The project is still under development, delayed due to the 2022 Russian Invasion of Ukraine.
[citation needed] In the mid-1980s, the Omsk OKB started developing the TV-O-100, a light 650 hp engine designed specifically for the Mi-44.
The engine would increase the aircraft's take-off weight to 1,800 kilograms (4,000 lb) and allow a maximum speed of up to 260 kilometres per hour (160 mph).
Early users determined that two 400 hp power plants would be optimal.
The most acceptable option to meet the requirement was the TVlD-450 engine, which would make the aircraft more agile.
