minus-squareskulblaka@startrek.websitelinkfedilinkEnglisharrow-up25·6 months agoI may risk being too credible here, but a $80 drone is a lot more expendable than a $40m laser tank. The drone can be considered a consumable. Hell, mark the drones down as ammo.

minus-squaremindbleach@sh.itjust.workslinkfedilinkEnglisharrow-up8·6 months agoIn all seriousness, wavelength-specific dielectric mirrors can approach six nines of reflectivity. The hard part is hitting the mirror instead of the drone.

minus-squaremindbleach@sh.itjust.workslinkfedilinkEnglisharrow-up3·6 months agoYeah I guess you can’t pulse-ablate a mirror made of plastic. Though it invites a backup strategy of spraying your enemies with molten drone.
