Correct - the Sth Koreans had Russian support (Almaz-Antey) - it's essentially a variant of the Russian 9M96 missile used in the S-400 system:

Having revisited the thread, this can't be further from truth. KM-SAM basic system design was done by AA as noted above, but the effector design is so noticeably different I'm not sure how you could call it a variant of the 9M96 missile used in S-400.

It is said that was developed by the Agency for Defense Development (ADD) with technical support from Almaz-Antey and Fakel, based on technology from the 9M96 missile used on S-350E and S-400 missile systems. This allows it to be both different and similar at the same time and depending upon the degree of similarity could be accurately declared a variant of.

Well, the problem is, it isn't a variant. The design differs too much to be called such. You could cite Global Security all you want but the differences of their designs, which is just out there for you to simply see, indicates otherwise. Else, it's just your definition of 'variant'.

How about listing with evidence/references some of the differences as I don't have the specifics on either...

What I do know is that it is reported in multiple locations (see below for a few examples) that the S-350 Vityaz and KM-SAM/Cheolmae 2/Chung Koong are related or at the very least, that the latter was developed using technology from the former.

As with anything, it is on someone who claims something exists to prove that, not someone doubting such existence. As in this case, you are claiming that there's a concrete connection between KM-SAM effector design and 9M96E that it could be called a variant, and I'm telling that's not true. Then it's not on me to prove that such connection doesn't exist.

I have never doubted this. I've also exclusively said that there's clear AA involvement in KM-SAM development. They provided basic technological basis for the SAM system, especially the radar. But KM-SAM is still an independent product. Korea for example developed its own X-band space-feeder PESA demonstrator prior to developing the KM-SAM radar, so it's also not the case that KM-SAM was entirely designed by AA, as some other forum members have claimed on this thread.

Most importantly, what I'm explicitly disputing is your claim that 'KM-SAM effector is the variant of 9M96', which, as I've said countless times, is outright wrong.

Although the SAM system was co-developed with Russia, the effector itself was developed by ADD and LIG Nex1, and input from Russia was limited on this front. The most notable Russian input was the cold-launch technique and the ACS side thruster technology, but as you could very easily notice, the ACS design is very different from that of 9M96 side thruster. They also differ in their warhead design, KM-SAM effector is guided by a Korean Ku-band seeker and the ACS and warhead position itself is also different compared to that of 9M96E. It also doesn't have cannards, indicating very different aerodynamics and handling characteristics. KM-SAM block-I terminal guidance solely relies on tail-fin and side ACS. The booster is also proportionately shorter on KM-SAM compared to 9M96E. When all these clear evidences can't convince you, LIG Nex1's own magazine Gndeun also mentions the same, that the SAM complex was developed with Almaz Antey but the missile was developed by ADD and them as their own design.

There's already a precedent in Korean SAM design (K-31 Pegasus) where the SAM system was co-developed with a foreign company (Thales) but the effector missile was an indigenous design (Crotale and Pegasus missile designs are very noticably different similar to 9M96E and KM-SAM).

The writing is basically on the wall and it's so easy to notice them. It's important to understand that it doesn't really matter how many media outlets claim the same thing, when none of them have a concrete first-hand source to support what's written in the article. If anything, a lot of those "report" that you've cited just parrot what they've found elsewhere without much consideration, which is especially more true when it comes to South Korean weaponery, of which credible information in English is very obscure.

I am/was only repeating what is reported. I also therefore assert that if the Korean weapon uses technology from the Russian it could be argued to be a variant of. Now one might naturally differ as to what % commonality constitutes a variant vs a new product. For example, if a missile had the same warhead, engine, guidance and basically internals but perhaps different external features such as fins and body would that be deemed a variant of or a new weapon?

As to my asking you to provide evidence, it was in reaction to your simply saying I was wrong but not explaining why. I was simply trying to illicit more detailed information rather than just saying I was wrong. I thank you for the information you have now shared.

Thanks for the new thread, but I think we could keep several of these topics in a single thread, maybe it could be named "ROK Air and Missile Defence systems" or something along the lines.

There's already L-SAM thread where some matters, mostly about L-SAM, has been handled and on top of that there's the S-350 thread in which quite a few KM-SAM related discussions took place. I think we can merge all of these into one.
 
@GTX sometimes you have to admit you were mistaken.

For something to be a variant of something it has to have some large scale commonality of components and design. The PL-9 AAM is in part derived from the Python-3 clone PL-8, but you couldn't really call it a variant of it, nor would anyone call the the Z-10 a variant of the Ka-50 despite Kamov assisting on the design of the latter and some generic family resemblance.

So on this point I'd have to say I don't think KL-SAM can be described as a variant. And therefore we probably need to tidy up this topic.

9M96 has two sets of side thrusters. One is located under the missile’s front wings, used for initial steering after the missile’s cold launch. The other set is a ring-shaped nozzle in the middle of the missile body, used for the terminal phase.
But M-SAM seems to have only one set of side thrusters. Is its usage method similar to the PAC-3? The one set is used during launch and terminal phase.

what is the difference between their warheads?
some korean websites have mention their differences(both directional warheads, but the details are different?), but there seems to be no data to check. I tried searching, but no results either.

This is Chun-goong block 1 effector side thruster design. As you've guessed, it's a SIE similar to PAC-3 side thrusters and is used for both missile attitude control after launch and during terminal phase.

Chun-goong block 2 has two separate side thrusters, of which the terminal phase side thruster being what ADD calls a "Nozzle Closure Separation Device". Post-launch ACS is very similar to what was already being used in block 1. The new DCS is more similar to 9M96 in terms of how it is structured internally.

So overall, quite a difference for the side thruster designs for both the block 1 and block 2 effectors.

Chun-goong uses kinetic energy rod warhead, whereas to my knowledge, 9M96 variants doesn't.

I don't know what the original source material that you have translated is, but that is false info. L-SAM AAM will have its DCS side thruster placed just in front of the main propellant behind the guidance section. What it doesn't have is the post-launch ACS, since it is hot-launched unlike Chungung

As for the side thrusters of L-SAM AAM, I initially agreed with you, but recently some koreans went to the ADEX 2023 site to inquire and only then did they get this result. and korea military magazines also have the same mention (they are also at the ADEX site).
But I will ask them to check it

Yes I could always be wrong as well, but you should also keep in mind that most of those Korean military magazines are not as credible as their English counterparts. Also, you could still identify the DCS side thruster nozzles on the mockup presented in LIG Nex1 booth.

Though yes, if you have Korean friends, please inquire them as well.

I already confirmed with korean friend, the officials at ADEX confirmed this.
But did not explain the reason. He also gave me relevant pictures, you can see the difference between the "nozzles".
He also say: There are(L-SAM AAM) only 3 patches in that square shape, and if there were 4 patches the spacing would be closer; not enough space in the missile fuselage to place the side thruster.

I see. If those information comes from LIG Nex1 personnel first-hand, then you must be right. I've mistaken those patches for a thruster nozzle, since they are located where the thruster nozzles were in the initial study model.

I trust him 100% because he often attends exhibitions in person and obtains book/brochure distributed onsite. There is a lot of "pay to win" in the KR/JP field(their book and journal are more valuable, containing more info).
Many military media often make mistakes in these fields, for example Jane's thought JP DDG-173 was BL 9 (the latest Jane's says initial BL for DDG173 was 3), but if you read Japanese magazines you'd know right answer it's BL 5.2.
For KR field, Jane's claimed KDX3 uses SQQ89 and SQS53C.

Their domestic publications are more credible in comparison. Because for some things, the real truth may never be found from official sources.

South Korea completes development of long-range SAM system

South Korea outlines development of enhanced air-defence systems

South Korea's Defense Acquisition Program Administration (DAPA) has announced a plan to develop enhanced air-defence systems to counter missile threats from North Korea.

In a press release on 29 May, DAPA said that it will initiate the development of long-range surface-to-air missile II (L-SAM II) system and medium-range surface-to-air missile Block III (M-SAM III) system in 2024.

Some errors in the article, it mentions that the development of L-SAM II and M-SAM III will continue until 2032 and 2034 respectively, but those are the schedule for the full-service entry of all planned batteries, not the conclusion of development phase. Development will end much earlier.

Find it mildly funny that vehicles look quite similar to their northern counterparts.

Best Korea going for the closest visual match for obvious deterrence was always the thing, but it's surprising how South seems to be doing the exact same symmetrical thing.
