Aeroflot has ordered 90 additional MC-21-310 narrow-body aircraft from Yakovlev, the commercial aircraft unit of United Aircraft Corporation (UAC), bringing the flag carrier's total commitment to the type to 108 airframes.

The order consolidates Aeroflot's position as the anchor customer for the MC-21 program at a moment when the aircraft's commercial logic has been rewritten by sanctions rather than by market competition. The -310 designation matters here: it identifies the fully Russian-built variant of the MC-21, a re-engineering forced by circumstance rather than choice.

The MC-21 was originally certified with Western components. Those parts became unavailable after the United States and the European Union imposed economic sanctions following Russia's invasion of Ukraine, forcing UAC and its Yakovlev unit to replace foreign systems — including major structural and systems content — with domestically developed equivalents. The -310 standard is the result of that substitution effort.

For Aeroflot, the expanded order locks in the airline's fleet renewal path around a single domestic supplier. With 108 MC-21-310s now on order, the carrier has effectively tied its narrow-body replacement strategy to the production ramp that UAC can actually deliver — a metric that remains the central question mark over the program.

The commercial context is unforgiving. Sanctions have cut Russian carriers off from Airbus and Boeing deliveries, spare parts pools and lessor inventories, making domestic output the only route to net fleet growth. Aeroflot's order book with Yakovlev is therefore less a conventional fleet decision than a structural consequence of the sanctions regime: the airline needs the aircraft, and Russia's aviation industry needs a customer of scale to justify production investment.

The 108-aircraft figure gives the program a volume baseline that few other post-sanctions Russian types can claim. Whether UAC can convert that backlog into deliveries at a rate that meaningfully renews Aeroflot's fleet is the operational test ahead. Certification of the fully Russified variant cleared the regulatory hurdle; series production output is the constraint that will determine when the order turns into capacity on the carrier's network.

For now, the numbers stand as follows: 90 additional airframes ordered, 108 in total for Aeroflot, and a single certified fully domestic variant — the MC-21-310 — carrying the weight of Russian commercial aviation's narrow-body ambitions. Delivery schedules against that backlog will be the figure to watch.
