Why? Solid rockets can be made rather large.
Yes - but, as it mentioned above, with the fuel, that Safehold couldn't produce in anything more than laboratory samples.
And also, the burning process of big solid fuel rockets need a lot of complex construction works, that the Safeholdian technology simply wouldn't be able to do in neccesary persision.
put up more projectiles than the OBS defenses can physically shoot down in the window they have.
Probably that would need hundreds of millions projectiles. Because your chances that even one unguided rocket - without any control! - would be aimed near the OBS platforms is pretty low. Space is big.
So for low orbits the propellant/mass-ratio needed is immensely less, and still much less for higher LEO-orbits (where I think the OBS probably is... balancing stationkeeping needs with a short orbit time for rapid response).
For what reason the OBS should be on the low orbit?
