Antonov An-990 [better] Info

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.

| Factor | Insight | |--------|----------| | | Projected 30 % lower cost per tonne‑kilometre than the An‑225 due to twin‑engine efficiency and reduced crew requirements (pilot + flight engineer + 2 loadmasters). | | Fuel Efficiency | Approx. 0.15 kg fuel / tonne‑km (including payload). This is comparable to modern wide‑body freighters such as the Boeing 777‑F when scaled for payload. | | CO₂ Emissions | Estimated 0.42 t CO₂ / tonne‑km , meeting emerging ICAO Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) benchmarks for heavy cargo aircraft. | | Lifecycle | Designed for 30 000 flight‑hour service life with a modular “mid‑life upgrade” path (e.g., new engine variants, avionics refresh). | antonov an-990
