As you guys have pointed out this is why I consider Hürjet trainer to be of utmost importance over KAAN atm. Because our so called allies would probably not mind selling us 90 engines for trainer jets.
So if we later on, after building them all, should have the need to convert them to LCA (light combat aircraft) and we can do that with minimal work, then we can still fly and wipe our arses, even if just barely.
But like I said earlier, making the LCA, and then asking for senate permission to buy trainer jet engine is going to be much more difficult.
Yes 3-4 years ago I mention that kind of thing many times, here's one instance:
It is why I personally follow Hurjet project lot closer. The timelines are sooner, more things matured/maturing quicker for it.... and it will illustrate the ecosystem maturity to take forward with TFX.
i.e we will see good proof one way or another (of everything you mention having to come together) in timeframe some are getting into (somewhat unnecessary tone) debate about.
There is no need to overly-praise or overly-diminish a solid project that is in the flow of things right now (that we cannot judge in some close-up microsystem way).
Results simply can be monitored and followed and compared with the debate preceding it....there should be no rush to produce judgement in this juncture from relatively casual observers + enthusiasts.
As you can sense and find all the issues lot quicker with smaller aircraft (both internally and with outside suppliers) that still ticks the important boxes (jet propulsion, avionics, LCA weapons capability)..... a more nimble project that can pump out a quicker production run ASAP too.
Any issues surfacing there gives early detection of same issues with TFX later and it buys you some time to think and develop solutions for that, rather than get shortchanged and stuck later.
