Popular Mechanics highlighted a few stories in the world of DIY weapons lately that’re worth looking at. Sort of a mashup, but to distill down: an ISIS workshop in Mosul was found with a number of DIY weaponized drones. This follows a February find of a workshop in Ramadi complete with vehicles constructed of plywood and styrofoam. The Mosul site included a peculiar model that looked to be a fixed-wing drone with attached quadrotor and PM speculated that it was either a mothership kind of design or for dropping boobytrapped quadrotors.
I’m left wondering if it was some sad attempt to create a fixed wing/VTOL hybrid, able to elevate vertically without runway or human launch but then take advantage of fixed-wing speed and stability like a Harrier.
Another part of the Popular Mechanics story was from Syria, where a refugee camp was hit by miniature guided bombs that appeared to be at least partially 3D-printed. They lacked engines but did apparently have working servos to operate fins and provide mid-course correction or at least stabilization, reportedly dropped from drones. I’ve been expecting sophisticated 3D-printed ordnance from insurgencies for a while but assumed they’d be in rocket form – perhaps it’s just easier to drop from above and guide in than launch and propel, plus the launch site has a better chance of staying undetected. The problem with assuming these latter are insurgent bombs though – aside from the fact that the Syrian regime is happy to kill refugees at their leisure – is that the height you’d need to drop them from to allow for any kind of vertical guidance is considerable, higher than the typical quadrotor. ISIS obviously has fixed wing dronecraft but the level of sophistication involved has me wondering.
Given the previous evolution I talked about involving ipad accelerometers to aim mortars in Syria and Raspberry Pi-powered missile launchers in Ukraine, when we were barely producing single-shot 3D printed firearms a decade ago, we’re likely to see more innovation in this area and to terrible effect.
