Sadly, there isn't much info on it from the Ukrainian side either. Don't want to use the term *hush-hush*.
They used terms like 'overhaul' and 'modernization'. What, they installed seats that now have cushions & could recline...?
In Ukraine, completed the repair of the Pakistani Air Force IL-78 aerial refueling tanker
Honestly, I fail to understand what upgrades they could possibly do on those rust buckets.
As someone pointed out that it could carry upto 40 Tons of fuel. What good is that when it needs 20 Tons just to stay in the air.
