In July 2026, Russia introduced a formidable new weapon during its strikes on Kyiv — the Geran-4 jet drone, capable of reaching speeds of 500 kilometers per hour and engineered to bypass current air defense systems, including US-provided Patriot missile batteries. This drone played a pivotal role in the deadliest attack on Kyiv in 2026, resulting in the deaths of 30 individuals on July 2. Analysts from ISW assert that the Geran-4 signifies a significant advancement in drone warfare, operating too swiftly for conventional interceptors and flying at altitudes that evade radar detection. Military experts caution that should Russia share Geran-4 technology with Iran, which has previously benefitted from Russian drone assistance, American forces in the Persian Gulf may encounter a threat for which no existing US Navy defense system is adequately equipped.
