Docking and deployment mechanisms! Couplings that can be released to set the cannons loose. We could design an entire system for the deployment and retrieval! If they're remote controlled, we can dock them using the shellphone too!

They'd just need a smaller internal engine to give them some mobility so they aren't free floating! Like...like motorized buoys!
