Called an analogue of the Russian Su-75 Checkmate fighter, the South Korean KF-21 for the first time reached supersonic speed

South Korea continues to work on the creation of the latest KF-21 Boramae fighter, named as an analogue and competitor of the Russian Su-75 Checkmate fighter. To date, developers from the aircraft manufacturer KAI (Korean Aerospace Industries) are at the stage of flight tests, which involve three prototypes.

First flown in late July 2022, the KF-21 Boramae reached supersonic speed for the first time during a test flight on January 17, 2023. According to the Defense Procurement Program Administration (DAPA), achieving supersonic speed by the prototype means the completion of one of the key stages of testing. However, it is planned to complete the tests by February 2026, in total, six prototypes will be involved in them.

The tests of the aircraft, like the previous ones, took place at the factory airfield of the KAI (Korean Aerospace Industries) Corporation Sacheon in the city of Jinju. The first prototype of the fighter, which took off into the sky, spent 56 minutes in the air, reaching a speed of Mach 1 or 1224 km / h at an altitude of 12 meters.

The South Korean fighter KF-21 Boramae belongs to the 4++ generation. With a maximum takeoff weight of 25 kg, it can carry 600 kg of payload on 7700 suspension points. It is stated that the fighter will receive a radar with AFAR and will be produced in both single and double versions. To date, it is positioned as an analogue and competitor of the fifth-generation single-engine fighter Su-10 Checkmate being developed in Russia.

Although it is stated that work on the KF-21 started in 2016, it was first announced back in 2001, and Indonesia joined the program in 2010. It is planned that by the beginning of the 2030s, the Republic of Korea Air Force will receive about 120 KF-21 Boramae fighters. The new fighters will replace the outdated F-4 Phantom II and F-5 Freedom Fighter/Tiger II.

What does called analogue mean? There is no Su75! And during the time they showed the layout, they didn’t even make a prototype.

Called an analogue of the Russian Su-75 Checkmate fighter

Absolutely true, an existing thing cannot be an "analogue" of a non-existent one. The South Korean plane is already there and flying. There is no "chess fighter" and, most likely, there will not be.

Which of the journalists would at least once answer where they get their stupid headlines from.

[Ilgizl]

journalists are one of the oldest professions here, you need to keep a scent and scribble killer things so that there is a demand for an article for dough.

You are confusing a journalist with a propagandist or "alternative", a journalist does not have the freedom to invent, but has an obligation to provide objective and verified information. Sometimes journalists write to order, but then they cease to be journalists. A real journalist lives on reputation, on the trust of publications, readers, which attracts advertising, and so on.

Everything for the sake of the Ministry of Industry and Trade. Manturov failed in everything he undertook, especially in the aircraft industry - all deadlines, all programs, all means ... And even having received (lo and behold!) a scolding from Putin (as possible so on the untouchables), only thundered louder in the timpani of self-praise.
This is not fixable.
But we will not leave our own.

More curious - by whom named?

Today it is positioned as an analogue and competitor

Who exactly positioned?

[Sniper]

he is a competitor to our drawing .. on a piece of drawing paper ..

[blackice]

But is the SU-75 declared as a 4++ generation aircraft?
As far as I remember, they called him the 5th generation.

[Rusticolus]

To date, it is positioned as an analogue and competitor of the fifth-generation single-engine fighter Su-75 Checkmate being developed in Russia.

By whom is it considered? UAC leadership? How can flight prototypes compete with a full-sized mock-up of sticks and papier-mâché?

What experiments are carried out on this layout?
The first takeoff of this dummy is promised only next year. And then for sure they will transfer / shift to the right.
Years of sodium.
Journalists for such game and fables should be flogged publicly with rods. And drive three necks out of the profession.

[Leader_Barmaleev]

I'm wildly sorry, but these planes are not comparable at all - chess is single-engine, KF-21 Boramae is twin-engine. If someone considers this difference unprincipled, then he is deeply mistaken. but the main thing is that the KF-21 Boramae is already FLYING, but there is simply no chess.

[IVZ]

In my opinion, just a provocative and mocking article.

[Leader_Barmaleev]

I had exactly the same opinion - they just got these eternal analogues and piece copies for parades. But most of all, it infuriates when some mythical "development in the initial stage" is given out as a victory and a breakthrough and bravura reports are written. Manilov would have strangled himself with envy.

So at the most important "analogue" does not get off the tongue. Infected to see young hack writers.

[Andrey Stavropolsky]

4 ++ we have Su-35, all other thoughts are garbage.

[UAZ 452]

How we love to comfort ourselves! A potential enemy has a new weapon, but we have an analogue! And it doesn't matter that we have it in the form of cartoons and a layout, probably made in the workshops of Mosfilm.

[IVZ]

Well no. You didn’t understand, this is “they” an analogue and competitor to our product. And this is not a consolation, but either a mockery, or I don’t understand what.

[Maks1995]

IMHO what a mismatch
Su-75 - the concept of a single-engine aircraft

here is clearly a twin-engine aircraft. those. reduced analogue of F22 and SU 57

[ALARI]

Who is whose counterpart? The author express himself more clearly, do not mislead people, and some will wait and demand application this year.

[Green]

The Su 75 didn’t even raise the nose stance on takeoff on its own, so who and whose analogue is another question.

[km-21]

Polikarpov, Tupolev, Lavochkin, Ilyushin, Yakovlev, Mikoyan and Gurevich... During the Great Patriotic War, the Soviet aircraft industry produced dozens of concepts, many of which went into production. And today's Russia, in fact, flies on old Soviet developments and does not have time to look around at competitors flying far ahead.

Joseph Vissarionovich, come and help! Save and save Russia!

Joseph Vissarionovich, come and help! Save and save Russia!
Do you propose to revive the "sharashki" ?!
Support!
In wartime, a very effective tool that is stupid not to use.
And honors and recognition .. then. Necessarily. After Victory!

Aren't you afraid that those who convinced you to lie on the couch and "everything goes according to plan" pro ... love war, and their winners won't even hire you? Just turn it into garden compost?
Look at the pace of development of the USSR in the pre- and post-war years. Look at how the country worked during the Second World War. Look how Stalin's people's commissars and factory directors ruined their health and died young. But the Army was provided and the Victory was won.
At the machine!
And you are afraid of the machine, it turns out ... But Comrade Stalin had correctional institutions for such - such institutes of labor education. I am sure that Deripaska and Manturov would have made good lumberjacks, masons, or even (maybe) a turner in a sharashka.

competitor of the Russian fighter Su-75 Checkmate
Too shy to ask...
Where?
In the sky or in the market?..

[rocket757]

Called an analogue of the Russian Su-75 Checkmate fighter, the South Korean KF-21 for the first time reached supersonic speed

. It is clear that they are doing it ... and also, the great aircraft building power ... it looks like it.

[Romanenko]

Ours, unfortunately, so far only flies on paper.
And at the front, oh, how it could come in handy.
The result is not a Korean analogue and competitor to ours, but somehow the other way around.
It's a shame ...

[Normann]

I hesitate to ask, why is he at the front at the moment? Are there any more advanced machines in Ukraine that our aircraft, which are in service, cannot cope with?

[evgen1221]

Uh, I'm sorry. I see a Korean plane flying. And where is its analogue, which is 75?

[Georgy Sviridov_2]

A strange analogue, if the Su-75 is positioned as 5, and the Koreans are theirs as 4 ++. Then he is a competitor and analogue rather than the MiG-35.

[voyaka uh]

It is strange that the Koreans did not make internal compartments for weapons.
At least small ones.
To make a new plane - so the 5th generation.

[Hindu]

Called an analogue of the Lada Super Besta-Vesta (scheduled for release in 2035), the E-class Mercedes went on sale.
It is immediately clear that in many respects it is, of course, inferior to Lada, but what is, as they say. Until 2035, we will have to be content with this.

Did everyone notice how we became aware of how many types of tests there are? Bench, laboratory, running, state and other?
Because the bravura news is all about the next stage of the next stage.
Have seen the finished product before. Plots in the program "Time".
Now it's all a sample, a prototype, a test model...
Vigorous activity. True, there is no sense in this. But, that is...

[Atlant-1164]

important to write. and "People" and so "grabs".

[Mobik]

Yes... yes... the hamsters in the comments are indignant, but everything went wrong with the Koreans, and our chess one is only in the layout. But nothing that the program was started in 2001, and the first take-off was only in 22 ... and 75 was announced only in 21. The fact that the Koreans flew only 21 years after the start of the program is cool, not like the losers of the Russians, who, 2 years after the announcement, do not have hundreds of the latest fighters.

[Introvert]

Do the Koreans know that they are making a competitor to Konya? Or is it sprats of pen and paper again giving out fantasies for reality?
