(Creating this thread because existing KF-X discussion is highly fragmented.)
Korean media is reporting that the twin-engine C-103 design has been endorsed in a high-level meeting of Korea’s Joint Chiefs of Staff, chaired by the Minister of Defense. Bids are expected to be solicited in the coming weeks, with development beginning in earnest by the end of the year.
“The JCS formed a task force to review the costs, requirements and development schedules for the KF-X over the eight months,” JCS spokesman Eom Hyo-sik said. “As a result, the task force reached a decision that a twin-engine aircraft is a right choice as it meets future operational needs and can help catch up with neighboring countries’ aircraft development trends.
Given the potential development period for a twin-engine jet, the spokesman said, the KF-X jet’s initial operating capability is to be scheduled for 2025, a two-year delay from the original goal.
So we’re probably looking at an aircraft developing between 41,000lb (2xEJ200) and 52,000lb (2xF414EPE) maximum thrust.
On the supposed economic and technical rationale for a twin-engine design, I repost the following from an earlier thread:
The only way I can make sense of the claim that a twin-engine design has better long-term economic feasibility is if ROKAF is thinking ahead to replacing its F-15s also. If KF-X is a single-engine project powered by e.g. F110/232 then using it as the basis of an F-15 replacement is out of the question and this will require another clean-sheet project perhaps even overlapping with KF-X. A twin-engine design in the class of e.g. Typhoon could more readily be scaled up in future, particularly if this is anticipated from the very beginning. Such an evolution could also map onto the otherwise curious notion of internal stores carriage arriving only with KF-X v2.0.
I do wonder about the choice of Lockheed Martin as foreign partner when it comes to building what amounts to direct competitor to LM’s own F-35.
Also, I wonder if Japan’s recent ATD-X rollout had anything to do with the decision in favour of the more ambitious twin-engine design. 😉

Indonesia factor may postpone KF-X project
음성듣기
By Kim Hyo-jin
Indonesia has failed to pay its annual share of expenses for a joint project with South Korea to develop high-tech fighter jets, an opposition lawmaker claimed Wednesday.
The claim prompted concerns the project, dubbed KF-X, could be suspended.

Tango III already put this on Aviation News thread, but I put it again in this thread on pointed out that the difference need from ROKAF for internal bay (to make it more stealthly) and Indonesian TNI-AU to have more longer flight endurance, does not mean that definetely there’re going to be 2 seperate version of KFX (with internal bay), and IFX (which use the space as additional fuel tanks for longger endurance), as the article stated.
The final design for Block 1 is not final yet, but from what I heard on unofficial report..the designers still try to find away to meet both ROKAF and TNI-AU need.

actually i havent said anything to the brochures. they’re fine.
but as for the other stuff. maybe you’re right.
You should totally support Bayar to create more dedicated threads out of fairness.
By: mrmalaya - 10th May 2017 at 17:16
No, I’m saying that for some reason, his Turkish postings seem to turn you from a calm reasoned individual into one who makes angry nonsensical statements that appear designed to start a fight. He may post too many brochures, but he also posts a lot of news items supporting their content and has yet to rise to your uncharacteristic provocation.
That is my point, and I am not the only one to have noted that the T-FX has just as much momentum and international importance/interest to it’s name in the past 24 hours as the K-FX, which is plodding along in its non-flying state.

Do you have to keep on posting those wildly unconstructive, strawman attacks Y-20? We get it. I hope the Moderator deletes this last page of comments.
By: Y-20 Bacon - 10th May 2017 at 16:53
so you saying you agree with his claims that the TFX is more mature and advanced than the fc-31 and j-20? lol
By: mrmalaya - 10th May 2017 at 15:56
The point I was making (incidentally) was that if Bayar’s Turkish fighter thread was closed down because it is not flying, then you can apply the same logic to this Korean programme, or the 6th Gen thread.
Given the amount of interesting information he is prepared to post (which is not all rubbish despite what J-20 Bacon claims), surely there is room for a Turkish thread a T-FX thread? I am very interested to hear about how the BAE/RR input shapes the project and this aspect of the programme makes it stand out.
I have been guilty of the same thing by the way. The number of threads I have started about Taranis/FCAS/next gen European fighters/defence white papers because they didn’t fit elsewhere or would get lost in the noise of F35 discussion doesn’t bear thinking about!

Back on topic guys, please 🙂

Every TF-X thread I started on the site has been shut down.
I had started threads on flying Turkish platforms as well (e.g. TAI ANKA MALE UAV, TAI Hurkus-C Coin aircraft etc) and they too have been shut down.
So I wouldn’t bother as the decisions are politically motivated.
Its a shame but it only reflects on the site and its reputation.
Look again.. there is USAF and F-35 thread. VKS and PakFa thread. PLAAF and J-20, but most of the time its only one thread per country.. deal with it.
Besides if you want to talk UAV’s, there is a general UAV thread as well here.
Recommend you do not come on here all green and fresh, starts complaining and demanding.
Moderators has explained why you only get to have one thread, Turkish AF. It should suffice.
By: MSphere - 10th May 2017 at 14:19
Do you want me to list how many threads Boeing, Lockheed Martin, Saab, KAI etc have on here?
I can’t see a single thread on Boeing, personally.. or on SAAB.. not even on LockMart..
Why should we ignore new Armed MALE classed UAV systems, new COIN aircraft, new 6 ton helicopters etc if we are talking about defence technologies?
I cannot see separate threads on PC-7, PC-9, PC-21, Super Tucano or KT-1, either.. why should I discuss your Hurkus?
I don’t give damn about it and even less I give damn about your nationalistic pride..

No one is creating threads for “everything TAI churns out”. This is an aerospace forum and we discuss new technologies.

You got the Turkish Aerospace thread.. that’s enough.. no one needs to have a separate thread on everything that TAI churns out..

Y-20 Bacon, You seem uncommonly perturbed by the suggestion that Turkey contributes anything to the aerospace/defence world. For what its worth, I disagree with you and the moderator on the subject of the TFX thread. You got that closed because it was about an aircraft that is yet to fly.
What are we discussing here then? You are not as vexxed by a Korean LM clone, so I wonder why the Turkish plane is so offensive to you.
Surely this korean fighter should not have its own thread?
By: Y-20 Bacon - 10th May 2017 at 08:08

Ah yes the Altay is an exact replica of the K2. NOT.
By: Y-20 Bacon - 10th May 2017 at 06:43
Usually the Turks seek assistance from the South Koreans and base their designs on the Korean originals.
not the other way around
Altay is just a K2 with extra wheels

The 30W T/R Module is GaN based and designed for active phased array radars.
http://www.aselsan.com.tr/en-us/press-room/Brochures/Microwave-Products/X_BAND_MODULE_ENG.pdf
ASELSAN has GaN HEMT on SiC growth technology and is working on greater than 50W X-Band TRMs.
This facility is dedicated for GaN technologies R&D by ASELSAN and it is the largest of its kind in Europe commissioned in 2015.

Turkey can call us up when they have 50W X-Band TRMs utilising GaN HEMT technology. Something that only the very most advanced institutes and companies in the US, Europe, and Japan have. Korea is trying to research these technologies through ETRI in conjunction with Korean companies that have experience in military radars such as LiGNex1 and Hanwha Systems.
The 30W T/R Module in the second image does look promising but is that GaN/GaAs based or something else?
