In a military context, this vulnerability was unacceptable. Any significant maintenance, repair, or modification would render the world's largest cargo plane grounded for an indeterminate period.

The most visually striking alteration was the addition of a second fuselage pod, effectively grafting an entire additional cargo hold onto the original aircraft. Its payload capacity of 250 tonnes and its cavernous 43.
The supply chain for the specific components, such as the D-18T engines and the unique structural alloys, has long since been dismantled following the collapse of the Soviet Union. Deconstructing the An-225 Mriya's Original Design To understand the significance of a second An-225, one must first appreciate the staggering achievements of the original.

Operational and Economic Considerations Beyond the engineering challenges, the operational and economic viability of a second An-225 is questionable. This modification, coupled with the addition of a second tailplane and the incorporation of all six engines from an An-124 plus two more from a spare, resulted in an aircraft with a maximum takeoff weight of 640 tonnes.
