DropForce, a Vienna Start-Up Building Drones in a Suitcase, Lands Investment

Vienna’s DropForce Systems is betting on a simple idea with messy consequences: if drones break in the field, maybe the answer is not a bigger factory, but a printer in a suitcase. The start-up has built the STURM 01, a modular F.P.V. quadcopter that can be assembled without soldering, plus a mobile production cell that fits into a transport case. BarnVentures has taken a 20 percent stake, and together with LNX GmbH has put in a solid six-figure investment. Until now, the founders had been financing the work themselves.

The company was founded in Vienna in early 2026 by aeronautical engineers Jakub Hamdard, now chief executive, and Christian Mühl, chief technology officer. Both trained at HTL Eisenstadt. Hamdard worked on satellite propulsion at ENPULSION and later as a project manager at Diamond Aircraft. Mühl worked in production engineering at Schiebel, Airborne Technologies and Diamond Aircraft. Their first plan was light-show drones, but they say Chinese systems were too expensive and too unreliable. Four prototypes later, they realised the hard part was not printing parts. It was assembly, especially soldering.

So they redesigned around the workflow. The central circuit board is part of the structure, the flight controller and motor controllers are in-house, and the rest is split between plug-in electronics, screwed mechanical parts and 3D-printed structure. DropForce says the drone can be assembled in 10 to 15 minutes, depending on experience. A 3D printer takes about 20 minutes to print the parts for one drone, which means the next unit can already be coming out while the last one is being put together. In continuous operation, one printer is supposed to produce parts for more than 70 drones a day.

The bigger idea is the Tactical Case: a single-person kit with a 3D printer, power supply and tools, so users can make replacements on site instead of waiting for orders and delivery. Longer term, DropForce wants larger cells with several printers in vans or containers. It plans to sell finished drones and production cells, but the real business is meant to be the steady flow of kits, components and mission modules. The modules already include FPV flight and light shows.

DropForce is careful with its “European Sovereign UAV Systems” label. The board layout and electronics are its own, and it is building a European supply chain, but motors and standard parts are still bought in, and rare-earth magnets remain heavily dependent on China. So no, this is not a fully European drone. It is a European attempt to reduce dependency without pretending the dependency doesn’t exist. The company has no paying customers yet and is looking for pilot users, while a patent application is being prepared and more funding or a strategic partner is being considered.
