Regarding dumping and China's exports. The difference is that military jet purchases are not an ongoing purchase. China can (could) continue selling the same things to countries year on year. Sure with military jets there are add ons, maintenance and so forth but the purchase itself is a once a generation thing. If Vietnam buys 2 squadrons of these, they aren't going to keep coming back every year to buy more.Here's another thought:
In 2014 the Russian ruble stood at ~32RUB to 1USD. Now it's ~74RUB to 1USD.
30 million USD is 2,2 billion rubles in 2021 which is 70 million USD at 2014 rates. That's what the price would be if the ruble was still floating per pre-2014 rules. 70 million per plane is plausible from what I've seen in the presentation. Especially is things like engine or weapons integration are not included in the baseline version but are part of the second part of the contract i.e. "maintenance" under Matriyoshka.
Russia does not need to import almost anything for its weapons since they are largely self-sufficient, especially since 2014 and the sanctions. Thanks to Su-57 they have everything they need. Just build a smaller airframe and stick a single engine instead of two.
This means that for the purpose of aggressive export strategy they can price their exports in rubles but denominate them in dollars - meaning they will effectively transfer the benefit of weaker ruble directly onto the customer. It's not a very sustainable strategy for the entire contract but for the thing that matters in politics - the tender for the sale of the aircraft that does not have to involve hard LLC figures....you see where I am going with it?
Russia can "dump" the price of their jets by keeping them exactly at the natural market rate, and they can dump them by more than half.
This is - if you haven't noticed yet - Chinese approach to international trade competition. It worked wonders for China so why wouldn't it work for Russia especially that they are not the ones doing the rate-fixing. It's the western markets dumping the ruble.
Another thing that might play into this is why Russia was keeping their prices higher than the possible minimum in recent years - to gain hard currency reserves. Russia was selling at higher prices because that's how they got ability to gain currency which was denied to them through sanctions. Now they have perhaps other priorities. Perhaps they decided that for high-end and in-demand systems they will keep the price but for this particular product it's going to conquer the markets on price alone? It is not impossible. And in terms of strategic play it is not dumb either.
It's just that this kind of historic irony is almost too ironic to be possible. Which is probably why I kinda want it to be true. I prefer my world to be an absurdist comedy of errors and this really looks like it.
And there's one more thing - the name. Checkmate in English means checkmate but in Russian шахматы means just the game of chess. The name - for what it is intended to signal - doesn't work in Russian. It's either a brilliant idea or a hilarious rookie mistake. Either way it's too good to be true so I want it to be true.
If the price doesn't include the engine it's not really an apples to apples comparison. I don't think the Russians are trying to scam anyone. Countries who are interested will have a number of offers from competing manufacturers which will include armaments, training.
Isn't chess just "шах" in Russian?
