Russia fired an Oreshnik hypersonic ballistic missile near Kyiv during a massive aerial assault overnight on Sunday, May 23, 2026 [1, 5].

The use of the Oreshnik weapon marks a significant escalation in the conflict, introducing a high-speed delivery system that is difficult for traditional air defenses to intercept.

The strike was part of a broader wave of attacks that targeted multiple Ukrainian regions. According to report data, the Russian military launched approximately 600 drones [1] and approximately 90 missiles [1] in the operation. The assault continued into early Monday, May 24, 2026 [1, 5].

In Kyiv, the impact of the strike resulted in at least two deaths [3]. The Oreshnik missile is capable of traveling up to 10 times the speed of sound [4] — a velocity that allows it to penetrate deep into defended airspace.

Ukrainian President Volodymyr Zelenskyy said the deployment of such weaponry increases the risk of further escalation. Ukrainian officials have called for international consequences following the attack.

While some initial reports suggested Russia was only preparing to use the Oreshnik system, subsequent accounts confirmed the missile was fired near the capital during the overnight barrage [1, 6]. The Russian military aimed to intensify pressure on Ukraine by utilizing the new hypersonic capability [1, 6].

Kyiv continues to call for increased air defense support to counter the volume of drone and missile strikes that have characterized the recent phase of the war.

The deployment of the Oreshnik missile represents a shift in Russia's tactical approach, moving from conventional cruise and ballistic missiles to hypersonic technology. Because these weapons travel at extreme speeds, they significantly reduce the reaction time for Ukrainian and Western-supplied defense systems, potentially forcing Ukraine to relocate critical assets or change its defensive posture.
