You are Correct. The kf-21 block 1 and block 2 fighters are 4.5th generation fighters built to replace the older f-4 and f-5. The kf-21 is not a fighter designed to meet the demand for high-and-class performance fighters until block 2. Rather, it is a fighter made to meet the demand for low- to middle-class fighter jets. And it is more meaningful to secure a platform to freely test domestic air-to-air missiles, air-to-ground missiles, and air-to-ship missiles. Ultimately, the goal is to develop 5th generation fighter jets in the most cost-effective and safe way and to lay the foundation for the conceptual research of 6th generation fighter jets. That's why the kf-21 has a stealth shape and has plenty of room for internal armed payloads, even though it's not a stealth fighter yet. So, Korean engineers don't compare the kf-21 block 1 and block 2 to the 5th generation stealth fighter j-20 in China. If they're going to compare it, it makes sense to compare it to China's j-16, and the U.S.'s f-16. In fact, the fighter jet that the Korean government demanded from the Korean engineers is a Korean version of the enlarged Super f-16 that has room for evolution into stealth aircraft in the future. So it's not appropriate to compare kf-21 fighters to 5th generation fighters until kf-21 block 3 comes out. Because in the first place, we Koreans are not already expecting the performance of the 5th generation fighter from the kf-21 block1 and block2. We are expecting the most cost effective performance of the 5th generation fighter from the kf-21 block3 in the far future, such as.. 5th generation verson of f-16? That's what the f-35 fighter should have been but failed.
Korean developers do not consider this aircraft to be a 5th generation aircraft. It wasn't planned that way from the beginning. This aircraft was created with the goal of achieving top performance among the 4th generation aircraft. Nevertheless, Korean paint companies have already created high-performance stealth paints. In other words, Korea has made this aircraft a 4th generation aircraft, but has already made technical preparations to move directly to the next stage. Korea is already considering the 5th and 6th generations and is solving technical problems one by one. For example, stealth paint, close-infrared anti-aircraft missile defense (DIRCM), and Manned-Unmanned Teaming (MUM-T) are already being developed or are in the process of being completed. Of course, for the time being, the short-term goal is to mass-produce this early model to replace the 4th generation fighters F-5, KF-16 and KF-15.
There is no doubt that the kf21 is the world's number one fifth-generation fighter, completely surpassing the f22 and f35. After all, it is the most powerful country in the universe. All Chinese culture and history are copied from South Korea.

@@yongkim5826 The techno of aircraft covering will greatly affect the stealth performance of fighters,we can see specially treated polygonal skin on J20，but KF21 just has common covering like other 4th fighters,which may increases the chance of the plane being detected by radar.
South Koreans are intelligent and practical. They know how to efficiently use their limited resources without wasting them. Instead of rushing to develop a 5th generation fighter jet on their own, South Korea collaborated with Lockheed Martin from the United States to create a long-term roadmap that considers future upgrades. This approach is highly effective in securing reliability and reducing costs through the gradual advancement of South Korean technological capabilities. It's similar to the development case of another South Korean fighter jet, the FA-50. The FA-50, having gained high reliability through decades of operation and positioned in a relatively less competitive category, is currently being sold worldwide. I'm confident that the KF-21 will succeed in niche markets through effective upgrades in the future, similar to the case of the FA-50.
The problem is that u have no clue about geopolitics and how the world works. China is part of the global south that has been looted and destroyed by west, and instead of following the puppet state via of south korea to west, China is a sovereign country, and that means that west and USA will sanction and dont give that aircraft parts.

KF 21 is just the mix of various technologies borrowed from different countries, especially the engine is from America. It is ridiculous to compare with J20. They are of different classes of plane. It is ashamed to put two planes into one classification. KF 21 is not Stealth plane. Don't exaggerate too much.
Interestingly, people who witnessed J20's under-burned jet spin-off in China posted a video on social media, and suddenly it was all deleted and all the people who posted or wrote the video suddenly disappeared.
KF-21 will be modified into stealth fighter with internal bay and will be called other model. It’s because using USA technology transfer and Indonesia will not has the stealth version
As korean, we still have long way to go. KF21 is basically replacement for F-5 and KF-16 , but can be upgraded to stealth fighter - but long long way to go...currently no match for J20 , so we have F35s.
@@sougayilangfishingtackles9312 Because the F35 purchased by Korea needs to apply for a password from the US military every time it is turned on. And maintenance cannot be performed in Korea.
In December 1994, the South Korean Army took back peacetime command authority from the U.S. Forces in South Korea, but wartime command authority was still held by the U.S. Command. The peacetime and wartime command rights of the Air Force and Navy are still controlled by the US Command.
Objectively speaking, with South Korea's size, being able to successfully assemble the K21 under the guidance of Lockheed Martin is an achievement worth boasting about.
@goodjob3314 Russia does not have a canard design. The last Russian-designed fighter jet was the J-11. Starting from the J-10, they are all redesigned. It is necessary to design not only the appearance of the fighter jet, but also a more complex flight control system.
@goodjob3314J20 has replaced the engine early. You need to read more news. In addition, compared with being invisible, the engine problem is just a small matter. The Russian s57 has the best engine, but it can‘t appear on the front line of the war now because of poor stealth. External ammunition and direct air ducts are fatal to stealth damage, and so is kf.
KF21 will win because it will be built in SK. Most things built in SK will be better than anywhere else in the entire world but America. And just by the naming you can tell KF21 is greater than J20 but lesser than F22. I have full faith in SK.
J20 is a fighter that is weak against dogfight vs KF21 is No. 1 in the world for dogfight. Because long-range air-to-air missiles with a range of more than 25 kilometers, Air-to-air missiles cannot shoot down enemy aircraft because the radar's waves are bent by gravity. Thus, the dogfight champion's KF21 can shoot down all J20 🤣🤣
The J-20 is more of a Rafale fighter than a stealth aircraft. If you look at the airplane building, it is no match for the F-22 The ability of the F-22 to fly like a leaf is beyond
@@felipesun4679 It seems like China is very proud of having built a wind tunnel laboratory! Haha, that doesn't even require any special skills. Of course, it exists in Korea too.
Looks like KF21 will have J20 for breakfast with better maneuverability and higher performance all around. Most importantly KF21 won’t break down like J20 will. Just admit S Koreans make better quality products than China. 😂
Why partner with Indonesia? If the KF21 is so great, why don't other countries with their own technology join in? Take our neighboring country, Japan, for example. Japan is already co-developing fighter jets with the UK and Italy. Frankly, it's obvious to everyone that there is a big gap. Which would you rather partner with, Indonesia or Europe?
In India, the SU-30 discovered and tracked the Chinese J-20 using radar. Therefore, the J-20's stealth function is being questioned. Several technical issues raise questions as to whether that fighter jet is truly equipped at the 5th generation level.

The kf21 doesn't even have a built-in magazine, so it's not a fifth-generation fighter at all.
You are Correct.
The kf-21 block 1 and block 2 fighters are 4.5th generation fighters built to replace the older f-4 and f-5.
The kf-21 is not a fighter designed to meet the demand for high-and-class performance fighters until block 2.
Rather, it is a fighter made to meet the demand for low- to middle-class fighter jets.
And it is more meaningful to secure a platform to freely test domestic air-to-air missiles, air-to-ground missiles, and air-to-ship missiles.
Ultimately, the goal is to develop 5th generation fighter jets in the most cost-effective and safe way and to lay the foundation for the conceptual research of 6th generation fighter jets.
That's why the kf-21 has a stealth shape and has plenty of room for internal armed payloads, even though it's not a stealth fighter yet.

问题1:KF-21是隐身战斗机（第五代战机）吗？
答:不是。KF-21战斗机虽然在设计上融合了隐身技术，具有一定的隐身潜力，但它并不具备完全的隐身能力。主要原因包括：
1. 缺乏内置弹舱：KF-21目前的设计没有内置弹舱，而是采用外挂和半埋式挂载武器，在腹部设置了4个半埋式的挂架，这在执行任务时会增加雷达反射面积，大大降低了隐身效果。2. 隐身材料和细节处理：在隐身材料上和中美俄有不小差距，在细节处理上也不如成熟的隐身战机，因此其隐身能力在实际作战中可能不如专业的五代机。3. 设计理念：KF-21的早期版本并没有将隐身性作为其主要设计目标，而是更注重速度和整体性能。对于内置弹舱这一特性，KF-21选择了暂时搁置，以便于更快地推出一款介于第四代和第五代之间的战斗机。综上所述，kf-21战机是韩国为尽快推出新一代战机而在设计和性能上妥协的产品，其整体性能上可圈可点但并不具备关键的隐身能力，面对五代机的超视距打击仍然处于绝对劣势。
问题二:KF-21战斗机是韩国自主研发的吗？
KF-21在设计上较多抄袭美军的F-22，关键技术部件上仍然依赖于外部供应，尤其是美国的技术，离自主生产仍然有很大一段距离:
1. 技术合作与引进：在KF-21的研发和市场化推广中，韩国采取了拿来主义和自力更生相结合的方式。关键系统如发动机、坦克炮、飞控软件等直接采购欧美先进成品，而弹药、车辆底盘、飞机零部件、航电设备等次要子系统则自主研发或引进技术国产化。2. 降低对美国的依赖：通过研发KF-21，韩国在一定程度上降低了对美国的依赖，拥有生产KF-X所需技术的63%，并在机载有源相控阵雷达、红外搜索与跟踪系统等多项核心技术上取得突破。3. 核心技术受制于人：尽管韩国在KF-21项目中取得了一定的自主研发成果，但包括发动机在内的一些核心技术仍然来自美国，这意味着韩国在KF-21的研制过程中，自主研发的成分相对较少，未来的量产也得受制于人。4.外形设计：KF-21的外形与美国F-22战斗机高度相似，采用双垂尾、双发布局，进气道位于机翼前缘延伸面下方，采用S型结构，主翼和水平尾翼采用小展弦比梯形翼面，机头采用隐身性较好的菱形设计。这种设计思路受到了美国军方的追捧。5.隐身特性：KF-21在设计上对F-22模仿的痕迹很重，表面上F-22所具备的隐身特性在KF-21上大都有所体现，包括边缘平行原理、保型天线、S型弯曲进气道、外倾垂尾等。机身表面覆盖隐身涂层，第一批次采用隐身涂料，后续量产型会换用瓦片状隐身蒙皮。

如果你想反驳，请提供依据，不要无脑乱叫，否则显得你很无知😆
KF 21 is just the mix of various technologies borrowed from different countries, especially the engine is from America. It is ridiculous to compare with J20. They are of different classes of plane.

In December 1994, the South Korean Army took back peacetime command authority from the U.S. Forces in South Korea, but wartime command authority was still held by the U.S. Command. The peacetime and wartime command rights of the Air Force and Navy are still controlled by the US Command.

@@夏丹青 Agree. Korea is actually doing much better than many countries that were industrialized decades earlier.
@goodjob3314 Russia does not have a canard design. The last Russian-designed fighter jet was the J-11. Starting from the J-10, they are all redesigned. It is necessary to design not only the appearance of the fighter jet, but also a more complex flight control system.
@goodjob3314J20 has replaced the engine early. You need to read more news. In addition, compared with being invisible, the engine problem is just a small matter. The Russian s57 has the best engine, but it can‘t appear on the front line of the war now because of poor stealth. External ammunition and direct air ducts are fatal to stealth damage, and so is kf.
