While I was home for spring break, I decided to throw together another quick pneumatic cannon (AND actually start on my first hybrid! but that's a whole different topic). It's a Toro P220 3" valve smashed onto a 4" by 10' chamber.

Very nice... and to be turret mounted 
 
More battleship turret than bomber turret though... wouldn't you want a multishot? I'm sure you can remove half the chamber volume and not lose much energy while getting much faster refill time.
Maybe have an automated round dropper like the Dragon Fire

Nice cannon! 3" bore, that's awesome, did the pool ball need wadding or a sabot?
