The pace of innovation, across multiple geographies, does not make the risks of it being the stuka. Rather it is stuka was part of an industry that saw biplanes fighter and bombings launching from aircraft carriers, fixed landing craft dive bombers, and open cockpits italian strategic bombers in 1939. 6 years later we had guided flying bombs and jet aircraft and pressurized cabins. The pace of innovation was amazing..fundamental material engineering, design, innovation, on and on.
My point is that there are multiple technologies in development right now that will likely make drones less effective by the next war. We may be seeing a window where there is a new technology, but the technologies to effectively counter the new technology isn't there yet.
There will be edge cases where drones will be effective when the counter measures are absent, but I suspect overall drones will be less effective in the next war.
The pace of aircraft engineering was quite high in the 1930s and 1940s. Early in the war some very obsolete designs were in use due to this pace. The British were still flying some Gloster Gladiators and the Hawker Fury had just been retired. At the same time the Spitfire was coming into use.
When the Germans invaded in 1941 the most numerous fighter in the Russian arsenal was the Polikarpov I-16 Rata and they even had some I-15s in service, but they also had a relative handful of MiG-3 fighters.
The biggest problem the Ukrainians are having with the Iranian drones is that they are easy to shoot down, but the missiles the Ukrainains are using are more expensive than the drones. Because the drones are going after important targets, the Ukrainians need to shoot them down, but they expend an expensive missile to do it. I think it was Trent Telenko who made the case the Russians are doing the drone attacks as a form of SAED on the Ukrainians by forcing them to use up their SAMs.
What they need are cheap ways to shoot down these drones that make it much more cost effective. In development are electromagnetic weapons, small missiles, radar directed guns, and I believe a system that can fire different types of AA fire depending on the target, a small missile or gun for a drone, or a regular SAM for a manned aircraft.
I thought a good stop gap would be Hind helicopters. They have a chin turret gun and can match speed with the drones.
