On July 6, 2025, Russia and Ukraine engaged in extensive drone strikes against each other, involving hundreds of drones and causing disruptions to Russian air travel. These attacks followed Ukrainian President Volodymyr Zelenskyy's announcement of agreements with Western partners aimed at increasing Kyiv's drone production capacity. Later in the month, on July 16, Russia launched large-scale drone and missile attacks across Ukrainian cities, including areas near President Zelenskyy's hometown. This escalation occurred shortly after former U.S. President Donald Trump issued a 50-day ultimatum for Russia to agree to a peace deal, warning of stiff tariffs if the ultimatum was not met. Russia has been rapidly expanding its drone production by increasing factory capacity and recruiting additional labor. The widespread use of mass-produced drones has become a key element in Ukraine's defense strategy, contributing to what has been described as the most militarily significant attack on Russia since World War II.
