And?
Like, it's a demonstrator that flew how many times I forgot?
Which doesn't even look like next prototype apparently (what it verified then, possibly of creating a jet? Hurjet did that, though not impressive enough for an election indeed).
It's guaranteed that development of engines goes smoothly and won't take, say, a Chinese detour of just 20 years?
And ot isn't exactly the likeliest scenario, because China had 100x Turkish resources, had a fully established industry, endless (hungry) Russian assistance and got it solved. At no point China was at a threat of war, and Turkish borders are always a source of surprises.
Can it even outlive Erdogan, who's personally invested in this whole endeavour, but who's on his last term?
And that across the whole spectrum of risks, when you can just bow a bit deeper, pay for f-35 and it will happily fly.
Like dreams are good, but a way simpler Altay is still a tank of the future simply due to Germany saying no. For a whole decade we hear this engine almost ready.
US can say no to engines at any moment too, and you're fighting only at a speed of airfield tractor.
