i probably messed up my maths then
You can also check it directly in the missile spreadsheet. Both SR and ER have about a 240s specific impulse (similar as Ns/kg but normalized with the weight of the propellant instead of the mass) for either booster or sustainer.

Last time I’ve looked into missile sheet it was lacking Derpy ER.

I am really disappointed that we aren’t getting the Derby ER on aircraft even though it only features a marginal performance improvement over the regular variant
It would’ve been such a cool gimmick but I guess we can’t have any nice things
We have absolutely nothing on it using different propellants iirc, just stages. The increased efficiency comes from the stages self managed usage
I’m aware, double is stated for both ground and air. Interestingly when it comes to MR equipped missiles it only increases ranges by 20km, it doesn’t go up beyond that there strangely
Are we sure in this being a thing or is it a prediction
350m/s, my bad

Aim120B, Aim-120C-5, Aim-120C-7, Aim-120C-8. Possibly D variants as well but these are the variants I’m aware of the IAF equipping

To me it’s just a huge NO! If such aircraft never ever tested or used a certain type of weapon then it should not have it in the game. Giving ahistorical loadout isn’t a solution especially if it’s for balance purpose.
I am among those wanting historical loadouts for aircrafts, not fictional ones
Except it was. The F-16I has the capability to carry almost if not everything airborne Israel has (that can be put on it ofc).
Considering the Barak can carry them, the Sufa can guaranteed too.
This is also without even bringing up the “compatibility” thing, which just makes the chances even higher.
Anyway, yea it would be a good addition once the 120D, PL-12A, MICA and such are fully fixed too.

in that case… It should have them. gonna change my vote so. And thanks for your info. always glad when someone can reply with facts!

I think this thing will be happened if they give the Upgraded F16I with aesa radar then bring I Derby ER cause now F16I is don’t have aesa
That’s an F-16D (thus I made Giving the F-16D its I-Derby ER )
As it currently stands, the Derby ER only offers a marginal improvement over the regular derby so it still wouldn’t be able to compete with top tier missiles
i think that is a sign for me to go to sleep

The problem is that we still don’t have anything explicitly stating the Sufa in particular is compatible with the Derby series. Not even all the Baraks are presumed compatible, since only Block 30 testbeds loaned to Rafael mounted and tested them (which is enough for them to be added to the game, as if a single in service example is modified or tests a weapon, the vehicle ingame meant to represent all examples of this vehicle as a whole can get them, hence the tested centerline Aim-9D for the Shahak report). Sadly we don’t have that luxury for the Sufa, and given past report denials we’ll need it for this as the devs are being a bit of a stickler about it
Now we might be able to get something out of this if we can compile a proper report based on the “compatible with everything” thing and if the Derby is apart the IAFs arsenal, but I’m not sure about the latter part
Same. The real question is how did they achieve double the range? (Unless it just propaganda, but first let assume its not)
IRL?
I’d hazard a guess its combination of some improvements to the propellant (higher specific impulse), maybe higher mass of propellant relative to missile weight (lets say its 55-60kg instead 47, courtesy of significantly more compact electronics) and creative interpretation of “maximum range” ie “missile has 40km range only when fired at fast moving, high flying, non evading target, with actual distance traveled being around 15-20km tops”
Derbys seems to have greater success as air to ground missiles than air to air, so “adjusting” ranges for threats of ballistic missile variety, that tend to fly faster and higher than usual military aviation also helps “extending range on paper”.
Literally what theyve known for the entire history )
- Kh-38 on su-25Sm3
- double racks on Su-27SM
- double racks on Su-30SM
- double racks on Su-30SM2
- R-27ER/ET/T on MiG-29 (9-12/9-13)
- Yak-141 in general
- 8x LMUR’s on Mi-28NM
Oh wait, its an USSR. Acceptable for them.
I think its reasonable to assume the increase range is not a result of max range interpretation, considering that can be done to the normal derby.
Thats not how rockets work. Solid motors haven’t improved their mass efficiency because you really can’t with phyisics
