Rapier SAM Blind Fire TR radar and optic tracking device unable to sort targets. Both tracking sensors watching same target when more than one exist inside its WEZ. Because of that, the capability of such system is degraded. If only single target in WEZ - its ok if both tracking same. But in multiple target scenario, there must be better script to sort targets. Now both sensors tracking outbound target, when at the same time there dangerous hot target ingressing. Problem of DCS Rapier not end by this, by continue with script system unable to evaluate Pk of close shots and aspects of targets with its speed. What in case of hostile helicopter may seem be nice feature minRange = 400m - this is very very bad idea against every aircraft flying around. The missile just cant steer so quickly and it just waste of missiles (first 1 second the missile fly just streight in 20° up angle and another sec or two it need to get back on commanded LOS). Missiles at this point often fired in salvo of more than 2 msls. Just very few flybys, and system needs to reload entirely. Together with LOW (another DCS bug) max speed of just M1.86 instead of M2.5 ... the result Pk of fully reloaded system is worse than any other SHORAD SAM system in game. Fix issues mentioned above...and it will very nicely scripted realistic SHORAD system in DCS.

Hi Everyone, I was doing some tests with the Rapier and it seems that when firing at low altitude targets, the Rapier missile will do an extreme yoyo, going high, and then rapidly diving, only barely managing to pull-up and avoid a collision with the ground. In the first track I have a Mi-24V flying near enough perpendicular (but not notching), a launcher and an optical tracker, with no blindfire. The Mi-24V is @200m AGL (ΔH ~ 195m), flying at 200kph - well within the engagement parameters for Rapier (according to the Rapier_FSA_Launcher.lua the minimum altitude is 50m). The first missile climbs, then performs a steep dive, only barely managing to pull-up to avoid a collision with the sea, and eventually hits the target. The target descends, another Rapier is fired, this time crashing into the sea. The third missile repeats what the first missile did, and barely manages to avoid colliding with the sea. In the second track I have everything set-up exactly the same, only now the helicopter is set to an altitude of 100m (ΔH ~95m), which should still be inside the Rapiers engagement altitude; this time every missile ends up flying into the water. It should be noted that the missile behaves the same when paired with Blindfire or not. Now this could be caused by probably 1 of 4 factors: The missiles are initially elevated too high - unlikely, the missiles should elevate based on range and altitude. The missiles are too aggressive in trying to centre themselves in the operators reticule (this is broadly what an optical SACLOS guidance scheme tries to do) - unlikely as this might play a part into reducing the minimum range, which is probably a good thing for a short ranged system. The missiles aren't responsive/manoeuvrable enough - not sure, I can only base on my expectations (which may well be off). If you draw a line between the optical tracker and the target I'd expect the missile to follow that line more closely (like the Tunguska), not loft way high above it and then make an excessive dive past it. The AI operator - here I think lies the issue, the AI operator most likely keeps the reticule as centred as possible on the target, this makes sense, however it is most likely (from my reckoning at least) causing this issue, if not for the above 3; a possible remedy is to have the operator aim high (at a similar elevation to the one the missiles are fired at), and then slowly bring the reticule down (so that it is on the target after about 2 seconds). Hopefully, this will result in a more gradual descend and the missile won't perform such an aggressive dive that it can barely climb away from. This should also increase the amount of energy the missile has, which is beneficial for achieving a hit. There is this video of a Rapier launch failure (here the system is the much more modern FSC variant, but AFAIK the command-guidance scheme is the same, just instead target tracking is done automatically via EO/IR and/or RADAR). In DCS it seems to do something similar every time it's launched at a low-altitude target. Can anyone confirm what's going on here, and how Rapier should behave? I've done some digging but can't find much, other than basics. [sidenote: @Tippis contrary to your excellent reference wiki Rapier in DCS will in fact launch with just the optical tracker and without Blindfire, under an optical SACLOS guidance scheme, as it should IRL].
