I'm not going to say its bad, just that if you want to make a MOAB (mother of all bombs) You should try to make it just as effective as a smaller missile/bomb but with the same Explosive force. Try completely cold deuterium, or plutonium fission bombs. Look for my missile/rocket designs, they are free to use with credit, and they work great for bombs and such things like that. Try designing a multi stage rocket that is remotely operated using wifi. It should work good, just add a liquid fuel engine, remotely operated, and the explosive warhead in the top. If you don't understand how the materials work, look on TPT wiki. :)
