Mil Mi-26

Updated: October 2026 – When a Mi-26 thunders over you, the scale shifts. A rotor disc almost as wide as the wingspan of an A320, below it a cargo hold about as long as a city bus, and on the hook possibly another helicopter: the Mil Mi-26, NATO reporting name “Halo”, is the largest helicopter ever to go into series production. On this page you learn how it came about, what technology is inside it, which spectacular missions made it famous and how you recognize it at a glance – if you ever run into one.

What is the Mil Mi-26?

The Mi-26 is a heavy transport helicopter from the Moscow design bureau Mil, which also produced the all-rounder Mi-8/Mi-17 and the attack helicopter Mi-24 Hind. It transports vehicles, construction machinery, containers, drilling equipment and entire helicopters – to places with neither roads nor runways. Militarily it brings troops and heavy equipment to the front; in civil use it lifts power pylons, bridge sections or equipment for oil and gas projects.

Its importance follows from the geography of the Soviet Union: Siberia, the Far East and the high north are huge, sparsely populated and barely developed. A helicopter that brings a truck’s load to its destination without a road was no toy there but infrastructure. That is why the Mi-26 was to replace the older heavy-lift helicopter Mi-6 – with considerably more payload at hardly larger dimensions.

Development: from the Mi-6 to the Mi-26

In the early 1970s the Soviet leadership set the requirements: the new helicopter was to carry considerably more than the Mi-6 but not grow much larger and heavier. That forced the engineers into a new approach to rotor, gearbox and materials. Instead of a huge five-blade rotor as on the Mi-6 (around 35 meters in diameter), the Mil bureau went for a somewhat smaller rotor with eight blades that distributes the lift over more area. The main gearbox had to combine the power of two very powerful turbines – a task the bureau finally took on itself because no external developer could be found for it.

The first prototype took off on December 14, 1977. The first production aircraft was built in 1980 at the plant in Rostov-on-Don, today’s Rostvertol company, where the type is built and modernized to this day. The Mi-26 entered service with the Soviet armed forces in the mid-1980s; in parallel the civil version Mi-26T started, among others for Aeroflot. By the mid-2010s, a good 300 examples had been built.

The helicopter demonstrated its strength publicly early on: on February 3, 1982, a Mi-26 lifted a total mass of around 56.8 tonnes to 2,000 meters altitude on a record flight – a value that counts as an FAI world record.

Technology in brief

The heart is two Lotarev D-136 turboshafts sitting side by side on top of the fuselage in front of the rotor mast. For output, depending on source and version, values between around 10,000 and 11,400 hp per engine circulate – in any case in a class of their own in helicopter construction.

The main rotor measures 32 meters in diameter and carries eight blades on a titanium hub. At the rear on the raised tail boom sits a five-blade tail rotor of composite material that balances the torque. With rotors turning, the Mi-26 comes to about 40 meters overall length; the fuselage alone measures just under 34 meters.

The cargo hold is around 12 meters long, 3.2 meters wide and just under 3 meters high – roughly the dimensions of a truck bed, only taller. Loading is via two large rear doors that swing open to the sides and a lowerable ramp; two electric winches pull heavy, non-self-propelled goods into the hold. Optionally the load hangs from the external load hook under the fuselage. The maximum payload is 20 tonnes, the maximum takeoff weight 56 tonnes.

The landing gear is a fixed nosewheel gear. Cruise speed is around 255 km/h, top speed around 295 km/h. The classic crew consists of five people: two pilots, navigator, flight engineer and flight mechanic.

Feature	Mil Mi-26	Boeing CH-47F Chinook
ICAO type designator	MI26	H47
Rotor concept	1 main rotor (8 blades) + tail rotor	2 tandem rotors (3 blades each)
Rotor diameter	32.0 m	2 × 18.3 m
Max. takeoff weight	56 t	around 24.5 t (Block II)
Max. payload	20 t	significantly less
Rear ramp	yes, with double doors	yes

The comparison shows why the Mi-26 is unique: fully loaded it weighs more than twice as much as the CH-47 Chinook, which counts as the heavy-lift helicopter in the West. The Sikorsky CH-53, for a long time the Bundeswehr’s workhorse, plays in a smaller league as well.

Versions at a glance

Numerous variants appeared over the decades. For spotters they are mostly hard to tell apart from the outside; the identification or registration is decisive.

In addition there are special versions such as the flying cranes Mi-26TM and Mi-26PK with an extra cabin for a load operator, the medical version Mi-26MS and the tanker Mi-26TZ, which can dispense fuel to vehicles and other aircraft on the ground. Other projects such as the flying command post Mi-27 never got beyond two built examples.

Missions that made history

Hardly any helicopter has carried so many unusual loads. Some missions have become known even outside the aviation scene.

Chernobyl 1986: After the reactor disaster, Mi-26s flew over the stricken power plant. They measured radiation and dropped material meant to cover the open reactor. At least one specially adapted aircraft was so heavily contaminated afterward that it never returned to service.

The Yarkov mammoth 1999: In Siberia, a Mi-26 lifted a frozen block of earth weighing around 23 tonnes, with the remains of a woolly mammoth, out of the permafrost and flew it away for further study – pictures that went around the world.

Afghanistan 2002: A chartered Mi-26 recovered a US Chinook (MH-47E) that had made a forced landing in the mountains – the Soviet-built helicopter carried the American heavy-lift helicopter as an external load over hundreds of kilometers.

Sichuan 2008: After the severe earthquake in China, Mi-26s hauled construction machinery to landslide lakes that threatened to burst, so that drainage channels could be dug there.

Lake Geneva 2009: A Mi-26 lifted the hull of the racing catamaran Alinghi 5 out of the shipyard hall in Villeneuve in the canton of Vaud and set it down on Lake Geneva – one of the type’s rare appearances in Central Europe.

The history also includes dark chapters. In August 2002 a fully occupied Mi-26 was hit by a missile over Chechnya and crashed; with over 100 dead, the accident counts as the deadliest in helicopter history. Other aircraft were lost in war missions and accidents, for example in 2009 in Afghanistan, where a chartered Mi-26 was shot down.

Who flies the Mi-26?

The largest operator is the Russian armed forces. Added to that are civil Russian companies such as UTair as well as the Ministry of Emergency Situations. In export, the Mi-26 ended up with the armed forces of Algeria, Kazakhstan, Jordan, Venezuela, Mexico and North Korea, among others. India operated the type for a long time with its air force, as did Belarus, Ukraine and Peru; how many of these aircraft are still active varies greatly by source. In China, a civil operator uses the Mi-26T for heavy-lift and disaster missions.

The Mi-26 also used to be deployed in the West: charter companies brought it to Europe for heavy-lift jobs, South Korea procured civil crane versions, and the United Nations hired aircraft for missions in Africa. Since the sanctions against Russia from 2022, using Russian helicopters in the EU has been practically impossible.

Region	Chance of success	Why
Germany, Austria, Switzerland	very low	No operators, charter from Russia effectively ruled out
Russia and Belarus	high, but delicate	Home of the type; strict photo rules at military facilities
Kazakhstan, Algeria, India	low to medium	Military operators, sightings mostly at bases or parades
Crisis areas and UN missions	situation-dependent	Occasionally leased aircraft for logistics

How to recognize the Mi-26 at once

Actually the Mi-26 can’t be mistaken. But if you only have a photo from a great distance or see a heavy-lift helicopter on the horizon, you can narrow it down reliably in three steps.

Photo tips for the giant

Should you run into a Mi-26, every frame counts. A few things help.

• Make the rotor visible: With a very short shutter speed the rotor looks frozen and the helicopter seems to be crashing. Longer exposure times with panning show the rotor disc as motion. How to find the right speed is explained in the article Photographing propellers.
• Bring in a size comparison: People, vehicles or the external load make the dimensions tangible in the first place.
• Bring a wide-angle lens: With a 32-meter rotor disc, the Mi-26 hardly fits into a telephoto frame up close.
• Stand to the side: In profile, the relationship between fuselage, tail boom and rotor shows best.

The guide Spotting helicopters collects general tips for rotorcraft. How to identify military transport aircraft in general is covered in Recognizing military transports – there you also meet giants such as the Antonov An-124 or the Ilyushin Il-76, which likewise stand for heavy-lift transport.

Tracking the Mi-26 online

Many Mi-26s don’t transmit publicly visible position data, military aircraft above all. Civil examples occasionally show up with the code MI26 in ADS-B networks. Unfiltered community trackers show more there than commercial services. How you find military flights there and what the data mean is explained in Tracking military aircraft online; tips specifically for rotorcraft are provided by Finding helicopters on the flight tracker.

Anyone interested in the history of rotorcraft in general will find a large collection in the Helicopter Museum Bückeburg – whether a particular type is on display there or elsewhere, you best check directly with the museum before your visit.

Conclusion

The Mil Mi-26 is a superlative on rotors: the largest production helicopter in the world, built for a country where roads are often missing, and famous for loads nobody else could lift. For spotters in Central Europe it is a legend today, known more from videos than from firsthand experience. All the greater is the moment when you do get it in front of your lens once.
