On August 15, Russian Defense Minister Andrey Belousov inspected the Eastern Grouping of Forces, and the Russian Ministry of Defense announced that its forces captured Rybalske and 19 other settlements in the Oleksandrivka and Hulyaipole directions as part of a summer campaign. The announcement follows a pattern in which Russian military officials and affiliated milbloggers claim extensive gains, a narrative that the Institute for the Study of War (ISW) says is not fully supported by independent evidence. Milblogger Voin DV released video on August 14‑15 showing Russian soldiers in a series of villages across Dnipropetrovsk, Donetsk and Zaporizhia oblasts, claiming the footage was recorded between August 12 and 14; the ISW noted that some of the video may be AI‑generated or altered and does not confirm actual territorial control. Ukrainian forces conducted a counteroffensive in the Oleksandrivka direction in early August 2026, employing combined‑arms tactics, drone support and mechanized maneuver; Ukrainian brigade spokespeople reported that their units, with drone assistance, overcame Russian resistance and fully seized 19 of the 26 previously Russian‑occupied settlements, while also liberating the village of Filiya. Ukrainian forces struck the Progress Space Rocket Center in Samara City overnight on August 14‑15 with FP‑5 Flamingo cruise missiles, causing a fire; Fire Point confirmed the missile impact, and geolocated imagery showed smoke rising from the facility, which produces Soyuz‑type launch vehicles. The Ukrainian General Staff reported that Ukrainian missiles hit Savasleyka Air Base in Nizhny Novgorod Oblast, igniting a fire; the base houses MiG‑31K fighters used for Kinzhal missile launches, and Ukrainian sources posted footage of the blaze. Russian forces launched 152 long‑range strike drones, including Shahed and Gerbera models, overnight on August 14‑15; the Ukrainian Air Force said it intercepted 124 drones and three loitering munitions, while debris from the remaining attacks hit a single location. Russia has begun equipping its intermediate‑range strike drones with jet engines, such as the Geran‑4 and Geran‑5 variants, to increase speed and evade Ukrainian air defenses; the Russian Aerospace Forces have deployed several A‑50U airborne early warning aircraft to assist in intercepting Ukrainian cruise missiles. Limited Russian offensive activity was reported in northern Sumy Oblast and northern Kharkiv Oblast, with no confirmed territorial gains; in the eastern Donetsk region, Ukrainian strikes hit a drone depot in Vuhledar and a control point in Selydove, while Russian forces continued to rely on glide bombs and drone attacks to disrupt Ukrainian logistics. Ukrainian cyber operations disrupted Wildberries’ customer service and payment systems on August 10‑11, and Ukrainian strikes on the Sheshkaris oil terminal in Novorossiysk led Russian authorities to suspend crude oil exports and impose cargo loading restrictions at the terminal. Neither side reported major changes to frontline positions on August 15, and the assessment indicates that Russian claims of extensive advances remain unverified while Ukrainian operations continue to target Russian logistics and air assets.
