Its funny they think you has to choose between dominating small UAV and dominating "proper" UCAV like GJ11
The piece was written by a retired USAF general and its basically the airforce equivilent of American old men arguing against computers in cars
Also its hilarious he used B2 deployment againt Houthis as argument for the need for expensive bombers... He proberbly wrote this in response to the recent NGAD article
I'm not saying that one has to choose between small UAVs/quadcopters and larger more proper UCAVs like GJ-11.
I'm saying that for high intensity, air/naval/missile conflicts, the former are much less relevant and impactful due to their inherent limited deployability and range and payload and signature, whereas high end capabilities such as strike fighters, bombers, long range missiles and long range high end UCAVs are more important.
The use of B-2s against the Houthis are very much somewhat overkill and could've been done with other means, however it is also a demonstration of the role that VLO long range bombers have -- being able to conduct a long range penetrating mission against a foe in permissive airspace sounds easy, but doing it in a way that no one else in the rest of the region is able to even be aware of is more difficult.
In a high end conflict, that sort of capability will be the minimum even if you want to conduct standoff range rather than penetrating strikes.
