I move that we take 40' cargo containers, make drop sides for them, install a Vulcan and a Mark 19 or two with several basic loads of ammo, tie them into the ship's radar, and put the containers with crews on board transiting ships with a squad or two of grunts for good measure.
Any small craft with hostile intentions approach, you power up, wait for them to get within range, drop the sides and light them up.
Anyone who survives, gets fragged and chummed.
We can install the loudspeakers on the Vulcan mount. Read them the resolution after the mad minute. Wouldn't want to violate any UN ROE.
After the first few weeks, you can put empty containers on the decks of every ship and let the wannabe pirates try the shell game, if there are any still alive and willing to come out to play.
