Ukraine Deploys FP-5 'Flamingo' Cruise Missiles — Strikes Shahed/Iskander Electronics Factory 1,200 km Inside Russia

On May 5, 2026, Ukraine announced its first confirmed combat use of the domestically developed FP-5 'Flamingo' cruise missile, striking the JSC VNIIR-Progress defense electronics manufacturing plant in Cheboksary, Chuvash Republic, more than 1,200 km (750 miles) from the Ukrainian border. The VNIIR-Progress plant is a key node in Russia's weapons production network: it manufactures electronic warfare and guidance components for Shahed-type loitering munitions, Iskander-K cruise missiles, and guided aerial bomb modules (KABs). Zelensky confirmed the strike, releasing video footage of the facility ablaze. Satellite imagery independently confirmed fires at the plant. The attack demonstrated Ukraine's significantly extended deep-strike capability using domestically produced missiles — a major escalation of Ukraine's strategic campaign against Russian military-industrial capacity. Russia's Chuvash Republic authorities reported 2 people killed and several wounded in the broader Chuvashia attack package, which also included a 289-drone wave launched simultaneously. The Flamingo strike follows a long pattern of Ukrainian deep strikes targeting Russian infrastructure in 2026, including the Tuapse refinery campaign and the Kirishi refinery attack on the same day.
