Russian forces deployed in the oblasts of Kherson and Zaporizhzhia. It is there that the Black Sea Fleet — or what remains of it after successive Ukrainian strikes since 2022 — finds its home ports. Every Ukrainian strike on Crimea is therefore an attack on the Russian supply chain, not only on the geopolitical symbol the peninsula represents.

The Black Sea Fleet: from regional power to refuge fleet

The Russian Black Sea Fleet is one of the most documented casualties of the conflict. Since 2022, Ukraine has sunk or severely damaged several major Russian warships, including the Moskva (flagship cruiser, sunk April 2022), several submarines, and landing ships. In June 2026, the fleet operates largely from ports out of range of Ukrainian drones — Novorossiysk and installations further east. Russian naval dominance in the Black Sea, which seemed assured in 2022, has eroded to the point that Ukraine can today export its grain by sea without Russian permission.

That transformation of the naval dynamic in the Black Sea is one of Ukraine's least-commented strategic successes. It was accomplished without a significant surface navy, using innovative maritime drones manufactured in Ukraine (notably the naval drone Magura V5), ally-supplied anti-ship missiles, and terrain knowledge acquired over decades. It is another illustration of Ukrainian capacity to compensate for capability asymmetries through doctrinal and technological innovation.

The Loss Ratio at Kostyantynivka: What the Numbers Say

53 Russian casualties to 3 Ukrainian: a ratio Russia refuses to publish

One of the most revealing indicators of the state of the war in summer 2026 is the loss ratio documented by the ISW around Kostyantynivka. On that stretch of the front in the Donetsk region, Russian casualties amounted according to the ISW assessment of June 23, 2026 to approximately 53 Russian casualties per day, against only 3 Ukrainian casualties. That is a ratio of 18 to 1 — a loss asymmetry that, if sustained over time, is strategically unsustainable for Russia. Source note: these ISW estimates are based on open-source intelligence, not verified official counts.

Rigor is required with these figures. The ISW data are estimates based on open-source intelligence, testimonies, and satellite imagery — not verified official counts. Both parties have an interest in minimizing their own casualties and exaggerating the adversary's. The real ratio could be different. What this figure indicates with reasonable certainty is a trend: Russian forces are suffering proportionally far higher casualties on certain front sectors, due to costly infantry assault tactics against well-fortified Ukrainian defensive positions. That trend is consistent with other independent sources.

Accumulated Russian casualties: a demographic time bomb

Russian human losses since February 24, 2022 are estimated, according to various Western sources, at several hundred thousand soldiers killed or seriously wounded. Those figures cannot be independently verified — neither Russia nor Ukraine publishes complete data. But several indicators confirm the scale of the problem: repeated increases in Russian enlistment bonuses, recruitment drives in the poorest regions, systematic reliance on convicts, and testimonies from Russian families in remote regions. Russia is bleeding humanly — and Putin compensates with quantity rather than quality.

That strategy of raw human attrition has a demographic limit. Russia has a population of 144 million, with a shrinking proportion of men of fighting age. The exodus of men fleeing mobilization in 2022 is documented in several studies. And current casualties are not offset by the birth rate. Over a war of several years, the demographic constraint becomes as strategic as the material constraint.

European and American Funding: Ukraine Better Supported in 2026 Than in 2024

European aid: record levels in 2026

A major structural change in the conflict equation in 2026: European funding for Ukraine has for the first time exceeded American funding in absolute terms. The European Union and its members, collectively, have committed record amounts of military and financial aid to Ukraine for 2026. The United Kingdom has maintained its high level of commitment. Poland, which shares a border with Ukraine, remains one of the largest contributors in proportion to its GDP. Meanwhile, American aid has been conditioned by Congressional debates and the ambiguities of Trump's policy.

This Europeanization of support for Ukraine is an important strategic development. It reduces Ukrainian dependence on the unpredictable political decisions of Washington — a real vulnerability since Trump's election. It also reinforces the resilience of the defense effort: if Washington were to reduce its aid, Ukraine would not be stripped of resources overnight. That diversification of support sources is one of the positive outcomes of the conflict's persistence — ironically.

Weapons deliveries in 2026: long-range systems and massive munitions

Weapons deliveries to Ukraine in 2026 reflect a qualitative evolution. In 2022–2023, allies primarily provided artillery, armored vehicles, and air defense systems. In 2026, deliveries include long-range missiles (British and French Storm Shadow/SCALP, American ATACMS), guided munitions in large quantities, and support for Ukraine's own defense industry — not only equipment, but production technology. Ukraine is thus transitioning from military client to defense industrial partner.

That transformation of the aid model is strategically significant. Giving equipment creates logistical dependence. Helping build a defense industry creates lasting autonomy. If Ukraine can produce its own drones, its own munitions, and some of its own weapons systems, it is less vulnerable to the political fluctuations of its allies. Ukrainian defense industrial policy aims precisely at that autonomization — and it is advancing, as the smoke from Kapotnya demonstrated.

Conclusion: Russia Is Bleeding — and Refuses to Say So

A Russian strategy that exhausts without winning

In summer 2026, Russia's strategy is one of exhaustion: advance slowly, accept massive casualties, hope that Ukrainian war fatigue and Western support run dry before Russia collapses. That strategy has a logic — it came close to working several times since 2022. But in 2026, with European support strengthening, Ukrainian production capabilities ramping up, and deep strikes degrading Russian economic and logistical infrastructure, the equation is increasingly unfavorable to Moscow. The 18:1 loss ratio at Kostyantynivka is not indefinitely sustainable.

What Ukraine must do to convert this attrition into victory

Ukraine will not win this war through a great ground offensive. It will win — if it wins — through the accumulation of unsustainable pressures on Russia's capacity to sustain the war: persistent human losses, degraded economic infrastructure, disrupted logistics, the financial cost of the war increasingly difficult to bear in the face of sanctions. That is a long-term strategy, not a spectacular one, but mathematically sound if Western support remains stable. That « if » remains the critical variable in the equation.

My sources and my posture

I am Maxime Marquette. This report draws primarily on the ISW assessment of June 23, 2026, a recognized and rigorous source whose casualty figures and operational assessments remain estimates based on open sources. I am pro-Ukrainian — that position shapes my reading of events.

What I cannot verify

Russian and Ukrainian casualty figures cannot be independently verified. Both sides communicate strategically. ISW estimates are the best publicly available data, but they carry significant margins of uncertainty. I also note that the Ukrainian military production figures I cite come from official statements and industry sources, not independent verification.
