SM3 Missile

[domox]

One more, this time it's a preview video of what i've built so far. Note the third stage is empty and does not contain the kinetic warhead...

[jedelman]

Wow, this is really cool! I can't wait for this to be implemented.

In the mean time, can you share what info you have on the intercept algorithms that are actually used?

[KAPbl4]

Can you make non-pod version of the warhead? Or maybe standalone space-to-space\space-to-surface missile?

[Xel_AI]

I got an idea - but it requires MechJeb.

I remember that mechjeb works on all parts it's connected to even when disconnected from the main module.... so you launch the rocket , and when it runs out of fuel , you can autostage the whole rocket and turn it into a volley of debris.

I've run out of steam on this one, I've been thinking about releasing the stages, but the difficulties in coding an intercept has sort of made the hardware moot.

[Lazurkri]

have you talked to the Mechjeb guys? they'd probably be able to help you out!

[MaverickSawyer]

Nice work! You should also team up with Gaby to use this with the submarine.

[Lazurkri]

is this dead? Please let this not be dead, it had POTENTIAL.

[Millst0ne MK II]

+1. Me want missile!

IIRC, MechJeb's launch autopilot already has the "time launch to rendezvous" option, and that can reliably put you within 100m of your target if it is in a circular orbit of 0deg inclination, only issue is that you need a liquid fueled engine for the final stage (the one that sets the orbital Ap and circularizes the orbit) because MechJeb doesn't have the code to do the real SM3's little "spiral" it does at launch to basically waste just enough fuel so it burns out at *just* the right time to put the KE warhead on the right target

[The Destroyer]

No one let this die!

also,

its 9/11 today.

[MokStar]

If this ins't dead, be sure to add a nose cone camera view.

[Warshawski]

I sure hope this isn't dead. I built an SM-3 launch unit already.

Hey there everyone. I ran out of steam working on this. I just don't have the c# chops to write a good guidance plugin, or the math chops to port the algorithms I have to c#. One of the reasons I wanted to do this correctly instead of just through mechjeb rendezvous is that for the collision to obliterate the target, you have to have a massive difference in relative speed. If anyone wants to team up to get this bad boy operational I'm game. Until then I could release the models and such but the project just doesn't have the same luster without the promise of accurate behavior.

[Leon_Brooks]

send it over to Romfarer. He has a guidance system that is (mostly) operational.

I may have a chat with him.

[domox]

I've committed my efforts to github for everyone to have access to. I've also spoken with Mr. Romfarer and there may yet be hope for this project.

Please file any issues/suggestions on github.
