Teach me how to calculate Zuni rocket release range in direct head on

I enjoy using Zuni with proximity set to 1000 meter and get some occasional kills, especially on T2 with 16 zuni rockets. According to my experiments, on ground level, with full speed on both my and enemy plane, if I start to shoot from 1.5 km on head on and use all rockets as fast as game allows, I get the kill.

But what is the exact formula? Should I add my plane’s speed to rocket’s starter speed and max speed? I know enemy plane’s speed def matters, but not quite sure about my plane’s speed.

You know, Zuni rockets are for air-to-ground, right?

You know, they can explode in the air if you set its fuze right. Damn, such a waste of reply.

They are designed for both A2A and A2G purposes, Zuni has a long history including air to air use.

Yes your planes speed matters as well, if you are use to throwing them in a mach vs mach headon and now instead you are going mach 0.3 headon vs a plane going mach youll have to launch sooner how much idk maybe 100-200m or so? Idk

For practical use this is just going off feeling, aside from speed aspect should also be taken into account if you want to use these other than headon.

From my expierence as well fuse setting can matter too, shorter fuse times seems to yield more accurate or consistant results, but when headon limits your time to pull away making it more risky.

Honestly I feel like trying to get the accurate formula is going to be more time consuming than just get a feeling.
Basically if the closure rate to target is positive (you are approaching him), you need to fire sooner. If it’s negative, you need to fire later.

But it’s also dependent on your own speed to some degree, because if you go fast the Zuni might not travel away from your plane as far than a lower launch speed, because the rockets might reach their top speed faster and plateau.
