While it's clear the US is working on those types of drones too (cloning Shaheds, basically), the likely mission profile of the US requires we have that capability. Pick your potential future US conflict and it won't look like us flinging disposable drones over the border at Canada, but rather needing to project power from an aircraft carrier or forward base against an adversary, where range, payload, sensors, and more matter. Quantity has a quality all its own, but there's no world where the US doesn't need a Reaper style drone in the arsenal.
> potential future US conflict
I'm not sure if "future" is a good word for the widespread civil unrest, nascent insurgencies, and very normal soft-target gun battles that happen weekly here, but our "US conflict" looks like street-to-street fighting, within our own borders, with people who are already here.

Right, I can see the need for both, but that suggests to me that they could differentiate the sensor package + loiter drone significantly from the shahed clone (which, given that it is a one-way trip, has a very similar operational radius)
Does one really need to bring along 2,500 kg of ordinance, when we can launch another $50,000 shahed-equivalent at whatever hard targets the loitering drone locates?
