On 23 July 2026 a Russian Su‑57 fifth‑generation fighter crashed during a training sortie in the Moscow region. Russian officials described the incident as a technical malfunction, noted the pilot’s safe ejection and reported no ground casualties while opening an investigation.

Ukrainian open‑source intelligence group InformNapalm later claimed the crash was caused by a Ukrainian cyber‑intelligence operation that penetrated Russia’s integrated air‑defence network, hijacked the BARS anti‑drone system and redirected a surface‑to‑air missile onto the Su‑57, resulting in the first known combat‑jet loss from a cyber‑enabled friendly‑fire event. British defence analyst Hamish de Bretton‑Gordon warned the loss could be a strategic “Waterloo” for President Vladimir Putin, given the aircraft’s $45 million unit cost and the limited size of Russia’s Su‑57 fleet.
