According to unconfirmed reports, the target of the Ukrainian cruise missile attack on Oryol was the "Proton" plant. The Proton Plant specialises in the production of components for Russian Iskander-M ballistic missiles, S-71K "Kovyor" air-launched cruise missiles, and Pantsir-S1 surface-to-air missiles. It was previously struck by several Storm Shadow cruise missiles on October 23. Today's attack was carried out either by FP-5 "Flamingo" or Neptune cruise missiles.
