Somewhere outside the Siberian town of Abakan, in the Republic of Khakassia, there is a packed-snow airstrip about 200 metres long. It is the only way to get into a village called Nizhny Kurlugash in the winter months. The strip is serviced, twice a week, by a single-engine biplane painted faded Aeroflot blue, with a 1,000-horsepower radial engine that fires up reluctantly in the cold and a maximum cabin temperature, according to its pilot, of about eight degrees Celsius. The aircraft is older than the pilot. It is, almost certainly, older than the pilot’s mother. It is an Antonov An-2, NATO reporting name “Colt,” and it first flew in 1947.

It is, in 2026, still the only aircraft in production anywhere in the world that can do what it does. Which is take off in less than 170 metres, land in less than 215 metres, carry a tonne of cargo or a dozen passengers, fly slowly enough to be passed by a hatchback on the motorway, and operate from a snowfield with no preparation other than someone walking the strip with a stick. The An-2 was designed when Stalin was still alive. The Soviet Union it was built for has been dead for 34 years. The radial engine technology it relies on hasn’t been considered “modern” since about 1955. And the airplane is still flying, still being maintained, and still — in Poland and China, sporadically — being built.

The Guinness Book of World Records once granted it the title of longest aircraft production run, at 45 years. (The Lockheed C-130 has since edged past it on that one.) It remains, by an enormous margin, the largest single-engine production biplane ever built. Around 18,000 of them came off Polish, Soviet and Chinese assembly lines between 1947 and roughly the early 2000s, and they have been flown, in numbers, by approximately 47 countries.

It is, in short, the airplane that refused to die.

A Biplane in 1947, Because the Job Required It

The story of how the An-2 came to exist is a small history of postwar Soviet pragmatism. In 1946, the Soviet Ministry of Agriculture issued a request for a small utility aircraft for crop-dusting, light cargo, ambulance and survey work in the vast roadless interior of the USSR. The specifications were demanding in a very particular way: it had to operate from unimproved strips, lift heavy loads in hot weather and at altitude, and be flyable by relatively low-time pilots. The market for such things in the West was being filled by monoplane utility designs — the Cessna 195, the de Havilland Beaver, the Noorduyn Norseman.

Oleg Antonov, then running a small design bureau in Novosibirsk, looked at the specification and decided that the answer was a biplane. This was a contrarian position in 1946. The world had moved on from biplanes. They were considered obsolete by anyone with a strong opinion about airframe trends. Antonov’s argument, defended at length in front of skeptical commissars, was that the job description — STOL performance from rough strips, with heavy payloads — was the same problem the Wright brothers had been solving, and the Wright brothers had been right: two wings give you more lift per linear metre, more controllable slow-speed flight, and more structural stiffness than a single wing of equivalent area. For this particular job, the monoplane fashion was wrong.

The first prototype flew from Novosibirsk on 31 August 1947. It performed exactly as Antonov had promised. Production began at a State Aircraft Factory in Kiev in 1949 and would shift, in 1960, to the WSK PZL-Mielec plant in southeastern Poland, which produced more than 11,915 of them by 1991. Meanwhile, the Chinese signed a licensing agreement in 1957 and began building their own version — the Shijiazhuang Y-5 — which is still in production today in low-rate batches.

The Handbook With No Stall Speed

Of all the technical oddities the An-2 carries, the one pilots talk about most is the fact that its operating handbook does not list a stall speed. This is not because Antonov forgot. It is because the airplane, properly handled, does not stall in any meaningful sense. The combination of the lower wing’s full-length leading-edge slats, the upper wing’s drooping ailerons, the slat-and-flap interaction, and the sheer biplane lift means that as you slow down, the aircraft simply mushes into a high-alpha descent and stays controllable.

The operating handbook’s actual advice for a power failure is to pull the stick fully back and keep the wings level. The leading-edge slats will pop out at around 64 km/h. The airplane will descend, under control, at a forward speed of roughly 40 km/h — about 25 mph. Which, for a fully loaded aircraft, is somewhere between an outstandingly slow approach and a barely-coordinated parachute descent. Pilots have demonstrated, repeatedly, that with a stiff enough headwind — say, 50 km/h — an An-2 can fly backwards over the ground. Slowly, but backwards.

This is not a stunt. This is exactly the flight characteristic the airplane was designed for: getting into and out of unprepared strips that nothing else can serve. Modern STOL designs — the Quest Kodiak, the Helio Courier, the Pilatus PC-6 — do similar work with monoplane wings and turbine engines. None of them match the raw slow-flight numbers of a stock 1947 biplane with a piston radial.

Forty-Seven Countries, Every Mission You Can Name

The An-2’s customer list reads like a postwar geopolitical census. Soviet air force, naturally. Every Warsaw Pact air force. North Korea, which still operates a significant fleet and famously trained its special forces to insert by An-2 because the airplane’s slow speed and low radar cross-section make it surprisingly difficult to intercept. Cuba. Vietnam. Mongolia. Most of the former Soviet republics still fly small fleets. Several African air forces took deliveries during the 1960s and 1970s. Yugoslavia. Romania. East Germany. Civilian operators across Eastern Europe used them as crop-dusters, paratrooping platforms for jump clubs, light freight haulers and bush taxis.

The airplane has been used to carry diplomats, to spray pesticide over Soviet collective farms, as a training platform for parachute regiments, as a smuggling aircraft on more borders than anyone wants to count, as an air ambulance into roadless villages in northern Siberia, and — in at least one documented case — as a flying classroom for early Cosmonaut survival training. It is the only certified aircraft in the world that can be flown on either avgas or, in a pinch, on automotive gasoline mixed with cooking oil. Mechanics in Mongolia have a long-standing tradition of using vodka as a fuel-system de-icer.

Why the An-2 Will Outlive Most of Us

The honest answer to “why is this airplane still flying in 2026?” is that the job hasn’t changed. The Mongolian steppe in winter is still the Mongolian steppe. The Khakassian dirt strips are still 200 metres long. The remote northern Russian settlements are still served, primarily, by short-field aviation. And the modern marketplace, for whatever reason, has produced exactly zero clean-sheet replacements for what the An-2 does. The Y-5 in China is the closest thing, and it is, structurally, the same airplane.

Antonov himself died in 1984. His design bureau, now based in Kiev, has spent the past 40 years building larger and stranger aircraft — the An-72, the An-124 Ruslan, the spectacular and now-destroyed An-225 Mriya. None of them have replaced the An-2. None of them were ever meant to. Because the An-2’s job — cheap, rugged, slow, useful — turns out to be the one piece of aviation that doesn’t really need to be modernised. The 1947 answer was correct. It is still correct. And on a snow strip outside Abakan, somewhere east of Novosibirsk, a faded blue biplane will fire up its radial engine tomorrow morning and do the job exactly as designed.
