Given that the drone is going on a one way trip, I imagine you'd want to use the cheapest hardware possible which would mean using the dumbest model you can get away with.
Wait till you learn how much missiles cost.
Your drone needs to be cheaper than what you're killing, so if your target profile is 50k+ USD and up, a $10000 even is fine (not that it would need to be even 10k).
Depends on the value of the target. Costs Ukraine $918 to kill a Russian soldier[1] but if you’re using a fully offline automated swarm to destroy a petro system worth billions then what’s a few GPUs strapped to each one to run local models.
