I'm trying to come up with a stealthy, jet powered drone similar to the "Hopeless Diamond" (and other variations) - since all I have so far is in my CAD software, I wanted something I could start putting together now.
The Ukrainians have had amazing success with low cost drones, drone swarms as well as high speed drones to take out Shahed and similar drones. They've even taken out a Shahed with the STING drone at a 500km range. Here are some of their drones:

I noticed that the drones on the left side look familiar.... The old (1958 issue) Revell Tactical Missile set has a Little John rocket as well as four Dart anti-tank missiles:

The rest of the Tactical Missile kit has some of the issues you'd expect in a 68 year old kit (even if it's a reissue) but it still holds up well and most of its sins can be fixed with some sanding and putty:
