man "That thing we're building out in the desert like half a kilometre, long biggest gun ever, Tinker toy I don't care about it I hate how small it is it upsets me and makes me feel inadequate I must have something that is even girthier!" fucking legend

This man is a proper mad man. He will die one day being really happy while doing mach 20 in his garage. Good luck guys!

15km long accelerator.... this sounds like a pipe dream

I can’t imagine how excited the DoD are to test their hypersonics on the ground when this will be finished

A 10m boat tail will be under the booster for ~1ms at 8km/s. You folks are probably going to revolutionize gas valves just out of sheer necessity.

Curious if a standing wave inside the boost bottle stage could be used to meaningfully densify the shot.

A lot of people seem to be drawing parallels to spin launch which I agree has a similar USP to this. Although the acceleration loads and atmospheric heating leave a lot of questions about what could actually withstand the trip. Seems like a good system for commodities transport (thinking raw materials for construction). However, if you used this on a lower g planetary body with no atmosphere then I could see a lot more applications. Will be interesting to see how these ideas progress.

They’re basically making an advanced potato gun, but I love it

I knew about SpinLaunch, didn't know that there is another startup trying to shoot stuff into space. Great video, keep up the good work.

This sounds like a really fun company to work at. Not to mention, I love the side propulsion idea.

So I am going to presume you studied the works of Gerald Bull and the "Busy Lizzie" (V-3) at least. I am SO very happy to see someone pick up the idea of a true Space Gun once again.
I am hopeful that you obtain enough defense and test contracts that you will be able to see the project to fruition and have a viable working design delivering thousands of kg to orbit.
Peaceful Skies

This was one of the best explained episodes to date! Lots of good details visuals and explanations.

I've always wanted to see somebody pull this off. I really like these guys mentality behind all of this stuff as well.

How do you actually point it at the sky without tearing apart the payload and gun? 15 kilometers in 2 seconds, while turning to point at whatever angle toward space will utterly destroy everything involved. This company is being funded for their missile testing in a straight line possibilities. And for that purpose, I think they are doing amazing work! Maybe there is a way to cushion the corner and they’ll figure it out.

Is there any evulation of burst disk bursted geometry? Basically do the fins in the bursted disk have an impact on flow? Could they be used for example, to spin the air and create a rifling effect. Awesome story. S3 killing it again. Keep on building!

2 seconds to space speeds.. what payload can survive that acceleration?

This sounds like the work of Gerald Bull the inventor of the Babalon and Babylon and HARP gun.

I’m intrigued to see the projectile meet atmosphere at orbital velocity.

Good luck.

If in doubt, flat out 🤘

15KM is a lot of length, what about the size and maintenance? This will be interesting to follow and see if it happens.

I’m a pipefitter, can I please come help on your projects because I wanna be able to tell my grandkids I worked on the space gun 😂

I can't wait to see this working sending payloads to space. Godspeed!
