The Interwebs seem to indicate that that’s only if you give it a laser spot to aim at, not with just GPS.
Good catch.
Agree grenade sized munitions won’t damage buildings, I think the conversation is drifting between FPVs and other kinds of drones, and also between various settings, so I’ll just state my beliefs.
Fiber FPVs with 40km range and 2kg payload (either kamikaze or grenade/mine dropping), which can eventually be countered by a large number of short range guns if they fly at low altitude. It’s not clear to me if the 40km range ones need to be larger
Heavy bomber drones can be equipped with fiber (or Starlink for US allies) and carry 15kg+ payload, enough to damage buildings and sensitive industrial equipment. They can do this while flying above the range of small guns and need dedicated antiaircraft guns
Fixed wing can carry even larger payloads with longer range and higher altitude, but are still pretty slow, except for the ones with jet engines
Drones equipped with GPS will know their position to within ~10 meters like the GPS only variant of Excalibur. It seems possible to constrain the payload’s horizontal velocity by 1 m/s on average, and the drop time from 1500m is 17 seconds, giving an error of 17 m. The overall error would be sqrt(10^2 + 17^2) = 20 m. If GPS is jammed, it’s not obvious they can do the first part, but probably they can still use cameras or something
All of the above are extremely threatening for both organized warfare and terrorism against an opponent without effective cheap air defense.
Even with the next evolution of air defense including radar-acoustic fusion to find threats, the limited reliability of ~all types of existing air defense and large number of drone configurations makes me guess that drones will remain moderately threatening in some form. Given that Hezbollah was previously firing unguided rockets with CEP in the hundreds of meters, some kind of drone that can target with CEP around 20 meters could be more cost effective for them if they cannot procure thousands of cheap guided missiles. If they could drop six individual grenades on six people from a bomber drone even in the presence of air defense, that would be even more effective, but it seems unlikely
Excalibur is made by the US, which has no incentive to reduce costs, and so its $70k price tag is more of a “maximum the army is willing to pay” situation. This is true to some extent with Skyranger so maybe someone motivated will build smart ammunition that costs $40 per round and make it cost effective.
