A dedicated pirate ship, with dedicated slots for:
- smuggling cargo: it's like a hidden/shielded cargo, space that cannot be scanned by authority vessels
- grappling hooks: each one slow down the target ship by a certain amout; if the difference in size is big enough, the target ship will stop completely
- super-cruise inhibitor: yes I know that missiles exist, but this module would be like a bubble, as long as it's active, no ship can enter supercruise, including the ship that activated it
- drive breaker limpet controller: like a hatch breaker. There's no reason pirates wouldn't want to develop a specialised limpet that targets drives (we have limpets for everything after all)
Well, you asked
