Project Pocket Sand

Project Pocket Sand was a project that was attempted by the town of Gestapo. It involved constructing a giant, three layered sand cannon atop an airship. The airship in question was never built, though plans were made and the name was chosen as "The SS Fuck You". The idea was that the cannon could launch the sand onto enemy airships, thereby disabling them and rendering them useless until the sand was manually cleared off. This idea was also considered for usage around the base of Gestapo to disable enemy airships flying into the town's airspace, but the idea ultimately never came to fruition.
