Beyond the "An-990": The Mythical Future of the World’s Largest Cargo Planes

• Six engines — Progress D-18T Mk5 (300 kN each), later upgraded to super-cooled hydrogen turbofans.
• Twin tailfins — canted outward for wake control; a direct homage to the An-225.
• Double-bubble fuselage — two intersecting pressure cylinders create a massive, unbroken cargo hold 98 m long, 8.4 m wide, 6.5 m tall.
• 30-wheel main landing gear — 14 twin-wheel bogies down each side, steerable for tight turns on reinforced taxiways.
• Forward nose door — hinged upward (like An-124), plus a rear cargo ramp for drive-through loading.

Configuration

Runway Clearances:

Pilots must find massive runways with over 500 feet of side clearance to account for the immense wingspan. antonov an 990

Intelligence reports at the time suggested that the United States was exploring next-generation propulsion for transport aircraft. Not wanting to be left behind, the Soviet government initiated a black project designated "Izdeliye 990" (Item 990). Beyond the "An-990": The Mythical Future of the

Landing Gear Versatility:

One of the hallmarks of Antonov aircraft is their ability to land on semi-prepared or dirt runways. The An-990 design featured a complex, multi-wheel landing gear system to distribute its immense weight, theoretically allowing it to operate from airfields that would normally be off-limits to such a large plane.

Size Comparison:

The plane is so massive that other large aircraft, like a Boeing 747, can be carried on its back or look tiny beside it.
