In 1963 General Dynamics put a few charts in front of NASA showing the sort of military payloads that Nova - with about a million pounds payload - would be capable of. This included chucking infantry and "police" forces, 3,500 ABM satellites, 10,000 megatons worth of nuclear weapons, enough chemical weaposn to kill 1,000 sq. miles, enough bioweapons to kill 1,000,000 sq. miles. Details are lean; like as not this was not much more than thinking out loud.
