A way ahead of the UK in its thinking ~ understandable given its proximity ~ Germany not only builds drones in materials like plywood, but is building a distributed network of manufacturing sites to supply them in great numbers. The UK policy is importing its needs, which is of course the worst possible preparation for defence and the reason it had to import US assistance wholesale during WW2.
For the figures are astonishing. Between them Ukraine and Russia have deployed some four million drones during the course of the 'special military operation', which eclipses the number of aircraft deployed in WW2 by a very large margin. WW2 effectively gave us aeroplanes as we know them today, and the current conflict could be said to have done the same for drones.
Ukraine purchases as many as 10,000 drones per month from DJI to supplement the 100,000 that some of its factories already produce. Meanwhile Germany's Helsing HF-1 seen above is financed largely by the founder of Spotify, so many of you are involved in one way or another; the author of Linux via which you may be reading these words did point out that all technology conflates military use and entertainment.
The Russia's Molinya (inset) also features plywood and alloy tubing, and is available via Italy as a scale model that you can own for yourself for less than $100:
Neighbour's dog annoying? Take it out with a drone! (Munitions and goggles extra).
