Wow bro, I’d like to know if the Derby with the yellow stripe will be the same as the one you can see on the Kfir (which has a blue stripe) but maybe that’s the only difference.
I would like to think that it is due to differences between users. For example, there is also a blue line in the SU30MKI, even though the missile is a different colour. I don’t think it’s relevant to look for that as a difference. Also, the Kfir is carrying a Derby-ER, as confirmed by the photographer’s statement in the picture.
They sure do. Which is why that last picture isn’t an I-Derby ER, but actually a regular Derby on the F-16B Block 10 4X-ACE prototype.

Even if that’s true, it doesn’t change my point, which is that the Derby and the I-Derby and the I-Derby ER are exactly the same physically
Well yes ofc, but just pointing out something incorrect is all. It’s well know they share the same exterior model (despite some people claiming the rolling fins are different), it’s the propulsion that’s changed. From what I’ve seen it likely has the same seeker as the I-Derby on top of that.
Recap for 2025:
The Colombian Kfir C.10 Block 60 is NOT complete. The following issues and errors have not yet been resolved:
Incorrect primary armament: 30mm DEFA 553 cannon
EEGS mode in the HUD
Obsolete and incorrect sensors: RWR, Datalink 16, SPS-45 (V) 6, EMERALD AES 212 (If they add EW, ECM mechanics).
Since the version included in the game is the most recent (2016), there is no reason why these modifications should not be included.
Likewise, the Python 4/5 (IR) and I-Derby/IDerby-ER (ARH) missiles should be included when they are added in a future update.
Thank you for reading.

With the recent announcement of the potential addition of new weaponry to the game (AIM-120D and PL-12A), perhaps it’s time to add the I-Derby missiles for the Israeli TT, which would improve the few aircraft that won’t have access to increasingly better missiles in all other nations.
Aircraft that can use the I-Derby:
- Kfir C.10 Block 60
- F-16D Barak 2
- F-5TH TCU

The AIM-120D may possibly be added to the F-16I Sufa and the F-15I, which is why the addition of “Made-in-Israel” weaponry is often overlooked by them.
The I-Derby is ingame on the SPYDER, it’s a copy paste of the Derby and if added to aircraft would be the same. The Derby we have ingame already preforms exactly like a true gaijin I-Derby implementation would.
Also technically speaking the F-16 Barak IIs can’t use the Derbys, only the Block 30s tested them afaik. Gaijin however decided both can for some reason, so if it comes expect it on both the C & D Barak IIs, which both have the regular Derby ingame already.
It would be incorrect. The latest AMRAAMs the IAF uses are the Aim-120C-7 and Aim-120C-8 (the export Aim-120D) last I checked. Wouldn’t be crazy wrong tho, like the Baz Meshupar and Barak II C having the Aim-120A when the IAF only ever got the Aim-120B as its first AMRAAM.
Every plane that has the Derby right now can carry I-Derby incl ER. It is not just limited to the both
One more reason to grind for that sweet South African Gripen C
I think we’ve already discussed this, and regarding what the “I” (improved) stands for, I’m sure a version for the game would be the I-Derby with a better seeker, longer tracking time, and better resistance to countermeasures (ECCM). That would make it much better than a regular Derby because, personally, I think the Derby has flaws. On the other hand, there’s the distance. The Derby and the I-Derby should both be over 50km, but that never happens with the Derby. It could be improved a bit with the I-Derby. I say this while the I-Derby-ER (over 100km) is being added.
Uhm, I didn’t know that, but then maybe it’s the C8.
Of course, I forgot to add the F-5TH TCU. But I don’t think this F-5 will have the I-Derby-ERs.
do israeli f-15s carry derby irl?
tbh ive mostly seen them on f-16s and israeli export upgrades
I don’t think so, for what I can gather it has only been fitted to the Israeli F-16 Block 30 and export platforms from foreign air forces like India, Colombia, etc.
Do you have a source for that? Last I checked I-Derby integration = I-Derby ER compatibility, but I’ve got nothing to suggest anything that uses the regular Derby can use the I-Derby series
The R-Darter is not the Derby, it’s almost identical but it’s not the same. The South African Gripen will not get the I-Derby or I-Derby ER ever, as it never got them nor could it use them.
They didn’t have or use Derbys at all in Thai service actually. And as mentioned in the message before this I have nothing on I-Derby compatibility for aircraft that are only known to be Derby compatible. Ofc the Thai F-5s are the most modern of the modernized F-5s that are Derby capable, so many they were integrated idk, still no sourcing on it so absolutely don’t expect it.
No IAF aircraft carried Derbys in service, as for testing that was only the F-16C/D Barak I (Block 30s). The F-15s won’t be getting Derbys ever I reckon, unless Rafael does some testing of some sort.
In-game it’s almost the same, that’s why I said it tbh.
That’s fine, but the SA Gripen C won’t get Derbys and I’m just making sure that’s clear is all, making sure there’s no confusion and a spread of misinfo. Theres always hope it could get the Aim-120 the, but there’s no Derbys to be added for it like ever
I actually found this and I’m not sure if it’s 100% real, but it is what it is:

I’ve done quite a bit of research on this topic of Israeli export missiles and I’m tempted to say that only Colombia and India possess the Python 5 and the I-Derby-ER for their aircraft.
