I think @Indos can explained it more detail.
capability. put 
(or another) armament to IFX ?
Anything that KFX could cary, IFX could cary them too, isn't it?I think @Indos can explained it more detail.
Imho, both dumb bomb and ffar are considered dumb and organic armament, tho not much complicated system and within
Hence, for guided missile its a complex system and need this and that thing to do.
WDYT, is there any chance

Dunno mann, i still worry 'bout
permission, etc. 
made arsenal on inventory to use in IF-X
Yes, that's why I propose that we start with guidance kits for FFAR. Heck, you can imagine that we'll be able to develop a guidance kit for R-HAN 122 based on those kits.Imho, both dumb bomb and ffar are considered dumb and organic armament, tho not much complicated system and within
Start small but sure. If we're still don't have the capability to design and develop a guided missile from scratch, while we already have the capability to produce "dumb rockets", it should be a no-brainer what we can and must do to achieve that capability within a reasonable amount of time.

The design of KF21/IFX is based on C 103 that is designed by ADD Korea and Indonesian Aerospace+Institute Technology Bandung.
C 103 design ( there you can see the year of 2012), before KAI and LM comes to the program in 2015

Final design C 109 is just a refinement of C 103 design.

Then detail design will be work on after basic design is made, detail design needs many design engineers, this is why as of July 2019, there were 114 Indonesian engineers in KAI
"As of July, 114 Indonesian engineers were sent to South Korea to work with Korea Aerospace Industries Co. (KAI), the country's sole aircraft manufacturer, to design and make a prototype of the fighter, according to a DAPA official."

SEOUL, Oct. 7 (Yonhap) -- Indonesia is in arrears on its payment obligations for a joint p...en.yna.co.kr
Honestly, the cooperation in engineering development is not effected too much despite late payment and renegotiation and we see 116 Indonesian engineers were still in Korea until May 2020 where CDR meeting in 2019 September (completion of detail design).
What I know for 2021 target is to catch up with KAI engineering, particularly in production and testing. Indonesia Aerospace do making some parts for prototype 1,2, and 6 but we dont contribute in assembling and system integration of first and second prototype. Despite so, 30 engineers have been in Korea now as in late August they have flown to Korea, 100 will be in Korea in the end of 2021 inshaAllah.

ADEX 2019: Indonesia committed to KF-X project despite fiscal concerns

More than 100 engineers from Indonesian aerospace company PT Dirgantara (PTDI) remain involved in the project with South Korea to develop the next-generation Korean Fighter eXperimental (KF-X) fighter aircraft despite growing concern about the Southeast Asian country's financial involvement in the programme.
Industry officials told Jane's at the 2019 Seoul International Aerospace and Defense Exhibition (ADEX) that ties between PTDI at Korea Aerospace Industries (KAI), which is leading the KF-X programme, remain strong even if the South Korean and Indonesian governments have yet to reach an agreement on how - and how much - Jakarta will pay towards the development project.
"We have 114 engineers working on the KF-X in Korea," said one official from KAI. "They are mainly working on the design of the aircraft but also on manufacturing processes." PTDI told Jane's that its engineers' involvement in the programme is intended to support the company's long-term development and its ability to apply acquired skills across a range of platforms.
Industry officials would not comment directly on government-level talks intended to enable Jakarta to fund its involvement in the programme, which it refers to as IF-X. These talks started in October 2018 after Indonesia said that due to a lack of funding it wanted to renegotiate the financial arrangements that were agreed in 2015. Renegotiations were initially expected to be concluded within 12 months but have yet to be finalised.
Under the original KF-X finance agreement Indonesia is committed to pay for 20% of the total development costs of the aircraft, which are estimated at about USD8 billion. The South Korean government is committed to pay for 60% of costs, with KAI covering the remaining 20%.

I heard they will use boom system like korean in the end.KF21 and IFX will be in no different, except some like IFX may use parachute like Su 30 and different air-refueling system.
KF 21 will use US armament like JDAM while BVR and WVR missiles are European ( Meteor for BVR and IRIS-T for WVR)

KFX/IFX Fighter Aircraft development reaches 20 percent

Jakarta (ANTARA News) - The development of fighter aircraft 4.5 generation, Korean Fighter Xperiment/Indonesia Fighter Xperiment (KFX/IFX) under cooperation of Indonesia and South Korea which was established since 2011, has been reaching 20 percent.
"Until now the development process has been reaching 20 percent. There are three stages we need to pass, namely technology development, EMD (engineering and manufacturing development), and prototyping," Director of Technology and Development of PT Dirgantara Indonesia (PT DI) Air Marshal Gita Amperiawan said at a press conference here on Thursday.
According to him, after the G to G cooperation project has been running for seven years, the preliminary design review phase has completed to ensure the configuration of the KFX/IFX fighter aircraft has met the operational requirements of the Indonesian Air Force (TNI AU) and the Republic of Korea Air Force (ROKAF).
"Today we are socializing to all stakeholders, including the Ministry of Defense, Coordinating Ministry for Politics of Law and Human Rights about the development progress of the engineering manufacturing development phase," Gita said.
He further said, after the preliminary design was completed, the two countries will develop the prototype of the fighter.
This fighter aircraft is expected to be mass produced in 2026 after passing flight tests and certifications.
"We have passed the technology development phase and EMP. The details of the design are expected to complete around July or August 2019, and we will begin prototyping, testing and certification processes," he noted.
Gita added that the Indonesian and South Korean governments accommodate common requirements that the prototyping should accommodate the interests of the Indonesian Air Force.
There will be 168 units of aircraft to be produced. South Korea will receive 120 aircraft while Indonesia will get 48 units.
"We contribute 20 percent in each phase according to the agreement," he said.
At the same occasion, Chairman of PT DI`s KFX / IFX Program Heri Yansyah said the Indonesian aircraft industry PT Dirgantara Indonesia (PT DI) and Korea Aerospace Industries (KAI) are just system integrators in the development of KFX / IFX aircraft.
"So, all components will be produced by other parties including engines and avionics. The navigation is produced by other parties that will be integrated into this aircraft. We also have plans on how aircraft technology can be built by Indonesia`s local industries, such as PT Pindad," he said.
According to Heri, Pindad, which is the Indonesian state-owned enterprise specialization in military and commercial products, could make weapon system for this generation 4.5 fighter.
"The weapons can be produced by Pindad. We also build technologies, such as data links, weapon integration, and radar. These are our works that we call strategic investment. We will figure out how to produce fighter aircraft in the country because it relates to our independence," Heri said.
The KFX/IFX fighter is a generation 4.5 of semi-stealth multi-role aircraft developed by Indonesia and South Korea. This fighter aircraft is designed to replace ROFKA and Indonesian Air Force`s fighter jets.
Some of the advantages of KFX / IFX fighter include semi-stealth, and have semi conformal missile launchers, advanced avionics and air refueling.
In a memorandum of understanding signed by the two countries, Indonesia covers 20 percent the total cost of the fighter development program, while South Korea bears 80 percent of it.

They can hire as many foreign researchers as they want, but as long as the whole state's R&D budget still remains as low as it always been, we won't get anywhere far.
Well the money is kinda ngepres nowadays
