Ukraine has struck a facility where launch vehicles used for Russia’s new satellite system are produced, in the latest strikes behind enemy lines.

The strike used Ukraine’s domestically produced Flamingo missiles to hit the site in the southwestern Samara region, approximately 900 kilometers (560 miles) from the border, as well as Russia’s Savasleyka air base, some 700 kilometers (430 miles) from the front line.

Samara’s Progress Center operates under Russian space agency Roscosmos and is involved in developing rocket technology and electronics.

It produces Soyuz-2 launch vehicles, which are used to project Rassvet satellites, Russia’s version of Elon Musk’s low-orbit satellite internet system Starlink.

Ivan Noskov, head of the region’s capital, Samara, confirmed that air defence forces had repelled a “massive” missile attack, with “localised damage” to the city’s industrial sites. He also said that medical assistance has been provided to those injured in the attack, but did not give further details.
