The USN Test Pilot School takes foreign students, I'm not clear if the USAF School does or not.

Latest iteration ... maybe !?

Looks like a cross between a F-15 and a F-22

Latest iteration is C108;

still, there is no publication for C108; OML is probably fixed at C108

Indonesia is reviewing its involvement in KFX and have missed their latest payment of $100 million. There doubts that it will pull out completely and hints that there may be some political motivations to attempt to get South Korea to order CN-235 MPAs.

ROKAF Pilots are being sent to United States Naval Test Pilot School (not USAF for some reason?) to become certified Test Pilots and Flight Test Engineers for the KF-X Programme.

Off topic: Why is the KF-X moved to the Postwar Subforum?

As a follow up: Aparently the ROKAF has been having exchanges with the

since 2014 as well: http://english.yonhapnews.co.kr/search1/2603000000.html?cid=AEN20180422002000315

Also KF-X Program news:

Structural test facility built for the future fatigue/durability testing of KF-X ground-test article.

KF-X flight software being tested on KAI-owned FA-50 test plane. Things like Auto-GCAS, Automatic way-point navigation, Automatic terrain following (Things that KAI hasn't developed for the FA-50 that the KF-X needs to be a front-line fighter)

KF-X 선진자동비행제어 기술실증 초도비행 성공
5월 11일 KF-X 선진자동비행제어 기술실증기의 초도 비행이 성공적으로 수행되었다. 본 사업은 항공기계통실 KF-X제어체계팀 주관으로 KF-X에 적용하기 위한 자동지상충돌회피, 자동자세회복, 자동경로항법 그리고 자동지형추적 기능과 같은 선진자동비행 기술을 독자 개발, FA-50 시제 2호기를 통해 사전에 기술 검증하는 사업이다. 자동지상충돌회피 기능은 조종사의식상실, 조종착각 등의 상황에서 항공기의 지상 충돌을 자동으로 회피하는 기술이며, 자동지형추적 기능은 항공기가 적의 레이더망에 탐지되지 않도록 초저고도로 지형을 추적하며 비행하는 기능이다. 또 자동자세회복 기능은 조종사의 버티고 (VERTIGO, 비행착각) 상황 등에서 항공기를 안정적인 자세로 회복하는 기능이고, 자동경로항법 기능은 자동으로 3차원 경로점을 비행하는 기능이다. KF-X 선진자동비행제어 기술실증 사업은 올해 7월까지 총 19쏘티(SORTIE, 단독 항공기 출격 횟수)의 비행시험이 계획되어 있고, 내년 4월까지 설계 성숙도를 높여 기술준비수준(TRL)을 향상시킬 예정이다.

AESA Radar development seems to be moving along

And this doesn't seem very relevant but it's interesting

Indonesian shares on KFX. Excerpted from MoD regulations on KF/IF-X development.  parts written in Indonesian are not important.

Problem from Indonesian side is related to attitude in our govt as some consider the  project is fruitless while we need to keep paying.  ON the academic side, we wish for more control which kinda absurd. However it difficult to exit anyway as we already poured funds into manufacturing facility for the fighter. We also already purchased some manufacturing equipment like autoclave and others.   The facility is ready and some part already used to help develop our local N-219 light aircraft.  There is also concern related to the number we would acquire that some consider 40-50 aircrafts just won't make break even points.

Would be interesting to see how much Power Aperture Product the KFX AESA would have.   To make use of 160-180km range of Meteor the design must feature at least 10 kW (like ECR-90) or more if the aperture area is less.

Hypothetical AESA with 1000 modules, 10 W power for each module and 25% duty cycle allows 260km Detection range for 50% probability and lock on/ tracking range (R90%) of 160 km.  Against 3 sqm target.

I have visted DX 2018 Korea.

That event concentrated on Army equipment, however, I could see updated feature of KF-X model and Korean Apache helicopter

Separated control surface for flap and aileron, extended fuselage can be seen

Indonesian economic woes are still affecting their share of the funding of the programme and they may seek to renegotiate the partnership deal and perhaps pause development.

The result of DPSR (Development Progress and Status Review)

Seems the configuration has been finalized, F414 being selected as engine.  Development continue which hopefully will yield prototype at 2020 and maiden flight at 2021.

News In Indonesian.
Pt-1
https://www.angkasareview.com/2018/12/06/positif-program-jet-tempur-kf-xif-x-berjalan-sesusai-rencana-bagian-1/

Pt-2
https://www.angkasareview.com/2018/12/08/ini-dia-konfigurasi-akhir-dan-detail-jet-tempur-kf-xif-x-bagian-2/

Pt-3
https://www.angkasareview.com/2018/12/10/tiga-skadron-jet-tempur-if-x-akan-memperkuat-sayap-tni-au-bagian-3/

In summary our KF/IFX have following features :

1.Boom refuelling system
2.Larger external fuel capacity for Indonesian variant (480L) compared to Korea (370L)
3.Drag chute (Korea does not need one tho but the jet will have it)
4.Total procurements of 120 aircraft (down from 130) Indonesia will have 48 aircraft.

So it's the same configuration for both SK and Indonesia. With block 2, some years ahead. 

48 airframes would basically become Indonesia's largest fighter purchase since Hawk.  the 48 airframes would make 3 squadrons.  looks formidable and in my view for special mission like counter cruise missile. Each squadron, assuming 15 aircrafts can be properly armed and airborne, can roughly handle salvo of 25 cruise missiles  with RCS of 0.01 sqm and speed of M 0.5.

Another one ...
He was my North, my South, my East and West,
My working week and my Sunday rest,
My noon, my midnight, my talk, my song;
I thought that love would last forever; I was wrong.
...
For nothing now can ever come to any good.
