Ukraine replaced Defence Minister Mykhailo Fedorov on July 15 and Commander‑in‑Chief Oleksandr Syrskii on July 21, the first simultaneous top‑level defence reshuffle since the war began, as Russian casualties reached their highest monthly total of the year.
The Ministry of Defence reported 193,500 Russian personnel killed or wounded through July 24, an average of about 32,000 per month, while the Institute for the Study of War estimated Russia’s net territorial gain at 81.1 km² and daily losses of 1.6 km² in July.
President Volodymyr Zelenskyy said on July 20 that he was assessing adjustments to Ukraine’s defence strategy and priorities for production and supply. Syrskii, who established the Unmanned Systems Forces (SBS), wrote that the war strategy should not be reduced to drone operations, noting that Russian forces still possessed superior artillery, aviation and infantry capabilities. Fedorov, in his six‑month tenure, oversaw a rapid increase in drone purchases, spending payroll funds to accelerate orders.
SBS reported disabling 196 fuel tankers and destroying three‑quarters of the ferry capacity across the Kerch Strait since June 6, and striking 117 power substations in Crimea, resulting in widespread outages that led the government to allocate five billion rubles for compensation to affected households and employees. Ukrainian strikes also hit a Tupolev‑95 bomber at Engels airfield, a MiG‑29 at Khalino, multiple air defence radars and launchers, the Slavneft‑Yanos refinery in Yaroslavl, and four Wildberries warehouses used by Russian recruits.
Russia responded by increasing the use of ballistic missiles in nightly attacks on Ukrainian cities since June 26, a shift from its previous practice of reserving missiles for larger combined strikes. Ukrainian forces said they intercepted roughly 95 % of drones and 87 % of cruise missiles but fewer than half of the ballistic missiles.
The reforms and emphasis on unmanned systems appear to have slowed Russian advances, with Ukraine noting net territorial gains in May and continued disruption of Russian logistics and energy infrastructure.
