Well, the projectile is a sabot design that Bull designed in his work in
Canada, and he also developed mechanisms to inject gasses into the wake
of the projectile to reduce decelleration (as well as full rocket
systems). Bull's entire life focus was on developing a gun to put things
in orbit, and he didn't care who funded him. He did not figure on
Hussein using his gun to deliver bio or nuke weapons, or perhaps he was
hoping that someone in the west would outbid Hussein in keeping him
1400 G's is not extremely difficult to harden the projectile for, but I
suspect Bull had hoped that it would be beyond Hussein's ability to
produce mechanisms for bio/nuke attack that could do it.
