I don't think the founding fathers anticipated rocket artillery or specifically planned on making it part of the Second Amendment.
"... and the rockets red glare
the bombs bursting in air...."
I would have to disagree with that. The 2nd Amendment covered the "cutting edge" weapons of the day. Certainly the IDEA of more effective weapons were as apparent to the founding fathers as LASER GUNS are to us. I wonder if they could have imagined DEATH RAYS, AND LASERS, but guns... No problem. The idea of a machine gun was invented along time ago, a lot closer to their day than to ours.
