We do have a proposal made by Antonov's former President and Chief engineer Dmytro Kiva.
This was then submitted to the Ukrainian Government, but the ESOCA project's first phase is in fact to study all the possibilities, so we will likely have to wait until next year.
This is the proposal:
– The aerodynamics and the layout of the aircraft shall be based on the An-124-100.
– And the engines should be either the British Rolls Royce or the American General Electric.
– Install a modern “glasscockpit” cockpit with navigation equipment for the pilot (Thales, Honeywell).
– Replace some equipment and systems with European and Western ones. Transfer project documentation and paper technology to digital.
– The pressed wing panels, 28 meters long, must be replaced with European-made structure.
– Work on new modernized aircraft should be carried out by Airbus, Antonov and other European companies.
– The wings of the aircraft were to be produced in the UK, parts of the fuselage in Germany, parts of the units at Antonov and final assembly in France.
– The development of this updated aircraft will take 4-5 years and will cost approximately $3 billion.
Note that this is of course a proposal aimed at western nations in general, but since ESOCA is an EU program all the US and UK made components are of course to be excluded.
I personally believe that the choice will be to develop a new aircraft.
The last AN-124 was built 20 years ago...
