alt Hacker NewsNew (Russian) versions of Shaheds are jet propelled (much faster), have high-quality remote control, and as some claim, AI-based computer vision. So old interceptor drones are not working anymore. And the country can manufacture them at much higher rate than the other country can manufacture patriots.
The new jet powered Shaheds are more expensive as well. And Ukraine is already having good success in shooting them down without patriots (which they are very lacking in) - these are new drones that they just designed for the task. These new interceptors are more expensive than the old ones, but still cheaper than patriots by a lot.
We know Ukraine is working on a not a patriot interceptor that can do ballistic missiles, but so far there is no word on progress. (this seems to be intentional - they are not saying why but experts have some good guesses)
