The most powerfull production helicoper in the World the Mil Mil-26

Uzbekistan issued a set of 8 postage stamps on 3 January 2012 to mark 20 Years of Armed forces of the Republic of Uzbekistan. Featured was this Mil Mi-26 helicopter of which some 50 helicopters are in the service of the nation used in search and rescue, heavy lift transport and for the movement of personnel.

The Mi-26 was the first helicopter with a single, eight-blade main lift rotor. It is capable of flight in the event of power loss by one engine thanks to an engine load sharing system. The Mi-26 has a payload of up to 20 metric tons. Its unique main gearbox is relatively light at 3,639 kg (stamped Aluminium)  but can absorb 19,725 shaft horsepower (14,709 kW), which was accomplished using a non-planetary, split-torque design with quill shafts for torque equalization. As of 2016, the Mi-26 still holds the Fédération Aéronautique Internationale world record for the greatest mass lifted to 2,000 metres  – 56,768.8 kilograms on a flight in 1982.
