The main body has finally been assembled together.
Also note the second KFX in the background

Space for where the two weapons bay would be. But this version will not use it for now. the internal bay is for future versions.

I'm curious if all 3 would be flying. Like.. one could be a static test frame.

I would be surprised if all three would be flying prototypes, at least one should be left out for static testing. Though I wonder how many prototypes are being built of the KFX?

Havent heard of any figure. Except that one would be for Indonesia so it would be at least "N+1" I would expect something like 10 tho. Mainly for risk reduction, and to help spreading the development costs even more.

Any information of F414-GE-400KI?
How would it differ from existing variants?
Would it use any of tech insertion that was going to happen on a production 414EPE?

From what I understand it is equivalent to the standard -400 model but just assembled by Hanwha with some parts made under licence.

i think this aircraft will be an ultra expensive program, highly limited to South Korea at the most, produced in small numbers at a very high price like the F-2 from Japan, they will need to pay royalties to Lockheed and going to be limited for exports to do not compete with F-35, honestly not a very original nor beautiful aircraft.

I prefer Rafale, well just kidding i like more Rafale, but well that is just my point of view not necesarelly the truth

rather than spend money to complete the project with Korea and advance their own domestic industry
Indonesia prefers to import bits and pieces of various aircraft. a few rafales here? a few typhoons there? a few su-35?


South Korea is in talks with Indonesia about a joint project to develop a next-generation fighter jet, the head of the arms procurement agency said Tuesday, amid speculation that the Southeast Asian nation wants to quit the project.

Indonesia agreed to partner in South Korea's KF-X project aimed at developing a new fighter jet by 2026, and promised to shoulder 20 percent of the total development cost of 8.8 trillion won (US$7.3 billion), or about 1.7 trillion won.

But Indonesia stopped making payments after investing 227.2 billion won, with around 600 billion won overdue.

"We are in the process of sounding out each other's position," Kang Eun-ho, chief of the Defense Acquisition Program Administration, said during a press briefing. "We will elaborate in detail when the time is right."

Indonesia's initial goal was to procure aircraft for its air force and advance the country's aerospace industry through the partnership but foreign media have been reporting that the Southeast Asian nation is now pushing to sign a deal with France to purchase new fighter jets.

Uhh, watcha talking about "paying royalties to LM"? If anything, you're talking out of your ass. Their role in this program is limited to technical assistance, which is an offset deal included in the 3rd F-X program that led to the procurement of F-35s, thus LM as TAC.

Also it is a well known truth that a country who could afford and would be granted access by the US congress to buy F-35s would not buy this plane. And that's not that great of a deal. There do exist countries to whom US would be hesitant or straight up decline the sales of F-35. KF-X is meant to compete in thoses markets. Lastly if anything, export isn't and will not be the primary goal of this program.

The most important part is creating a domestic platform. ROKAF's plan is to replace KF-16s with further development of this aircraft so your F-2 anology is not really fitting.

Also if you want to see something beautiful you've gotta go to design schools not look out for fighter planes. Giving biased or outright wrong thoughts based on your personal preference isn't really productive.

Indonesia's plan to purchase F-15EX, Rafale jets 'separate' from KF-X joint figther development program
thats good.. I think.
but that begs the question
1. If they can afford to buy F-15s and Rafales, then why can't they afford to pay their share of KFX development? they are behind schedule
2. Do they really intend to keep operating hawk 200, f-16s, Su-27, Su-30, F-15, Rafale, and KFX? I feel something has got to give.

Should the hawk be retired since its the least capable and oldest of the group?
what about the Flankers? they seem relatively new but there are spare problems according to stealthflanker.

thats good. I think its imperative that Indonesia stays in.
Unlike the F-15, Rafale, or Flankers.. the KFX is something Indonesia actually has some ownership of. Like the CN-235
it's important for their domestic industry

I hope its a type they can standardize around in the 2030s. Alongside whatever they decide to go with.. F-15s, Rafales, more F-16s or Flankers.
but perhaps reduce a few types. not sure which.

supposedly the KFX is to replace the Hawk (i thought the Golden Eagle was supposed to do that)

I think Indonesia has been purchasing many different defensive equipment from different countries due to their trauma of the past arms embargo which was quite impactful to their ability of maintaining their equipment and purchasing new spare parts.

Hence nowadays, they want to "spread their investment". Now, I don't know if this is the right call because ofc standardisation, cross-compatibility, and streamlining the logistics are important but at least this may give an insight on why they want to have some "varieties in their inventory".

Not sure though idk.

It would probably be the Flankers which were purchased in the 2000s that they would retire, could be a premature one as well, given the growing difficulties surrounding its maintenance due to various reasons and their shift to STANAG weaponry. I've heard somewhere that those Rafales are meant to do that. One's got to remember that during 2018 they've only planned to procure 11 or so Flankers, which are now replaced with plans to buy 8 Eagles. Going extra with those Rafales are in order to replace the Flanker AFAIK. I don't think that they will ditch the Flankers right away though, as they are modernizing it.

T-50 replaced the normal trainer variants of the Indonesian Hawks and the Indonesians plan to upgrade it to FA-50 standard so that it could also do some LIFT role.

IF-X replaces the Hawk 200 variants they operate and the F-16s. Their F-16s are either from the late 80s ~ early 90s (block 15 models) or refurbished (block 32 models) so by 2030 it really needs some replacement. Now they're upgrading the block 15 models with some new avionics and structural reinforcement, which is not the case for the refurbished block 32 models, so those block 32 Falcons would be the ones to get replaced first should the IF-X program continue.

I am happy to be corrected if anything's wrong.

Lockheed Martin has reportedly given (I imagine that means sold) 8 of the 12 technologies that KFX team required. Now - it's perfectly possible that a tech transfer contract has an article in it where the seller retains control of who the product of the technology used to make the plane goes to. Exactly the same issue is now being used against Chinese chipmakers, for example. They can't sell their chips because the machines that make the chips are not indigenous, even though the chips themselves are.

Furthermore, KFX has US engines. So there might be some influence of various US parties through that piece of leverage as well. "You want to sell KFX to country XYZ? Sorry, no engines for those airframes"

And in all likelihood there are bound to be some more US sourced systems, besides engines, to be used in KFX.

So... overall, I don't think KFX will be selling a lot outside the two countries that ordered it. If for some reason US can't sell F-35s, F-18s, F-15s or F-16s to that country - then sure, those might sell. But when one removes countries that might otherwise be interested in those types - there aren't that many affluent countries left that would be interested in KFX.

For sure none will be sold to Kim's North Korea. Even with Trump the 2nd.
But then, nothing rational would prevent some to be sold in South America, Europe or Africa..

Most of the avionics are Korean but as you suggest, there are indeed some critical components like Cobham's conformal antennas or UMS MMIC modules which are being imported as well.

Talking 'bout hat UMS MMIC, it will be replaced with the Korean one which is currently at TRL 7 (and has more peak power) once the mass production begins, so that's at least one less concern. From what I know, the Korean avionics engineers opted for Qorvo MMICs at first but soon changed to UMS due to US restrictions so there are already some hurdles concerning the US EL restrictions which are present.

Tbh iþt ain't really new that Korean defense manufacturers doesn't get to sell their weapons where they want to due to imported components or techonolgical origins. For example they wanted to sell their ALQ-200K jammer pods to, was it Pakistan? I can't remember exactly but to a certain central Asian/middle eastern country but got denied by the US because the technology is based on the ALQ-88K jamming pod, which was developed with transfer of technology from the US. Another case was when US denied the sales of FA-50 to once again another central Asian/middle eastern country.

Even if we suppose a case in which KF-X is developed completely by Korea all alone without any help or tech from LM/US and is completely indigenous from nose to tail except for the engines, US would obviously have control over where the KF-X would able to be exported and where not. It doesnt really matter if this jet has one US component/tech or hundreds as long as it is powered by an American engine.

Also there were some difficulties settling down the terms on which Indonesia gets to participate in the program due to those tech from the US. Obviously there is no transfer of amy technology Korea gained from the US to Indonesia as it stands and rightfully so.


There's also the problem you are mentioning about US' denial of its sales in those markets where it competes with US products. From what I know that was also the problem the Gripen was faced with during the early days when A/B models were being produced.

Thinking further about those cases where the US can't sell its own fighter jets, I could think of :

1. Case of Brazil, where they are not necessarily an adversary or anything but incidents occur where US is in trouble and tries to save face.

2. KF-X is reasonably cheaper than the US counterparts (hey, only supposing such case. I don't claim it will be so don't hang me) that the US can't oppose its sales.

3. US being concerned of their 4.5 gen technologies being leaked or are hesitant because of the diplomatic relationship with said country that's not neccesarily bad nor good so they allow the KF-X to be sold imstead which is still essentially an aircraft with foreign avionics.

If I could say anything, all those cases I could come up with are extremely rare. So it would probably compete with other US made 4.5 gen aircrafts.

Then again later Gripens had close to none US restriction on Sweden selling their jets but were just not sold because it was too expensive for what it could do.

Talking about over seas sales prospects, I don' t really think there is a world where KF-X does super well in export market. It would rather struggle considering the fact that 4.5 gen fighters like the Super Bug and Rafale which has similar capabilities to their Korean counterpart would be well in production going into 30s and thus would have established supply chain and operating ecosystem as well as the reputation which the KF-X wouldn't have, say, at least for the first 5 years of its production. Maybe even 10 or more.

So all in all, I don't think that the US would put hard restrictions on its export as long as it complies to their foreign policy, just like in the case of Gripen. Again just like Gripen, it would rather come down to the question of "if this jet would be more favorable" than the French and American counterparts. Gripen had a hard time answering the question with "yes" and we'll get to see if that's the case for KF-X as well.

Also there is probably no chance where a country that could afford and would be granted the license to purchase the F-35 would buy this jet. So in the sense of not harming the US aviation industry, KF-X probably wouldn't be much of a concern because it was not born to compete with their biggest defense program.

off the top of my head.. some issues Koreans had

Argentina - they tried to sell FA-50s there. But it fell through. not because of US parts but UK parts. Last I heard the Koreans were trying to replace it with something local. But tbh.. not sure if Argentina can buy any western combat aircraft due to the UK relationship

Turkey - Turks Altay tank is basically a souped up K2 black panther tank. After Erdogan's foreign policy moves, the tank's progress has been set back due to unavailability of parts. They went back to the Koreans for help but the Koreans can't do anything as their own version, engine is German, and they use French for another part. two countries that are not Turkish friendly at the moment.

Nah, Altay wasn't really Korean's business anymore once the development was over. They have fulfilled all their obligations and was paid for. All that left was supplying some parts like suspension system to Turkey. Also nothing is French in K-2. It's a misconception because the autoloader looks similar. The only important part left that is imported is the Renk transmission. Koreans are having a hard time developing their own.

The actual problem Korea had with exporting armored vehicles that has German powerpack in it was when Hanwha tried to sell the K-9 to UAE. Last year it came close to inking the deal but didn't realise due to German restrictions of selling weapon related systems to this region.

It could be a problem for KF-X as well as it plans to use IRIS-T. The US hasn't let the integration license of AIM-9X and AIM-120, citing that there exists no aircraft with which the integration could take place. KAI is therefore planning to obtain integration license once they roll-out to prototype. Until then, it would remain an uncertainty and potentially and obstacle in its way to foreign sales.

sorry i was referring to Altay and the French armor it cant use anymore

Very good pace indeed


notice 3 prototypes in the line
here is a second video that shows the front shot and cockpit shot
View: https://www.youtube.com/watch?v=Gqrma7UBmTw


Screen Shot 2021-03-01 at 16.07.47.png
From the first video, you can see all 4 KFXs down the line being assembled

Screen Shot 2021-03-01 at 16.08.16.png
Turkey feathers!! not serrated though

Screen Shot 2021-03-01 at 16.09.14.png
from the 2nd video. close up of the seat.

wow, Turkey should have really stayed in this program and hopefully Indonesia can resolve their differences with KAI.

i also agree with VTOLdelicious, that its something Europe should have had already but I had a feeling that them going in the 4.5 route in the 90s/2000s reduced the chance of them going 5th gen, and why they're probably gonna skip to 6th gen.

But the KFX itself is a 4.5th generation aircraft (with later versions intended to evolve towards something more akin to a 5th generation aircraft).
Hence this is something equivalent to a Typhoon or Rafale but decades later.
Fair dues to South Korea, a proud achievement for their aircraft industry, but not something that the European (including UK) aviation industry needs or should be especially envious of.

^ i would assume it is likely to have a significantly lower RCS value
and later versions will have an internal bay.
You can see the bay space here, which is currently covered up by a panel for semi recessed missiles.

Seems to be the govt/KAI is doing some PR of some sort about once a month running up to the roll-out in April.

Here is the link to the highest res/most comprehensive set of images: https://bemil.chosun.com/nbrd/bbs/view.html?b_bbs_id=10044&pn=1&num=222629

Ah, apparently there was a press brief on the 24th of February but the embargo lifted today to mark the Korean national holiday commemorating Korea's struggle for independence.

As for any new important information:

KFX-001 is on course for roll-out in April and is at approx 92~93% completion.
They have done engine fit checks but will remove the engines to paint the aircraft
It will be painted on the 3rd of March in a dark grey reminiscent of the ROKAF F-15K's
2 and 3 will be completed by the end of the year
4,5, and 6 by the first half of 2022
The airframes 1~4 have been completed already (All Fuselage sections and wings joined)
This is not to mention the 2 non-flying static load and fatigue test articles which are also in production
The plan is to have aircraft 1 to 6 complete approx. 2200 test sorties between 2022~2026 to complete initial development, at which point LRIP will begin.
The EO-TGP and a2g munitions will only be integrated later between 2026~2028 as part of Block 2.

The AESA radar, EO-TGP, IRST, EW Suite, Engines, and APU have an indigenous content of 66% when averaged together
Specifically:
The overall target is to have the entire aircraft be 65% indigenous by parts value
While supporting systems such as simulators or maintenance/logistics systems will be at least 90%

There is a two-seater variant being developed in parallel and the number 4 and 6 prototypes will be of this type

The KF-X has a designed service life of 8000 hours
