Thanks for the update. I don't have time to check right now, so what follows is from memory mostly
I am sure some airliners will be produced soon in Russia. Why were the modern designs vulnerable to sanctions? Basically they incorporated many western elements/systems since they were much higher grade than Russian ones. Without them Russian airliners would not have been competitive with western designs. What does that suggest about the economics of the Russified versions?
IIRC Russia seized over 400 A320/B737 in 2021. Without proper maintenance many will have to be grounded soon, although normaI airworthiness regulations have been suspended to enable them to keep flying without proper maintenance.
I don't see Russia building enough airliners to keep up with groundings for several years. I suspect that only a handful of Russified airliners will be produced in the next 2-4 years. It is almost inconceivable that 1,000 airliners will be manufactured in Russia by 2030.
That is damaging to the Russian economy, all down to invading Ukraine.
I feel like you did not read my articles, they did say they have 10-15 years left to use the foreign aircrafts, 10 will be produced in 2025. 3 more years production will be 36 aircrafts, or it can be 72 if the demand is higher in the same production facility. so the plans look like 2025:10, 2026:10 2027:10 2028:36-72, 2029: 36-72, 2030:36-72. Assuming the news report came from late 2024 in 6 years they can produce 138-246 airliners. This is 6 years but their reliance for foreign aircraft is 10-15 years and you claim that over 400 airliners were seized to be used by Russia. I hate to say this but mathematically speaking they will meet the over 400 aircraft replacement demand in 2035 while still using some foreign aircraft that still have some service life left.
Miscalculations happen all the time like they will run out of missiles, they won't be able to produce their own cars, they won't be able to produce their own chips, they wont be able to produce their own airliners, they won't be able to start producing tanks and IFVs for this war, etc you get the picture. Another miscalculation that happened was after nuking Japan the US thought it would take Russia 10 years to make a nuke but instead it was a few years afterwards. Hitler and Napoleon made miscalculations to with some other superpowers before them to.
