I will look at the sensor view and see what’s happening
I was looking at the missiles spredsheet and I noticed that in the guidance subgroup the major difference between missiles guidance is located in the PID terms. Does anyone know what they mean?
In my understanding they are the "biggest error"possible in the calculation, so smaller the number the better?
They have an impact on the trajectory or on the tracking capabilities (harder to notch)?
It is normal that they are different for such different missiles. PID values dictate how much the missile tries to correct to hit a target. Tuning values, basically.
AIM-120 absolute maximum speed in-game per the files is mach 5.08 (1500 m/s) at very high altitude. The top speed of the missile should therefore be achieved at a minimum speed of mach 2.1 at 12km altitude. The loft profile should bring it into thin air relatively quickly. A higher launch of 2.4 mach should bring the missile to a theoretical top speed IRL closer to 5.1 - 5.2 mach.
In the case of the R-27ER it is missing a top speed of 100 m/s from 5km+, I think in-game the AMRAAM is much closer already to its’ real world top speed in comparison and may even be overperforming in very low altitude scenarios (as is the R-27ER and other longer range AAM’s).
The 27ER, much like C5 is missing top speed to the engine limit isn’t it? Same for 120B, they all clip at 5400km/h IAS(iirc).
Any missile with a top speed above 5 mach at altitude would hit the limit, yes, hence my comment. The R-27ER is missing 100m/s from it’s top speed as early as 5km whereas the AIM-120B is only missing speed when launched beyond 2 mach and at very high altitudes.
Yep, i really hope they fix this limitation. A it would buff the R-27ER and pose more questions on which aircraft use it, for potential historical changes, and some missiles like ASRAAM will be heavily capped by such a limitation if it isnt removed.
All future ordnance that can be added to the game in regards to medium or long range AAM’s are hampered by this limitation. Any that are not are sparse exceptions, such as AIM-7P.

Pretty much, especially with the Russian hypersonic missiles which can really offer a unique capability to Russia, I would expect it to be fixed pretty soon.

yep, certainly needed atleast for next year
That’s um, a bit better than some of these listed here…
I mean Aim-120D levels of range… but ya know, would be more than happy to have it added for Israel rn :)))
how much heavier is ER over standard Derby?
4kg apparently
ok now this makes no god damn sense
Official document from Rafael for the Derby
Official document from Rafael for I-Derby ER…
this is sloppy marketing on Rafael’s part. there’s typos in the document
does ER even have a new motor? or is it just a guidance and battery life improvment?
I don’t see how, it’s below average compared to the rest of the list.
It’s not about how much heavier it is, it uses a dual pulse rocket motor. They drastically reduced the weight and size of the electronics to allow more room for motor / propellant. It’s essentially what is being done to the MICA to make the MICA-NG.
The old Derby is based on the Python 4 which still uses traveling wave tubes as opposed to solid state electronics. The I-DERBY ER switches to solid state and miniaturizes stuff.
It is believes the I-DERBY ER either comes with an IR proximity fuse or combined the proximity fuse into the radar seeker / dome. No images of the real missile show any sort of viewport for the proximity fuse sensors.
Even the AIM-120D has visible target detection device section.
@BasherBenDawg8 Do you have pictures of the I-DERBY ER that aren’t mockups or training rounds so we can verify if there is a TDD and if so, what type?
AIM-120D is purported to be 180km in range.
MICA EM and Derby SR have an identical vertical launch range of 20km.
MICA NG EM and Derby ER have an identical vertical launch range of 40km.
MICA NG EM is given a stated maximum range of 130km.
I’ll let you guys do the math on whether Derby ER is AIM-120D level of range.

I mean technically the Aim120D will also come first because it was made in 2006 while Indian tested theirs in 2021.
But there ranges are not equal they have different things to match the Aim120D still not as good though
