Tad short of velocity to make orbital altitude even with a perigee kick engine.

Sounds more like a giant centrifuge. “rotational acceleration method”

[Steve Van Doorn]

Railgun with the projectile a large spinning corkscrew. Likely using a much smaller rocket to maximize altitude.

Cannon launch systems didn't work out to well.

[Campion]

A rocket launch pulls 4-8 G's. This thing -- according to the article -- would pull 40-60 thousand G's. Most things would turn into mush under that acceleration. How heavy would a satellite have to be to be "G-hardened" enough to take 60,000 G's?

Sounds like a weapon.
