https://www.armyrecognition.com/china_chinese_army_missile_systems_vehicles/fd-2000_long_range_air_defense_missile_system_technical_data_sheet_specifications_pictures_video.html

Overall, the technology and performance level of the basic HQ-9 is between the Russian S-300PMU1/2. Due to the late development of the Hongqi-9 and the use of terminal active radar guidance, it should have more advanced computer software and hardware than the S-300PMU1, and the anti-jamming capability and human-machine interface should be better. However, the range and anti-tactical ballistic missile performance of the HQ-9 should not be as good as the S300PMU1/2.

H_min        = 5.0,  --minimum flight altitude                                   -- should be 14.0 (able to engage Skiming missiles alt 15m), 5m height not given by any document

Diam         = 340.0,                                                                      -- Must be 470.0 mm (Dekas 3D model is 460mm - almost as it should be. Strange is why Deka is intentionaly decreases Lua diameter to reduce missile drag, do the ED supervising team know about that?).

D_min        = 800.0, --minimum launch range                                 -- should be 5000.0 m (5km)

Mach_max     = 5,                                                                                       -- should be 4.2 M

H_min_t      = 10.0, --minimum target height                                        -- should be 25.0 m

ccm_k0       = 0.15,  -- susceptibility to bait by CHAFF                           -- should be slightly better than DCS LRS (DCS S-300PS ccm_k0 = 0.5, DCS Patriot ccm_k0 = 0.5) l would expect value ccm_k0       = 0.3

exhaust      = { 1, 1, 1, 0.5 },                                                                       -- should be { 1, 1, 1, 1.0 }, burning engine produces thick white smoke

SA_N_12_9M317 missile performance not according to public available data and other wrong Lua code values.

Some of my information sources:

https://en.wikipedia.org/wiki/Buk_missile_system

"Worldwide Equipment Guide (WEG) Update 2011"

The modernised version of the 3S90m is the 9K37M1-2 (or 9K317E) "Ezh", which carries the NATO reporting name "Grizzly" or SA-N-12 and the export designation "Shtil". It uses the new 9M317 missile.

M            = 685.0,                                                                     -- should be 715 kg

H_max        = 15000.0,                                                                -- should be 25000 (improvement)

Mach_max     = 4.5,                                                                    -- should be 3.6 (ALL three reported missile have higher max Mach and very short Minimum Engaging Range)

Life_Time    = 300.0,                                                                   -- should be max 120 sec, 80 sec is lifetime of DCS SA9M38M1 (SA-11) missile

Range_max    = 40000.0, -- по верхней границе                          -- should be 42000 (improvement)

exhaust      = { 1, 1, 1, 0.5 },                                                        -- should be { 1, 1, 1, 1.0 },

Hi @BIGNEWY , these values of Dekas missile parameters are not from some Lua datamine, but from game itself.
DCS World OpenBeta\CoreMods\aircraft\ChinaAssetPack\Entries\Tech\weapons.lua

I reported these missiles wrong at the January 5th this year - No answer.

Than I send at January 27th message to bumb it, (because in mean time, Dekas devs made missile parameters even Boosted) This time with answer from @uboats (high up on this page) "our engineer had no time to check it in jan yet.  will check it later" 😅

Than is send at April 18th detailed list of wrong things - No answer.

Than I Seems like Dekas devs dont want to even answer to my BUG reports OR FIX THE VALUES, so PLEASE can you do something with that? ED controls missile performance of 3rd parties, or do I not remember it correctly?
To me the scenario reminds me the situation with first release of Dekas SD-10/PL12 UFO missile which was at the end corrected under pressure from ED side. Deka simply dont want to make its missile under the law of ED code and make up its own parameters to match some unknown source perfrmonace.

sorry, our missile engineer was busy and i forgot this thread

param updated

Todays update:

  • Weapons. Fixed SA-N-12, HHQ-9 and HQ-16 params

Where??, Seems that somebody fixed it but only in his PC and forget to send it to ED:

Hello,

The "HQ7_LN_EO" unit otherwise known as the Electro-Optic version of the HQ7 launcher does not have the "vehicle" property like every other ground unit that is a vehicle in DCS, please add it for consistency and as to not cause issues with scripts.

Thanks !

Hi, @uboats .

HQ-7 LN Electro-Optics may no longer be under attack by AI helicopters.
It appears that the AI attacks only the regular HQ-7 and fails to recognize the HQ-7 LNE as an attack target.

Sorry, I don't speak English, so I use DeepL Translate. Well, I can speak Japanese.
