Mil Mi-8 / Mi-17

Updated: October 2026 – A dull, heavy clatter, a bulbous fuselage with big windows, and above it a huge five-blade rotor: if you travel in Eastern Europe, Asia or Africa, you often hear a Mil Mi-8 before you see it. No other helicopter has been built in such numbers, and hardly any flies in so many countries. For German spotters the Mi-8 is also a piece of East German aviation history. On this page you will learn how to recognize it, how to tell it from the Mi-17 and where you can still get it in front of your lens today.

What is the Mil Mi-8?

The Mi-8 is a twin-engine medium transport helicopter from the Mil design bureau in Moscow. It was developed in the early 1960s as the turbine-powered successor to the Mi-4, which still flew with a radial engine. The first prototype, the V-8, took off on June 24, 1961, still with just one engine. The twin-engine V-8A followed in 1962 – it became the model for the production version. From 1965 production ran at the Kazan helicopter plant, and the plant in Ulan-Ude in Siberia joined later. Both sites still build the family today.

The basic concept has remained unchanged to this day: two shaft turbines on top of the fuselage, a five-blade main rotor, a spacious cabin with room for 24 people or cargo, and on the transport versions a large rear ramp door for loading. The crew usually consists of two pilots and a flight engineer. For comparison: the French SA 330 Puma from the same era is much smaller and has four rotor blades.

Exactly how many Mi-8s were built depends on how you count. Over 12,000 aircraft is commonly cited, while other sources reach over 17,000 including all Mi-17 offshoots. The sources agree that the family is the most-built helicopter in the world. The biggest operator was the Soviet Union itself; successor states, allies and export customers on every continent were added.

The family: Mi-8, Mi-8MT, Mi-17 and Mi-171

Over six decades the basic design has spawned numerous versions. For identification in the field, it is enough to know the broad lines.

Mi-8T is the classic transport version with Klimov TV2-117 engines. It has round cabin windows and the rear ramp door. There were also passenger and VIP versions (Mi-8P, Mi-8S) with larger, rectangular windows, as well as flying command posts like the Mi-9.

Mi-8MT, or Mi-17, is the second generation. From the mid-1970s the airframe received the more powerful TV3-117 engines as well as the rotor and gearbox of the Mi-14 naval version. The prototype flew in the mid-1970s, and the export designation Mi-17 appeared from the early 1980s. The most important external change: the tail rotor moved from the right to the left side, where it works more effectively.

Mi-171 and Mi-172 are newer offshoots: the Mi-171 is the export version of the Mi-8AMT from Ulan-Ude, and the Mi-172 is a civil passenger version from Kazan. The modernized Mi-171A2 has received certifications in several countries, including India and South Korea. Armed variants such as the Mi-8AMTSh, or export Mi-171Sh, carry rockets, cannons and anti-tank guided missiles.

The Mi-8 in the NVA

For German spotters the Mi-8 has a special history. In East Germany it was the standard transport helicopter for decades. At the end of the 1980s the NVA air force had almost a hundred Mi-8s on strength, and there were more in army aviation and the Volksmarine. They were used for troop transport, liaison flights, rescue, as VIP helicopters for the political and military leadership and as flying command posts.

A special case is the Mi-8TB: an armed and additionally protected version of the Mi-8T that, according to some sources, could carry rocket pods and bombs. That is why the abbreviation TB is often read as “transport bomber”; the figures on the exact origin of the version differ. Alongside them flew attack helicopters of the type Mi-24, which were often organized in the same large units together with Mi-8s.

With reunification on October 3, 1990, the aircraft passed to the Bundeswehr. Some Mi-8s kept flying at first, among others in a helicopter squadron of Air Transport Wing 65 in Brandenburg-Briest, which emerged from the former Transport Helicopter Wing 34. The wing existed only from 1991 to 1993. The helicopters taken over received Bundeswehr serials in the 93+xx range – how such serials are structured is explained in the article on registrations of Bundeswehr aircraft. After that the type disappeared from German military service.

The three features that are enough to identify it

Among the large transport helicopters the Mi-8 is comparatively easy to identify. Three looks are enough.

How to use such features systematically for all helicopters is explained in the guide How to identify helicopter types.

Mi-8, Mi-24, Puma or CH-53?

The most common mix-ups happen with other helicopters of similar size. The finder helps you narrow it down.

A special case is the huge Mi-26: it also comes from Mil, but has eight rotor blades and is much larger. And you will never confuse the CH-47 Chinook with its two tandem rotors anyway.

In service worldwide

The strength of the Mi-8 is its robustness. It is considered easy to maintain, tolerates rough conditions and flies from unpaved sites. That explains why it can be found in so many countries – from Vietnam through Central Asia to Latin America. The Mi-8/17 is considered one of the most widely used helicopters of all.

Militarily it flies as a troop transport, medevac helicopter, weapons platform, command post and electronic warfare platform. In civil use it carries personnel and cargo into regions without roads, supplies oil rigs and research stations, carries external loads on the hook and fights forest fires with water buckets. The US also bought Mi-17s – not for its own forces, but for the Afghan army, whose crews already knew the type.

In the war in Ukraine both sides use the Mi-8 in large numbers. For spotters that means one thing above all: in Russia and Belarus, photographing military aircraft is strictly regulated and can have serious consequences. Before a trip, be sure to read the article on photography bans in Russia and Belarus.

Where to see the Mi-8 in Europe

In active service the Mi-8 has become rare over Germany. Every now and then Mi-17s of Eastern European NATO partners turn up at exercises or air shows – when and where is hard to predict. How to follow military movements online and why many helicopters do not show up there at all is explained in the article Tracking military aircraft online.

Museums, on the other hand, are reliable. Several museums in Germany and neighboring countries show Mi-8s from different eras:

Place	What you see	Why the visit is worth it
Berlin-Gatow	Mi-8T (93+14), Mi-8S (93+51) and Mi-9 on the outdoor grounds	NVA history with later Bundeswehr serials
Hermeskeil	Mi-8 next to Mi-2, Mi-4, Mi-14, Mi-24 and the huge Mi-6A	Almost the whole Mil family in one place
Kraków	VIP Mi-8 that, according to the museum, carried Pope John Paul II	A piece of Polish contemporary history on the outdoor grounds
Helsinki-Vantaa	Mi-8 and Mi-4 of the Finnish armed forces	Can be combined with spotting at the airport

Gatow also has its own spot entry: Luftwaffe Museum Berlin-Gatow airfield. And if you are already in Kraków, the Polish Aviation Museum has one of the largest Eastern Bloc collections in Europe.

Photo tips for the Mi-8

With a rotor diameter of over 21 meters the Mi-8 is big, and in a museum you often stand close. A few points help.

You can calculate in advance when the light works on the outdoor grounds; how that works is explained in the guide Planning the sun position for your photo spot. General tips for photographing rotary-wing aircraft are in the article Helicopter spotting.

Common mix-ups and how to rule them out

Conclusion

The Mi-8 is the workhorse among helicopters: robust, spacious and built in countless versions. For identification, five rotor blades, fixed nosewheel gear and the rear ramp door are enough; the side of the tail rotor then separates the Mi-8 from the Mi-17. In Germany it is above all a piece of NVA history that you can experience up close in Gatow and Hermeskeil, while worldwide it remains in service in large numbers.
