Turkey has one more option othwr than SU57 now
Turkey has no intention of acquiring Russian aircraft in the near future. The only difficulty here is not just the acquisition of the aircraft. Appropriate infrastructure transformation, training and documentation, maintenance lines, avionics accesses, system-based enhancements, cryptology and comm between machines, etc. could require building an air force from scratch. Bringing it to operational level under force command could take longer than developing any new aircraft. Even if you leave aside the economic, political and geo-political reasons, it is not as simple as it is discussed here.
We will watch the rollout ceremony of the jet anyway. There isn't even a ready jet. Therefore, such speculations are useless. Let's first see the concept of Rostec and what standards it offers to the market under what conditions.
Countries like Vietnam and Argentina, on the other side , they already have geopolitics that could be Russia's natural market. But the real strangest thing is that while India's light and medium class combat jet projects continue, India is emphasized in these promotional activities.
By the way, I like Rostec's marketing strategy. If they can analyze the JSF well in terms of logistics control and political conditions; It can be an important factor in building an alternative military perspective to the US concept of joint platform.
