It is striking to me how small the payloads are for these drones - up to about 25kg.

There's a lot of talk about how cheap these drones are - and indeed they are. But the payload is like 1/20th of a classic cruise missile too.

If they are 100x cheaper, then sure, this maybe a decent tradeoff (depends also on reliability, probability of getting destroyed etc.) but it's not like a small drone is just as good as a big and very expensive cruise missile.
