edineygomes Posted April 1, 2017 Share Posted April 1, 2017 I added two ships in the mission editor. I created an ajs-37 with a waypoint over the targets. (M1) Launched the missiles with ANF master mode, the weapon selector in attack mode, release modein serie and target mode grupp. The missiles do not detect targets and pass through. Altitude 100 meters QFE 1013 Am I doing something wrong? Link to comment Share on other sites More sharing options...

Cobra847 Posted September 12, 2017 Share Posted September 12, 2017 How close together are the two ships? The Grupp mode requires a specific arrangement for the ships to work (A line) Nicholas Dackard Founder & Lead Artist Heatblur Simulations https://www.facebook.com/heatblur/ Link to comment Share on other sites More sharing options...
Harke Posted September 12, 2017 Share Posted September 12, 2017 3 ship in line espaced by 0.40nm each, managed to kill one in enkel but grupp only ignore them Link to comment Share on other sites More sharing options...

RagnarDa Posted September 13, 2017 Share Posted September 13, 2017 The targets need to be in a line in depth from the point of view of the missile. A little picture to llustrate (M is missile and <000> is targets). The missile is coming from the left. Correct: --M-> <000> <000> <000> Not correct (will miss): <000> --M-> <000> <000> 1 DCS AJS37 HACKERMAN There will always be bugs. If everything is a priority nothing is.

Harke Posted September 14, 2017 Share Posted September 14, 2017 OOooooooo..... :doh: but ? why it isn't working in the first screenshot ? 0 0 --M--> 0 0 0 0 bad ? Link to comment Share on other sites More sharing options...
JanTelefon Posted September 14, 2017 Share Posted September 14, 2017 I think the ships might be to close together. I'm not sure what the depth separation needs to be, but it might be more than that. This is tech from the 60:s after all. :) Link to comment Share on other sites More sharing options...
Jediteo Posted September 14, 2017 Share Posted September 14, 2017 (edited) The issue is that the seeker does not recognise groups in width, only in depth. This is a limitation of the seeker design and the rather small scan area. In the case the missile detects ships that are not recognised as being a group, it will not lock them and proceed to try to find other targets behind them. The group mode should only really be used for large convoys. Consider the possibility of the first ships detected being escorts and the juicy transports are just outside of the search zone. If the missile would see the escorts as a group, there would be no way to hit the transports. It was assumed at the time the ships would be in large square formations (consider that the missile started development within 10 years of the end of WW2 and entered service in 1962). The prerequisites for being a group: At least 2 targets detected in depth. The ships are not more than 2700m away from each other. As illustated in case 1. The ships are in a single column and are attacked from the beam. In this case, the missile detects the ships, but does not recognise them as a group. If the targets instead would be attacked from the bow (front), the missile would see the ships as a group. Either change the approach vector, or use the single target (ENKEL) mode instead which would lock the first ship detected. In case two, the ships are arranged in a row, with less then 2700 meters between them. Ships A, B, C are in a line. The 04 sees them as a group, but does not consider X and Y among them. Depending on the missile presets, either the target row 1 (ship A), 2 (ship B), or 3 ( ship C) would be locked, by default the selection is random(changeable in the Mission Editor). In summary, attacking groups of ships requires some planning, in particular "lining" the ships up for the missile. So either use the single mode (ENKEL) or try to attack the convoy so that the missile can see 2 or 3 ships in depth.

Harke Posted September 15, 2017 Share Posted September 15, 2017 (edited) Awesome answer... wow thank you! this thing must be in the manual with this level of detail !

Quip Posted September 16, 2017 Share Posted September 16, 2017 It is in the manual in fact: Grouped targets is selected by setting the targeting mode selector to GRUPP. In this mode, the contacts must be within 2700 metres of each other in depth. Otherwise the missile may miss the targets entirely. If the missile detects a grouped target, it will select one of the contacts at random, leading to multiple missiles selecting different targets.

goestrip Posted October 1, 2017 Share Posted October 1, 2017 I had the same bug this week in 1.5.x, but after some testing it seems to be related to the ship you use. With the russian dry cargo ship (ivanov i think), i could never get a missile tracking them in SP or MP. But as soon as I changed the boat type (to a tanker elnya, or military boat) it all worked, whatever the boat formation or my approach angle. So I reckon it's a weird bug linked to this particular ship type. Link to comment Share on other sites More sharing options...
