The rate of Russian advances in Ukraine has been steadily declining since November 2024, in part due to successful Ukrainian counterattacks in eastern Ukraine. The UK Ministry of Defense (MoD) reported on April 5 that Russian forces advanced 143 square kilometers in Ukraine in March 2025 as Ukrainian forces conducted successful tactical counterattacks in the Pokrovsk direction.[1] The UK MoD reported that the rate of Russian advances in Ukraine has decreased each month since November 2024, as Russian forces seized roughly 730 square kilometers in November 2024, 393 square kilometers in December 2024, 326 square kilometers in January 2025, and 195 square kilometers in February 2025.[2]
ISW has observed geolocated footage to concur in the assessment that the monthly rate of Russian advances in Ukraine has decreased since November 2024.[3] ISW has observed geolocated evidence to assess that Russian forces in Ukraine gained roughly 627 square kilometers in November 2024, 569 square kilometers in December 2024, 427 square kilometers in January 2025, 354 square kilometers in February 2025, and 203 square kilometers in March 2025. The UK MoD likely uses a different methodology or sources to assess Russian advances in Ukraine, but the UK MoD's report is consistent with evidence ISW has observed of decreasing monthly Russian advances between November 2024 and March 2025. Ukrainian forces have conducted localized counterattacks in the Pokrovsk and Toretsk directions in recent weeks, regaining lost positions in these areas and contributing to slowing Russian advances in Ukraine.[4]
Russian forces conducted the largest series of missile and drone strikes against Ukraine in nearly a month on the night of April 5 and 6.[5] The Ukrainian Air Force reported that preliminary data states that Russian forces launched nine Kh-101/Kh-55SM cruise missiles from Tu-95MS aircraft from the airspace over Saratov Oblast; eight Kalibr cruise missiles from the Black Sea; six Iskander-M ballistic missiles from Bryansk Oblast; and 109 Shahed and decoy drones from the directions of Bryansk City; Millerovo, Rostov Oblast; Primorsko-Akhtarsk, Krasnodar Krai; and occupied Cape Chauda, Crimea.[6] The Ukrainian Air Force reported that Ukrainian forces downed six Kh-101/Kh-55SM cruise missiles, six Kalibr missiles, one Iskander-M ballistic missile, and 40 Shahed drones and that 53 decoy drones were "lost," likely due to Ukrainian electronic warfare (EW) interference. Ukrainian officials reported that Russian forces struck residential and civilian infrastructure in Kyiv, Sumy, Kharkiv, Kirovohrad, Khmelnytskyi, Cherkasy, and Mykolaiv oblasts and that five Iskander-M ballistic missiles struck Kyiv Oblast.[7]
Ukrainian Air Force Spokesperson Colonel Yuriy Ihnat reported on April 6 that Russian forces are changing their strike tactics and constantly modernizing their Shahed drones and ballistic missiles, complicating Ukrainian forces' ability to shoot them down.[8] Ihnat noted that the US Patriot air defense system is effective against ballistic missiles. Russian forces have repeatedly experimented with different strike packages in order to overwhelm Ukrainian air defenses and ensure that Russian missiles – particularly the ballistic missiles that are more difficult for Ukrainian air defenses to shoot down – are able to reach their intended targets.[9] Russian forces likely launched missiles and drones on the night of April 5 to 6 from various locations in the Black Sea, Russia, and occupied Crimea, as part of these experimentation efforts.
Ukrainian officials highlighted the fact that Russia is leveraging its naval...
