Antonov An-990 ((top)) -

The landing gear, a nightmare of hydraulics, contained 64 wheels arranged in four independent bogie trains. Turning required a specialized tow-tractor and a five-kilometer turning radius. The only operational anecdote comes from a purported "leak" by a former Antonov test engineer in a 2012 forum post, since deleted. He claimed that a single prototype—registration CCCP-990100—was rolled out of a modified hangar in Kyiv in December 1991, just weeks before the fall of the Soviet Union.

Officially, the An-990 never existed. No technical manual, no wind tunnel model, no grainy black-and-white photograph has ever been authenticated. Yet, among post-Soviet aerospace engineers, it is a cautionary fable of "what if the constraints of physics were merely suggestions?" According to the lore, the An-990 was conceived in the late 1980s, a time of Soviet economic chaos but unchecked engineering ambition. The brief was simple: transport the heaviest components of the Soviet energy and space sectors—whole nuclear reactor vessels, sections of oil rigs, and disassembled launch vehicles—without disassembly, overland, to the frozen ports of the Arctic. antonov an-990

Today, with the real An-225 destroyed in the 2022 conflict, the ghost of the An-990 serves as a poignant, almost tragic symbol. It reminds us that sometimes the most incredible aircraft are not the ones that fly, but the ones that exist just on the other side of reason, waiting in the blueprint—a beautiful, impossible answer to a question no one should have asked. The landing gear, a nightmare of hydraulics, contained

The taxi test was a disaster. The weight of the central fuselage caused the asphalt of the taxiway to liquefy. The first and only "hop"—a 20-foot rise off the runway at 180 knots—reportedly shattered every window in the control tower and stripped the roof off a nearby maintenance shed due to the exhaust wake of the 14 engines. The aircraft landed immediately, its rear triple-fuselage joint cracked. Yet, among post-Soviet aerospace engineers, it is a

But the legend of the An-990 persists because it represents a pure, unfiltered expression of Soviet-era "gigantomania": the belief that any logistical problem can be solved by adding more engines, more wheels, and more wings. It is the aviation equivalent of building a pyramid—a monument not to practicality, but to the hubris of "because we can."

The solution was a grotesque masterpiece of radial symmetry.

In the pantheon of aviation engineering, the Antonov Design Bureau is synonymous with "big." The An-225 Mriya —a six-engine, 32-wheel leviathan that carried the Soviet Buran space shuttle—remains the heaviest aircraft ever built. But in the dusty archives of unbuilt concepts, whispered about in the hangars of Hostomel Airport, lies a legend that makes the An-225 look like a crop duster: the Antonov An-990 .
