Loitering weapon
Some of these weapons are capable of making decisions on whether to hit a target or not, on their own. If no human being is involved in this decision, this raises a number of ethical issues, and problems with international law. In many respects loitering weapons are not comparable to a missile, that is fired at a target. A loitering weapon may spend hours waiting for a target to appear. While it may request final clearance before the hit, this does not have to be the case. In other words: With a loitering weapon, there may be no human who decides what target is hit.
