The AIM-120 'AMRAAM' - History, Design, Performance & Discussion

that was not the question, the question was if the Aim120 already had a lock and then loses it. what happens then in detail?

120s should have smokeless engine. I saw i think one bug report on it with it being acknowledged. Did devs said anything else about it or we are going to have full on smoke parade with 120s even though we shouldn’t? 54C same deal.

Seems intentional for now

With the MP change, they should probs wait a bit for the community to acclimate to radar missile combat tbh, as much as i hate the fact they’ve been dragging their feat on the AIM-54C issue for so long. Granted, there isnt any indication gaijin is looking at ever fixing anything about the AIM-54C, so were still stuck with the idiocy that is the AIM-54A being a better missile than the C in-game in every way but inertial drift…

@_David_Bowie @InterFleet any potential news on AIM-54 fixes?

Just me or the AIM-120 loses it’s energy very fast

It is a lighter missile, to be expected. Perhaps it can be looked into.

I find it to be the opposite, loses speed way slower when compared to all other fox 3’s

It doesnt, of all the radar missiles, its the one that tends to lose energy the least (in a straight line atleast).

Spoiler



Now that I look at these graphs again, the AIM-120 would even outspeed the AIM-54C given enough range and battery life, with the 6000m launch range graph actually showing this nearly occurring at 60km, which is even more questionable than the AIM-120C-5 doing it…

then all the other fox 3’s are ass

I mean, kinda yeah…

  • PL-12/AAM-4 are heavily suspected to be underperforming kinematically (probs for balance)
  • French mains claim the MICA is underperforming at range (likely has some truth to it)
  • As much as I like to rip on the R-77, its hard to say exactly how well it matches expected performance since its the only missile with grid fins. It has a planar fin drag profile ingame afaik though, so either way theres gonna be some pro’s and cons relative to irl performance.
  • Derby seems to perform the worst, but its also a short range missile adapted for medium ranges, so thats kinda to be expected. It seems to perform well at shorter ranges from what ive hear, playing second only to the MICA, but those ranges arent covered in this graph.
  • AIM-54C could easily perform better with a change to its guidance/loft code, which we know it had improvements in irl, but i dont make bug reports and the info we do have (we know it has a completely new and vastly superior guidance section and was specifically upgraded to improve its capabilities against sea skimming AShM’s and highly maneuverable fighter sized targets, implying it would need as much terminal energy as possible) doesnt fit gaijins world view, so its never gonna be fixed.

Overall though, all the loft profiles seem pretty trash and generally just thrown together, which is probably one of the biggest reason some of these missiles are struggling more than they should at range.

what a surprise pl12 is underperforming… didnt see that coming

Might be a lil outlandish, but how would the AMRAAM D perform here hypothetically compared to IRL?

I can make some in-game custom missile files to test hypothetical future missiles.

I can understand it being copied off the AIM-120A for balance, but being worse than it when it should be better is like, why bother adding it when they also have access to the AIM-120A (which should be Bs but that’s nitpicking)?

In fact PL-12 & AAM-4 better AIM-120A & AIM-120B 25%. but now placeholder like AIM-120A

I might hope gaijin buff AAM-4 & PL-12 better AIM-120A & AIM-120B AMRAAM 20% for next major update

My point was that it’s actually worse than the AIM-120A, which means I don’t even know why they added it. We’re lucky we can use the AIM-120A on the F-15J as there’s no reason to use the AAM-4 right now when it’s actually worse in all departments besides explosive filler.

Gaijin could not get into the grid fins and TVC

Hopefully Gaijin gets on that, there isn’t much left to add in terms of missiles which don’t have TVC.

They’ve already got the R-73, SRAAM, and MICA, but AIM-120C-5, All 5-th gen IR, and probably a lot more all use TVC and its going to need to be modeled right soon.

Grid fins, I can see them just leaving though. Only the R-77 and R-77-1 use them, so why waste time? As long as they can do it close enough, it shouldn’t be too terribly dramatic.

If they do not model the transonic drag properties they can either make the missile match higher than 1 mach launch scenario for higher altitudes and cause overperformance at medium and low alts… or they can model it for lower speed launches where it will drastically underperform in BVR. They’ve sort of compromised and made it draggier than it needs to be when launched at high speed… so the latter.
