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

I’m just saying you could try to make a case that if the aoa is different between the a/b and the c-5/d, then you could make the case that they shouldn’t be the same in game and that the increased fin aoa would lead to increased maneuverability. At this point its never going to change because Gaijin don’t like to actually do their jobs when it comes to research and relies on the community to do the legwork for them out of laziness.


I/W = energy capacity
where I is thrust x time and W is mass x gravity
so for war thunder it is (23000knx6s)/(175kgx9.81N) = ~80.4 ish
quite close to the 79 value

So basically how effecient its motor is given its weight

Reducing its burn time from 6 to 5 second would be more of a buff than nerf for current meta, if the total thrust remains same

yeah. fun fact r-27er is actually quite a bit better than r-77 which is to be expected at 94.
aim-120a for example would be 75, so it’s actually worse than r-77 but r-77 has much more drag
aim-120c-5 has 76, so it’s slightly better

I wonder how fatasses like aim174b r37m and pl17 would fair

Do we have info for r33 and base r37?

Well, 15km and 1800km/h aircraft launcher; 12km and -1200km/h aircraft targeted, it kinda did it
Could stretch the launch conditions even more to simulate a F-22 at 20km of altitude (mach 2.33 terminal speed and 235s of flight)

Unsurprising the dev was provided with this information in the max range report. Outlining that AMRAAM is limited by battery so any maximum range value must reflect the time limitation rather than a kinematic limit.

Is there any chance we will see different lofts programed into the aim120’s? the aim120a i honestly don’t know the loft for, just that the 120b improved it through software updates. The 120c should loft higher to make use of the extra bettery time and the 120d should loft even harder. It’s how it reaches the “50% improved range” figure. As of rn all of the aim120 share the same loft angle in game. Without the extra loft, the aim120d especially cant reach its maximum range with any practicality.

live been out for a while
any change on the 120D?

no. none since dev tbh.

what about bug report progress?

None afaik. They’re still sitting on bug reports from 2 years ago.

Hey, AIM-120D-3 has improvements in the motor compartment (more thrust or more burn time) or still the same as 120D, C-7, C-5?

i guess its gonna be like that for a while

120d3 gets slightly more propellant but the actual amount is unknown.

This is the source wikipedia uses. Its a quote from Jon Norman. Raytheon vice president of requirements and capabilities. Most of the extra range of d-3 doesn’t come from a better motor, but a longer battery life and better guidance algorithms, mostly the d series lofts way harder and comes down almost on top of its targets increasing time to target, but also increasing range and energy in terminal.

iirc its both i think
it has another 5 inch rocket motor and again the logically improve rocket fuel for higher thrust

yeah F3R allows for a tad bit more fuel

there was a debate back then about that, it seems C-5 already uses the 5 incher motor

+5" was added with the c-5. D-3 which is after F3R, added more fuel by shrinking electronics.
