Watch out, the Chinese are spreading false information in kf-21 YouTube videos. It is written and distributed by Chinese people. You can see how scared the Chinese are about kf-21.

All core technologies of kf21 were developed in-house. In other words, in the same way as Rafale, Gripen, and Typhoon, all avionics equipment and fuselage design and manufacturing except subsystems and engines were made with Korean technology. In particular, major equipment such as AESA radar, eo tgp, core technology rejected by the US Congress, and rf jammer all have their own IP. In addition, avionics systems, avionics, integrated display devices, integrated electronic warfare systems, and k-link for Link 16 were independently developed.

The main development equipment is as follows. And it contains its own IP

1.AESA radar -Hanwha,, ADD (KOREA),

2.IRST -Hanwha, kai(KOREA),

3.Eotgp -Hanwha, kai,(KOREA)

4.RF-jammer-LIG Nex1(KOREA),

5.EWC-LIG Nex1(KOREA),

6.PWR-LIG Nex1(KOREA),

7.CMDS -LIG Nex1(KOREA),

8.MISSON computer-KAI,ADD(KOREA)

9.DIGITALCOCKPIT, Hanwha,, ADD (KOREA),

10. Ge Engine -Hanwha License (KOREA)

11. Avionics control system- kai(korea)

12. brake system -KAI(KOREA),

13.K-LINK communication system-Hanwha,, ADD (KOREA),

14 aircraft fuselage - KAI(korea),

15 Aircraft Wings-KAI(KOREA)

Currently, the domestic localization rate is 65%, which is the ratio of the total number of parts converted to price. That is, in kf21 we set the cost of 300,000 parts to 100% and localize 65% of the parts cost. However, considering that the engine cost of a twin-engine fighter is 30%, the core equipment excluding the engine was independently developed in Korea. And other sub-equipment, such as the rest of the seats, are imported from other countries. However, this is the same development method as Rafale and Typhoon Gripen, and it is very good in terms of cost-effectiveness. This is because independent development of subsystems is not a matter of technical difficulty, but is very poor in cost-effectiveness. Above all, China's J-20 relies on foreign countries such as Israel, the UK, and Russia for all important core parts such as engines and AESA radars. This shows much inferior technical independence to Korea's KF-21. Of course, the Chinese still claim to be their technology. It is a pirated copy.

小心，中国人在kf-21 YouTube视频中传播虚假信息。它是由中国人编写和分发的。你可以看到中国人对kf-21有多害怕。

kf21的所有核心技术都是内部开发的。也就是说，和“阵风”、“鹰狮”、“台风”一样，除了子系统和发动机之外，所有的航空电子设备和机身设计和制造都是用韩国技术制造的。特别是AESA雷达、eo tgp、被美国国会否决的核心技术、射频干扰机等主要设备都有自己的IP。自主研发了航电系统、航电设备、综合显示设备、综合电子战系统、第16链k链等。

主要研制设备如下。它包含自己的IP

1.AESA雷达-韩华，ADD(韩国)

2.IRST韩华,凯(韩国),

3.Eotgp韩华,凯(韩国)

4.RF-jammer-LIG Nex1(韩国),

5.EWC-LIG Nex1(韩国),

6.PWR-LIG Nex1(韩国),

7.CMDS闲逛Nex1(韩国),

8.美声computer-KAI,添加(韩国)

9.数字座舱，韩华，ADD(韩国)

10. Ge Engine -韩华许可证(韩国)

11. 航空电子控制系统。kai(韩国)

12. 制动系统凯(韩国),

13.K-LINK通信系统

14 .飞机机身——KAI(韩国)，

15架飞机Wings-KAI(韩国)

目前，国产化率为65%，这是零部件总数量与价格的比率。即在kf21中，我们将30万件的成本设定为100%，并将65%的零部件成本国产化。但是考虑到双发战斗机的发动机费用为30%，除发动机以外的核心装备都是韩国自主开发的。其他的附属设备，如其余的座椅，都是从其他国家进口的。但是，这和“阵风”、“鹰狮”的开发方法是一样的，在性价比上是非常好的。这是因为子系统的独立开发不是一个技术困难的问题，而是在成本效益方面非常差的问题。最重要的是，中国的歼-20在发动机和AESA雷达等所有重要核心部件上都依赖于以色列、英国和俄罗斯等国家。这与韩国的KF-21相比，技术独立性差很多。当然，中国人仍然声称自己的技术是他们的。这是盗版的。

以上是KF21在油管的回复评论..之前有中国网友评论如下.才引发韩国网友回复.大意是说韩国KF21是组装货.

KF21:

1. The nose, designed by Sweden-Saab,

2. Airframe, American - Lockheed Martin design,

3. Canopy, USA - Texstars,

4. Ejection Seat, UK - Martin Baker,

5. Airborne Instruments, USA - Curtis Wright,

6. Brake system, Spain-CESA,

7. Environmental Control System, United States-United Technologies,

8. Engine, USA - General Electric F414-GE-400K,

9. Wheel Brake/Flight Display/Fire Control and Rescue System, UK-Mejit,

10. Missile Launcher/Communication Antenna/Oxygen Supply System, UK-Cohamy

11. AESA radar Israel's ELTA, directly used TR components of ELM-2052

12. Aiming pod, radio frequency jammer, CNI IRST is Lockheed Martin

有没有懂行的指教下,KF21国产化率这么高了吗?
