Depends entirely on what you want to do and how you want to use them. Hindsight is easy. But there was skepticism during the Afghan era that drones were useful for more than surveillance and a few strategic strikes. After all, nothing like being able to talk to the pilot overhead and walk his/her strike onto the enemy you see in front of you. And lest anyone think it's just our military, consider how unwilling the Americans are to give up their A-10s. We've gotten around to understanding how to incorporate drones better. That's the change. Part of that is the improvement in drones themselves. Better sensors. Better and more flexible weapons loadouts. Better airframes. Etc.But the capability needs to be there.
Because we didn't need armed drones for overwatch.I believe the IAI Heron that we leased in Afghanistan were unarmed and incapable of such.
I doubt that would be controversial. How do you hunt subs without dropping torpedos?I think many don't realize the Cyclone and Aurora are both capable of air-launching torpedoes.
