Earlier this month, Russia said it will resume the production of the Antonov An-124 jet, which is still one of the world's heaviest cargo airplanes.
Ukrainian state-owned aircraft maker Antonov has said the construction of the jet without its participation is inadmissible since the company has all the rights and all the documentation for the aircraft.
Russia says it has the rights and the new aircraft will be significantly modified to meet the modern requirements and will likely come under a new brand. Now, Aviastar-SP is seeking a partner to evaluate its capability to rebuild the jet.
Russian officials have said the renewal of An-124 is a feasible task. "If we talk about the resumption of their production, this is an extremely difficult, but solvable task ", said Aleksey Rogozin, Vice-President for Transport Aviation of the United Aircraft Corporation (UAC).
The Antonov-124 can carry super-heavy and oversized cargo up to 120 tons across 4,500 kilometers at a height of up to 10,000 meters. The jet completed its maiden flight in December 1982 and entered service in January 1986. The aircraft is 36m long and 4.4m high; it can operate under 60°C below zero and 45°C above zero.
