Antonov An-990 -

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.

Where the An-225 had one fuselage, the . Two pressurized cargo holds ran parallel to a central passenger/crew module, all joined by a delta wing so vast its trailing edge was measured in hectares, not meters. To lift a projected payload of 990 metric tons (nearly triple the An-225's capacity), Antonov engineers reportedly opted for 14 engines —a mix of Progress D-18T turbofans on the wings and four reinforced Kuznetsov NK-32 afterburning turbofans (from the Tu-160 bomber) mounted on a revised tail fin for "assisted climb-out." antonov an-990

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." Officially, the An-990 never existed

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.
