Well the problem with Antonov is they are too dependent on Russia for eg 70 % of component for An-148 comes from Russia , Antonov as a design bureau is good , they make fairly decent engine but major component is procured from Russia.
Russia had all the same problems the Ukraine has had with the ripping apart of their industries.
If the Ukraine wants to turn west then it can start looking west for partners to help its industry, and such a change can happen the night after an election of a government that is pro west and anti Russian and there are several of those in the Ukraine.
The question is should Russia gamble that ties with the Ukraine will remain good or get better?
Remember it was the Ukraine that was stealing gas meant for Europe which got the Russians blamed for erratic energy supply and accused of using energy as a weapon.
It is not rocket science... where the Ukraine and Russia are concerned they are now separate independent countries, so if a Russian company is making something that needs foreign parts it could look to the Ukraine, but then it could just as easily look to any other foreign country too.
The Russian military and Russian government should favour aircraft and material with all Russian components first, and if they are not good enough then licence production of the better stuff made in Russia should be the second option.
Foreign made parts should only be acceptable where the foreign made parts are made by a genuine ally like India or Serbia rather than a fair weather friend like the Ukraine.
The huge irony is that with all the rubbish about Russia being responsible for famines in the Ukraine as genocide is that Oleg Antonov was Russian. The policy to spread industry to the various republics was a Soviet policy.
If there is no Russia support Antonov will simply crumble be it military or civil aviation.
And if there was not support or customers for Airbus it would crumble too, but why would Russia care?
If Antonov crumble the Russians might consider buying it at a low price, but then Boeing or Airbus might consider it a cheap way to get their expertise too.
Russia could spend money bailing out Antonov and the Ukrainian shipyards by giving them work that could otherwise be done in Russia, but how can Russia be sure such gestures would even be appreciated in 10 years time or at the next election?
What is the point of helping the Ukraine now when you suspect when it is a little stronger it will leap into the arms of the west and turn its back on you at the first opportunity?
So any leader that comes in the future needs to take into account this factor , that Russia is a large market for Antonov products and they still source major components from them.
That has been the case since the Antonov Design Bureau was created yet in recent years during the coloured revolutions it wasn't important... the west was going to save them and the Russians were the source of all their problems and were holding them back.
It failed this time around but what about next time?
Yeah they have some Bulark D-30 upgrade program that improves D-30 fuel burn performance, might be worth for older existing IL-76
If the prices haven't changed then it might make economic sense to fit the upgraded engines rather than the new ones because the purchase price difference is probably more than the extra fuel burn costs and maintainence costs. More expensive engines will require more expensive components...
