What craft are those? I recognize the Aquila landers, but the ones that look sorta like Fury interceptors look...off, while the big one in the back with a bunch of underslug weapons is unidentifialbe for me. Unless it's a thunderhawk.
Expensive enough they probably cost more than the ship that carries them. Pretty much only the Inquisition has access to them, and then, not regularly. Though the Imperium has never really been good at cost calculations, anyways.
And besides, you can't get any plunder if you blow up the planet.
