• Aeroflot CEO warns of SSJ-100 fleet loss without state engine subsidies.
• Replacing foreign-made engines with domestic ones is not feasible without government support.
• Russian airlines face a gradual phase-out of the SSJ-100 fleet.
• The cost of replacing engines is estimated at 2.1 to 2.3 billion rubles per aircraft.

This development may indicate significant challenges for Russia's commercial aviation sector under Western sanctions. The inability to replace foreign-made engines suggests a potential decline in the country's air transport capabilities, which could have broader implications for the economy and national security.
