Ukrainian forces used Flamingo FP-5 cruise missiles to strike a Russian military factory in Cheboksary on June 10 [1].

The operation targets the production of drone antennas and electronic components, aiming to degrade Russia's ability to manufacture unmanned systems. By striking deep within Russian territory, Ukraine is expanding its long-range strike capabilities to disrupt the military supply chain.

President Volodymyr Zelenskyy confirmed the strike and said the target was a key military plant producing components for drones [1]. The use of the FP-5 Flamingo cruise missile marks a significant reach for Ukrainian-made weaponry [2].

According to Zelenskyy, these missiles traveled over 1,000 kilometers to reach the factory [2]. Other reports place the distance from the front lines at approximately 900 kilometers [3], while some estimates suggest it exceeds 620 miles [1].

"We have hit a key military plant in Cheboksary that produces components for drones," Zelenskyy said [1].

The strike occurred overnight on June 10 [1]. The facility in Cheboksary is specialized in the production of drone antennas, and other critical electronic components used in Russian weapons systems [2].

Following the operation, Zelenskyy inaugurated the Day of the Unmanned Systems Forces [3]. This designation highlights the growing role of drone warfare and long-range precision strikes in the conflict.

"These FP-5 Flamingo missiles travelled over 1,000 kilometres to strike a factory that makes drone antennas," Zelenskyy said [2].

"We have hit a key military plant in Cheboksary that produces components for drones."

The strike on Cheboksary demonstrates Ukraine's evolving capacity to produce and deploy indigenous long-range precision weapons. By targeting the electronic components and antennas necessary for drone operations, Ukraine is moving beyond tactical battlefield strikes to strategic industrial sabotage. This shift forces Russia to reconsider the safety of its interior defense plants and may compel a reallocation of air defense assets from the front lines to deep-rear industrial hubs.
