It is best to drop your fuel tanks before landing. The fuel tanks will not refuel with your plane or get replaced if they are still on the jet. You can work around this by opening the AAR door which will allow some transfer of fuel from your internal tanks into your bags(this usually doesn't fill up the bags entirely for me, YMMV). You can also just take the tanks off and put them back on again.

@NineLineAny chance of this getting looked at again?

The roadmap has been updated to list: Current Litening/LANTIRN mash-up targeting pod to true LANTIRN targeting pod. What does this mean? Does this mean we will get both LANTIRN and LITENING pods with differing symbology, or will the LITENING be removed and replaced with a LANTIRN? Etc etc. (old thread was locked)

I checked this after the january patch which fixed the inaccuracy issues I'd reported previously. Kinematics and launch ranges are the same as before the january patch. Unless it has somehow been stealth changed nothing should be different.

I address this exact point in the last paragraph of the OP. I am not asking for the missile to have magic terrain avoidance. I am asking for adjustments in guidance laws to reduce the chance of the missile hitting the ground when targeting diving targets. Did I not make this clear enough in my original post? If so I will add clarification.

To prove my point about this not being an out of parameters shot kinematically, here is a track with the target jamming, so the missile has no problems acquiring the target here. Aside from the strange (control damper?) behaviour here, this is literally an over the shoulder shot that hits its target perfectly due to it acquiring the target properly. This was only my second run trying these shots, you can definitely get the missile to go even further off bore than this. https://streamable.com/q1d14a 120_megahobs.acmi 120_megahobs.trk

The AIM-120 is currently very easy to drive into the terrain. When flying near terrain or trees it is possible to make the AIM-120 fly into the terrain with relative ease by flying downwards for a short period of time then pulling up again. Presumably, performing such a manoeuvre puts the predicted impact point somewhere deep underground which the missile does not account for, it then flies into the terrain. Obviously, this problem gets worse as soon as you are not flying on perfectly flat featureless terrain. As soon as trees, buildings and other map objects come into the equation driving the missile into terrain becomes much easier. I am not asking for the missile to have perfect terrain following/avoidance capability, but some adjustments like not allowing the missile to fly below the target under some circumstances, or making the missile recognise ridiculous predicted impact points would go a long way in preventing the missile guidance from being exploited in this way. 120_grn_4.acmi 120_grn_3.acmi 120_gnd_2.acmi 120_gnd_1.acmi 120_grn_4.trk 120_grn_3.trk 120_grn_2.trk 120_grn_1.trk

I showed that exact scenario in this video(AI set to fire at max range), the missile still goes active. As far as I can see, the missile always keeps its radar on, even in HOJ. https://streamable.com/ol0rcr

the aim120 never burns through any jammer Except that it quite literally does. There is as far as I know no situation where the AIM120 will passively guide onto a jamming target without giving an RWR warning. https://streamable.com/ol0rcr Missile is fired in BVR, as you can see the missile is clearly in HOJ as it doesn't loft. And as you would expect, I get a missile warning from the missiles radar. As the missile is closing in I start toggling my ECM, and you can see the missile start twitching as it starts switching from HOJ to normal PN. https://streamable.com/rythpd Here you can see me toggling ECM while defending the missile. As I toggle ECM on and off you can see the missile switching from HOJ to PN guidance repeatedly. Can you show me an example of an AIM-120C being fired in HOJ and not giving an RWR warning to its target?

Thats exactly what im trying to establish here. Considering its at a very close distance to the target and its a modern missile why should it not be able to burn through? For arguments sake, the missile wont even burn through extremely outdated jammers like on the mig21(i know dcs only has three jammer types) If this is the case, why does the missile give me an RWR launch warning when guiding onto me in HOJ? https://streamable.com/fzb6dh

Bomb accelerates from mach 1 at release to almost mach 1.3 at impact

Small and not entirely unrelated sidenote. Setting the proximity fuse distance to equal that of the killDistance attribute like every single other missile in the game, hhg1&3 will both hit their target.

Issue mentioned in first post is now fixed, but you are still able to dodge 120s in any situation by pulling a high G manoeuvre one or two seconds before impact. This is probably an inherent issue of HOJ guidance, but that brings me back to the points I made in the main post. Why does the missile not burn through the jammer as it gets closer to the target? Hopefully we can get some sort of insight from ED on why HOJ is implemented the way it is for 120s. For a modern missile to be able to be defeated by pulling a simple high g pull is a bit ridiculous in my opinion. 120_hhg_2.trk 120_hhg_3.trk 120_hhg_4.trk 120_hhg_1.trk 120_hhg_4.acmi 120_hhg_3.acmi 120_hhg_2.acmi 120_hhg_1.acmi

AIM-120s fired in HOBS conditions do not acquire their target if the missile does not acquire the target instantly when coming off the rails. In my test setup, I am firing a 120C at a target flying straight and level at varying degrees off bore. The name of the track denotes what degrees off bore the target was when weapon release was pressed. If the target is slightly (~1-2 degrees) out of gimbal limits, this means the missile will never acquire the target. 120_hbs_38 - 38deg weapon release, 51deg motor ignition - 59deg first fin movement. As you can hear on the friendly radio, the missile acquires the target practically instantly when coming off of the rails and has relatively little issue guiding onto the target and killing it in a practically over the shoulder shot. 120_hbs_40 - 40deg weapon release, 54deg motor ignition - 61deg first fin movement. Despite only being a few degrees more off bore than the previous shot, the missile never acquires the target here. Likely due to the fact that the target was not within gimbal limits initially. Furthermore, the missile can be observed flying downwards, which is unusual considering the target and ownship are both flying straight and level, the missile should have no reason to fly downwards here. Additionally, a few seconds after launch, the missile has manoeuvred enough to put the target pretty clearly within gimbal limits. The target is flying straight and level, and the missile is being supplied correct and up-to-date datalink information. As the missile has an INS, is it not reasonable to assume that the missile should be able to guide itself onto the track of the target here despite it initially being out of gimbal limits? Aside from that, the missile should have plenty of energy and manoeuvrability to hit the target here, so I do not think this is an out of parameters shot. 120_hbs_40.acmi 120_hbs_38.acmi 120_hbs_40.trk 120_hbs_38.trk

Same problem seems to occur when shooting targets with an altitude difference. The missile will consistently acquire the higher target instead of the intended target. Here you can also observe the missile receiving false datalink information and snapping. 120_acq_1.acmi 120_acq_1.trk

When setting longer routes for the AI through tactical commander or game master using set path weird pathfinding often occurs. Specifically, when the pathfinding algorithm initially decides to go offroad the unit will avoid roads for the rest of the path set. This results in the AI going offroad unnecessarily and in some cases getting stuck. In the attached tracks there is a torture test with the AI Roland being placed in the middle of Damascus on Syria. When setting a long route, the AI decides to go off-roading in the middle of Damascus through the buildings, despite starting on a road and the route being perfectly navigable while staying on roads. The AI in all cases starts having extreme trouble with navigating through the city, eventually getting stuck after driving through buildings or over obstacles. ca_pf1 https://streamable.com/wzhlm9 ca_pf2 https://streamable.com/1gx74g ca_pf3 https://streamable.com/ej333w ca_pf3.trk ca_pf2.trk ca_pf1.trk

The Ks-19 does effectively zero damage to non ww2-damage-model modules. You can happily fly straight and level through hundreds of flak guns and suffer basically no consequences. Keep in mind that if a more sensible amount of flak guns is used, they are effectively harmless as the flak round do nothing unless they score a direct hit. ks19_dmg_2.trk ks19_dmg.trk ks19_dmg.acmi

Small bit of testing with varying altitude differentials. All behaves roughly the same except with a 30k altitude differential where the missiles still both go for the wrong target, except its now the leading not the trailing aircraft in formation, weird stuff. Its definitely picky in what sort of direction you are attacking and what formation the enemy is flying in. Surprisingly easy to encounter in practise though. The standard fighter formation if you don't change anything makes this behaviour occur if you attack them from a left offset. @BIGNEWY @NineLine any chance of this report getting a look? 120_grp_plus30.trk 120_grp_plus20.trk 120_grp_plus10.trk 120_grp_level.trk

I agree

The missile might explode too far away from the target to do critical damage with a higher proximity fuse setting. F-14s can already occasionally survive AIM-120 hits.

From a bit of testing there is a lot of improvement to be had with a higher proximity fuse setting. A 15m proximity fuse is fairly safe with our current warhead. Stealing @vtaf_archer 's barrel rolling track from another post and replaying it with a 15m instead of 7m proximity fuse makes the missile hit in this case instead of having a near miss. 7m prox: https://streamable.com/yx62kq 15m prox: https://streamable.com/iy8ym3 120_vs_barrel.trk Taking one of my older tracks which results in a miss with the 7m proximity fuse, it now also hits with a 15m proximity fuse. 7m prox: https://streamable.com/9ndhts 15m prox: https://streamable.com/5zo7z5 120_barrelroll_HALFRANGE.trk You might run into problems when dealing with modules with more robust damage models (F-14, Mig21) however I don't own these modules so cannot really test this in practise. When testing with the mirage f1 (reasonably tough damage model, often "survives" missile hits) I didn't run into any problems.

You are at 40k shooting down at targets at 16k. This is very different from the tracks I show where I am co altitude with the targets. I also cannot tell if you have AI enabled on your target. You also fired your missile offset from the targets. All of this could mess with the geometries of the missile shot which could cause the behaviour to not occur. I will do some more testing to see if anything changes with different altitude differences later.

@NineLine any update on this?
