Russian forces captured 4,831 square kilometers of Ukrainian territory in 2025, according to the Institute for the Study of War (ISW). This represents 0.8% of Ukraine's total land area. The average daily rate of advance across the entire theater was 13.24 square kilometers per day, the ISW reported. The highest rate of advance occurred in November, at 20.99 sq km per day, while the slowest month was October, with 8.8 sq km per day. These figures indicate a significant acceleration in Russian territorial gains compared to earlier periods of the war.
In the Pokrovsk sector, Russian forces advanced an average of 0.12 kilometers per day from July 31 to November 26, according to the ISW. As of November 26, Russian forces had consolidated advances in only 66 percent of Pokrovsk. At a constant rate of advance, Russian forces could seize the remainder of Ukrainian-held Donetsk Oblast by August 2027, the ISW projected. This projection underscores the slow but steady progress in a key frontline area.
Russia's drone production capacity has also ramped up significantly. By the end of May 2025, Russia produced around 2,700 Shahed drones per month, according to vgi.com.ua. Additionally, Russia produced about 2,500 decoy drones per month by the same date, the outlet reported. These decoys are likely used to overwhelm Ukrainian air defenses and complicate targeting.
The Shahed drones themselves have undergone upgrades. According to multiple reports, Russian attack drones, still commonly called Shahed, have upgraded engines compared to 2022. The upgraded drones fly higher and faster than before, making them harder to intercept. However, the sound of the drones is still characteristic and cannot be mistaken for anything else, according to reports. This distinctive noise remains a key identifier for Ukrainian forces.
Russian forces have also begun using fiber-optic drones with an increased range, according to the ISW. The range was extended from 7 kilometers to 20 kilometers by summer 2025. These drones are resistant to electronic warfare, as fiber-optic cables are not susceptible to jamming. The extended range allows them to strike deeper into Ukrainian-held territory.
Across the entire theater, Russian forces advanced an average of 9.3 square kilometers per day between August 15 and November 20, according to the ISW. This figure is lower than the full-year average of 13.24 sq km per day, suggesting that the pace of advance accelerated later in the year. The discrepancy may reflect different time periods or methodologies, but the later data points to a trend of increasing territorial gains. The exact number of Shahed drones Russia currently produces per month remains unknown, as does the precise number of decoy drones. The current range of Russian fiber-optic drones is also not publicly confirmed. Additionally, the total area of Ukrainian territory captured by Russia since the start of the full-scale invasion has not been officially disclosed. The specific technical specifications of the upgraded Shahed drone engines are also unclear.
