If the 2025 serial production (or rather LRIP) target is still there, it has to be soon I think. From the way that piece on Hürjet was written, it sounds like the second prototype is going to be the one to fly at higher altitudes, faster speeds and execute manoeuvres with high g loads and probably bunch of other stuff. That's a lot of testing to do in a year, maybe a bit more.
I love it when they don't overpromise and keep to their schedules!

LRIP in 2025 for Hürjet is very ambitious.

Comparable T-50 development from 2002:

2 static test ground units (20 months structural static/fatigue testing)
2 T-50 prototypes (trainer version 001, 002)
2 A-50 prototypes (LIFT version 003, 004)

- CDR passed in August 2000
- Assembly start prototype 15 January 2001
Assembly completed 15 September 2001​
Roll out 1st prototype 31 October 2001​
- First flight 001 on 20 August 2002
- First flight 002 on 08 November 2002
- First flight 003 on 29 August 2003
- First flight 004 on 04 September 2003

First supersonic flight 18 February 2003 with Mach 1.05 at 40,000 feet (41st flight of 001).

1,411 test flights in total until certification.

- LRIP contract for first 25 T-50s signed on 19 December 2003
- First 2 T-50 delivered to ROKAF on 22. February 2005

They simultaneously tested the trainer and LIFT version but the timetable gives a hint what amount of work & flight hours is needed before starting with LRIP.

By "design phase", I think they mean CDR is now complete for it and design is frozen. So second prototype can't be that far, we should see it soon. 27 consecutive flights with the first prototype is a great milestone.

CDR of Hurjet was completed almost 3 years (Mar, 2021). Whatever flying now is EMD aircraft. I remember when TAI released own schedule of Hurjet, the company noted that it would conduct TRR (Test Readiness Review) of Hurjet, yet they have never announced completion of TRR and just flew their EMD aircraft.

TAI will continue to conduct test flights until they achieve System Verification Review (SVR) and then Production Readiness Review (PRR). Only after that the company could conclude EMD phase and move on to Production & Deployment Phase, including LRIP.

Things has progressed a lot in terms of technology and tool in 24 years. The availability of powerful computers and AI has definitely helped TAI to shorten this timeline. Additionally, their experience from other aerial platforms also helps in this regard.

Digital twins, automation and virtual prototype tests can cut engineering time significantly. But AI and digitalization can‘t replace real flight tests.

6 KF-21 prototypes have a scheduled 2,000 flight hours until 2026. And Boramae was engineered with latest programs and connected digital ecosystems for highly automated smart production.

But 2,000 flight hours are 2,000 hours to be absolved even for a digitalized fighter design. That‘s what KAI learned during T-50 development how meticulous industrial leaders like Lockheed Martin do it.

Regarding experience: Hürjet is TAI‘s first time developing a supersonic fighter aircraft from start to finish.

Let Hürjet move to armed version already, we don't want to lose more LCA opportunities after the lost Malaysia deal. We tasted palm oil for absolutely nothing, gives me stomach ache.

Hürjet development program cost is $1+ billion.

"-With a budget of more than $1 billion, this project is Turkey's first national manned supersonic jet aircraft. Development and maturation work continues unabated.
TAI Deputy General Manager Prof. Dr. Fahrettin Öztürk"

They will need a lot of Hürjets sold to justify that development budget, unless it is priced into KAAN. But afaik, TAI paid for it out of their own pockets.

They needed Hürjet, reseach, development and experience to develop Kaan. The real deal will be made with Kaan.

I know the argument for it, but still 1bln € is a lot.
Hope they can sell 100-200 Hürjet trainers and armed jets to reimburse some of that.

Still waiting for a visual on the LCA version.

First, I would re-paint it. Right now, they look like Solo-Turk, Fun Park jet. Not a Killer jet.

T-50 jets sold to S Korean armed forces have a price tag of around 40-45 million dollar a piece.
But the Polish are paying 2.3 billion for 36 T-50 planes . So export cost , probably including ammo and parts etc is around 80-85 million a piece.
Hurjet, when ready for export in both armed and trainer format should attract a similar price, if not a tad less for our lower production cost base.
So recovering a billion dollar development cost is not a big deal. The important point is being able to freely, getting the engines for the planes to achieve sales to countries we want to sell.

Yes, but if TSK doesn't buy and combat test them, then we can't get the sales to start. Also we don't even know if we will get export permit from all foreign sources.

Perhaps it's easier to export trainer jet that can be transformed to combat plane, once they're in the hands of nations that buys them. A little like how Germany transformed delivery planes to combat planes during ww2

I'm not nearly as optimistic as you are mate. I would bet that we will not be allowed to export armed version of Hürjet with F404, and, South Korea can finance those sales themselves, which is quite enticing, while we cannot. And not to mention, it is a very congested field Hürjet has to make an elbow room for itself. On top of these, we don't even have a mention of an engine project that would fit Hürjet. I expect us to buy enough Hürjet to cover TAI's costs but I'm sceptical about it selling like hotcakes.

İts also investment in human resources. Spending 1 billion in national aviation is nothing comparing other expenses of government.

If we have to make an engine to fit Hürjet it wouldn't be in GE's best interests, so they better sell an engine for it than not. I would also consider making a twin engine plane with the upcoming TF10.
