Wouldn’t surprise me (looking from the container) with 6 kilos of RDX, with what looks like a spaced percussive cap, would have a similar penetration to the Swedish 132mm psrak m/75 rockets.

I believe that’s a war crime

The small anti-personel submunitions can either land or in most cases set to detonate at a certain altitude above the ground. An aerial detonation is often preferred to increase the area affected by the fragments.
The big anti-tank submunition folds out two wings and camera and starts spinning to try and find a target. When they find one it detonates the shaped charge in the air. It is not the same type of shaped charge as most others (RSV III in Swedish. (RSV = Riktad Sprängverkan = shaped charge)) which forms a superheated jet at high velocities but instead a projectile forming shaped charge (RSV IV in Swedish) which has less penetrating power than a similar sized RSV III but much greater range as it forms a singular projectile with much greater mass but slower velocity than the thin metal cone in an RSV III.
This is not a downside since the roof armor of any armed vehicle is thin enough for it to go through. And since it detonates many meters above the target any active protection system will not shoot it down since it is out of range for them.

I have never heard of BK90 guiding itself onto the target besides the main capsule
But the rest I knew
The BK90 uses INS/GPS to guide itself towards the targeted area and to know when to fire the submunitions.
The MJ1 (the smaller anti-personnel submunitions that fit 3x in one launch tube) are “dumb”, only having a proximity fuze that you can set how high you want it to detonate at. These get spread out over the targeted area and spread fragments harming soft targets.
The MJ2 (the bigger AT submunitions that only fit 1 per launch tube) actively seek out vehicles with IR cameras and laser 3D terain mapping in a sort of wobbly spin. Once it has found its target it does another rotation and then fires the shaped charge, striking the target from above with it’s projectile.
I have not (without much effort that is) found a video of live fire using the BK90 where you can see the targeting submunition but it works similarly to the Bofors BONUS 155mm artillery round and that I have found some good videos of. It also does targeting in more or less the same way and also has an RSV IV.
Here is a video I found going over the Bofors BONUS https://youtu.be/FgNTO-4ukkk?si=ORlOtKXHnWEci0A4
Have you got anything to back this up because that would massively boost its abilities from what i know of it
How would it work if it could not seek out targets? that would entirely defeat the purpose of having it. There is no use blowing a shaped charge in to the dirt and if it could not target anything then it would most certainly only hit dirt.
After finding a manual for it it seems I am wrong in this. I am not 100% sure but might just have been a thought to put in the BONUS submunitions in to the BK90 and never having that happen. This seems to be the case as I found an article sugesting this so it is probable that the MJ2 only have the same proximity fuze as the MJ1.
Though I must say that it seems incredibly dumb to blind fire a precision weapon.
Sits upright and is magnetic so when a tank rolls over it will detonate and blow a hole in the bottom, only other way.
They have proximity fuzes though, they are not mines released. It is basucally just a bigger version of the MJ1 but remove the 2000 balls and replace them with a EFP.
We do have AT mines that uses EFP as well but these are not mines. They are set to detonate either at a set altitude or right when they hit the ground.
Looked into it, it uses MMW-Radar and an IR sensor to search for an armored target, lock, and guide. So yes, it (Musjas 1)would be a fully automatic munition after launch.
I feel like that might be a bit OP in ground, but I guess they could do a Brimstone and only give it the IR lock, so if engines go off or they go into smoke they lose lock similar to the AGM-65 that uses the IR locking system.
Where did you find that info? Most sources I found said that both MJ1 (small fragmentation submunition) and MJ2 (big AT submunition) have the same proximity fuze meaning that they both are just gliding down with their parachutes and blow up when they are at a set altitude, no targeting built in.
At this point I don’t know, I’d have to have someone read the manual it tell me what it says about the munitions.
I did read the manual, it said that they have the same “zonrör” which is Swedish for proximity fuze. I know Wikipedia describes the MJ2 to work the same way as Bofors BONUS artillery submunitions but the manual and just about every other source like Arboga Robotmuseum says otherwise.
Yeah, I know all the general military terminology, it’s just the general Swedish I don’t understand. Also, otherwise as in they aren’t guided?
Yes, as I have stated in previous messages. The one you replied to. From what I have found they are unguided. Glide down with their parachutes and detonate when the proximity fuze tells them to.
The Bofors BONUS 155mm artillery round has two guided sensor fuzed submunitions. You can see them working if you search for it on youtube.
I also linked a video a bit earlier in this topic.
Yeah, there are a lot of DCS videos that go more in depth to it, it’s not guided, but the idea is recon gives you location, you ripple off 4 in long or wide mode on that location and then launch and hope the mass amount hits.
Suggestion passed to the developers for consideration.
