Together with General Electric, Safran co-produces the world's most sold jet engines for Boeing and Airbus medium-haul airliners through their CFM venture. The widely watched civil aftermarket, depressed during the COVID pandemic, rose 52.9% in dollar terms in the first quarter, contributing to an 18.8% increase in total propulsion revenues. Safran had been active in Russia where it supplies engines for the Superjet regional plane and Kamov helicopters, while also providing services for some 500 CFM-powered jetliners. It has suspended exports and services under European Union sanctions imposed after Russia's invasion of Ukraine. Its ArianeGroup rocket venture with Airbus has suspended using Soyouz launches. Safran also relies on Russia for 50% of its needs of titanium, used in engine parts and landing gear. It said its 2022 needs were covered and it was securing alternatives.
