## Consequences of the Russia-Ukraine war

After [Russia invaded Ukraine](/source/Russian_invasion_of_Ukraine) in February 2022, all Soyuz launches performed via Starsem were suspended indefinitely.[2] This is also evident by the lack of news releases on the Starsem website since then, with the last headline from February 15, 2022.
