    Thats what I was thinking of, you still have to deal with building a hugely tall structure though, because the exit must be above the thickest part of the atmosphere

      Most or all of it. To be at orbital velocity the projectile would be moving at 30 km/s. Even a small amount of gases would be a like a brick wall.

      Hugely tall and extremely rigid, because if it wobbles while the projectile is moving through it, it will tear itself apart.
