Hoggorm Posted February 20, 2017 Share Posted February 20, 2017 Hi, I have a lot of problems getting the BK90 Mjölner to work on targets in valleys. I have no problem using it over flat terrain, but once there are some hills I never hit. Even if the gliding dispenser flies straight over the target. Can it only be used successfully against targets at flat terrain? I'm sure my position is correct using terrain navigation (50 is the last two digits before deploying the weapon). If you have Tacview you can see a couple of examples here: https://dl.dropboxusercontent.com/u/16066714/Tacview-20170219-210438-DCS.txt.acmi The BK90 flies straight over the target and crashes in the mountain on the other side. One infantry is killed... https://dl.dropboxusercontent.com/u/16066714/Tacview-20170220-213440-DCS.txt.acmi 1st attack. The BK90 flies straight into a mountain before reaching the target. For some reason the 2nd BK90 is not launched. Instead a Sidewinder is fired... 2nd attack. The BK90s are unfortunately launched a bit too early, but they appear to crash into each other before hitting terrain. 3rd attack. I gave up and loaded some M/71 with chute instead. Any help would be appreciated! Link to comment Share on other sites More sharing options...
marluk Posted February 20, 2017 Share Posted February 20, 2017 I have no answer to the specific question but I would like to confirm the problem when Sidewinder has been launched instead BK90. That happens to me once. The second run went ok. I think I've done everything like the first time. Also, I had success only with mixed type of munition. The other two types didn't destroyed anything regardless direct hit.

JanTelefon Posted February 21, 2017 Share Posted February 21, 2017 The BK90 works well over hilly terrain. You may want to increase the cruise altitude of the BK90 to 150 meters if there are sharp climbs. Link to comment Share on other sites More sharing options...
Xxx Posted February 21, 2017 Share Posted February 21, 2017 The BK90 works well over hilly terrain. You may want to increase the cruise altitude of the BK90 to 150 meters if there are sharp climbs. What is the code to enter after 91. The manual is not too specific. VALB (selectable) – The weapon’s altitude is set by the value in address 91 in mode TAKT/ IN. Possible intervals is set to 30 – 500 m. After clearing TAKT or entering value 0, the default altitude of 60 m is set. STD (Standard) – The default value of 60 m is set. Attack altitude The attack altitude is always 60 metres AGL.

Hoggorm Posted February 21, 2017 Author Share Posted February 21, 2017 (edited) The BK90 works well over hilly terrain. You may want to increase the cruise altitude of the BK90 to 150 meters if there are sharp climbs. Thank you. I just tried that on two attempts. The first attempt I approached perpendicular to the valley. Both missiles flew over the target but impacted the mountain on the other side. No enemy units were killed. On the next attempt, I flew down in the valley. This gave the best result so far with some enemy casualties. Very nice! I assume that had I asked for a long attack instead of a standard I could have taken out much more. But what happened on the first attempt? Why did the missiles fail? Can it be a bug since the missiles crashed so soon after the target. In the real world, I guess the ammunition would have been released the moment the missiles flew over the target. So, if it crashes a moment later that would not matter. Can it be that the missile and ammunition is considered one until the actual explosion occurs? My next thought is regarding the release altitude over the target. The checklist calls for an AGL altitude between 50-500 meters. I was indeed just over 400 meters AGL. But I was about 1000 meters over the target (QFE). Can this be an issue?

Ramstein Posted February 21, 2017 Share Posted February 21, 2017 dispersal of the bomblets seems to be best if BK90 is set a little bit higher... of course the dispersal parameters can be entered into the computer..

Hoggorm Posted February 21, 2017 Author Share Posted February 21, 2017 What is the code to enter after 91. The manual is not too specific. I enter, in TAKT: 91150 -> LS for 150 meters. 91500 for 500 etc. Link to comment Share on other sites More sharing options...
Xxx Posted February 21, 2017 Share Posted February 21, 2017 I enter, in TAKT: 91150 -> LS for 150 meters. 91500 for 500 etc. Thanks. Its a powerful weapon indeed. Reminds me a bit of the JP233, certainly in its ferocity, but of course we can't knock out runways with the Viggens bk90 cluster bomblets?

JanTelefon Posted February 22, 2017 Share Posted February 22, 2017 I just remembered something. Make sure you don't launch the BK90 before the time line has reached the launch zone markers. I f you do, the BK90 might reach the target but will only fly over without deploying the submunitions. Link to comment Share on other sites More sharing options...
609_Relentov Posted February 22, 2017 Share Posted February 22, 2017 One sidebar question regarding the BK-90 - when observing them via externals, I've never seen the submunitions disperse (although later I see the explosions over the target). Just wondering if this is still a WIP and we will see the animations, or it was decided to not show it to save FPS. Has anyone else seen the submunitions disperse (like we get with the CBU-97 for example)? Link to comment Share on other sites More sharing options...

Sporg Posted February 25, 2017 Share Posted February 25, 2017 Sorry for a bit OT, BTW is BK90 working in MP now? After the second patch it was reported that the BK90 only works for the host in MP. LN should have a solution, but since there's been no patch since, it is still not working.
