alt Hacker NewsUkraine is using old school propeller trainer craft to shoot down some of the slower Russian drones. https://theaviationist.com/2024/06/26/ukrainian-yak-52-kill-... There's usually new footage of this every week on social media.
Don't really see or hear about the USA building or using propeller driven planes in military outside of special ops.
It isn't reasonable to expect that propellor drones will be used long term - they are too easy to shoot down. you need just enough ability to force the enemy to not waste they energy making them when something more expensive is harder to shoot down and thus more likely to work.
