Analysis: Enhanced Within-Visual-Range (WVR) Capabilities of the AIM-120C-5 vs. AIM-120A/B Variants
The AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM) has undergone iterative upgrades since its introduction. The AIM-120C-5 variant (C-5) demonstrates significant improvements in Within-Visual-Range (WVR) combat compared to the legacy AIM-120A/B series, enhancing lethality in dynamic close-range engagements. Key advancements include:
1. High-Sensitivity Fuze (HSF)
A/B Limitation: Early fuzes prioritized medium-range intercepts. At very close ranges (<1 nm), high off-boresight angles, or against low-observable targets, fuzing reliability decreased due to premature activation (clutter/proximity) or delayed detonation.
C-5 Enhancement: The C-5’s HSF employs advanced signal processing and increased sensitivity to:
Reliably detect high-speed closures and low-signature targets.
Distinguish targets from background clutter during complex endgames.
Optimize warhead detonation timing in high-G, close-quarter scenarios. Effect: Increases probability of kill (Pk) in “dogfight” ranges.
2. Upgraded Active Radar Seeker
A/B Limitation: Early seekers had reduced performance against high-G maneuvering targets or under electronic countermeasures (ECM) in WVR.
C-5 Enhancement: The C-5 features:
Higher transmitter power and improved signal processing.
Faster target acquisition at short ranges (<5 nm). Effect: Sustains lock during aggressive maneuvers and ECM environments.
3. Improved Maneuverability & Flight Control
A/B Limitation: Aerodynamic control and autopilot logic were less optimized for rapid post-launch turns at high off-boresight angles.
C-5 Enhancement: Refined autopilot algorithms and minor airframe tweaks enable:
Faster initial turn rates.
Higher sustained G-capability during terminal phase. Effect: Closes “no-escape zone” against agile targets.
4. Reduced Minimum Engagement Range
Combined seeker/fuze upgrades allow confident launches at historically “unsafe” distances. Pilots can engage earlier in merging scenarios with higher Pk.
Conclusion
The AIM-120C-5 bridges the WVR capability gap of the A/B variants through its High-Sensitivity Fuze, advanced radar seeker, and flight control optimizations. These upgrades transform the AMRAAM into a dual-role weapon effective in both beyond-visual-range (BVR) and close-in combat, providing pilots with critical tactical flexibility.

There is no doubt about it Very important,F/A18CL will lose more competitiveness（like what it’s doing now）if the aim120c5 have Extremely poor performance at close range like test server.Fortunately we have essay support.
First, try it on the 120s, you won’t get ‘over the stated max’ period, it simply lacks the AOA generation to do it.
Secondly, define briefly. Because a Python 3 turning 42Gs for half a second doesn’t count as ‘it does more than what the statcard says’, that’s closer to a bug than anything else.
Obviously, that’s sort of the spirit of missile statcards, otherwise Gaijin would’ve revamped them a long time ago.
Gaijin shot themselves on the feet for introducing the 120C5s to ‘balance’ underperforming frames at top tier.
While they balanced the missile on their performance beliefs for ARB purposes, they’re rendering the SLAMRAAM usage as a meme as you’ll have to LEAD an ACTIVE RADAR HOMING missile, otherwise it just won’t turn enough.
hopefully 120C will get a buff before live because IRL it is supposed to be much better for high off bore and harder to notch, but Im not too hopeful on that
they are trying to balance top tier air RB by adding better missiles to the worst preforming airframes, it kinda defeats the point of that when the missiles they add are worse than the current ones
so making a missile useful for close-medium range (the same range you guys say the current 120s performance doesn’t matter) makes it a powerful missile?
God now you guys don’t even try on your troll/ragebait attempts anymore.
Yeah but they can’t just arbitrarily add missiles which are substantially better to balance a platform which isn’t that far behind.
The F18C at top tier isn’t that bad from what I’ve seen, the issue is a lot of pilots using it dont know how to. its not the same as say, the A10 recieving aim9Ls for its introduction as it was substantially slower and without the missiles would be at anyones mercy (for the most part)
I use aim120’s they’re pretty damn good missiles, especially compared to the likes of R darters or Derbies. ever R77s are pretty poor in comparisson (R77-1s) are not.
My point is the F18C isn’t exactly struggling with Aim120B’s and rather than jamming in random half ass upgraded missiles. we should take a patch to properly balance the whole fking game.
You actively trying to dismiss a legitimate topic of discussion as “Troll/ragebait” just because you disagree , does nothing for your image mate.
substantially better missile that is currently worse than the existing ones for shots less than 15-20km which are the most common and important ones in game
Kept on saying it when they add the R-77-1, right around the corner was the C5. Isn’t the surface launched version of the C5 supposed to be a tad different than the aircraft launched version?
I advocate for hte removal of the Kh38MT, im sure you know that.
as well as this, the Su25 at the time was a shitbrick so it was somehow slightly justified.
And then they wonder why theres literally thousands of people complaining about the game, aim9X I really hope doesn’t come to the game soon, at all.
C5 as well is one hell of a jump from the initial C variant as well as far as I know.
They are missing out on so much fking content just to ram newer and newer sht into the game, aim120C-5s yet the EF2000 radar is barely capable of a 20km lock n launch, with its placeholder radar.
Hardly, I’ve found that with the EF2000 its better to run the aim9Ms x 6 with 4 x Aim120s cause long range just isnt that big a deal if you play right, a 15-20km launch is such an easy thing to dodge / notch.
actually they recently rework C-5, i think theres someone around here that tested before and after C-5 rework so now it should be more in line with other AIM-120
its better yes but not substaintially better anymore
See hte issue? now were gonna have people demanding that they add the correct version, or better, the game can barely handle SARH missiles never mind the ARH missiles were jamming in here
weve went from the 1970s to 2003 in about 3 BR steps its ridulous
