How can you be so sure when there is barely any official info of the Stunner. All that is stated is “high manoeuvrability” and that it has a advanced seeker, but nothing specific. What are your sources? Or are they just assumptions? As the 400kg figure was also never officially stated.
Also the Stunner has no proximity fuze at all, so it would be terrible in game.
Most modern interceptor missiles have similar level of classification. All we can do is believe the stats which are publicly available and some reasonable estimates. Stunner publicly available source shown the missile have 300km range, IIR and AESA MMW radar, 3 way datalink, 3 pulse motor, speed of mach 7.5. This is enough to determine stunner is better than buk.
I apologise my mention of 400kg weight, as I didn’t verify the source (it’s from website army recognition, yes I understand it’s not a reliable source). Still, a stunner is much smaller than a buk missile which is reasonable to assume stunner is much lighter than buk. Which suggest stunner is <500kg.

Also effectiveness of hit to kill is up to gaijin honestly, consider the new pantsir smsv (close to hit to kill).
I suppose trying to repeat Diehl/IRIS-T SL stunt and asking Rafael what they can share about Derbys wouldn’t hurt? Though native speaker may or may not look bit more credible than typical nigerian snail prince scam mail.
Spyder is going to make me have an stroke
Did that produce any results, I never saw the outcome
Guy certainly got a response with some specs that I presume were A-okay to go public, then got questioned in return if he can provide high resolution WT wallpaper of IRIS-T systems, as it impressed Diehl team.
Now whether values provided helped Gaijin, I dunno, but certainly IRIS-T SL saw quite massive buff to missile range during Dev cycle then?
Seems like the spyder radar gets more faster target updates on the dev
Though am more interested on what they are going to do with the derby er
Only one question’s why I Derby ER so slow since first second of launch ? (even below mach 3)
The problem is how much drag it has, it’s absurdly high and craps all its speed out once it loses its propulsion
The first pulse is very weak, weaker than derby SR. The idea of dual pulse was suppose to be saving the second pulse at high alt to minimise drag. I suppose the first pulse should loft more if the target is really far away.
This is actually sad not only it won’t perform well but this means gaijin will leave the spaa line like this for more than a year Israel should get a new spaa like HVSD/ADAMS there’s a huge gap from 9.3 to 12.7 and not mentioning that the whole tech tree spaa can’t defend against helis properly due to lack of saclos missiles
And 2 days ago the suggestion for iron dome was closed idk what that means I first it sounds broken if they added it then I learned that the new pantsir gets 96 missiles which makes the addition of iron dome not as bad of an idea but we’re talking about 2027 bc the pantsir must break the game and people must complain for a few months till something is changed
You’re a hero
alright so the I-Derby ER is still WIP, so probably it will act like an actual dual-pulse missile soon
It still feels so underwhelming compared to other top tier spaa’s
accepted, we hope this will make it better
I really like how we are talking about gaps in Israeli spaas, while ussr just recieved its 3rd absolute beast of spaa because two previous ones “didnt quite make it” according to bvvd.
Btw, spyder is a 11.3 material in its current state. If Derby er being properly implemented - 12.0.
S1 is 12.7. Stating otherwise - skill issue.
