Russia's Baikal LMS-901 Flies with Domestic VK-800 Engine, Signaling New Era

The Baikal light-engine multipurpose aircraft has completed a major milestone. The LMS-901 "Baikal" performed its first flight using a fully domestically produced power plant. This test flight was powered by the Russian-made Klimov VK-800 engine. It also used the new Russian Aerosila AV-901 propeller. The Russian Industry and Trade Ministry confirmed the successful flight on December 24, 2025.

This flight took place at the airfield of the Ural Civil Aviation Plant (UZGA) near Yekaterinburg. During the test, the aircraft reached an altitude of 400 meters. It maintained a speed of 210 km/h. Test pilots reported that the aircraft was stable and well-controlled. They also assessed the engine’s stability and fuel supply.

A Critical Step for Domestic Aviation

This successful flight is a major win for Russian import substitution. The LMS-901 program was initially designed around the foreign General Electric H80-200 engine. Following international sanctions, the program shifted to the domestic VK-800 engine. This change was necessary to ensure the aircraft's long-term viability.

Development of the VK-800 turboprop engine is led by UZGA. The engine is a key component in Russia's regional aviation revival strategy. It is designed to produce 877 horsepower. This power is vital for operations on short, unpaved runways.

Replacing the Legendary An-2

The LMS-901 "Baikal" is designed to replace the Soviet-era Antonov An-2 "Corncob." The An-2 has been a workhorse for decades on local air routes. The nine-seat Baikal offers a modern, efficient alternative. Its design allows for passenger, cargo, and specialized roles.

The aircraft is planned to carry up to 9–12 passengers. It can also transport a maximum payload of 2,000 kg. Its cruising speed is targeted at 250–300 km/h. The flight range is expected to be up to 1,520 km.

Certification and Delivery Timeline

The flight marks the start of a critical testing phase. Certification of the VK-800 engine and AV-901 propeller is targeted for the first quarter of 2026. The type certificate for the entire Baikal aircraft is expected by the end of 2026.

Regional carriers are already preparing for its introduction. Aerokhimflot is expected to be the first recipient. This alliance of aviation operators has leasing agreements for 50 aircraft. Deliveries are currently anticipated between 2027 and 2031. Aurora Airlines also reportedly signed a lease agreement for 105 aircraft.

• The successful flight mitigates the risk of reliance on foreign components.
• It demonstrates progress in Russia's domestic aerospace technology development.
• The Baikal will improve connectivity for remote Russian communities.
• The project must still meet certification and production targets to ensure timely delivery.

This development is closely watched by the global commercial aviation news community. It represents a significant step toward self-sufficiency in the light aircraft segment. The program's success is crucial for Russia's ambitious plan to modernize its regional fleet.
