Territory Overview: The Numbers

Ukraine has a total internationally recognized territory of approximately 603,550 km² (including Crimea). As of early 2026, Russia occupies an estimated 110,000-120,000 km² — approximately 17-19% of this total. This is substantially less than Russian forces controlled at the maximum extent of the 2022 invasion (when forces approached Kyiv and controlled much of northern Ukraine temporarily) but more than the roughly 40,000-50,000 km² Russia controlled through proxies before February 2022.

The frontline itself — the active contact line between Ukrainian and Russian forces — runs approximately 1,000-1,100 kilometers from north of Kharkiv Oblast southward through Donetsk and Zaporizhzhia oblasts to the Dnipro River in Kherson Oblast. This is among the longest active frontlines in Europe since World War II. A secondary contact zone exists along the Dnipro River in Kherson Oblast, where Russian forces hold the left (east) bank and Ukrainian forces hold the right (west) bank.

The Russian-occupied territory encompasses some of Ukraine's most economically significant regions. Pre-war, the occupied territories contained significant portions of Ukraine's steel and industrial production (Donetsk Oblast), coal mining, agricultural land, Black Sea coastline, and the Zaporizhzhia Nuclear Power Plant — Europe's largest. The economic significance of occupied territory exceeds its geographic share of Ukraine's area.

Crimea

Crimea — the peninsula that Russia annexed in March 2014 — remains under Russian control as of early 2026 but has experienced significant military pressure that has substantially degraded Russian military capability there. Ukrainian strikes on the Crimean bridge (Kerch Bridge), Black Sea Fleet headquarters in Sevastopol, naval vessels, air defense systems, and logistics infrastructure have transformed Crimea from an impregnable Russian base into a vulnerable logistical liability requiring extensive air defense investment.

The Black Sea Fleet withdrawal from Sevastopol to Novorossiysk — driven by Ukrainian naval drone and missile strikes — was one of the most symbolically significant territorial-strategic developments of the war. Russia no longer operates its flagship naval forces from Crimea itself, representing a major operational degradation of what was the original strategic prize of the 2014 annexation. Crimea's value as a forward military base has been substantially diminished even as Russia retains physical control.

Crimea's population of approximately 1.9 million includes a significant Russian and Russian-speaking majority (reinforced by Russian population transfers since 2014) and a Crimean Tatar minority that has been subject to documented repression under Russian occupation. The political question of Crimea — not a new dispute created by the 2022 invasion but an unresolved issue since 2014 — remains one of the most difficult in any peace scenario.

Donbas: Luhansk and Donetsk

The Donbas region — comprising Luhansk and Donetsk oblasts — is where the war's fighting is most intensive. Russia controls nearly all of Luhansk Oblast (approximately 97-98%), having captured Sievierodonetsk and Lysychansk in summer 2022. In Donetsk Oblast, Russia controls approximately 55-60% of the oblast area, including Donetsk city (the oblast's pre-war capital, nominally under Russian-backed separatist administration since 2014), Mariupol (captured April 2022), Bakhmut (captured May 2023), Avdiivka (captured February 2024), and surrounding territory.

Active fighting in Donetsk Oblast continues primarily in the western Donetsk arc — the areas around Chasiv Yar, Toretsk, Kurakhove, and the approaches to Pokrovsk. Russian forces have been pressing westward from the captured Avdiivka salient toward Pokrovsk, which serves as a critical Ukrainian logistics hub for the entire Donetsk sector. Pokrovsk's potential capture would have significant operational implications for Ukraine's ability to sustain defensive operations across the Donetsk axis.

The Donetsk frontline represents the most attritionally intense fighting of the war through 2024-2025. Russian advances, while measured in kilometers or even hundreds of meters per week in many sectors, have been consistent and continuous. Ukraine has contested every meter using defensive depth and drone-enabled fires, but the asymmetry of Russian manpower and artillery ammunition advantage in this period has produced a slow westward drift of the contact line.

Zaporizhzhia Oblast Frontline

Zaporizhzhia Oblast presents one of the most strategically significant and contested frontline sectors. Russia controls approximately 60-65% of the oblast area, including Melitopol (a critical logistics hub and transportation node), the Zaporizhzhia Nuclear Power Plant (ZNPP — Europe's largest nuclear facility), and the land corridor connecting Crimea with occupied Donetsk and Luhansk. This land corridor through Zaporizhzhia and Kherson oblasts along the Sea of Azov coast was one of Russia's primary revealed war objectives — connecting Crimea to Russia's Rostov region through controlled overland territory.

Ukraine's 2023 counteroffensive was most ambitious in Zaporizhzhia Oblast — attempting to drive south from Orikhiv toward Tokmak and Melitopol, potentially severing the land corridor. The counteroffensive achieved limited gains — the most notable at Robotyne, roughly 10 kilometers south of Orikhiv — against Russian defensive lines that had been prepared in depth over many months. Russia's layered minefields, anti-tank obstacles, and fortified defensive positions halted the Ukrainian advance well short of the strategic objectives.

Since the counteroffensive's end in late 2023, Russian forces have been probing and pressing in Zaporizhzhia Oblast, seeking to recover the limited gains Ukraine made. Ukraine retains Orikhiv and the Robotyne area but has been under pressure to defend what was gained at enormous cost. The ZNPP's situation — with its safety systems under strain from the war's effects on power supply and personnel — remains a persistent international concern.

Kherson Oblast: The Liberated and the Occupied

Kherson Oblast is divided by the Dnipro River into Ukrainian-held right bank and Russian-held left bank. Ukraine's November 2022 liberation of the right bank — including Kherson city — was the war's most significant Ukrainian territorial recovery and a major strategic and symbolic success. Russian forces withdrew across the Dnipro and have been on the left bank since, with Ukrainian forces unable to execute a major river crossing against prepared Russian defenses along the left bank.

The Dnipro River line in Kherson Oblast is not a static frontline but an active crossing zone where Ukrainian special operations forces have conducted repeated operations to establish and hold positions on the left (Russian-held) bank. Ukrainian bridgehead attempts around Krynky drew significant attention in 2023-2024 before being reduced under sustained Russian pressure. The Kherson direction represents opportunities for Ukrainian offensive pressure while also potentially reducing Russian ability to mass reserves for Donetsk operations.

Kherson city — on Ukraine's side of the Dnipro — is continuously targeted by Russian artillery from positions on the left bank. The city experiences near-daily shelling causing civilian casualties and infrastructure damage. The situation illustrates the unique challenge of Kherson: liberated but not safe, within direct artillery range of Russian positions, with the civilian population experiencing a sustained siege of indirect fire even under Ukrainian control.

Kharkiv Oblast: The Recovered North

Kharkiv Oblast was the site of Ukraine's most decisive counteroffensive success. September-October 2022 saw Ukrainian forces break through Russian defensive lines at multiple points in the oblast, recapturing approximately 8,000 km² including the towns of Balakliya, Izium, and Kupyansk in a rapid advance that forced Russian withdrawal from positions held since February-March 2022. The Kharkiv counteroffensive demonstrated that Ukrainian initiative and operational surprise could achieve major territorial recovery even against nominally prepared defensive positions.

May 2024 saw a Russian counterattack in northern Kharkiv Oblast — a cross-border incursion from Belgorod Oblast that captured several small villages near Vovchansk. Ukrainian forces contained the advance fairly quickly, with Russian gains limited to a relatively shallow belt south of the border. The Kharkiv incursion was widely analyzed as intended to force Ukraine to divert reserves from other sectors to defend Kharkiv approaches, potentially serving Russian operational interests on the main Donetsk axis rather than representing Russia's genuine ability to threaten Kharkiv city itself.

As of 2026, Ukrainian forces hold substantially all of Kharkiv Oblast outside the narrow Russian-held strip near the border. Kharkiv city — Ukraine's second-largest with approximately 1 million residents — is approximately 30-40 km from Russian territory and has experienced sustained missile and guided bomb attacks. The city's industrial capacity, university system, and population have been significantly disrupted by the war's proximity, but the city itself has not been militarily threatened with capture since the 2022 defense.

Frontline Changes 2022–2026

The war's territorial trajectory can be organized into five phases. Phase 1 (February-April 2022): Initial Russian invasion, maximum Russian territorial control, failed capture of Kyiv. Phase 2 (April-August 2022): Russian withdrawal from north, Russian capture of Mariupol and Luhansk Oblast. Phase 3 (September-November 2022): Ukrainian counteroffensives recapture Kharkiv Oblast and Kherson Oblast right bank — Ukraine's maximum territorial recovery. Phase 4 (December 2022-May 2023): Attritional fighting, Bakhmut battle, Russian capture of Bakhmut. Phase 5 (June 2023-present): Ukrainian counteroffensive limited gains, Russian capture of Avdiivka (February 2024), slow Russian advance in Donetsk.

The net territorial balance through three years shows Ukraine recaptured substantial territory in 2022 compared to the initial invasion peak but has since been under net pressure on the Donetsk axis. Russia holds substantially more territory than before February 2022 but substantially less than the maximum extent of initial invasion territory. The trend since late 2023 has been Russian slow advance, but at rates suggesting a war of years rather than months remaining.

Key Contested and Threatened Cities

The city most directly threatened by frontline proximity as of early 2026 is Pokrovsk in Donetsk Oblast. Russian forces have been advancing toward Pokrovsk from the east and southeast, closing the distance to under 10 kilometers at points. Pokrovsk is a major logistics hub — its loss would force Ukraine to reorganize supply routes across the Donetsk axis. Ukraine has been evacuating civilians and preparing defensive positions around the city, treating its defense as an operational priority.

Chasiv Yar — described in detail in the Chasiv Yar battle article — is directly contested as of early 2026, with Russian forces controlling portions of the city and Ukrainian forces defending the canal line and western areas. Kostiantynivka, Zaporozhye city (the Zaporizhzhia Oblast administrative capital remaining in Ukrainian hands, approximately 40 km behind the line), and Dnipro (further west but subject to air strikes) are additionally in categories of concern at varying levels of immediate threat.

Occupied Population and Humanitarian Situation

Russia's occupied territories contained approximately 10-12 million people before the full-scale invasion. By 2026, this population has been significantly reduced by displacement: hundreds of thousands fled to Ukrainian-controlled territory or abroad; others were forcibly transferred (deported) to Russian territory — a process documented by international bodies as potentially constituting a war crime. Russia has transferred Ukrainian children to Russia in documented numbers, leading to an International Criminal Court arrest warrant for Putin and Russian Children's Commissioner Maria Lvova-Belova.

The population remaining in occupied territory — estimated at 4-7 million depending on methodology and definition — lives under Russian military administration with documented human rights violations: forced passport issuance, required curriculum changes in schools, property confiscation, arrests of perceived resisters, and systematic Russification policies. The UN and human rights organizations have documented these conditions through monitoring including satellite imagery, witness testimony, and limited direct access.
