light the fuse and hit the deck

Well, these are the general scematics for the rockets that could be fired out of the Cannon.
.
This is the first:

I initially thought that the center was a good place to put the payload, but changed my mind.

((next slide please))

Design Two:

To shift the primary weight to the front, I decided that the payload being in the nose would be a good idea. There is also the fact that you can fit more in there.

((next slide please))

Rocket design three:

Changing the shape of the nose slightly to allow for more space, I thought that making a core of explosives surrounded by some sort of shrapnel. Just a thought that occured to me.
((end slide show))

((Disclaimer: No representation is made that any of the images you see will ever be put into use... but no representation is made that it won't either...))
((But the Cannon itself is a definite maybe: that things just cool. Just gotta get the time))
