Ukraine strikes Russian military plant 900km inside Russia with domestically-produced Flamingo missiles

Ukraine struck a Russian military factory over 900km from the front line using domestically-produced FP-5 Flamingo missiles. The VNIIR-Progress plant in Cheboksary, which produces critical anti-jamming antennas for Russian drones and missiles, was hit. The long-range attack is part of Kyiv's strategy to raise the costs of war for the Kremlin by targeting key military and energy infrastructure deep inside Russia.
