AIM-9X Block II Mod for BMS
-
@fegeleinn @drtbkj
Are you sure you want to transform AIM-9X, IRIS-T… in fox-3 missile with aircraft-to-missile data link and mid course update (in french LAM), device they do not have at all ?
Why the hell would you do such a mess ? -
@TOPOLO The real 9x Block II features datalink and lock-on-after-launch capability.
-
This is correct. The block II receives updates from the host radar for course corrections in the same way the AIM-120 does and locks ons after launch (in SLAVE mode). The missile is advertised to have greater kinematic range.

@TOPOLO
9X Block II is specifically updated to have LOAL and DL because USAF wanted to load those missiles on F-35 without decreasing the stealth factor by putting them on underwing stores.Also, from my testing farthest kill i can get kinematically is 15nm against a bomber at 40.000ft. for fighter size maneuvering targets at 15.000ft that range drops to 9nm (head-on) at best. So they are nowhere close to any ARH missile. They are just more reliable now.

If i remember correctly, Block III is supposed to use different fuel type to increase range and ground-handling safety but no idea how much is the improvement over the older blocks…

Good Day, All.
From this https://www.airforce-technology.com/projects/aim-9x-sidewinder-air-to-air-missile/?cf-view
You find this-“The AIM-9X Block II missile completed its first test firing in November 2008. Also known as AIM-9X-2, the missile is an upgraded variant with a lock-on-after-launch feature. AIM-9X Block II has a redesigned fuse and a unidirectional forward-quarter datalink. The datalink enables it to engage targets even beyond the visual range.”
We’re working on putting it in the OFM database. Putting it in as a standalone is easy, as Fegeleinn described. The next step is setting it up so you can have both the 9X and 9X-2 as individual entities. -

@fegeleinn @MaxWaldorf
this mod is amazing as well as this new update/implementation -
@drtbkj - don’t overlook that you will also need to find a way to cue it to JHMCS, and also that your helmet alignment is going to become just that much bigger a factor in being able to use it well…that goes for all -9X variants, really.

You do realize that he is not a BMS dev And that what you are talking about is obviously code related and not data ?
-
At least the mindset is good.
The point of the LoAL the make the AIM-9X a BVR missile at med-high alt against an incoming target. It is just a 99.9% theoretical capability that if you have a data link connection or DAS track, you can launch backwards. (Time lag? RoE?)
But. If you have data link or DAS and you sit in an F-35 nobody every shall be on your tail in the range of AIM-9X launching backwards… while you had not been killed with a missile launch…

Hi, Stevie. All true. I tested it yesterday. I’m still testing to learn how to implement. I turned labels on for testing and did notice datalink and tracking messages like you see with an AIM-120D.
Also, All, I should point out that it’s true I’m not I a BMS Dev nor is the OFM part of the BMS Team, though not be our choice. We’re just a bunch of people who enjoy BMS. So, any changes would be in the OFM db only. -

True, Molni. What I saw in yesterday’s testing was that the Blk 2 is not a Magic Bullet. You can’t go wildly off boresight. It also can be decoyed by flare, despite the link .
As stated previously, I’m still learned how to use it. Fegeleinn, I would welcome on procedures or tactics you’ve found for implementing it in 3D -
@drtbkj
“It also can be decoyed by flare, despite the link.”- If the missile is in the terminal phase (which is set to 7nm, where it should turn on its seeker and start looking for targets) then it can be decoyed by flares, otherwise it shouldn’t get spoofed by countermeasures during mid-course guidance. Also, there is something like this (doesn’t occur often, but still does from time to time)
Since block ii can re-acquire targets, i think what happens is once flares burn-out it loops back into search and DL mode…
“I would welcome on procedures or tactics you’ve found for implementing it in 3D”
- You might try lofting missile manually by 5 to 10° thus increase the maximum range little bit. (I didn’t include auto-loft) And of course try to keep the radar lock as much as possible becuase sidewinder is way less accurate compared to any ARH missile in INS mode.
Also, it seems that Datalink connection is somehow tied to missile seeker gimbal limits, Even with a modified F-16C with 360° sensor and radar coverage, missile doesn’t enter into Datalink phase if target is out of gimbal limits and instead goes full-maddog.
Edit:
AIM-9X Blk.II with modified seeker gimbals (to simulate F-35 w/AIM-9X Datalink at WVR):
-
@Mav-jp - affirmative. But from what I gather the Mafia also does a lot of it’s own coding. Which isn’t out of scope for consideration, when looking at a lot of the add-ons I use for BMS in support of my cockpit project.
-
@fegeleinn - a -9X doesn’t “turn on it’s seeker”…it is ALWAYS on. It’s just augmented or not.
One of my favorite ways to shoot a heater is on the tone alone - tone/uncage/fire. Leave the radar out of it, and they never know what hit them. -9X allows me to do this farther off-boresight.

What are you talking about ? The maffia does zero coding as they don’t have access to BMS source code !
-
@Mav-jp - I’ll believe they don’t do any BMS coding, but I won’t put doing add-on/utility coding past them…

Hi, Stevie. Actually, we do not have hard code access.

This is what I’ve seen as well. My testing to date has been in DF Furball. In that situation ranges are shorter, 10 miles or less. At 10 it’s guiding. below 7 is when the missile can be spoofed. The AI cooperates in that testing with lots of flares.
BTW, do you launch it with seeker caged or uncaged?Since block ii can re-acquire targets, i think what happens is once flares burn-out it loops back into search and DL mode…

Today I’m going to test for range performance

Concur.Testing is still ongoing, but a 45 deg. forward cone works pretty well. At closer to 90 deg. I’ve had a couple seem to not guide.
Edit:
AIM-9X Blk.II with modified seeker gimbals (to simulate F-35 w/AIM-9X Datalink at WVR):Are the gimbal limits 90 deg? I’ve read different things, from 40 deg. to 60( due to aircraft’s system limits) to 90. I’ve also read “within 15 deg. of the gimbal limit.”

@drtbkj - Understood…and I’m not talking about hard BMS code…just your stuff.
